Huge Diamond Sells For Over $35 Million

Filed under: Jewelry

Last fall we speculated that a huge 507-carat piece of rough diamond might sell for $30 million. The result was even bigger than anticipated. Petra Diamonds announced that the stone sold for $35.3 million which was the highest sale price ever for a rough stone, an impressive $69,557 per carat. Hong Kong-based Chow Tai Fook Jewellery Company Ltd. bought the rock which has been given the preliminary name "Cullinan Heritage," at a tender in South Africa. The stone is the 19th largest piece of rough unearthed in history and is exceptional both in terms of size and color and clarity.

It is believed that the buyers will seek to sell the stone in China. The rough stone could yield a "D-flawless" clear polished stone of 170-180 carats, a stone which could sell at a huge price. The diamond will be doubtlessly be scrutinized by teams of expert cutters and all possible strategies will be mapped and modeled before the first cut is made, a process which generally takes several months.

Chicken Egg-Sized Diamond Could Get Over $30 Million

Filed under: Jewelry

Bloomberg calls it a chicken-egg-sized diamond but the 507.6 carat rough stone found at Petra Diamonds' Cullinan mine in South Africa in September could earn some serious scratch. The diamond was part of a haul of four large stones found at the mine in September. The other stones, including a 168-carat stone sold for $6.28 million last week, have all been sold off. The other two stones sold for a total of $2.8 million. Now BMO Capital Markets is predicting a possible price of $31 million for biggest stone. The price is just an estimate.

Petra is still considering what to do with the stone. Stones of this size aren't found too often and the company is taking its time and pursuing all angles before any potential sale. The company's goal is obviously to get the biggest price for the stone but also to help make sure that the stone's legend lives on. Unlike many small diamonds, large stones tend to carry the name of their source along with them. It's hard to say what the final carat count will be. Rough stones can lose half their carat weight in polishing. Depending on the inclusions and other flaws that the diamond cutters will have to work around this could yield several substantial cut stones which could each go on to command their own multimillion price tags as they head down the supply chain.

Diamonds For A Cure

Shop NBC host, jewelry designer and breast cancer survivor Neda Behnam has created a new company called Diamonds for a Cure (DFAC) which will join the growing number of companies raising funds for cancer research. The first two offerings capitalize on the current trend for rough diamond jewelry. A 4ct. natural pink diamond flower ring set in rose gold sells for $2,499.99 but only $100 goes to cancer research. An 18k white gold rough diamond pendant with a polished diamond center stone on either a black or pink silk cord sells for $549.93 and $50 goes to breast cancer research. The idea is admirable but compared to other jewelry lines, the amount given for charity seems a bit low.

Diamond company De Beers has put its new watch collection online. The watches continue the De Beers Talisman collection which mixes faceted and rough diamonds in a variety of whites, yellows and browns. Perhaps the flashiest watch in the line is the Talisman Suntime watch. It has an 18K gold 40mm dial set with 58 brown and white polished brilliants and one rough diamond in the center (a total of 2.35 carats). The watch uses a quartz movement and sells for $15,000. Other watches in the line are in white gold and feature various sizes of rough diamonds interspersed with faceted stones.

Rough Diamonds Becoming More Popular In Jewelry

The Wall Street Journal has an interesting piece on the recent trend in using rough diamonds in jewelry. We first checked this out earlier this year when we saw the jewelry from Diamond In The Rough, and De Beers has also used rough diamonds in their Talisman collection. The stones lack the appeal of faceted diamonds: no flashes of color, no sparkles, in fact, as the Journal says, they look downright gravel-like. The stones have a certain organic appeal and the jewelry stores like them because they are cheaper to produce and offer a chance to use stones which may not have been suitable for cutting. But one of the major caveats here is that a rough diamond isn't appraised in the same way as a cut stone and so it can be tough to know the true value of a stone. One thing that is not mentioned in the article but is a question for me is how the value of the rough diamonds will hold up over time. It seems to me that it might be hard to resell one of these once the trend fades away. I've always thought of the beauty of a diamond as being a collaboration between nature and man because it takes a skilled cutter to reveal a diamond's true beauty.

Valentine's Day is high time for diamond purchasing but your beloved might look a bit askance at first when presented with a ring like this bauble. It's a rough diamond wrapped in wrapped 18K white gold with pave diamond accents. Diamonds in the Rough sells a variety of rough diamonds accented with smaller cut and polished diamonds. The diamond shown here is an 89 carat rough which sold during the holidays for $100,000. Smaller rings in the collection are available as well as pendants secured with a spider web of pave diamonds and gold. The effect is startling, at once both ancient and completely modern. The diamonds are also certified conflict free.
