Big Diamond, Perfect Color

October 16th, 2006

“A South African company bought the world’s 15th-largest rough diamond Monday, paying more than $12 million for the golf-ball sized gem found in the tiny Southern Africa country of Lesotho, officials said.

South African Diamond Corp., the overseas-based manufacturing arm of famed British gem seller Graff Jewelers, purchased the 603-carat stone for $12.4 million, said Lesotho’s Natural Resources Minister Mamphono Khaketla, whose government co-owned the gem with a private concern, Gem Diamonds.

“We called the diamond the ‘Lesotho Promise.’ We promise you more of the same and better in the future,” Khaketla told reporters in the Belgian city’s diamond district.

South African Diamond Corp. said it plans to turn the raw stone into one cut gem above 60 carats in addition to other, smaller stones, with a final sale price of more than $20 million. Experts have graded the stone “class D,” saying it is of the clearest quality, with no color blemishes.”

Ruby = Red Sapphire

March 30th, 2006

Did you know that a ruby is simply a red sapphire? Sapphires are found in every color of the rainbow. Every sapphire is made of the same substance – aluminum oxide. Pure aluminum oxide is transparent. Trace elements within the sapphire cause the various colors. Small amounts of chromium result in a ruby. Blue sapphires contain iron and titanium. The reason rubies are much rarer than blue sapphires is because there is far less chromium in the earth than iron and titanium.

Tiffany Sues Ebay

March 4th, 2006

Ebay is a marketplace that is full of counterfeit products. Be very careful when shopping on Ebay. If it sounds too good to be true, it probably is!

Excerpt from CIOToday.com article:

“Tiffany & Company, the famous New York-based jewelry retailer, is suing San Jose, California-based online auction firm eBay for allowing its Web site to be used to sell counterfeit jewelry.

The landmark lawsuit also alleges that eBay, in addition to facilitating sales of fake Tiffany goods, also makes millions of dollars from fees charged for counterfeit sales.

Two years ago, Tiffany bought several hundred items on eBay and found that three quarters of the items purchased were counterfeit.

The Tiffany lawsuit, which originally was filed in 2004 in a New York State court, is expected to go to trial by the end of this year, according to press reports.”

Man Made Diamonds – The Next Generation in Technology?

October 21st, 2005

Excerpt from USAToday: “The whole concept turns the fundamental idea of a diamond on its head. The ability to manufacture diamonds could change business, products and daily life as much as the arrival of the steel age in the 1850s or the invention of the transistor in the 1940s.

In technology, the diamond is a dream material. It can make computers run at speeds that would melt the innards of today’s computers. Manufactured diamonds could help make lasers of extreme power. The material could allow a cellphone to fit into a watch and iPods to store 10,000 movies, not just 10,000 songs. Diamonds could mean frictionless medical replacement joints. Or coatings — perhaps for cars — that never scratch or wear out.

Scientists have known about the possibilities for years. But they’ve been held back because mined diamonds are too expensive and too rare. And they’re hard to form into wafers and shapes that would be most useful in products. Manufacturing changes that. It’s like the difference between having to wait for lightning to start a fire vs. knowing how to start it by hand.

“I’m just so completely awed by this technology,” says Sonia Arrisonof tech analysis group Pacific Research Institute. “Basically, anything that relies on computing power will accelerate.”

Arno Penzias, a venture capitalist and Nobel Prize winner for physics, says, “This diamond-fabrication story marks a high-profile milestone on an amazing scientific journey.”

“We can’t begin to see all the things that can happen because single diamond crystals can be made,” says Apollo co-founder Robert Linares, elegant and slim in a golf shirt, slacks and loafers as he sits at the two plastic folding tables that make up Apollo’s low-budget conference room. “We are only at the beginning.”

Linares has worked on the technology for 15 years, much of that time in his garage. From the start, he did this because of the promise of diamonds in technology. Linares wasn’t trying to make gems. “

No Such Thing as 24K White Gold

October 8th, 2005

In jewelry stores, you may have seen many different varieties of gold including yellow, white, rose (red), and green. These colors do not occur naturally. Pure 24K gold is found naturally in one and only one color – yellow. The color of pure gold cannot be changed. However, most gold used for jewelry is not pure gold, but is alloyed with other metals. The color of the gold jewelry depends on what metals are used in the alloys. The copper in rose gold is what gives the metal its red color. The primary alloy used in white gold is nickel, which gives the gold its white color. However, it is very difficult to achieve a true white color since 14K gold contains 58.5% pure gold. The appearance of the white gold alloy will always be influenced by the yellow color of the pure gold it contains. The result is a color that appears white, but may seem to have a yellow cast when compared to a white metal like platinum or rhodium. How yellow the white gold alloy appears depends on the amount of gold in the alloy. 18K white gold will look more yellow than 14K white gold since the alloy contains more gold. 24K gold cannot appear white since it contains 100% pure gold. The slightly yellowish appearance of white gold was not a major problem in the past since it is only noticeable when compared next to a true white metal like platinum. When platinum became more popular in the 1990s, customers began to notice that their white gold didn’t look as white as platinum. Jewelers began to rhodium plate white gold in order to achieve a white color comparable to platinum. Rhodium plating of white gold jewelry has now become standard. The problem with this practice is that the rhodium plating does not last forever. Customers are often surprised when they notice that the back of their ring looks a little yellowish after wearing it for awhile. This is inevitable with rhodium plated jewelry. The rhodium plating will eventually wear away and will need to be replated by a qualified jeweler. If you want white metal jewelry that doesn’t need to be rhodium plated, you should stick with metals that are naturally white like platinum. Your other option is to have the rhodium completely removed and accept that your white gold jewelry won’t look as white as platinum.

