1.57 Ct. Greenish Blue Spinel from Ceylon (Sri Lanka)

One beautiful transparent 1.57 carat oval shape greenish blue spinel awaits at The Natural Gemstone Company, a gem that stands out for its intense hue and natural purity. The stone measures 7.23 x 5.97 x 4.99 mm and is fashioned in a mixed brilliant cut that balances lively crown facets with a well proportioned pavilion, producing scintillation that reads as both deep and lively in real light. Its clarity grade is very very slightly included evaluated at eye level, which means that the stone reads as eye clean to most observers while retaining internal character that tells of its natural origin. The polish is excellent, and the gem has no enhancement, which adds to its desirability for collectors and those seeking a truly natural piece. Origin Ceylon Sri Lanka lends provenance that seasoned gem buyers recognize, and the combination of color intensity and untreated status positions this spinel as a distinctive, trustworthy choice compared with many mounted and treated alternatives on the market.

Compared with blue sapphires, this greenish blue spinel offers a different value proposition, because spinel combines vivid saturation with a clarity and brilliance that can rival sapphire while often arriving in the market at a more accessible price point for comparable eye appeal. Versus tourmaline in similar teal shades, spinel shows superior hardness and polish retention, making it a better candidate for everyday wear in rings that see ongoing use. Compared with aquamarine and topaz, which can be visually appealing but sometimes lack the depth and brilliance of a well cut spinel, this Ceylon stone presents a richer, more intense appearance that still reads as modern and versatile. Collectors who appreciate untreated color will also recognize that natural spinel from Sri Lanka is both rare and classic, and that the mixed brilliant cut has been executed to maximize fire without sacrificing color, a balance many commercially produced stones struggle to achieve. For buyers who want a standout center stone that combines exceptional color, reliable durability, and natural provenance, this spinel offers a stronger overall package than many alternatives in its class.

When planning a custom piece, this 1.57 carat oval greenish blue spinel is remarkably adaptable, and it benefits from complementary stones and metal choices that highlight its unique tone. Set as a solitaire in platinum or 18 karat white gold, small white diamonds placed as a halo or as shoulder accents will lift the greenish blue tone, creating contrast that reads crisp and modern. For a warmer overall look, four or six accent melee in rose gold settings with small peach or champagne sapphires will add a soft warmth that complements the gem without overwhelming its natural intensity. Pairing this spinel with lighter blue aquamarine melee offers a tonal gradient that emphasizes the center gem, while pairing with mint peridot or light green tsavorite in small accent roles will accentuate the green component and create an elegant botanical palette. A three stone ring set with tapered baguette diamonds or tapered mixed cut sapphires flanking the oval center will visually lengthen the finger and showcase the cut facets, and a low profile bezel or half bezel can protect the stone for active wearers while still allowing the mixed brilliant cut to reflect light.

For a pendant or a custom bracelet, consider combining this spinel with a small row of contrasting white diamonds above it, or with alternating tiny teal sapphires to create a striking line piece that reads both vintage and contemporary. The strong polish and intense color intensity ensure that it will sing under gallery lighting in a storefront display, and the untreated origin Ceylon Sri Lanka will be an important talking point for customers who care about provenance. At The Natural Gemstone Company we recommend viewing this gem in daylight and under warm indoor light to appreciate how the greenish blue shifts and deepens with the environment, and we are happy to advise on metal choices, setting styles, and ideal accent stones to build a balanced custom design. Whether you are a collector seeking a rarity that compares favorably with sapphire and tourmaline, or a client planning a one of a kind jewelry commission, this spinel offers a compelling blend of beauty, durability, and natural integrity that makes it a superior choice for a centerpiece gem.
