You are searching for a gemstone that solves a very particular set of desires, a stone that reads as both rare and wearable, a stone that will be the focal point of an engagement ring or the prized piece in a collector s cabinet. This oval shape transparent blue spinel, offered by The Natural Gemstone Company, answers that search with precision. At 0.73 carat and measuring 6.32 x 4.80 x 3.24 mm, this gem balances presence and practicality, giving a clear visual impact without overpowering a refined setting. Origin Ceylon Sri Lanka, no enhancement, gives the confident reassurance of natural provenance, and the gem s medium intense color intensity paired with excellent polish ensures it will draw attention wherever it is set. For anyone seeking an untreated gem with both heart and technical merit, this stone is an ideal resolution.

The geometric faceting of this stone is a central reason it outperforms expectations, the mixed brilliant cut has been executed to maximize light play, the crown and pavilion facets are calibrated to capture and return light with lively scintillation and depth. The oval silhouette allows elongated flashes of brilliance when the stone moves, while the strategically placed brilliant facets break light into lively reflections that dance across the table and crown. Each facet plane has been cut to coordinate with the others, the angles and proportions creating a controlled environment for light to travel, reflect, and refract, resulting in a gem that seems to sparkle from within. The mixed brilliant style is particularly effective in an oval format, because it preserves depth of color while enhancing brightness, so the blue appears both saturated and luminous rather than flat.

Clarity and polish are the craftsmanship details that turn a fine material into a collector s or bride s dream, and this spinel is transparent with a clarity grade described as very very slightly included when evaluated at eye level, meaning that the gem reads as eye clean to most observers, while still retaining natural character. The excellent polish elevates every facet, producing crisp facet junctions and mirror like surfaces that feed the geometric faceting system and amplify that sought after play of light. The medium intense blue is emblematic of Ceylon Sri Lanka spinels, a hue that sits between vivid and deep, offering versatility in design because it contrasts beautifully with both warm and cool metals. Because there has been no enhancement, the color and clarity you see are the gem s true properties, which adds value for collectors and peace of mind for those designing an heirloom.

Practical needs matter as much as aesthetic ones, and this spinel stands up to daily wear while offering beauty that suits special moments, spinel s durability, with a hardness of eight on the Mohs scale, allows confident use in engagement rings and everyday pendants, while still being straightforward to set securely. The size 6.32 x 4.80 x 3.24 mm makes it an elegant center for solitaire settings and a refined focal point in multi stone rings, it photographs well and presents with a strong face up presence that reads larger than the carat alone might suggest because of its ideal proportions. Collectors and designers will also appreciate the gem s untreated state, and The Natural Gemstone Company can advise on mounting styles that best showcase the mixed brilliant faceting and the stone s oval geometry, ensuring the light performance remains the primary feature.
