Pure Watermelon Tourmaline Rings  

Natural Pink-Green Tourmaline in Sterling Silver Rings

Watermelon tourmaline belongs to the elbaite variety of the tourmaline mineral group. The distinctive pink-to-green gradient occurs when trace amounts of manganese and lithium shift during crystallization, creating concentric color zones visible in cross-section cuts. Most specimens originate from deposits in Brazil, Nigeria, Madagascar, and Afghanistan. On the Mohs hardness scale, tourmaline rates 7 to 7.5, making it durable enough for regular wear in ring settings. The sterling silver settings in this collection use 92.5% pure silver alloyed with copper for structural strength. This standard composition holds stones secure while maintaining the bright finish that complements tourmaline's natural color play. Cuts range from polished slices that reveal the full watermelon pattern to faceted stones that emphasize the pink or green zones. SilverRush Style sources natural tourmaline without synthetic treatments or color enhancement. What you see in each listing reflects the actual stone characteristics. Take your time browsing the full range to find the specific color distribution and ring size that fits your preference.
