1.42 Ct. Cobalt Spinel from Ceylon (Sri Lanka)

This is a transparent 1.42 carat oval cobalt spinel from Ceylon Sri Lanka, measuring 7.61 x 6.32 x 3.89 millimeters, and presented with a mixed brilliant cut, intense color intensity, excellent polish, and an eye clean clarity grade as evaluated at eye level. The cobalt element in this spinel produces a stable, vivid blue that is often compared to fine cornflower sapphire tones, while retaining spinel specific optical properties such as strong light return and lively dispersion. Because this stone is natural with no enhancement, its color is inherent and stable, which is a key attribute for educated buyers seeking traceable origin and untreated material. Spinel's durability around 8 on the Mohs scale makes it an excellent daily wear gem, and the eye clean clarity combined with excellent polish ensures maximum brilliance and visual purity under normal viewing conditions.

For customization this cobalt spinel adapts exceptionally well to a broad range of jewelry settings, and The Natural Gemstone Company can guide you to the most appropriate design choices based on the stone proportions. The oval outline at 7.61 by 6.32 millimeters sits beautifully as a central solitaire in rings for sizes typically designed to showcase a 6 to 7 millimeter profile, and the 3.89 millimeter depth indicates a moderate pavilion that returns light well while remaining simple to seat securely. Recommended settings include four or six prong mounts to maximize table exposure, a low bezel for active wearers who prefer edge protection, an east west orientation for modern ring silhouettes, a halo with pavé diamonds to amplify visual size and sparkle, and three stone or cathedral settings for added architectural presence. This spinel also performs elegantly as a pendant, a pair of matched stud earrings, or distinctive cufflinks, and pairs attractively with platinum, 18 karat white gold, 18 karat yellow gold, or rose gold depending on desired contrast.

The Natural Gemstone Company provides personalized consultation for bespoke settings, CAD renderings on request, and assistance selecting complementary accent stones to enhance contrast and light performance. Because the gem is unenhanced, eye clean, and originates from reputable Ceylon sources, it represents a technically sound choice for collectors and connoisseurs who value provenance, workmanship, and long term wearability.
