23.57 Ct. Amethyst from Brazil

This beautiful transparent 23.57 carat oval purple amethyst measures 22.90 x 16.40 x 11.20 mm, and is masterfully fashioned with a mixed brilliant cut to maximize face up scintillation and light return. The stone has a clarity grade of very very slightly included, evaluated at eye level, which in practical terms means it reads as eye clean to most observers with only minute inclusions visible under magnification. Its vivid color intensity is pure and evenly distributed across the table, and an excellent polish brings out crisp facet junctions and lively surface brilliance. The piece is heat treated, a stable and well understood enhancement used to refine and stabilize the violet hue, and it is sourced from Brazil, a region renowned for producing large, clean amethyst crystals. Presented by The Natural Gemstone Company, this specimen offers a rare combination of size, color saturation, and lapidary precision that will satisfy collectors and makers of high quality jewelry alike.

When comparing brilliance to more common gemstones it is important to separate optical potential from absolute refractive performance. While diamonds and corundum have higher refractive indices and therefore greater internal dispersion, a well cut amethyst like this one can outperform many commonly used colored stones in practical brilliance. Compared to citrine and aquamarine it shows a noticeably richer face up presence because its vivid purple color increases contrast and perceived light return. Against commercial topaz and peridot this amethyst benefits from superior color saturation and the mixed brilliant facet arrangement, which creates a dynamic play of light and dark facets that reads as lively scintillation in hand. The combination of transparency, very very slight inclusions, high polish, and the mixed brilliant cut allows this amethyst to present bright, even flashes of light and strong color zoning control, characteristics prized by educated buyers. For the discerning purchaser this gem represents a compelling balance of aesthetic appeal and value, combining a collectible large carat weight with transparent origin disclosure and standard trade enhancement information, qualities that The Natural Gemstone Company ensures for every offering.
