20.05 Ct. Purplish Red Rubellite Tourmaline from Brazil

This 20.05 carat purplish red rubellite tourmaline from Brazil presents a rigorous combination of weight, proportions, and cutting precision, ideal for collectors and designers who prioritize technical quality. The oval outline measures 17.74 by 13.90 by 11.47 millimeters, yielding a depth percentage of approximately 72.5 percent based on the mean diameter, a proportion that contributes to pronounced color saturation and strong light return. The cutting style is faceted with a mixed brilliant schema, combining a brilliant facet arrangement on the crown to maximize scintillation, with controlled step-like facets on the pavilion to concentrate the gem s chromatic intensity, the result is an even, intense purplish red color intensity that remains lively under varied lighting. Clarity is graded slightly included at eye level, these minor inclusions are positioned and oriented so as not to impede the gem s transparency, and they add natural character without compromising visual performance. The polish is graded excellent, facet junctions are sharp and consistent, and the overall lapidary execution preserves optical symmetry while enhancing the stone s inherent color. The piece has undergone a stable heat treatment to refine tone and remove brownish overtones, a standard enhancement in rubellite production that has been applied conservatively to maintain transparency and structure.

The Natural Gemstone Company recommends this rubellite for applications ranging from elevated everyday pieces to formal statement jewellery, given its combination of size, color and cut. In a solitaire ring setting, the mixed brilliant cut will deliver lively table and crown brilliance, while a bezel or partial bezel can protect the girdle and accommodate more active wear, the gem also responds beautifully to a diamond halo which can increase perceived brightness and emphasize the purplish red hue. For metal selection, rose or yellow gold will warm the color palette, while white gold or platinum will emphasize contrast and clarity. As a tourmaline, hardness is approximately 7 to 7.5 on the Mohs scale, making routine wear feasible with sensible care, avoid ultrasonic cleaners and extreme thermal shocks to preserve the post heat treated condition. For buyers seeking technical excellence in cut, color and finishing, this Brazilian rubellite embodies the balance of lapidary craft and natural gem quality that The Natural Gemstone Company consistently offers.
