Michigan Chapter: Colored Stone Market and Price Trend Forecast for 2018

The Tucson Gem Show reveals one thing for certain, and that is the most popular colored gems for many jewelers are no longer ruby or blue sapphire. It’s important to know what’s selling and what’s not. This presentation will discuss the major issues that are currently affecting supply, demand and pricing trends for the top ten colored stones in the U.S. market. Cigdem Lule and Stuart Robertson will also explore some of the biggest developments—from rejection of memo by suppliers to inclusion of market driven color terms on lab reports—shaping the market today.

Robertson is vice president of Gemworld International, Inc. He is also research director for the company’s gemstone pricing products. Stuart is an award-winning appraiser and gemologist.
