Booth L99 on Level 1 of the Bayside Lobby of Mandalay Bay Resort

GIA iD100

This new instrument distinguishes natural diamonds—mounted and loose, rough and cut—from synthetic (HPHT and CVD) diamonds and diamond simulants in the colorless to near-colorless range, in sizes starting from 0.9 millimeters in diameter.

GIA UV Lamp and Viewing Cabinet – Preview

UV lamp output variation can significantly affect fluorescence color and intensity observed in diamond. This prototype device utilizes a very stable, narrowband UV LED (365 nm) whose output will not fluctuate over time compared to traditional mercury-based UV lamps.

GIA Polariscope – Preview

The GIA Polariscope is used to test the optical properties of gemstones and determine whether a stone is singly refractive, doubly refractive or is an aggregate. Doubly refractive stones may be divided further as to whether they are uniaxial or biaxial. Diamond cutters use the polariscope to determine the strain characteristics of diamonds.

When There’s No Succession Plan, Call Wilkerson

Bob Wesley, owner of Robert C. Wesley Jewelers in Scottsdale, Ariz., was a third-generation jeweler. When it was time to enjoy life on the other side of the counter, he weighed his options. His lease was nearing renewal time and with no succession plan, he decided it was time to call Wilkerson. There was plenty of inventory to sell and at first, says Wesley, he thought he might try to manage a sale himself. But he’s glad he didn’t. “There’s no way I could have done this as well as Wilkerson,” he says. Wilkerson took responsibility for the entire event, with every detail — from advertising to accounting — done, dusted and managed by the Wilkerson team. “It’s the complete package,” he says of the Wilkerson method of helping jewelers to easily go on to the next phase of their lives. “There’s no way any retailer can duplicate what they’ve done.”
