Roskin Blues

Our old friend and former colleague at GIA, Gary Roskin, has published an absolutely fascinating account of a major event at the pinnacle of the gem world. Under the auspices of the Smithsonian Institute, the most famous of all gems, the Hope Diamond, was brought together for the first time with the Wittelsbach Blue, now known as the Wittelsbach-Graff diamond, for the purpose of research and comparison. Part 1 is featured in Gary’s “The Roskin Gem News Report” at this URL, Gary promises more to come in part 11. This is an outstanding read for those of you who love gems– don’t miss it!

Rare gems have quietly come back as an investment and store of wealth as the world economy totters along. The one of a kind nature of these rarest of nature’s treasures means that, just like fine art, the truly good ones that will stand the test of time are in a class by themselves. The challenge is determining which ones are truly rare! Give us a call if you’d like to know more about investment opportunities in rare gems.
