Spinel 1.96 cts

Unlike ruby and sapphire, spinel is singly refractive, meaning light passes through it without splitting into two rays — a property that produces an exceptionally clean, direct brilliance. This characteristic gives fine spinel a vivid, almost electric presence in the hand, free from the doubling effect that can sometimes dull the perceived saturation of doubly refractive stones. Collectors who have compared the two side by side often describe spinel’s glow as more immediate and pure.

Spinel registers 8 on the Mohs hardness scale, placing it firmly in the range considered suitable for all forms of jewellery, including rings and bracelets subject to regular contact. It has no cleavage, which means it resists chipping far better than stones such as topaz or aquamarine. These physical properties make it a practical choice for a centrepiece stone in a setting intended for daily wear.

Spinel requires no special treatments to maintain its appearance and is stable under normal light and heat conditions, unlike some colour-sensitive stones. Cleaning with warm soapy water and a soft brush is entirely sufficient and safe; ultrasonic cleaners are generally considered acceptable for untreated specimens, though caution is always advisable with any fine gemstone. Storage away from harder stones such as diamonds will prevent surface abrasion over time.

Spinel has attracted growing interest among serious collectors over the past decade, particularly fine examples from classic origins such as Burma’s Mogok Valley, as the market recognises its rarity relative to ruby at comparable quality grades. Certification from a reputable gemological laboratory — such as GIA, Gübelin, or SSEF — is strongly recommended, as it documents origin, treatment status, and quality characteristics that directly influence value. An unheated, origin-confirmed spinel of fine colour and above one carat is considered a meaningful collector asset in today’s coloured stone market.
