1.07 Ct. Blue Spinel from Ceylon (Sri Lanka)

If you are searching for a single stone that ends your quest for a meaningful, wearable, and entirely natural centerpiece, this 1.07 carat blue spinel from Ceylon is crafted to answer that search. The gem sits in a classic asscher octagon shape, with precise dimensions of 5.73 mm by 5.67 mm by 3.66 mm, proportions that translate to an elegant face up presence while remaining perfectly manageable for custom design. Buyers who want a gemstone that looks substantial on the finger, yet fits beautifully in refined settings, will immediately appreciate the balance this stone offers. The asscher cut, with its stepped facets and trimmed corners, creates a geometric symmetry that lends itself to clean, modern suspensions, and to vintage inspired designs that celebrate precision and clarity. At The Natural Gemstone Company we understand that size and shape matter most when a stone must sit as the hero of a bespoke piece, and this blue spinel checks every box.

For makers and clients who value optical performance and authenticity, this sapphire like spinel is particularly compelling. The gem is transparent, with a clarity grade described as very very slightly included when evaluated at eye level, which means the stone reads as eye clean in most settings, and will minimize the need for strategic hiding in the design. The dark color intensity gives it a rich, saturated blue that reads with depth in candlelight and daylight both, offering a dramatic contrast when paired with white diamond accents or a warm metal like rose gold. The polish is excellent, which ensures crisp facet reflections and an inviting surface finish that will photograph well and feel luxurious to the touch. Importantly, there is no enhancement, a quality that discerning collectors and ethical shoppers prize, because it guarantees the stone is naturally beautiful as it came from the Earth.

Practicality for custom jewelry work is where this spinel truly shines, and here are the reasons this gem should be at the top of your shortlist. The nearly square asscher octagon shape is ideal for a variety of mounting styles, including classic four prong solitaires, low profile bezel settings for daily wear, halo designs that amplify brilliance, and even east west or tension mounts for contemporary statements. The dimensions make it easy for jewelers to match existing settings or to design a new one without major structural changes, and the 1.07 carat weight provides a presence that feels luxurious without overwhelming most hands. For an engagement ring client who wants a stone that looks substantial yet is comfortable and secure, this gem’s depth and table proportions allow for secure prong placement and predictable light return. Designers creating cocktail rings, pendants, or stud earrings will also find the stone’s face up area and symmetry simplify setting choices, helping to keep labor efficient while maximizing aesthetic impact.

Choosing a gemstone is about finding the piece that resolves a set of needs, and this Ceylon blue spinel does exactly that. For the person who wants an elegant engagement ring that stands apart, for the collector who values natural provenance and no enhancements, and for the jeweler who needs a well proportioned, easy to set stone that will delight a client, this asscher cut spinel is a perfect match. The provenance from Sri Lanka lends a respected history to the gem, while the dark, saturated blue and excellent polish ensure it reads as both refined and significant on the hand. At The Natural Gemstone Company we curate stones that close the search, and this 1.07 carat asscher octagon blue spinel is a confident answer for anyone designing bespoke jewelry that must be beautiful, durable, and unmistakably natural.
