10.12 Ct. Amethyst from Ceylon (Sri Lanka)

This specimen is a single transparent purple amethyst, precisely weighed at 10.12 carats, shaped in a classic emerald cut, with dimensions measuring 15.12 by 10.72 by 8.10 millimeters, an excellent polish, and a clarity graded as very very slightly included at eye level. The color intensity is described as intense, with a rich medium to deep purple saturation that remains lively across the full table of the stone. No enhancements have been applied, and the gem is of natural origin from Ceylon, Sri Lanka, a region known for producing consistently fine quartz varieties. The emerald cut communicates a restrained elegance, using step faceting to emphasize even color distribution and the stone clarity, while providing crisp facet lines and a refined rectangular silhouette that is particularly flattering in rings and pendants.

From a gemological perspective this amethyst delivers attributes that educated buyers prioritize, namely, natural origin, unenhanced color, and a high clarity tier for its size. At 10.12 carats and with the given proportions, the step cut reduces the type of scintillation seen in brilliant cuts, and instead showcases color depth and internal clarity, making any small inclusions less distracting and more part of the gem character. Amethyst is a variety of quartz with a Mohs hardness of seven, which affords reasonable everyday wearability when set intelligently, though it benefits from protective settings for frequent use. The very very slightly included evaluation at eye level indicates the stone appears eye clean to most observers, which combined with the intense color, enhances its appeal and market value relative to similarly sized samples that exhibit heavier zoning or obvious surface reaching inclusions.

When designing a custom piece around this purple emerald cut amethyst, consider complementary stones that enhance color contrast, light performance, and overall harmony. White Opal provides a soft play of background milky white and subtle spectral flashes that can create a delicate contrast against the saturated purple. A pair of small white opal cabochons flanking the amethyst in a three stone ring, set in protective bezels, will introduce a luminous contrast while preserving the opal integrity. For a more classic approach, a halo of well matched white diamonds or near colorless melee stones will increase perceived size and add brilliance that balances the step cut elegance of the central amethyst. For color accents, consider warm yellow gold and small citrines to echo the quartz family, or cool green tsavorite garnets or peridots to produce a vibrant triadic color scheme, always taking care to match durability and setting style, since opal requires more protective mounting than quartz.

At The Natural Gemstone Company we curate pieces with attention to origin, treatment disclosure, and lapidary quality, and this amethyst reflects those priorities. For a bespoke commission we recommend discussing setting options that protect the stone edges and crown, including bezel or half bezel options for everyday rings, and prong settings that lift the stone for pendants to allow light to pass through the pavilion. If you prefer the white opal pairing, we suggest using accent opals that are designated as White Opal, with careful selection for stability and consistent tone, and placing them in lower profile settings to reduce impact risk. We can provide comparative photographs of settings, precise measurements for ring sizing and setting tolerances, and a written report detailing the weight, dimensions, clarity assessment, polish grade, enhancement disclosure, and origin to support your purchase decision. Please contact us to discuss design sketches, metal choices, and to receive a tailored recommendation that preserves the integrity and value of this outstanding Sri Lankan amethyst.
