0.81 Ct. Blue Sapphire from Ceylon (Sri Lanka)

If you are searching for a rare and beautiful center stone that combines classic elegance with everyday durability, this 0.81 carat Ceylon blue sapphire is designed to end your search. Many clients come to The Natural Sapphire Company seeking a gem that will carry both emotional weight and practical longevity, whether for an engagement ring, a special anniversary piece, or a collector seeking a distinct example of Sri Lankan gemological character. This oval shaped sapphire offers an immediate visual appeal through its transparent clarity and medium intense blue color, and it also gives you the confidence of a gem that is cut and finished to perform in the jewelry you will wear most often. I will walk you through the exact details that make this sapphire a perfect solution for those who want beauty, character, and resilience in a single stone.

This sapphire weighs 0.81 carat, and its dimensions are 6.79 x 4.88 x 3.09 mm, a size that reads comfortably on the finger while maintaining a refined and wearable profile. The gemstone has been fashioned into an elegant oval shape with a mixed brilliant cut, a cutting style that balances lively top facet brilliance with attractive pavilion faceting that returns color to the eye. The polish is graded excellent, which means the surface facets are smooth and well finished to maximize light reflection and to complement the stone s clarity and color. The clarity grade is described as very very slightly included evaluated at eye level, which indicates a high degree of transparency and minimal internal features when viewed without magnification, preserving the clean, bright impression you want in a center stone.

Color is often the deciding factor when selecting a sapphire, and this stone presents a medium intense blue that is very true to the classic Ceylon palette. Ceylon sapphires from Sri Lanka are renowned for their lively, often cornflower influenced blues that present brightness and a pleasing balance between tone and saturation. This sapphire s medium intense color sits in that desirable window where the stone reads as distinctly blue without feeling too dark, which keeps the gem versatile for many metal colors and setting styles. The stone is transparent, which allows the mixed brilliant cut to express scintillation and sparkle, and the excellent polish ensures each facet catches and returns light effectively. The sapphire has been heat treated, which is a common and accepted enhancement that improves tone and clarity in natural sapphires, and when performed properly as in this instance it enhances the stone s natural beauty while remaining stable under normal wear conditions.

Durability is a practical concern for every piece of fine jewelry, and sapphires are among the best choices for daily wear, particularly for an engagement ring. Sapphire is a corundum mineral, and on the Mohs hardness scale it rates at 9, making it one of the hardest natural gemstones available and second only to diamond which is a 10 on the same scale. By comparison, common gemstones such as quartz rate around 7 on the Mohs scale, so this sapphire is significantly more resistant to scratches and wear than many other stones. That high hardness, combined with the excellent polish and the mixed brilliant cut which disperses impact across many facets, gives you a gem that not only looks luminous but also stands up to the routines of daily life. For additional protection and longevity I recommend design choices such as a protective bezel setting or secure claws with a low profile for active wearers, and routine care that avoids harsh chemicals and high heat beyond normal household temperatures.

At The Natural Sapphire Company we understand that selecting a sapphire is both an emotional and a technical decision, and this 0.81 carat Ceylon blue sapphire answers both sides of that process. The stone s proportions and mixed brilliant cut create a flattering face up appearance on the finger as shown in our reference images, while the medium intense blue color communicates a refined presence that suits both modern and vintage inspired settings. The clarity described as very very slightly included evaluated at eye level assures you that the gem will read bright and clear in most lighting, making it an excellent choice for a focal gem in a bespoke ring, a pendant, or a collector s cabinet. If you desire further customization, our team can advise on specific settings that enhance the stone s blue tone and protect the pavilion, and we can provide mounting suggestions that preserve value and aesthetics over a lifetime of wear.

This sapphire is a true representation of why collectors and couples favor Sri Lankan stones for pieces meant to last, and The Natural Sapphire Company stands behind the gem s origin and treatment disclosures. If your priority is a sapphire that brings together classic Ceylon color, responsible enhancement through heat treatment, precise cutting and finishing, and the durability of corundum with a Mohs hardness of 9, then this 0.81 carat oval blue sapphire fits that brief exceptionally well. I am available to assist with ring design ideas, metal and setting choices that will complement the gem, and to answer any technical questions you have about care and maintenance, ensuring that your selection not only meets but exceeds your expectations for beauty and practicality.
