1.70 Ct. Pinkish Purple Sapphire from Ceylon (Sri Lanka)

This 1.70 carat cushion shape pinkish purple sapphire from Ceylon, Sri Lanka, is a fine example of what discriminating buyers seek when assessing natural, untreated corundum. With dimensions of 7.88 by 6.18 by 3.53 millimeters, the gem displays a well judged face up size for its weight, and a pavilion depth that works with the cutter s decisions to balance color and brilliance. The mixed brilliant cut marries a faceted crown designed to return light to the eye, with pavilion faceting that promotes scintillation, and the overall finish is supported by an excellent polish that enhances surface luster and ease of cleaning. Clarity is graded slightly included when evaluated at eye level, indicating the presence of small natural inclusions that are visible to a trained observer but do not materially reduce the gem s transparency or light performance. Importantly this sapphire has received no enhancement, and its natural state together with Ceylon provenance contributes materially to rarity and resale desirability. The Natural Sapphire Company stands behind the accuracy of these descriptions and the integrity of the stone s origin and treatment history.

Color and cutting are the principal drivers of this sapphire s visual impact, and in this example the intense color intensity is unusually appealing. The pinkish purple hue sits between classic pink sapphire and violet tones, offering a lively color that shifts subtly under different lighting, exhibiting gentle pleochroism so that warmer incandescent light emphasizes pink facets while daylight brings forward the purer purple aspects. Because sapphires have a refractive index lower than diamond, they do not display diamond style fire, yet a well executed mixed brilliant cut channels brilliance in a different and often more wearable way. The result is focused flashes of white light and colored scintillation that read as lively and saturated rather than the broken fire associated with diamond. Compared with common gemstones like amethyst and tourmaline, this Ceylon sapphire combines superior hardness at nine on the Mohs scale with a high polish retention and resistance to abrasion, which means it will maintain its crisp facet edges and brilliance through daily wear. Compared with spinel, which can be visually similar in hue but lacks strong pleochroism and historical cachet, a natural untreated Ceylon sapphire carries premium value and collector interest.

For the educated buyer, value is determined by a combination of color, cut, clarity, treatment status, and origin, and this sapphire scores highly across those categories. The untreated nature of the stone adds a measurable premium, because heat treatment has long been an accepted enhancement in the trade, and an unheated gem of intense Ceylon tone is relatively scarce. Slight inclusions are a natural fingerprint that confirm provenance and crystallization history without materially compromising eye visible beauty, and the excellent polish and balanced proportions maximize face up color and return of light. In practical terms the gem s approximately fifty percent depth and cushion outline creates an elegant silhouette that sits attractively in a solitaire or halo setting, and the stone s durability supports everyday wear in rings as well as in pendants and bespoke pieces. The Natural Sapphire Company can provide full documentation of origin and treatment history, and we recommend routine gentle cleaning with warm soapy water and a soft brush to preserve the luster, avoiding harsh blows and strong chemicals. For a buyer who values natural origin, precise grading, and exceptional color performance that stands distinct from more common colored stones and from diamond brilliance, this 1.70 carat Ceylon pinkish purple cushion sapphire represents a compelling and enduring choice.
