12.59 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This 12.59 carat oval amethyst from Ceylon Sri Lanka presents a textbook example of precision cutting and natural character, offered by The Natural Gemstone Company. The gem measures 15.84 by 13.04 by 9.35 mm, yielding a depth of approximately 64.8 percent, a proportion that supports strong light performance while retaining substantial weight for statement jewelry. The cutting style is faceted with a mixed brilliant cut, featuring a brilliant style crown which disperses light into lively scintillation, and a modified step pavilion that deepens color saturation and preserves carat yield. The overall symmetry and excellent polish result in crisp facet junctions and consistent return of light across the oval outline, minimizing windowing and maximizing perceived size.

Color is a vivid intensity of true violet to rich purple, evenly distributed through the stone, and enhanced by the mixed cutting geometry which balances brilliance and color. Clarity is graded eye clean at normal viewing distances, yet under magnification this amethyst displays minute internal features that serve as natural identity markers. These include sparse microscopic mineral crystal inclusions and very fine healed feather patterns, together with occasional fluid related remnants, each acting as a fingerprint that confirms the gem as untreated and natural. There is no enhancement, no heat treatment or irradiation, and surface condition is excellent with a smooth polished girdle. Practical considerations for setting include the stone dimensions which are ideal for a bold solitaire ring or a substantial pendant, and the depth and pavilion design which favor bezel or secure claw settings that protect the girdle while allowing the crown to display maximum fire. For collectors and connoisseurs who value both optical performance and natural origin, this Ceylon amethyst embodies transparent clarity, vivid color, and artisanal cutting, making it a refined addition to a curated collection from The Natural Gemstone Company.
