Stone Details — Blue-Purple Tourmaline, Sapphire & Natural Diamonds

Tourmaline ranks 7 to 7.5 on the Mohs hardness scale, making it suitable for rings worn with reasonable care. The blue-purple hues in this stone place it in the rare indicolite-to-violet range of the tourmaline color spectrum — among the most collectible and visually striking varieties. The 0.72 carats of sapphire accents complement the cool tones of the center stone beautifully, while 0.20 carats of natural diamonds in G/H color and VS clarity add flashes of white brilliance that contrast against the deep, saturated tourmaline and sapphire color.

The Setting — 14kt Yellow Gold

Yellow gold is a historically classic pairing for deeply colored gemstones. The warm tone of 14kt yellow gold (585 purity) creates a rich contrast against the cool blue and violet of the bi-color tourmaline and sapphire accents, allowing the gemstone colors to dominate the visual composition. This is a cocktail ring designed to be noticed — a statement piece for those who love rare, museum-quality gemstones in wearable form.

What Is Bi-Color Tourmaline?

Bi-color tourmaline is one of nature's most extraordinary phenomena — a single gemstone that displays two distinct colors within the same crystal, created by shifting trace elements during its formation deep in the earth. This ring showcases a 1.50 carat blue-purple bi-color tourmaline, where rich inky blue transitions into deep violet within a single stone. No two bi-color tourmalines are alike, making every ring cut from this material genuinely one of a kind.
