Scientific Computing    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The song says that "diamonds are a girl's best friend," but scientists are finding that diamonds are a researcher's best friend, too. Many of the properties of diamonds necessary for technology are affected by defects and impurities present in the lattice. In collaboration with the Smithsonian Institution Museum of Natural History, the Naval Research Laboratory recently has begun studying unique and historic natural-colored diamonds to understand and characterize the defects and impurities that cause the color.

Spinel -- A misunderstood jewel
The Daily Jewel    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A completely misunderstood gem, spinel was thought to be ruby in ancient days, and Boomers tend to remember it as a synthetic stone for class rings. In today's terms, we need to work on this stone's "brand." Spinel is found in many locales worldwide -- and in some of the most exotic, gem-rich countries. Today, because of a new find in Tanzania, this rich and beautiful jewel finally is taking its place beside the finest of gems and doing it with its real name intact. More

InsideLux    Share    Share on FacebookTwitterShare on LinkedinE-mail article
This Ladyhawke Tourbillion timepiece is the brainchild of Boucheron and Girard-Perregaux, who joined forces in 2007.

Quartz is the most plentiful substance on earth. You may have a microscopic speck of it in your eye right now. That's what that itch is. But it also grows in massive crystals that weigh tons.

Jewelry Insider    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Let's face it. In the hierarchy of jewelry metals, we can all agree there's silver, there's gold, but there's really no topping platinum in terms of quality, right? According to the Platinum Guild, it's the most pure of all the precious metals: 95 percent pure, compared to 18K (75 percent) and 14K (58.5 percent) gold. And its 30 times more rare than gold. Fancy that. More

The blue stone in the auction is the first diamond to come up for sale since going into private collection. More
