The Guide Contains Record Changes

The winter issue of Gemworld International’s The Guide is reporting record changes in colored gemstone prices.

“Prices for many gems are rising due to many economic and political influences,” writes Stuart Robertson, research director. “In all the years of publishing this reference source, this issue has more changes than we have ever seen before. Interesting trends are developing for the majors, including ruby, sapphire, and tanzanite. Heated rubies with glass residue are so prevalent in the marketplace today that we have redefined how we report rubies and origin to better reflect the market.”
