Fine Emeralds from Colombia and Zambia
The Emerald is truly coming into its own as this year’s spring season bursts forth. On the rise for several seasons, emerald green is fashion’s Color of the Year for 2013.

Padparadscha in Custom Rose & White Gold Engagement Ring
We’ve always loved the ultra rare variety of fancy sapphire known as the Padparadscha. Early in my career, working in the gem indentification labs of GIA, I had the opportunity to see a few good examples of the natural Padparadscha Sapphire and to learn the subtle distinctions that make this gem so desirable. Our informational blogs about this exotic beauty have become so well received that clients seek us out as experts to help them find the perfect “Pad”– and we love doing it!

We just delivered this beautiful 14K gold ring to a delighted customer. A new client, she had seen one of our custom ring samples over the Christmas holidays and had an idea– she loved cameos and had a particular affinity for the Three Graces of Greek and Roman mythology, the goddesses of beauty, creativity, and nature. Rather than something set with the typical cameo carved from shell or stone, she wanted an all metal ring of sterling silver. Read the rest of this entry »

We’ve recently added several interesting vintage pieces to our Estate Department. This cameo was a real sleeper– it was literally so crusted over with years of accumulated crud (gemological term!) that we barely recognized it. Read the rest of this entry »
