22.47 Ct. Amethyst from Ceylon (Sri Lanka)

This listing describes one transparent purple amethyst weighing 22.47 carats, presented in an oval shape with precise dimensions of 20.65 x 17.53 x 10.09 mm. The stone has been fashioned with a mixed brilliant cut, combining step cut pavilion facets with a faceted crown to optimize light return and scintillation. Clarity is graded as eye clean when examined at normal viewing distance, indicating an absence of visible inclusions that could interrupt the visual plane. Color is assessed as intense, a deep and uniform purple that benefits from the generous table and well proportioned crown. Polish is excellent, yielding crisp facet junctions and smooth reflective surfaces. There has been no enhancement to this specimen, and its documented origin is Ceylon, Sri Lanka. For reference within matched commissions, the opal type commonly considered for complementing this amethyst is White Opal.

The scale and oval geometry of this 22.47 carat amethyst make it particularly well suited to custom jewelry projects that emphasize a single bold center stone. The 20.65 mm length and 17.53 mm width provide a substantial visual presence for a solitaire ring, statement pendant, or sculpted brooch, while the 10.09 mm depth supports secure bezel or prong settings without compromising profile or comfort. The mixed brilliant cut enhances both scintillation and color saturation, allowing designers to play with open baskets or closed pavé halos to modulate how light interacts with the stone. The oval outline is versatile, accommodating traditional four or six prong mounts, east west orientations, and three stone arrangements. The eye clean clarity removes the need for heavy protective bezels for inclusion related reasons, permitting cleaner mounting lines and less metal intrusion around the girdle for contemporary aesthetics.

When planning a custom setting, consider metal choice, mounting height, and companion stones to maximize the amethysts attributes. White metals such as platinum and white gold will emphasize the amethysts violet blue undertones and create a crisp contrast with accent White Opal, whereas warm metals like yellow gold will enrich the purple toward a warmer, slightly reddish cast. The White Opal type offers a soft play of light and diffuse body color that pairs well with intense purple, and it can be incorporated as side stones, a halo, or inlay to introduce subtle iridescence without overpowering the main gem. The substantial carat weight allows for architectural settings including cathedral shoulders, open gallery work to show the pavilion, and custom engraving on shanks and bezels. For wearable comfort, consider lower profile settings for rings, and for pendants allow open work under the stone to preserve the mixed cut dynamics.

Provenance and handling notes are provided for professional use and long term care. This amethyst is natural, originating from Ceylon Sri Lanka, and has received no enhancements, which supports predictable color stability and market valuation. While amethyst is durable for daily wear in many settings, it is softer than corundum and diamond, so secure mounting and occasional professional inspection are recommended for rings and bracelets. Clean with warm soapy water and a soft brush, avoid prolonged exposure to strong acids and high heat, and store separately from harder gemstones to prevent abrasion. The Natural Gemstone Company stands behind the documented characteristics of this specimen and can assist with measurements for bespoke fittings, sourcing matching accent materials including White Opal, and providing grading documentation to support custom design and insurance.
