6.45 Ct. Blue Sapphire from Burma (Myanmar)

This C. Dunaigre certified Blue heart shaped sapphire weighs 6.45 carats, with dimensions of 11.09 x 13.15 x 6.51 mm, and presents as a precise heart silhouette executed with a mixed brilliant cut combining pavilion brilliant facets with a modified crown that balances scintillation and color saturation. The stone exhibits medium color intensity in a classic Burmese blue, with a clarity grade described as very slightly included when evaluated at eye level, and an excellent polish that preserves sharp facet junctions and crisp facet outlines. The mixed brilliant faceting enhances return of light through a larger table and controlled crown angles, yielding lively scintillation without sacrificing depth of color. There is no enhancement, confirming a completely natural state, and the origin is Burma, a provenance renowned for its strong natural color and desirable crystal growth characteristics. The certification from C. Dunaigre documents these attributes, supporting both the gemological integrity and the specimen s suitability for fine bespoke jewelry.

For customization, the heart shape and the gem s specific proportions make it exceptionally versatile for a range of settings, from classic solitaires to complex couture pieces. A four or six prong setting with a tailored V prong to protect the cleft will maximize brilliance while securing the point, whereas a low bezel will offer additional protection for everyday wear while slightly muting peripheral light return. A fine halo of micro pavé diamonds will accentuate spread and apparent diameter, creating a larger visual impact and increasing perceived color contrast. In three stone compositions, tapered baguettes or kite facets complement the heart silhouette, maintaining symmetry across the composition. For pendant work, a hidden bale or open back bezel will preserve table exposure and allow light transmission, and for earrings a matched pair or a single asymmetric companion gem can be created using precision matching of color and cut parameters. Metal choices such as platinum or 18 carat white gold will emphasize the stone s blue tone, while 18 carat yellow or rose gold can warm the presentation and accentuate the Burmese hue. The Natural Sapphire Company can provide technical CAD renders, stone setting profiles, and bespoke mounting recommendations, including prong thickness, seat depth, and crown clearance, allowing master setters to optimize security, light performance, and wearability for any custom commission.
