If you've sourced gemstones through overseas wholesalers, you already know the experience — photos that don't match reality, no recourse when something's wrong, minimums that don't work for your scale. This is the trade case for working with a local gem dealer instead: custom cuts, no minimums, full-spectrum sourcing, and what the overseas market isn't telling you.

Tourmaline is the most color-diverse gemstone family in the market — from the electric neon blues of Paraíba to the deep greens of chrome, raspberry reds of rubellite, and beyond. For jewelers and designers expanding their colored stone offering, this is the complete trade reference: every major variety, what distinguishes it, and what to know when sourcing.
