1.62 Ct. Blue Cobalt Spinel from Vietnam

This exquisite transparent cobalt spinel weighs 1.62 carat and measures 8.20 x 5.89 x 3.92 mm, an oval shape that sits elegantly in many jewelry settings, and the faceted mixed brilliant cut has been executed to emphasize its exceptional cut and brilliance, making it a true centerpiece in any collection. The mixed brilliant cut combines step facets and brilliant facet arrangements to balance scintillation and table brightness, and in this stone the facets have been proportioned to maximize light return and to produce lively flashes of blue across the full face of the gem. The polish is excellent, which enhances surface luster and allows the eye to appreciate the gem without distraction, and because this spinel is untreated, with no enhancement, collectors and connoisseurs will value its natural state and optical purity.

Clarity is graded slightly included as evaluated at eye level, which means small natural inclusions are present but do not detract from the gem when mounted, and these slight inclusions are often expected in natural spinel and can actually confirm the stone as natural rather than synthetic. Color intensity is intense, with a vivid cobalt blue saturation that is characteristic of fine cobalt spinel, and the depth of color combined with the gemological attributes makes this specimen desirable to educated buyers seeking rarity and aesthetic impact. Origin is Vietnam, a source known for producing high quality cobalt spinels with strong blue hues, and provenance from Vietnam adds an element of geographic interest and market appeal. For purchasers who want a piece that performs well as jewelry and holds intrinsic value, this spinel is an outstanding choice. The Natural Gemstone Company stands behind the detailed description and presentation of this gem, and we encourage examination of the stone under magnification and in multiple lighting conditions to appreciate its cut precision, lively brilliance, and pure, intense color. Whether set as a solitaire, paired in a custom commission, or retained as an investment grade piece, this 1.62 carat oval cobalt spinel will command attention and serve as a memorable focal point in any collection.
