1.70 Ct. Purple Star Spinel from Ceylon (Sri Lanka)

This translucent purple star spinel weighs 1.70 carat and presents as an elegant oval cabochon measuring 7.80 by 6.39 by 3.91 millimeters, a size and weight that places it firmly in the premium collector category for star spinels. The cabochon cut has been executed to maximize the asterism, producing a sharp, six ray star that centers well under a single light source and remains visible across a variety of lighting conditions. The color intensity is described as intense, showing a rich, saturated purple that is evenly distributed, which enhances the contrast of the white star and contributes directly to the gem's visual appeal and market desirability. Clarity is graded as very very slightly included at eye level, which in a translucent cabochon spinel is an advantageous trade off because the minor inclusions are responsible for the strong star effect while remaining unobtrusive to the unaided eye. The polish is excellent, providing a high lustre that accentuates color and asterism without any visible polishing lines or surface disturbances.

From a connoisseur and investment perspective this stone is notable for several reasons. It is natural and untreated, with no enhancement, which significantly increases its value relative to heat treated or diffusion treated alternatives. The gem is from Ceylon, Sri Lanka, a classic and well regarded source for high quality spinel material, and provenance from this region supports both aesthetic and resale credentials. At 1.70 carat this stone occupies a premium size bracket for star spinel, where the combination of carat weight, intense color, well defined star, and very very slightly included clarity makes it desirable for serious collectors and designers seeking an exceptional center stone. The Natural Gemstone Company stands behind the description and origin information, and this piece is ideally suited for a bespoke ring or pendant setting that allows the star to be viewed from above and under controlled lighting. For longevity care is straightforward, consisting of gentle cleaning with warm soapy water and avoiding prolonged exposure to harsh chemicals. For buyers who value natural provenance, gemological transparency, and classic asterism in a collectible size, this 1.70 carat purple star spinel represents a rare and compelling example.
