1.75 Ct. Blue Sapphire from Ceylon (Sri Lanka)

If you are searching for a singular sapphire that combines timeless beauty with honest provenance, this 1.75 carat cushion shape blue sapphire is designed to answer that search and to become the defining center of your most meaningful pieces, whether you are planning an engagement ring, building a collector grade cabinet of rare gemstones, or selecting a responsible investment with enduring appeal, The Natural Sapphire Company is proud to present a stone that meets those exact needs. This sapphire is transparent with a vivid color intensity that catches the eye the instant it is set into light, and its unenhanced origin from Ceylon Sri Lanka brings a rarity and authenticity that discerning buyers ask for. You want a gem that will carry stories and stand the test of style and time, and this sapphire delivers on those expectations with a natural, vivid presence, a clarity that reads as very very slightly included when viewed at eye level, and an excellent polish that maximizes its brilliance and table presence.

In practical terms this stone is 1.75 carats and cut to a comfortable cushion shape with dimensions of 7.12 by 5.53 by 4.85 millimeters, finished with a mixed brilliant cut that balances sparkle and depth, and it is entirely natural with no enhancement. Those details matter because they translate directly to what you will see on the finger or on display, and because unheated Ceylon stones of this quality are increasingly difficult to find. The mixed brilliant cut gives the sapphire dynamic light return from both the crown and pavilion facets, so it flashes lively scintillation while retaining the deep, saturated blue that defines its character. The very very slightly included clarity means that to the unaided eye the gem appears clean and lively, and because the polish is excellent you will notice crisp facet junctions and smooth reflective surfaces that enhance both color and brilliance.

When you compare this stone to famous sapphires in history you begin to understand its unique place in the market. The velvety depth of deep royal blues found in crown jewels evokes the Stuart Sapphire, while the luminous cornflower and vivid blue tones celebrated in the Logan Sapphire recall the best of Ceylon material, and the storied Kashmir sapphires are often praised for their sumptuous velour of tone, a quality that collectors still seek. This sapphire channels the bright, lively spirit of fine Sri Lankan stones like those that have adorned historic pieces, while offering a clarity and modern cut that create more immediate brilliance than many older, heavily included or cabochon stones. Unlike the famous star sapphires such as the Star of India which captivate with asterism but sit in a different collecting category, this gem offers transparent crystalline purity and a lively mixed brilliant cut that performs brilliantly in contemporary jewelry. Its unheated Ceylon origin gives it provenance and character, it is rare to find a vivid, unenhanced sapphire in this weight class with such a clean eye evaluation, and that combination is the reason collectors and committed buyers will recognize its distinct value.

For someone seeking the perfect setting, this sapphire excels in versatility as well as presence. The cushion outline offers a soft, romantic silhouette that sits beautifully within a halo engagement ring, in a three stone design, or as a solitaire with understated shoulders, and the mixed brilliant cut will dance under candlelight when paired with diamonds or warm accent stones. The dimensions make it an excellent center that balances visibility with wearability, suitable for both daily wear pieces and for special occasion creations. Because sapphires are durable and rated to withstand everyday use, this stone is an ideal choice for an engagement ring that must combine beauty with practicality. If you seek a bespoke expression, The Natural Sapphire Company can recommend settings that enhance the deep blue, such as warm rose gold for contrast or platinum for a cooler tone, and we can help with diamond accents that complement the gem without overpowering its natural color intensity.

Choosing this sapphire means choosing a gem that answers the emotional needs of commitment and the rational needs of provenance and longevity, and The Natural Sapphire Company stands behind every piece we offer with expertise and service. If you want a conversation about design ideas, certification options, or custom mounting that will protect and showcase this stone for generations, we are ready to assist, and we can discuss appraisal and care so the sapphire continues to reward your decision with daily wear and lasting beauty. For someone who is done searching and ready to secure a stone that combines the storied charm of historical blue sapphires with contemporary cutting and clarity, this 1.75 carat cushion Ceylon sapphire is a compelling, honest, and elegant solution.
