1.68 Ct. Blue Sapphire from Ceylon (Sri Lanka)

If you are searching for a sapphire that ends your quest for the perfect center stone, this 1.68 carat cushion shape blue sapphire answers that need with confidence and poise, from The Natural Sapphire Company. The gem measures 7.45 x 6.34 x 3.82 mm, and is cut in a mixed brilliant style that balances lively scintillation with the flattering outline of a cushion shape. Its intense color intensity is immediately appealing, a vivid, traditional blue that reads as both regal and wearable, while an excellent polish ensures smooth, even reflection across each facet. The clarity is graded as slightly included when evaluated at eye level, which gives the stone character without distracting from its overall beauty. This sapphire has undergone a standard and stable heat treatment enhancement, a widely accepted practice that improves color and clarity, and its origin is Ceylon Sri Lanka, a source renowned for producing some of the world’s most admired blue sapphires.

For the conscious consumer who cares where a gem comes from, provenance and responsible sourcing are as important as beauty, and The Natural Sapphire Company makes that a priority at every step. We work directly with trusted partners and mining operations in Sri Lanka, and we invest in relationships that promote ethical labor practices and community development. Each sapphire in our collection is selected not only for its gem quality, but also for the integrity of its supply chain, with documentation and careful record keeping so you can feel confident about the stone you choose. Heat treatment is fully disclosed, because transparency is essential for buyers who want to understand the history of their gemstones. We also offer guidance on traceability and the specific steps taken to support fair working conditions and responsible environmental practices at origin, so that your purchase supports a better system for miners and their communities.

This cushion blue sapphire fits beautifully into the collection of someone who values both conscience and style, whether you envision it as the heart of an engagement ring, a signature pendant, or a collector’s showcase piece. The intense blue will complement both warm and cool metal choices, appearing strong and saturated in white gold or platinum, and taking on a richer, more classic feel in yellow gold. The stone’s mixed brilliant cut gives it everyday sparkle, while its pleasing proportions make it an excellent candidate for a variety of settings, from a low profile bezel for active wearers, to a halo or cathedral mount for someone who prefers visual drama. Slight inclusions tell the story of the stone, and many collectors and connoisseurs prize that natural character as part of a gem’s soul. If your goal is a responsible, elegant, and enduring centerpiece, this sapphire checks every box, combining measured rarity with versatile wearability.

We understand that choosing a sapphire is both an emotional decision and an investment, so we provide the support you need to feel comfortable and excited about your selection. Our gem specialists at The Natural Sapphire Company are available to supply additional images and videos, to discuss setting ideas, and to arrange viewing or secure shipping. We can also provide further gemological evaluation upon request, and we stand behind our sapphires with clear disclosure of enhancements, origin information, and assistance with appraisals if needed. For maintenance, gentle cleaning with warm soapy water and a soft brush will preserve its polish, and periodic professional checkups of any setting will protect the stone during everyday wear.
