7.02 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This 7.02 carat oval color change sapphire is presented with precise cut and proportion data to satisfy discerning collectors. The stone measures 11.79 by 9.67 by 7.39 millimeters, yielding a depth of 7.39 millimeters and a depth ratio of approximately 68.9 percent, a proportion that balances face up spread with optimal light return for an oval form. The mixed brilliant cut combines a brilliant facet arrangement on the crown with a complementary faceted pavilion, a design chosen to maximize both scintillation and color saturation. The crown facets create dynamic brilliance and pinpoint scintillation, while the pavilion facet geometry has been executed to promote even face up color and to reinforce the color change phenomenon. Clarity is graded as very very slightly included at eye level, meaning that minor internal features are present under magnification but do not detract from the gem when worn. The material is transparent, with vivid color intensity and an excellent polish, producing crisp facet junctions and lively reflections. This sapphire exhibits a notable color change, shifting from a cooler blue violet in daylight conditions to a richer purplish hue under incandescent lighting, and the mixed brilliant cutting plan has been tailored to preserve both the daylight tone and the incandescent warmth without compromising windowing or extinction. There is no enhancement, the stone is natural and untreated, and its origin is Ceylon Sri Lanka, a source known for producing sapphires with transparent clarity and lively chroma.

The ethical provenance of this sapphire is a central consideration for conscientious buyers, and The Natural Sapphire Company maintains rigorous sourcing standards to ensure responsible practices. This gem was procured through channels that prioritize traceability and community benefit, and our sourcing protocols include direct relationships with vetted miners and partners in Sri Lanka, documentation of chain of custody, and support for local programs that promote fair wages and environmental stewardship. Because this stone is unenhanced, the lack of heat treatment or fracture filling preserves its natural character and avoids the additional processing that can obscure origin verification. For buyers who prioritize verification, we provide independent gemological reporting and origin documentation upon request to substantiate the Ceylon Sri Lanka provenance and the no enhancement statement. The Natural Sapphire Company emphasizes transparency at every stage, from rough procurement to lapidary finishing, and our cutters apply time honored techniques together with modern precision to maximize yield while minimizing waste and environmental impact. By choosing this sapphire a collector is supporting an approach that values responsible supply chains, artisanal skill, and the intrinsic beauty of unaltered corundum.

For the conscious consumer assembling a refined collection, this 7.02 carat oval color change sapphire is both a technical exemplar and a practical choice for wearable luxury. With a Mohs hardness of 9, sapphire ranks as one of the most durable gemstones suitable for daily wear, and the robust proportions of this oval make it adaptable to a variety of settings. Recommended mounting options include a low profile bezel or a secure four or six prong setting designed to protect the girdle and pavilion while allowing sufficient light to enter the crown for color change display. Designers may choose a warm metal such as 18 karat yellow gold to accentuate the sapphire under incandescent light, or a cool metal such as platinum to emphasize the daytime blue violet tone, and the stone’s vivid intensity will hold up well against larger design elements. Care is straightforward, gentle cleaning with warm soapy water and a soft brush will preserve polish and brilliance, and professional inspection is recommended if the setting sustains impact. For clients seeking bespoke commissions, The Natural Sapphire Company offers design consultation to integrate this sapphire into an engagement ring, pendant, or statement piece that respects both the gem’s optical behavior and ethical provenance. This sapphire is a rare combination of technical refinement, untreated natural origin, and responsible sourcing, making it an ideal addition to a collection curated for longevity, integrity, and measurable beauty.
