Large and Unusual Gems
Mehraj Uddin exhibited two large topaz of exceptional pink to red color (6.38 and 12.08 ct). As with virtually all pink topaz, he acknowledged that these fine stones were heat treated. Debuting at Noor’s GJX booth was pinkish purple copper-bearing tourmaline from Mozambique (figure 2).
For some large and exceptional gemstones, such as a 254.50 ct peridot cabochon from Pakistan, Uddin admitted they hold on to these stones for 10 or 20 years. The company is reluctant to sell them because of the difficulty in replacing such inventory. They will only sell when they feel the market is high.
