1.60 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.60 carat cushion shape blue sapphire presents itself with graceful proportions, measuring 7.34 by 5.48 by 4.28 mm, and a refined mixed brilliant cut that balances sparkle with depth. At first glance the gem displays a medium intense blue, a color intensity that is prized for offering vivid presence without appearing overly dark, allowing the stone to read clearly on the finger and in jewelry settings. The clarity is graded as very slightly included at eye level, which translates to inclusions that do not distract from its overall beauty under normal viewing conditions. The cutting and excellent polish maximize light return, producing crisp facet reflections and a pleasing scintillation that emphasizes the sapphire stability and color. This sapphire has undergone controlled heat treatment, a standard and accepted enhancement in the trade, applied to stabilize and improve its color and to subtly improve internal clarity, while keeping its natural character intact. The origin of this sapphire is Ceylon Sri Lanka, a provenance that carries historical and market significance, and the piece is offered by The Natural Sapphire Company, where gemological standards and transparent information are central to the buying experience.

For the informed buyer the technical details matter, so it is important to articulate what each element contributes to value. The cushion shape with a mixed brilliant facet architecture is deliberately chosen to balance weight retention with optical performance, giving the stone a lively table and well dispersed flashes. The dimensions in combination with the 1.60 carat weight indicate a well proportioned stone that will sit confidently in custom or ready made settings. Medium intense color intensity is often preferred by connoisseurs because it preserves tonal richness and saturation, while remaining versatile across lighting environments and complementary metals. Clarity graded as very slightly included at eye level suggests that the stone is effectively eye clean to most observers, and the inclusions present are characteristic of natural corundum, providing internal fingerprinting that affirms the gem is natural. Heat treatment in Ceylon is typically a controlled process that improves color distribution and reduces the visual impact of some surfaces or internal features, and it is widely accepted by both gemological laboratories and the trade when disclosed transparently, as we do at The Natural Sapphire Company.

The journey of this Ceylon sapphire from mine to market is part of what gives it story and provenance. It began in the gem bearing gravels and weathered metamorphic deposits of Sri Lanka, where local miners and small scale operations concentrate on locating pockets of gem quality corundum. After initial recovery, the rough is sorted by experienced hands to separate material with desirable color and clarity. In many cases the most promising pieces are routed to local lapidaries who understand the nuances of Ceylon material, seeking to preserve weight while revealing the optimum color with sensitive planning. The cutting of this particular rough into a cushion with a mixed brilliant scheme was executed with the intention of maximizing face up color and dynamic light performance, while keeping a comfortable depth and spread. Subsequently the stone underwent a carefully monitored heat treatment to achieve an even and stable blue, followed by a fine polish that brings out crisp facet delineation. The sapphire then entered a protocol of documentation and photographic capture, accompanied by origin verification based on traceable supply chain practices, before arriving into our collection at The Natural Sapphire Company, ready to be offered to discerning buyers.

For collectors and those commissioning fine jewelry, this sapphire offers a compelling balance of natural character, technical quality, and responsible provenance. Its 1.60 carat weight and tidy 7.34 by 5.48 by 4.28 mm proportions make it an excellent candidate for a striking engagement ring, a classic three stone composition, or a refined pendant, and the medium intense Ceylon blue will complement both yellow and white precious metals. The very slightly included clarity means the gem reads clean to the eye while retaining natural inclusions that contribute to authenticity, and the excellent polish ensures top tier finishing. Because The Natural Sapphire Company emphasizes clarity of information and ethical sourcing, prospective buyers may request further documentation, detailed imagery, and independent laboratory reports to support evaluation and investment decisions. If you value a sapphire that combines historical provenance, measured technical merit, and artisanal finishing, this Ceylon cushion sapphire is a rare and practical choice, and our team is available to provide additional measurements, lighting comparisons, and mounting recommendations to help you realize its fullest potential.
