Frequently Asked Questions (FAQ) / Tourmaline Cutting

Why are many tourmalines cut in long narrow bars? I don't see many other gems cut that way. Is it just the fashion now?

Tourmaline forms in long crystals with a triangular cross section and rounded sides. Since gem cutters strive to preserve as much of the rough stone as possible, you often see tourmaline cut in long bars, octagons or baguettes. Additionally, a lot of tourmaline has interesting color variations in these long crystals and these cuts also tend to preserve and showcase these unique color characteristics.