Diamond Prices Will Be Going Up

September 12th, 2005

Being short one crystal ball, I am reluctant to forecast market prices on anything, but the circumstances that present themselves in today’s diamond market are compelling. A diamond importer who had recently returned from a diamond buying trip in Antwerp, described the market conditions as the worst he had seen in his lifetime. He told me that he was reminded of the diamond market of the late seventies and early eighties. During this time period the price of a 1 ct. D flawless diamond increased from a few thousand dollars to $70,000 in 3 years. He told me that he had customers willing to pay anything for 1 ¾ ct. and 2 ct., G-SI1 diamonds, but he couldn’t even find one to look at.

Here are some of the reasons we will probably experience higher diamond prices:

  • Increased demand from emerging markets such as India and China.
  • De Beers has increased the prices on rough diamonds eight times in the last two years. Cutters, wholesalers, jewelry manufacturers, and retailers have absorbed a significant portion of these increased prices by cutting their profit margins. Margins at current levels are not sustainable. Prices will probably increase this Christmas season.
  • In recent decades, many of the new diamond mines have produced small and low grade diamonds.

Below are the prices of selected diamonds for the years 1997, 2000, and 2005:

1.00 ct. D-Color Flawless-Clarity

1997 - $19,920
2000 - $20,159
2005 - $21,720

.75 ct. G-Color SI1-Clarity

1997 - $3936
2000 - $4128
2005 - $3,936

2.00 ct. F-Color Vs1-Clarity

1997 - $23,328
2000 - $25,920
2005 - $35,856

2.00 ct. L-Color SI1-Clarity

1997 - $8,424
2000 - $8,639
2005 - $8,856

It is easy to see that price increases are not spread evenly across the different sizes and qualities. I believe future price increases will be more heavily weighted to diamonds 1 ½ to 3 ct., I to K color, and in the Vs1 to SI1 clarities.

Diamonds in Canada, Eh?

September 10th, 2005

When you think of diamonds, South Africa might come to mind, but South Africa hasn’t been a major producer of diamonds for decades. In fact, one the rising stars in diamond production is Canada. Since major commercial mining operations began in 1991, Canada has risen to become the 3rd largest diamond producer in the world. Canada produced 15% of the world’s supply of diamonds in 2003. According to Statistics Canada: “Not only is Canada rich in diamonds, it is rich in high quality diamonds. From 1998 to 2002 roughly 13.8 million carats have been mined, collectively worth $2.8 billion. This is roughly a 1.5-kilogram bag of ice each day for five years, with each bag worth $1.5 million.”

The ‘R’ in Ruby Stands for Rare

September 2nd, 2005

Ruby is the rarest gemstone in the world, even rarer than diamond. In 30 years of attending large international trade shows, I have seen less than five decent quality rubies over 9 carats. By contrast, I could go to one diamond cutter’s booth that specializes in large diamonds and look at 15 to 20 diamonds from 10 to 50 carats. Although no one is keeping track, experts have estimated that rubies are 100 times rarer than diamonds. When comparing rubies and diamonds over 2 carats, my guess is that rubies are thousands of times rarer.

The Hope Diamond. Is it the largest?

August 27th, 2005

A common misconception is that the Hope Diamond is the largest diamond in the world. It may be the most famous diamond, but at 45.52 carats, it is not even close to being the largest. The largest faceted diamond is the Golden Jubilee, a monster 545.67 carat fancy yellow-brown diamond.

Synthetic and Imitation Gemstones - What’s the Difference?

August 23rd, 2005

There is a big difference between a synthetic gemstone and an imitation gemstone. A synthetic gemstone is a man-made gemstone. It is chemically the same as its natural counterpart. On the other hand, an imitation gemstone is a completely different substance. For instance, an imitation diamond may be glass, quartz, or a cubic zirconia. A synthetic diamond is chemically the same as a mined diamond, but it was made by man in a laboratory.

Synthetic and imitation gemstones are always less valuable than natural gemstones.

Who Keeps the Ring?

