This tale of woe illustrates some of the risks and challenges we jewelers face in our fascinating business. Last year, I had seen this lovely and large reddish purple tourmaline several times. Gem dealer Jack had tried mightily to tempt me with it, an unheated stone from the country of Mozambique in East Africa, an […]

The desire and ability to exploit our environment and to utilize and improve the natural materials we find is rooted in our deepest past, and is in fact, part of the reason we are here today. I was absolutely fascinated by an article in the August 2010 Scientific American, When the Sea Saved Humanity, that […]

These two sapphires are both from the island of Sri Lanka, both are heat enhanced, both are from the same vendor, both weigh about the same. Here's another photograph, same stones, same photographer (myself), same camera, same photo stage, similar macro lens, slightly different lighting. Can you guess which one costs more?

A service we offer is finding rare gemstones. One of my “quests” at Tucson 2010 was for an unusual stone for a client who owns a stable of Tennessee Walking Horses. One of his horses is a World Grand Champion, so he was interested in a ring he could wear that would bring attention to […]
