1.01 Ct. Purplish Pink Sapphire from Ceylon (Sri Lanka)

This heart shape purplish pink sapphire weighs 1.01 carats and measures 5.05 by 6.19 by 4.23 millimeters. It is cut as a mixed brilliant, combining a brilliant style crown with a geometrically optimized pavilion, and displays an intense color intensity with a clarity grade of very very slightly included, evaluated at eye level. The stone originates from Ceylon Sri Lanka and has been heat treated, a stable and widely accepted enhancement that refines color and improves overall transparency. The measured depth of 4.23 millimeters represents approximately seventy five percent of the average of its length and width, a proportion selected to balance face up spread with internal light return, and the gem exhibits an excellent polish across facet planes and girdle, producing crisp facet junctions and minimal surface abrasion.

The faceting geometry is engineered to maximize light play through controlled facet angles and precise symmetry. The mixed brilliant approach uses a relatively broad table and a crown of triangular and kite shaped brilliant facets to generate intense scintillation on the face up view, while the pavilion incorporates modified brilliant facets that function as geometric light guides, redirecting return light through the crown as a combination of broad flashes and pinpoint scintillation. In a heart outline the cleft and opposing lobes require exact mirror symmetry, and this example demonstrates well defined lobes with a sharply cut cleft, which preserves geometric integrity and prevents light leakage at the junctions. The result is an articulated interplay between flash and scintillation, the broad flash components accentuating the purplish pink hue, and the smaller scintillation facets breaking light into dynamic motion as the stone turns. Additionally corundum pleochroism is managed by facet orientation during cutting, aligning facet windows to favor the most desirable blend of purple and pink color vectors when viewed face up.

From a trade and setting perspective the combination of intense color and very very slight inclusions yields excellent presence in jewelry applications while retaining durable performance for everyday wear. Heat treatment is common for Ceylon sapphires and in this instance it accomplishes color stabilization without compromising structural integrity. The stone benefits from settings that present the table to light with minimal obstruction, such as a low bezel with open shoulders or a semi bezel with prong support through the lobes to protect the cleft, thereby maximizing brilliance while guarding against mechanical stress. For collectors and designers seeking a finely cut heart shaped corundum with technical precision, The Natural Sapphire Company offers detailed provenance and cutting reports upon request, and can advise on mounting options that enhance face up color while preserving optical performance. This gem exemplifies controlled faceting, disciplined proportions, and refined polish, making it an excellent choice for bespoke work where geometric light performance and saturated purplish pink tone are required.
