1.08 Ct. Purple Spinel from Ceylon (Sri Lanka)

One beautiful transparent 1.08 carat cushion shape purple spinel is presented with dimensions of 6.59 x 5.92 x 3.41 mm, faceted with a mixed brilliant cut, clarity grade slightly included evaluated at eye level, intense color intensity, and an excellent polish. The stone originates from Ceylon Sri Lanka, and it has been heat treated to enhance color stability and saturation. The form is a true cushion, combining softly rounded corners with a broad table, and the mixed brilliant cutting style balances large crown facets with pavilion facets intended to optimize light return. The weight and proportions are well suited to ring, pendant, and bespoke settings, and the excellent polish contributes to immediate surface luster. The Natural Gemstone Company provides this spinel with full disclosure of treatments and origin, and the listing is intended to reflect accurate gemological information for informed decision making.

The mixed brilliant cut on this cushion spinel is designed to produce a lively interaction of light, with the crown facet arrangement directing light into the pavilion and returning it as visible brilliance. The table is proportioned to present a strong face up presence, while the pavilion depth preserves internal light return, resulting in a balance between scintillation and stable color. Slight inclusions visible at eye level are minimal and do not materially diminish overall visual appeal, they serve as natural fingerprints of origin and formation. The excellent polish ensures that light is not impeded at the surface, allowing crisp facet junctions and well defined reflections. Because spinel is an isotropic mineral, the stone does not display pleochroism, and color appears consistent from most viewing angles, which contributes to dependable performance in finished jewelry.

Under natural daylight the intense purple of this spinel reads as a rich, saturated violet with cool undertones, and high angle sunlight will produce noticeable internal reflections from the mixed brilliant facet plan that enhance perceived depth. In clear direct sunlight the stone will exhibit strong bright flashes of white light from facet junction return and occasional flashes of deeper purple as light is filtered through the body color, producing an impression of depth and vitality. Under warm incandescent lighting the color will appear slightly warmer and more purple red in tone, with soft, velvety flashes and a greater sense of richness, while the brilliance remains controlled and elegant. Under cool white LED or fluorescent lighting the hue maintains intensity, and the higher color temperature emphasizes crisp white returns and a slightly cooler purple appearance, which is useful in settings where a modern, vivid look is desired. In low light conditions and candlelight the intense color takes on a deeper, more saturated appearance with subdued brilliance, emphasizing color depth rather than sparkle. The combination of intense body color and the mixed brilliant cut creates versatile optical behavior that is attractive in both high contrast and subdued lighting scenarios.

Practical considerations include the setting type and routine care, spinel being a durable gem suitable for daily wear when properly secured. The heat treatment applied is standard in the trade to improve color and is stable under normal wearing conditions, therefore routine jewelry maintenance is recommended rather than avoidance of light or occasional cleaning cycles. For jewelry design, a bezel or low profile prong setting will protect the cushion shape and preserve the pavilion proportions, while open back settings can increase face up brightness if desired. When compared to other collector stones, note that Fire Opal is an opal type distinguished by its warm orange to red body color and play of color when present, and Fire Opal represents a different material class with different care and optical characteristics. The Natural Gemstone Company provides transparent information on both spinel and opal types, and this purple cushion spinel is offered with clear specification of weight, dimensions, cut, clarity grade, polish quality, enhancement, and origin to support appraisal, design decisions, and confident acquisition.
