1.36 Ct. Spinel from Ceylon (Sri Lanka)

This exceptional transparent 1.36 carat radiant shape blue spinel presents an immediate impression of refined elegance, with its precise dimensions of 6.86 x 5.99 x 3.84 mm, a radiant cut that maximizes light return, and an excellent polish that gives the table a bright, lively surface. The stone displays a medium color intensity that sits in a desirable zone between soft pastel blues and deeply saturated indigos, making it versatile for a wide range of jewelry designs. The clarity is graded as very very slightly included, evaluated at eye level, which means the gem appears clean to the naked eye while retaining enough natural character to avoid the sterile look of overworked material. Importantly, there is no enhancement, so the color and clarity you see are entirely natural qualities from the crystal itself. This combination of an appealing size, a precise radiant cut, balanced color, and excellent polish creates a gemstone that reads as both classic and contemporary, capable of elevating a solitaire ring, a refined pendant, or a refined pair of earrings.

When comparing this blue spinel to other blue gemstones on the market, several strengths stand out for discerning buyers who value long term beauty and authenticity. Compared to many sapphires, which are often heat treated to enhance color, this spinel is completely untreated, offering a rare example of unmodified natural color, which collectors and connoisseurs prize for its transparency in provenance and treatment history. Against tanzanite, which can display rich trichroic color but is softer and more prone to wear, spinel is notably durable, making it a better choice for daily wear. Compared to blue topaz, which is commonly irradiated to produce its hue, this Ceylon spinel offers a more natural and complex blue, with subtle depth and velvety undertones that change attractively with light. The radiant cut further distinguishes this stone from many mixed cuts used in mass market gems, because the cut geometry of this piece is fashioned to enhance face up brilliance and to maintain an elegant profile in the setting, rather than simply maximizing weight retention.

The origin of this spinel, Ceylon Sri Lanka, contributes meaningfully to its value and desirability, and it is a vital part of the gem story that serious buyers appreciate. Sri Lanka has a long established history as a source of exceptional gemstones, and Ceylon spinels are known for their refined, often slightly muted blues that combine clarity with a softness that is both sophisticated and rare. The geological conditions in Ceylon, involving high grade metamorphic terrains and specific trace element chemistry, encourage the formation of spinels with appealing optical qualities and stable color, qualities that are difficult to find in material from many newer or less studied sources. Provenance from Ceylon also carries a cultural and historical cachet, because collectors and gem historians recognize the island as a place that has produced high quality gems for centuries. When you choose a Ceylon spinel, you are not only selecting a beautiful mineral specimen, you are investing in a piece of geological and human heritage, a gem whose origin adds an extra layer of authenticity and narrative to any jewelry commission.
