21.82 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This pear shape amethyst weighs 21.82 carats and measures 24.42 mm by 16.40 mm by 9.92 mm, presenting a classic pear silhouette with a length to width ratio of approximately 1.49. The cutting style is faceted with a mixed brilliant configuration, combining a full brilliant crown with a modified pavilion geometry to optimize both scintillation and light return. Clarity is graded as very very slightly included when evaluated at eye level, indicating inclusions that are minimal and dispersed, not affecting transparency or overall visual appeal for most mounting orientations. Color intensity is vivid, with a saturated purple saturation and balanced tone that is characteristic of high quality Ceylon origin material, and the polish is excellent, producing crisp facet junctions and strong surface luster. There has been no enhancement, the material is natural, and origin is Ceylon Sri Lanka, a source known for stable violet hues and good crystal quality.

Optical performance benefits from the mixed brilliant faceting, which in this instance has been executed to emphasize a vibrant center flash and a lively perimeter scintillation. The crown facet set is tuned to capture and disperse light into multiple small flashes, while the pavilion facets are proportioned to return a significant portion of incident light through the table. The result is a stone that reads as highly transparent to the eye, with internal contrast patterns that enhance perceived depth. The stone’s dimensions and depth profile yield a depth to width ratio of approximately 60.5 percent and a depth to length ratio of approximately 40.6 percent, proportions that favor strong face up presence without excessive bulk when set. As with most amethysts the refractive index falls within the typical range for quartz, and pleochroic effects are subtle, so orientation in a mounting influences the perceived balance between bluish violet and slightly warmer violet tones.

Customization for jewelry settings is straightforward because of the stone’s combination of size, shape, and optical behavior. For rings the pear shape works well as a vertical drop solitaire with a V prong protecting the point, or as a north south orientation for a contemporary east west look that elongates the finger. A six prong configuration with a reinforced point guard is recommended for daily wear, while a low bezel or half bezel offers the best protection if the piece will be worn frequently. For pendants the length is ideal for a simple drop on a French bail that allows rotation and light intake from the pavilion, or as the centerpiece of a halo setting where a line of small brilliant cut diamonds or colored sapphires can enhance the vivid purple and add contrast. For earrings a single large stone can be used as a focal drop, or the piece can be the anchor for a cluster or chandelier design with calibrated accent stones. For brooches and cufflinks the stone’s depth supports secure bezel seats and custom galleries that allow light to enter the pavilion for maximum brilliance.

Technical considerations for fabrication include securing the pointed end and accommodating the pear shoulders without stress concentration. Because the girdle appears even and the polish excellent, minimal reworking is necessary, however if a client prefers a specific pavilion break or length adjustment the stone can be sympathetically re-polished, noting that every rework will reduce carat weight. Metal choice influences perceived color, with 18 karat yellow gold warming the violet, rose gold softening and accentuating red undertones, and platinum or white gold creating a cool contrast that emphasizes saturation. Gallery and head design should incorporate light wells or openwork to preserve the mixed brilliant return, and the setting floor can be adjusted to maintain ideal crown height for face up brightness. The Natural Gemstone Company can advise on prong styles, bezel lip tolerances, and gallery clearance, and we offer bespoke mounting services that respect the stone’s proportions, secure its fragile tip, and highlight its vivid Ceylon color while balancing daily wearability and aesthetic intent.
