1.30 Ct. Cobalt Spinel from Ceylon (Sri Lanka)

From the moment the earth first formed the crystals that would one day become this stone, a story began that reaches forward to you. This blue cobalt spinel was born in the rich gem gravels of Ceylon, Sri Lanka, a place famed for producing gemstones with character and depth. Weathered by time and shaped by nature, the rough crystal arrived at our workshop with a rare combination of color and clarity. As a gemstone specialist at The Natural Gemstone Company I have handled many specimens from the region and I can tell you that a cobalt spinel of this nature carries geological history in every facet. The dark color intensity is a signature of its cobalt content and the transparency that allows light to pass through confirms the quality that only careful formation can produce.

Weighing 1.30 carat, this oval gem asserts its premium status from the first glance. Carat weight is more than a number, it is a measure of presence and proportion, a balance between size and brilliance. At 1.30 carat this stone is large enough to command attention while remaining elegant and wearable, translating into versatility for bespoke jewelry. Its dimensions of 7.44 by 5.91 by 4.10 mm give it an ideal profile for classic engagement rings and refined pendants, offering a pleasing spread on the finger without overwhelming the setting. The mixed brilliant cut has been chosen to amplify this gem s natural strengths, marrying scintillation with depth so that each movement produces a controlled dance of light.

During the cutting process the goal was to reveal the gem s inherent soul. Skilled cutters worked to respect its original crystal form while shaping an oval that maximizes light return. The mixed brilliant arrangement allows for both intense fire and deep, velvety color, which is especially important with dark color intensity specimens. Every facet was considered, and the excellent polish brings each plane to a mirror finish that enhances sheen and face up appeal. The clarity grade is very very slightly included when evaluated at eye level, a testament to the cleaner nature of this rough material that also contributes to its premium valuation. No enhancement was performed on this cobalt spinel, which means you are acquiring an untreated gem that carries its natural character unaltered.

As a representative of The Natural Gemstone Company I place emphasis on provenance and integrity. This piece comes from Ceylon, Sri Lanka, and its origin informs taste and tradition as much as its physical attributes do. Ceylonese gemstones have been prized for centuries, and this spinel carries that lineage into modern design. The combination of 1.30 carat weight, a refined oval mixed brilliant cut, very very slightly included clarity, dark color intensity, and an excellent polish makes it a premium offering that will sit beautifully in gold or platinum. It promises to be a focal point in any setting and a stone that will age gracefully while maintaining its visual impact.

If you imagine this gem as the centerpiece of a bespoke commission, picture how its dark blue will contrast with warm yellow gold, how its depth will add mystery in a halo design, and how its 7.44 by 5.91 by 4.10 mm dimensions will provide comfortable wear for everyday use. At The Natural Gemstone Company we are here to guide you through setting choices, certification, and care so that your 1.30 carat cobalt spinel retains its allure for generations. This untreated, Ceylon origin gem is a rare opportunity to own a premium natural spinel, and I would be pleased to discuss mounting options, detailed images, or certification to help you make this stone the next chapter in your jewelry story.
