0.52 Ct. Spinel from Ceylon (Sri Lanka)

This is a beautifully transparent purple spinel weighing 0.52 carat, offered by The Natural Gemstone Company, cut into a classic cushion shape that measures 4.87 by 4.82 by 2.64 millimetres. The gem features a mixed brilliant cut with an expertly faceted pavilion and crown, and it displays a medium color intensity that sits in a pleasing purple range with subtle bluish undertones visible under varied lighting. The clarity is graded as very very slightly included when evaluated at eye level, which means the stone looks clean to the unaided eye while retaining natural internal characteristics under magnification. The polish is excellent, and the gem has undergone no enhancement, an important attribute for discerning buyers who value natural, untreated stones and documented origin from Ceylon, Sri Lanka.

Weight is a primary determinant of value and rarity in gemstones, and the half carat class occupies a unique position in the market. At 0.52 carat this spinel is larger than many common collector pieces and yet compact enough to be versatile for a wide range of settings. In colored gemstones, values generally rise in a non linear fashion with weight, meaning that a gem that crosses a size threshold can command noticeably higher prices per carat than slightly smaller examples. For spinel, which is rarer in vivid and saturated purple tones than in some other hues, achieving a clean, well colored specimen at a half carat size is a notable occurrence. The measured dimensions of 4.87 by 4.82 by 2.64 millimetres translate into a pleasing visual presence in a ring or pendant, and because spinel has a relatively high specific gravity the stone feels solid and substantial for its physical size, adding to the perception of value and permanence.

Clarity and cut are critical to how a gem performs, and this purple spinel showcases both attributes in a way that enhances its rarity and desirability. The clarity grade of very very slightly included, evaluated at eye level, indicates that inclusions are minimal and do not interfere with the flow of light through the stone. Such clarity allows the mixed brilliant cutting style to deliver crisp facet reflections, strong scintillation, and an even spread of color across the table and crown. The cushion outline lends a soft, elegant profile that complements the modern mixed brilliant facet arrangement, marrying vintage charm with contemporary brilliance. Excellent polish ensures that light is returned with minimal absorption or diffusion, which maximizes visual impact even in moderate light, a performance trait that educated buyers recognize as a driver of long term satisfaction and resale potential.

Origin and treatment history further define a gemstone s market position, and this spinel comes to you unheated and untreated from Ceylon, Sri Lanka, a source with a long and respected history for producing fine spinels. Sri Lankan spinels are valued for their natural stability of color and for yielding crystals that adapt well to precision cutting techniques, which in turn allows cutters to extract weight while preserving brilliance. The lack of enhancement is an important consideration for collectors and investors who place a premium on natural state material, because untreated stones often retain value more consistently over time. From a gemological perspective, a clean, medium intensity purple spinel from Ceylon, polished to an excellent finish and presented at just over a half carat, represents a balanced combination of provenance, aesthetics, and rarity.

For buyers seeking a stone that performs both as an everyday wearable and as a collector s piece, this 0.52 carat cushion purple spinel is a compelling choice. Its dimensions provide enough presence to center a delicate solitaire ring or to anchor a more elaborate custom setting, while its clarity and cut ensure that it will sparkle under both natural and artificial light. The Natural Gemstone Company stands behind the gem s quality and provenance, and we can advise on mounting options that emphasize the weight and cushion silhouette so that the stone reads larger on the finger. For those considering this spinel as an investment or as a meaningful gift, the combination of half carat weight, untreated Ceylon origin, very very slightly included clarity at eye level, mixed brilliant cutting, and excellent polish creates an item that is both rare and practical, offering aesthetic appeal and long term desirability.
