1.54 Ct. Pink Spinel from Burma (Myanmar)

This Burmese spinel offered by The Natural Gemstone Company is a transparent cushion shape weighing 1.54 carat, with dimensions 7.94 x 6.23 x 4.03 mm. The gem is executed in a mixed brilliant cut, combining a faceted crown arrangement with a modified brilliant pavilion to produce balanced light return and strong scintillation. Its measured depth of 4.03 mm yields a depth proportion of approximately 57 percent when compared to the average of its length and width, a proportion that sits within the range that optimizes both face up area and internal light performance for a cushion outline. Clarity is evaluated as very slightly included at eye level, a practical grade for spinel that indicates minor natural inclusions which do not materially interrupt the overall transparency or visual impact. Color intensity is light, a delicate pink that is evenly distributed across the table surface, and polish is graded excellent, indicating crisp facet junctions and accurately executed facet planes. There is no enhancement applied to this stone, the material is natural, and its provenance is Burma Myanmar, a region renowned for producing spinels with classic, appealing pink tones derived from trace chromium.

From a faceting and optical design perspective the mixed brilliant cut is deliberately chosen to reconcile color saturation with brilliance. The crown facet pattern employs multiple kite and star facets that moderate the table size in order to concentrate color in the pavilion, while the pavilion uses a modified brilliant schema with additional lower girdle facets to amplify return and create dense scintillation. This configuration maximizes return given the stone specific indices, while the relatively shallow to medium depth proportion preserves a substantial face up appearance. The excellent polish enhances flash and return, because light scattering at facet surfaces is minimized. The clarity grade very slightly included implies inclusions are small and isolated, often fine crystals or rutile needles typical of natural spinel, and their placement in this example avoids the principal light paths. The lack of enhancement is significant for collectors and connoisseurs, it means the color and clarity are intrinsic to the natural crystal lattice, magnesium aluminum oxide MgAl2O4, and have not been altered by heat or diffusion, preserving both optical and long term material integrity.

When compared to more common gem materials this pink spinel demonstrates a distinctive balance of brilliance and color stability. Spinel has a refractive index range approximately 1.718 to 1.736, which places it below corundum and well below diamond, yet above many silicate and phosphate gemstones. The relative dispersion of spinel is low, producing modest fire, but the cubic crystal system renders spinel isotropic, meaning it has no birefringence and displays color uniformly from all viewing angles. This uniformity contrasts with pleochroic materials such as tourmaline, where color saturation can vary with orientation. Compared to ruby which is corundum with slightly higher refractive index, spinel will exhibit marginally less brilliance under identical cuts, however the mixed brilliant faceting strategy used in this cushion piece compensates by producing concentrated scintillation and lively flash, especially in small to medium carat sizes. Versus diamond, which exhibits strong fire and brilliance due to high refractivity and dispersion, spinel offers a subtler, gemmy brilliance that emphasizes body color and scintillation rather than spectral fire, a quality that appeals to buyers seeking colored stone presence rather than pronounced dispersion. In practical terms, this spinel stands out because its isotropic optics and well executed mixed brilliant faceting generate a balanced visual experience where color, flash, and surface polish are all optimized without sacrificing one attribute for another.

From the perspective of craftsmanship and setting considerations, this cushion pink spinel adapts well to a variety of mounting approaches that enhance both protection and optical performance. The cushion silhouette with its measured depth and generous face up area is ideally suited to a four or six prong head when the goal is to maximize perceived size and light entry, and it also responds well to a low bezel for a contemporary look that protects the girdle and edges. For pieces where color is paramount, a white metal surround will increase apparent light return, while a warmer alloy such as rose or yellow gold can visually deepen the pink tone by contrast. The stone is durable, exhibiting a Mohs hardness of eight, making it a solid choice for rings and everyday wear when set securely, and the excellent polish aids in resisting surface abrasion. For routine care use warm soapy water and a soft brush, and consult a professional gemmologist before subjecting the stone to steam cleaning or ultrasonic methods if inclusions are near facet junctions. At The Natural Gemstone Company we document each gemstone with detailed imagery and measurements, and we are available to provide additional photomicrographs or facet maps upon request, ensuring that technical buyers and collectors have the precise information needed to evaluate optical behavior, cutting geometry, and suitability for the intended jewelry application.
