1.53 Ct. Spinel from Ceylon (Sri Lanka)

This exceptional blue spinel is a superb example of natural gem quality, presented by The Natural Gemstone Company, and it stands out immediately for its balance of weight, dimensions, and visual appeal. The gem weighs 1.53 carats and measures 7.67 x 5.80 x 3.55 millimeters, in a refined cushion shape that blends classic silhouette with contemporary elegance. The cut is a mixed brilliant, which combines the pavilion mechanics of brilliant faceting with a crown designed to maximize scintillation, providing a lively display of light under varied lighting conditions. The medium color intensity offers a rich and accessible blue that reads beautifully in different settings, and the excellent polish ensures that every facet faces a mirror like finish, enhancing both sparkle and depth. Overall proportions and facet alignment have been executed to highlight the natural color and clarity of this spinel, making it immediately attractive to connoisseurs and collectors who value both aesthetic and technical merit.

The mixed brilliant cut on this cushion spinel is particularly noteworthy because it optimizes both brilliance and color, transforming incoming light into vibrant flashes and a pleasing body color. The pavilion utilizes a series of triangular and kite shaped facets that return light efficiently, while the modified crown allows for larger table proportions that preserve the gem s color saturation. This combination produces an eye catching play of white light and colored flash, which gives the stone a dynamic presence on the finger or in a display. The excellent polish contributes to crisp facet junctions and clean facet planes, which are essential for maximizing return of light and visual contrast. For buyers who appreciate the technical specifics of cutting, the mixed brilliant approach here is a deliberate choice to maintain weight while still achieving lively scintillation and strong color presentation.

Clarity is evaluated as very slightly included at eye level, a grade that signals minimal internal features that do not detract from the gem s overall appearance to the unaided eye. In practical terms this means the spinel is essentially eye clean, with inclusions that are insignificant and often serve as natural fingerprints of formation rather than flaws. For an educated buyer, very slightly included is an excellent balance between purity and value, because spinel crystals that are larger and fully clean at this price remain uncommon. The absence of any enhancement is an important attribute, which confirms this stone has not undergone heat treatment or oiling to alter or intensify its color or clarity. Untreated spinel from Sri Lanka is particularly desirable because it offers transparency to provenance and natural color, qualities that collectors and ethical buyers increasingly prioritize. The medium color intensity provides a versatile hue that can be set in either white or yellow metal confidently, and the transparent body combined with the mixed brilliant faceting allows for a strong sense of depth and life.

Origin from Ceylon Sri Lanka adds another layer of value and historical significance to this spinel, because Sri Lankan gemstones have a long established reputation for fine color and reliable gemological characteristics. Ceylon spinels often exhibit clean crystal formation and attractive tonalities, and provenance from this island enhances both collectible interest and market desirability. From a practical standpoint this spinel s hardness of approximately eight on the Mohs scale makes it well suited to everyday jewelry such as rings, pendants, and earrings, while its excellent polish and durable structure help maintain its visual appeal over time. For the buyer considering this stone as an investment or family heirloom, the combination of natural origin, no enhancement, and superior cutting makes it a strong candidate for long term appreciation. The Natural Gemstone Company is committed to transparent description and ethical sourcing, and we present this 1.53 carat cushion blue spinel as a centerpiece quality gem that will anchor any collection or bespoke commission with confident beauty and credible provenance.
