1.83 Ct. Purple Cabochon Amethyst from Ceylon (Sri Lanka)

This listing describes a single translucent amethyst specimen, presented in a traditional cabochon finish to emphasize its internal depth and color. The gem weighs 1.83 carats, and measures 7.87 x 8.06 x 4.18 mm, yielding a balanced round profile with a gentle dome. The cutting style is cabochon, which preserves transparency while producing a smooth, continuous surface. The polish is excellent, resulting in bright, consistent reflections across the dome. Clarity has been graded as slightly included when evaluated at eye level, meaning minor internal features are present but they do not materially detract from the overall appearance or light transmission. The piece is free of any applied enhancements, and its provenance is Ceylon Sri Lanka, a region recognized for producing high quality quartz family gems.

Color is a principal attribute of this amethyst, and this specimen exhibits an intense purple saturation that appears evenly distributed when viewed face up. The tone is deep enough to convey a rich violet character, yet remains sufficiently transparent to allow light to travel through the cabochon and create lively internal color play. The cabochon format softens the appearance of any internal features, while the uniformity of hue across the dome contributes to a stable visual impression in both direct and diffused lighting. Surface reflections are clean due to the excellent polish, and the round outline offers predictable symmetry for use in a variety of mounting styles. Overall, the color intensity and transparency combine to produce a gem that reads as vibrant without appearing overly dark.

The absence of enhancements is notable, and it speaks to the natural quality of the material. No heat treatment, irradiation, dyeing, or filling has been applied to alter color, clarity, or stability, and the origin of Ceylon Sri Lanka further supports the natural character of this amethyst. From a gemological perspective, untreated stones maintain their intrinsic value and are preferred by collectors and those seeking natural material for bespoke jewelry. The slight inclusions observed at eye level are natural internal features consistent with quartz group crystals, and they serve as identifiers of authenticity rather than detractors. The cabochon cut was chosen to present the stone in a classical, understated manner, ideal for pieces that emphasize color and smooth form rather than faceted brilliance.

Durability should be considered when planning for setting and wear, and on the Mohs hardness scale this amethyst rates approximately 7. This places it within a range that is harder than most common minerals such as apatite and fluorite, and similar to other quartz varieties, while remaining softer than corundum and diamond. For practical comparison, diamond is rated 10 on the Mohs scale, corundum including sapphire and ruby is rated 9, topaz is typically rated 8, and glass or many silicates are below 7. The rating of 7 means the stone is resistant to everyday scratches from materials softer than it, but it can be scratched by harder substances, and it should be protected from rough impacts. Care recommendations include avoiding contact with abrasive surfaces, removing jewelry during heavy manual work, avoiding sudden thermal shocks, and refraining from aggressive ultrasonic cleaning if the mounting or inclusions could render the stone vulnerable. Routine cleaning with mild soap and warm water, followed by gentle drying with a soft cloth, will preserve surface polish and optical qualities.

This amethyst cabochon is presented by The Natural Gemstone Company, and it is suitable for a range of jewelry applications where color and a smooth dome are desired. The round cabochon shape adapts well to bezel settings, cabochon mounts, and custom hand settings that emphasize a secure edge while showcasing the dome. Given its dimensions and weight, it can serve as a focal solitaire in a ring, a pendant centerpiece, or an accent in a bracelet or brooch, with the caveat that ring settings intended for daily wear should incorporate protective design elements. The slightly included clarity and intense color suit classic and contemporary designs alike, and the natural, untreated origin will appeal to clients seeking authentic material.