August 18th, 2005

Who keeps the ring when an engagement is broken? Jewelers Vigilance Committee addresses the issue in this article. Who Keeps the Ring? “The invitations were sent out, the wedding cake was ordered. Mary lost several nights sleep over the perfect flower arrangements and even more over her dress. Then the unthinkable happened. Her fiancé Paul called to tell her that the wedding was off. While Mary was still trying to digest the news, Paul casually asked her to kindly return the engagement ring that he gave her. She gasped and almost fainted on the spot. Hanging up with Paul, her next call was to her lawyer, just to make sure that her ex-fiancés request was absolutely ridiculous.”

Giant Cosmic Diamond Discovered

August 16th, 2005

From BBC News:

“Twinkling in the sky is a diamond star of 10 billion trillion trillion carats, astronomers have discovered.
The cosmic diamond is a chunk of crystallised carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus.

It’s the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk.

Astronomers have decided to call the star “Lucy” after the Beatles song, Lucy in the Sky with Diamonds….”

Jewelry Cleaning Warning

August 16th, 2005

Ammonia is a good choice for cleaning jewelry, but tarnished sterling silver jewelry must not be soaked in the same jar or bowl as gold jewelry. If tarnished sterling silver jewelry is cleaned in any solution with ammonia, the used solution should NEVER be used to clean gold. If you do not follow these directions, the gold jewelry will become silver plated. You will have to bring it to a jeweler to remove the silver plating.

Beyond Entertainment: A Response To NBC Dateline Report

August 15th, 2005

As a lifelong member of the jewelry trade I was pleased to see Dateline do an expose’ on the jewelry trade even though a story like this can hurt my business. It hurts the honest as well as the the dishonest because when a couple is trying to decide whether to buy a diamond or go on a cruise for their 10th anniversary, they may conclude,”I don’t know if I’m getting a good deal on the diamond but I do know when I’m having a good time. Let’s go on the cruise”. Personally, I have refused to participate in the practice of using inflated appraisal prices and overgraded certificates to decieve the customer, but I have had many suppliers request that I use these tactics. Some have even asked me to use the International Gemological Institute(IGI) reports sited on the TV expose’. I thought Cap Beesley’s (who is highly regarded in the trade) comments in the article concerning the accepted tolerances within the trade due to the subjective nature of diamond grading, although true, missed the mark. If virtually all of the diamonds are over graded then the issue is no longer inherent subjectivity or tolerances. The isssue is INTEGRITY! Industry leaders, I fear, are reluctant to come out with the whole truth as it may hurt the whole jewelry industry, which will ultimately affect their personal livelihood. In the industry it is widely understood that there are numerous certifiers and appraisers that will supply over grading and high evaluations and we know who they are. IGI is notorious for exactly the kind of deception Dateline uncovered. These deceptive marketing ploys are widely used by big box stores and large chain jewelers. J.C.Penny was convicted of using deceptive pricing and also of using deceptive statements in disclosing fracture filled diamonds. They were fined a substantial amount of money as a consequence. Have the mass merchants responded by straightening up their act or do they consider the fines just the cost of doing business? Are independent jewelers immune from this scourge? Not entirely because they have lost so many sales where a 30% to 50% discount from a big box store is still higher than their regular price. Some will conclude if you can’t beat them, join them. So, can an average consumer protect him/herself ? Yes! 1) If it seems to good to be true, it is. 2)The consumer should become as educated in the four C’s as they can. You should never give a sales pitch more weight than what your eyes and gut feeling tells you. I would never buy a diamond from a piece of paper. I have to see the diamond. This is true for the consumer as well. 3) The independent jeweler has self intrest constraining his/her behavior that the mass merchants do not share. The independent jeweler will personally confront or interact with his customers on a daily basis, at the store, in church, and in his neighborhood year in and year out whereas the staff in a big box jewelry department rarely stays the same from one year to the next. Also, if an independent jeweler where convicted of the same crimes as J.C.Penny they would likely be put out of business. 4) If the consumer wants a certificate they can trust, they should limit themselves to AGS and GIA. I am not suggesting that these are the only honorable certifiers, but these two are widely available and should be used by virtually all jewelry stores. If a merchant has no AGS or GIA certified diamonds available, the red flags should go up. They may be using the very marketing strategies exposed by Dateline.

Dateline Hidden Camera Investigation About Diamonds

August 12th, 2005

I was watching TV and saw this investigative report about appraisals and diamond grading. It wasn’t news to us, but I’m sure folks outside the jewelry industry don’t know how appraisals and diamond grading certificates can vary quite a bit depending on who provides them. That is why you should do business with a jeweler you trust. The article is an interesting read. Below is a small excerpt. “It’s just a polished lump of carbon, but really a diamond is so much more. It’s often the most precious and meaningful piece of jewelry people buy. Last year, Americans spent an estimated $30 billion on diamonds. But how can people be sure of what they’re getting for their money? Is there such a thing as “a deal” when it comes to diamonds? A “Dateline” hidden camera investigation uncovered secrets about how diamonds are evaluated and sold….” Read the entire article here.
