ASA Princeton - May 15, 2017 - Variables that Affect Value in Gems

  • Main Street Bistro 301 North Harrison Street Princeton, NJ, 08540 United States (map)

Please join us at 6pm on Monday, May 15, 2017 at Main Street Bistro in Princeton as Daniel W. Campbell BS, GG, FGA of Hamilton Jewelers presents:

Variables that Affect Value in Gems

Gem identification is an extremely important component of jewelry analysis and appraisal. The value of an item of jewelry can be dependent almost entirely on the identity of the gem or gems present.  The question, however, is not simply, “Is the gem a ruby, emerald or sapphire?” for example.  There are many gems of every color, which vary in quality, name recognition, desirability, rarity, supply and demand, size, country of origin, durability and many other factors.  Many of these gems have laboratory grown counterparts or can be treated in a variety of ways to alter or improve their appearance.  Some are even glued or fused together to make them look like a valuable gem.  In this presentation, we will review a select few gems, what materials may be used in their place and the widely varying values that may be assigned to them.
