Vintage 5.45 Carat Watermelon Tourmaline and Diamond 18K White Gold Ring

About the Item

Vintage 5.45 carat Watermelon Tourmaline and Diamond Ring in 18 Karat White Gold Ring. A Natural 5.40ct Pink and Green "Watermelon" Tourmaline, emerald cut and measuring 16.5 x 7.85X5.25mm. Crafted in 18 carat White Gold (tested carefully) and containing Eighteen Round Brilliant Diamonds totalling 0.75ct total weight. Total weight: 15.37 gr. Measurements: Width 20 X Length Ring Size: 54 mm (US 7) Watermelon tourmaline is pink in the center and green around the outside. Crystals of this material are typically cut in slices to display this special arrangement. To be a true “watermelon,” this crystal should have a pink or red core with a green rind. The pink or red center of these crystals forms first. Then, a shift in chemistry in the geothermal fluid that creates the crystal occurs. Instead of manganese, which causes the pink color, iron enters the solution, which imparts a green hue to the crystal. Dark to light green outer ring and pinkish to red core, separated with a light pink or white color, it resembles the fruit of the same name. The watermelon tourmaline is a relatively durable stone for jewelry pieces while its eye-catching and distinctive colors. We offer FREE insured international shipping with FedEx International Priority and Ferrari Express, we also guarantee the accuracy of our descriptions and the authenticity of every item we sell.
