1.07 Ct. Spinel from Ceylon (Sri Lanka)

If you are searching for a singular gemstone that ends your quest for the perfect engagement ring centerpiece or the next standout treasure for a serious collection, this 1.07 carat round blue spinel from Ceylon is the precise answer, and The Natural Gemstone Company is proud to present it. This gem meets the most exacting standards that discerning buyers seek, with a transparent body, an eye clean clarity grade evaluated at eye level, and a mixed brilliant cut that maximizes fire and scintillation while maintaining a pleasing, modern outline. The proportions are exceptional for a stone of this weight, with dimensions of 6.05 x 6.06 x 4.18 mm that sit beautifully in a range of settings from a delicate solitaire to an elegant halo or a bespoke three stone design. The medium intense color intensity gives this spinel a rich, vivid blue that reads as timeless and versatile, while the excellent polish ensures every facet reflects light with a crisp, lively brilliance. Most importantly, this spinel is completely natural and untreated, with no enhancements, which further elevates its rarity and desirability for buyers who value authenticity and natural beauty.

Rarity is where this gem truly distinguishes itself from similar options on the market, because blue spinel in this combination of weight, color and origin is uncommon. Many spinels of comparable size tend to exhibit paler blue tones or are heat treated or dyed to achieve deeper hues, but this piece delivers a medium intense blue straight from its source in Ceylon Sri Lanka without any enhancement. The origin matters, because Sri Lankan spinels are renowned for their clarity and lively color saturation, and finding an untreated round spinel at just over one carat that remains eye clean is a rare event for collectors and jewelers alike. In terms of size, 1.07 carat is a sweet spot that feels substantial on the finger without overpowering delicate settings, and the near perfect round outline at 6.05 x 6.06 mm speaks to meticulous cutting. The mixed brilliant cut is specifically chosen to amplify that depth of color while preserving brilliant light return, which is especially important with blue spinels where color and sparkle must be balanced. When compared to similarly sized stones, this gem’s combination of medium intense color, eye clean clarity and natural origin sets it apart as a scarce and highly sought after piece.

Choosing this Ceylon blue spinel as your centerpiece resolves the dual needs of beauty and rarity, whether your priority is an engagement ring that will captivate for a lifetime, or an investment grade gem to enrich a curated collection. The Natural Gemstone Company stands behind every facet of this offering, and we are available to advise on the ideal setting to showcase the stone’s color and brilliance, from platinum solitaires that intensify the blue to rose gold mounts that add warmth and contrast. For collectors, the fact that the stone is untreated and from a respected Sri Lankan source increases its long term appeal and provenance. For couples shopping for engagement rings, the stone’s comfortable 6.05 mm diameter and striking medium intense blue ensure it will be noticed and admired without feeling ostentatious. We can provide additional detailed imagery, mounting recommendations, secure shipping options and expert guidance to ensure your selection fits your vision perfectly. If your search has been for rarity in both size and color, your search truly concludes here with this exceptional 1.07 carat blue spinel from The Natural Gemstone Company, a natural, untreated, eye clean gem that promises enduring beauty and a distinct place in any fine jewelry collection.
