We only buy colored stones from suppliers who are AGTA members. AGTA members are screened and must adhere to the organization. We’ve been seeing a lot of fun color lately. Mostly we work with sapphires (they come in all colors and we can source some unique colors domestically from Montana) but emeralds & tourmalines have been rising in popularity at M. Flynn. Keep in mind, some gems are better suited for daily wear. While diamonds are usually pretty straightforward because it’s one gemstone with one standard grading system, the colored gemstone market offers us so many choices, price ranges and cut options it can be fun but sometimes overwhelming to buyers. The AGTA adheres to strict standards of ethics. Stones are always fair trade and all stone enhancements must be acceptable by AGTA and disclosed to the buyer.
