5.33 Ct. Purple Amethyst from Ceylon (Sri Lanka)

This listing presents a single, transparent purple amethyst weighing 5.33 carat, cut in a classic emerald cut shape, with precise dimensions of 13.48 x 9.77 x 5.85 mm, originating from Ceylon Sri Lanka, and offered by The Natural Gemstone Company. The crystal is an unenhanced natural quartz, the color described as intense in overall intensity, with a clarity grade of eye clean when examined at normal viewing distance. The specimen displays an excellent polish across all facet junctions, and the overall presentation is free of surface-reaching fractures or indications of treatment. As a quartz family gem with a Mohs hardness of 7.0, this amethyst combines wearable durability with a scale of color saturation that is seldom encountered at this scale, making this particular piece notable among collector grade and fine jewelry grade amethysts.

The cutting geometry is a textbook emerald cut, employing broad step facets on the crown and pavilion to produce linear flashes and a gallery of parallel reflections rather than faceted scintillation. The rectangular outline has truncated corners, and the large, flat table affords an unobstructed view into the body of the stone, facilitating direct assessment of color distribution and internal clarity. The depth measures 5.85 mm, which corresponds to an approximate depth to average dimension ratio of about 50.3 percent when calculated against the mean of the length and width. This depth ratio falls within the ideal range for emerald cuts, preserving a strong face up color while avoiding excessive windowing or deadness. The facet symmetry and alignment are consistent with precision lapidary work, and the excellent polish contributes to crisp facet planes, low surface haze, and optimal light transmission.

Chromatically the amethyst reads as a pure violet to purple hue with high saturation and a medium to slightly deep tone, resulting in an intense visual presence without becoming overly dark. The color is evenly distributed across the pavilion and crown, with only minimal zoning observable under directed light, which is typical for natural growth features in Ceylon material. Importantly this stone is unheated and unenhanced, so the strong violet saturation is naturally occurring, a condition that increases rarity and desirability relative to heat treated or irradiated material. In comparative terms, finding a vivid, eye clean amethyst at 5.33 carat and in this gemological class is uncommon, especially from a provenance such as Ceylon Sri Lanka, which is more frequently associated with smaller, finely colored pieces rather than larger, intensely saturated examples.

For design and setting considerations this amethyst is well suited to a variety of fine jewelry applications, including single stone rings, statement pendants, and bespoke cocktail pieces. The step cut favors settings that protect the corners and allow the large table to present the core color, therefore classic bezel and four prong mounts designed with corner protection are recommended. For pairing with other gem types, this amethyst contrasts beautifully with a White Opal as a companion stone, the opal type White Opal providing a luminous, diffused play against the amethysts intense saturation. At The Natural Gemstone Company we prepare each stone with full photographic documentation, detailed measurements, and optional certification for clients who require independent verification. Custom setting services and recommendations for complementary stones are available upon request, ensuring the gem is presented to its best advantage in any finished piece.
