2.18 Ct. Greenish Brown Cabochon Cat’s Eye Kornerupine from Ceylon (Sri Lanka)

When you are searching for a stone that answers both the heart and the conscience, this translucent 2.18 carat oval greenish brown kornerupine from Ceylon Sri Lanka stands as a clear solution. Its dimensions of 7.15 x 8.12 x 4.55 mm are ideal for a refined engagement ring or a striking collector piece, and the cabochon cutting style showcases the stone in a way that faceted gems cannot match. Evaluated at eye level, the clarity is very very slightly included, which means the gem reads clean to the gaze, while a medium color intensity gives it adaptability across warm and cool metal choices. The polish is excellent, the surface reflects light with a smooth satiny finish, and there are no enhancements applied to the stone, which preserves its natural character and long term stability. At The Natural Gemstone Company we present this kornerupine as more than a pretty gem, we offer it as the conclusion to a careful search for an ethically sourced and visually rare treasure.

Ethical sourcing matters, and this kornerupine is sourced and traced with that value front and center. The origin from Ceylon Sri Lanka is fully disclosed, and our sourcing partners adhere to responsible practices that respect the environment and the communities where the stone was found. That means mining operations that aim to minimize landscape disturbance and that invest in fair labor practices and local development, rather than anonymous supply chains that obscure origin and impact. For conscious consumers who want their jewelry to reflect their values, a gem with documented provenance and no undisclosed treatments is essential, and this piece arrives to you with that transparency. Choosing this kornerupine supports a mindful approach to collecting and gifting, where aesthetic beauty is paired with an ethical story.

One of the most compelling features of this cabochon kornerupine is its chatoyancy, the cat s eye effect that creates a sharp visible band of light sweeping across the curved surface as the stone is moved. The cabochon cut is the deliberate choice to reveal and intensify this phenomenon, because the rounded dome allows the narrow band of reflected light to glide smoothly and dramatically. Chatoyancy arises from aligned needle like inclusions or fibrous structures within the stone that reflect light in a linear fashion, and in this example the translucent body and medium color intensity make the band appear luminous and distinct. When set in a ring the band will travel across the crown, giving a living quality to the gem, and when combined with a White Opal mounted as an accent the contrast between the kornerupine s cat s eye and the opal s play of color can create a memorable and elegant duet. Collectors will prize the rarity of a strong chatoyancy in kornerupine, while couples seeking an engagement ring will appreciate the moving line of light as a subtle symbol of partnership and motion.

This kornerupine from The Natural Gemstone Company suits the buyer who wants beauty, rarity, and responsible provenance all in one. It is ideal for use in an heirloom ring or pendant, especially where the cabochon form and cat s eye show will be appreciated on a daily basis, and the medium color tone adapts well to yellow gold, rose gold, or platinum settings. Care is straightforward, because the stone is untreated, clean it gently with warm water, mild soap, and a soft brush, avoid harsh chemicals and prolonged exposure to extreme heat, and store it separately from harder gems to prevent surface abrasion. If you are building a conscious collection or designing an engagement piece that must carry meaning beyond aesthetics, this 2.18 carat oval kornerupine, ethically sourced from Ceylon Sri Lanka, answers that call.
