21.33 Ct. Amethyst from Bolivia

This attractive Bolivian amethyst from The Natural Gemstone Company is a transparent, fancy shaped stone weighing 21.33 carats, with finished dimensions of 18.32 by 18.29 by 12.20 mm, presented in a mixed brilliant cut. The gem exhibits a medium intense purple hue with very good saturation, and the color is distributed with pleasing uniformity across the crown and pavilion, creating consistent face up presence. Clarity is graded very very slightly included, evaluated at eye level, which in practical terms means the stone is clean to the unaided eye under normal viewing conditions, with only minute internal characteristics detectable under magnification. There has been no enhancement applied to this piece, which preserves the natural tonal qualities and crystallographic character typical of Bolivian amethysts, and the polish is graded excellent, producing crisp facet junctions and high contrast at facet edges.

From a cutting and optical performance perspective the mixed brilliant cut used on this amethyst marries a faceted brilliant style crown with a modified pavilion geometry to maximize light return and lively scintillation. The crown displays a series of star and kite facets that interact with a moderately sized table to produce a central star flash when viewed face up, while the pavilion facets are configured to balance return and dispersion, generating appealing contrast between deep purple flashes and lighter violet reflections. Faceting symmetry is precise, with well aligned facet planes and consistent facet proportions that contribute to even extinction patterns and predictable scintillation as the stone moves. The girdle presents as well finished and proportioned to accommodate standard mounting techniques, and the pavilion depth has been controlled to avoid excessive windowing or darkening, ensuring that the medium intense color retains depth without appearing overly saturated. The excellent polish enhances the stone surface, permitting clean light transmission and maximizing brilliance, while the lack of enhancement guarantees that the observed color and optical behavior are intrinsic to the crystal itself.

This 21.33 carat specimen will make a striking and memorable gift for someone who appreciates the technical qualities of fine gems, and it is especially suited to a statement pendant or a bespoke cocktail ring where the mixed brilliant faceting can be admired from multiple angles. The substantial carat weight and generous dimensions allow craftsmen to design secure settings that showcase the central table and crown star pattern, while the even medium intense color offers versatility with both warm and cool metal choices, including yellow gold for strong contrast and white gold or platinum to emphasize the purple tones. For the connoisseur who values unenhanced material, the Bolivian origin adds provenance and character, and the very very slightly included clarity grade ensures that the stone reads as visually clean when worn, yet retains the natural identity appreciated by collectors. At The Natural Gemstone Company we take care to present stones with detailed grading notes and consistent photographic references, and this amethyst is offered ready for immediate incorporation into a design, or as a premium inventory addition for jewelers and private buyers seeking a technically refined, eye catching gift that will command attention and admiration.
