0.90 Ct. Pink Spinel from Ceylon (Sri Lanka)

This 0.90 carat cushion shape pink spinel is a finely transparent gem that combines precise proportions with a lively pink hue, making it an outstanding choice for a refined jewelry commission. The stone measures 5.31 x 5.07 x 3.92 mm, and its mixed brilliant cut has been executed to maximize both scintillation and face up spread, so the gem reads larger than its weight might suggest. Clarity is graded very very slightly included, evaluated at eye level, which means that under normal viewing conditions the inclusions are minimal and do not interrupt the gem’s visual purity or brilliance. The color is described as medium intensity, offering an appealing balance between saturation and brightness that is versatile for both daytime and evening wear. The polish is excellent, which enhances light return across the pavilion and crown facets, and importantly this spinel is natural and untreated, with no enhancement, a characteristic that is highly valued by discerning collectors and responsible buyers. Origin is Ceylon, Sri Lanka, a source with a long pedigree for producing high quality spinels, and this provenance adds historical and gemological interest to the piece, a point we carefully document at The Natural Gemstone Company.

From a gemological standpoint, spinel is an exceptionally practical and attractive choice for everyday jewelry, and this example demonstrates those strengths clearly. Spinel typically has a refractive index around 1.712 to 1.718, a specific gravity in the neighborhood of 3.58 to 3.61, and is an isotropic gem, so it does not exhibit birefringence. The Mohs hardness of spinel is approximately 8, which places it well above many common gems used in rings and bracelets, and combined with its lack of prominent cleavage the stone exhibits very good toughness. Those material properties mean the gem resists scratches and chips under normal wear far better than softer gems, and the absence of cleavage planes reduces the risk of breakage from incidental knocks. The mixed brilliant cut employed in this cushion accentuates the gem’s internal fire and reflective return, while the excellent polish ensures minimal light leakage, so the overall result is a brilliant, durable stone that performs beautifully in ring settings where daily exposure is expected.

For the educated buyer considering this spinel from The Natural Gemstone Company, several practical considerations reinforce its value proposition. The combination of natural, untreated origin from Ceylon, eye level clarity graded very very slightly included, and the attractive medium color intensity creates a gem that is both rare and wearable, characteristics that support long term desirability and stable market demand. The dimensions and weight make it ideal for a classic solitaire ring, a halo setting that amplifies perceived size, or an elegant pendant that showcases the cushion silhouette. For daily wear we recommend secure settings such as four to six prongs with a slightly raised girdle profile, or a protective bezel if additional shielding is desired for active wearers. Care is straightforward, warm soapy water and a soft brush will keep the gem bright, and spinel’s stability to heat and common cleaning methods means it tolerates routine ultrasonic and steam cleaning in most cases, although we advise inspection of the mounting and any adhesives prior to such treatments. This pink spinel represents a considered choice for collectors and connoisseurs who prioritize natural origin, durable gemological properties, and aesthetic refinement, and our team at The Natural Gemstone Company is available to provide certification details, additional photographs, and custom setting recommendations to ensure the stone is presented to best advantage.
