Blue-Green Tourmaline and Blue Diamond Torus

Another fabulous gemstone from the Jewelry Expert collection that merits a special jewel is this oval torus ring. The main gem is a stunning blue-green Tourmaline from Afghanistan, cut with negative facets in the pavilion so as to create a dazzling array of brilliance and sparkle. The centerpiece is a natural grayish blue-violet diamond that we bezel set in platinum.

The 8.40 cts oval natural Blue-Green Tourmaline Torus measures 16.9 x 11.9 millimeters; the blue-violet diamond measures 2.15 mm and weighs 0.038 carat. I chose this blue-violet diamond for the center because of it's soft periwinkle color that was a wonderful complement to the verdant hue of the tourmaline.

A special gemstone such as this really deserves an equally special design. Since this is a larger stone, I believe it would work best as a pendant or necklace.

Some time ago I designed a striking necklace for a client in Japan, featuring a round amethyst torus ring and demantoid garnet. My Star Gazer design would be a great option for the oval blue-green tourmaline torus, with some modifications such as an attenuated or more elongated frame.

I was also thinking that instead of a concave diamond shape, perhaps a double outer rim that was also oval shaped and followed the classic outline of the tourmaline with a small round diamond channel set within the outer rim at the north, south, east and west positions. I can also see channel setting a complete line of small round brilliant diamonds forming a series of concentric ovals with the metal work, the diamonds and the torus.

Instead of setting the oval torus tourmaline vertically, it could be oriented horizontally with the pendant designed more as a slide necklace rather than a pendant drop. In this concept, the tourmaline could be set within an oval or cushion shaped yellow gold frame with small trapezoid, bullet or triangular shaped platinum tabs at the four corners, set with small colorless diamonds. The side walls of the frame could either be open and embellished with platinum scrolls or the walls could be solid and hand engraved with a radiating pattern of spikes and lines to create a star-burst effect.

And that leads to another design idea...... and another and yet another.

Sometimes I start with a design idea in my head that takes me on a journey to locate the perfect stone for the creation. But other times, I start first with the selection of a beautiful gemstone that captures my interest and dictates the design.

I must admit that I truly have a passion for exceptional gemstones and these wonders of nature inspire me to design and create jewelry that captivates and intrigues.

That's why I really love my job. So many wonderful ways to feature beautiful gems and create extraordinary jewels that will become a favorite heirloom for generations to come.

Torus rings are also available in round, marquise, pear and sometimes cushion or rectangular shapes. However, most are cut in the round and oval shapes. The talented lapidarist that cuts these stunning beauties often works with blue sapphire, montana sapphire, fancy colored sapphire (violet, pink, yellow and bi-color) as well as tourmaline, aquamarine, tanzanite and amethyst.

If you would like to purchase this fabulous blue-green tourmaline oval torus, please send me an email. I am also happy to discuss possible design options with you for this gorgeous gem.
