7.66 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This 7.66 carat, transparent purple amethyst presents an exemplary emerald cut, with precise dimensions of 13.42 by 9.74 by 8.32 millimeters, vivid color intensity, and an evaluated clarity grade of very very slightly included at eye level. The cutting style is a classic step cut, characterized by broad parallel facets on the crown and pavilion that establish long, linear light paths, truncated corners that provide an octagonal outline, and a generous table that emphasizes color saturation over scintillation. The polish is excellent, achieving smooth facet junctions and minimal surface abrasion, which allows for crisp facet reflections and a clean visual window from the table through to the pavilion. The piece is untreated, no enhancement, and of natural origin, sourced from Ceylon, Sri Lanka, which is known for yielding amethysts with pure violet tones and stable saturation. The facet geometry has been executed to prioritize even color distribution across the table, while the step facets create controlled flashes that accentuate the gem's vivid purple without introducing excessive brilliance that could dilute the perceived hue.

On a technical level, the emerald cut employed here optimizes depth and crown height to balance color and light return, the broad step facets producing a hall of mirrors effect that amplifies the stone's hue and reveals subtle internal character. The very very slightly included clarity grade indicates only minor, localized inclusions that do not interfere with transparency when viewed unaided, therefore the optical pathway remains uninterrupted for effective light transmission. As a variety of quartz, amethyst registers at seven on the Mohs scale, which places it below corundum and diamond, which register at nine and ten respectively, and below topaz at eight. This hardness comparison implies that while the gemstone is sufficiently durable for most jewelry applications, it is more susceptible to abrasion and surface wear than higher hardness gems, and it benefits from protective settings for everyday wear. For ring applications, we recommend bezel, channel, or protective claw settings that shield the girdle and corners, especially given the step cut corners which can otherwise be vulnerable to impacts. Routine care should include avoiding ultrasonic cleaning if inclusions are a concern, using warm soapy water and a soft brush for safe cleaning, and removing the piece during activities that risk hard knocks or exposure to harsh chemicals.

From a craftsmanship perspective, the symmetry and facet alignment of this amethyst demonstrate careful preforming and controlled polishing, the pavilion angles calibrated to reduce windowing and the crown facets cut to present the optimum balance between hue saturation and light return. The result is a gem that reads as a vivid violet in daylight and retains depth under artificial illumination, with minimal color zoning thanks to thoughtful orientation of the rough during cutting. For connoisseurs who appreciate facet architecture, the emerald cut here showcases proportional step width, even terrace spacing, and well defined facet edges, qualities that speak to a high level of lapidary skill. The piece pairs elegantly with other natural materials, and for clients interested in combined gemstone creations, we can provide matching White Opal details, White Opal being a play of light opal type characterized by a translucent to opaque base with delicate play of color, typically exhibiting pastel flashes across a light ground, a distinctly different optical response to the transparent, saturated amethyst. Combining a vivid amethyst with White Opal elements offers a contrast between the centralized color intensity of a step cut stone and the diffuse, iridescent shimmer of opal, requiring consideration of setting design to manage differences in hardness and wearability.
