1.72 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.72 carat emerald cut blue sapphire from Ceylon is a rare combination of precise proportions, vivid color, and uncompromised natural origin, dimensions 8.04 by 5.25 by 3.88 millimeters, clarity graded very slightly included at eye level, intense color intensity, and an excellent polish, no enhancement. The emerald cut, with its long table and broad step facets, presents a sophisticated, architectural elegance that allows the intense Ceylon blue to read consistently across the surface, without the visual noise that can come from smaller facet patterns. Because it is untreated, this sapphire shows a pure, natural hue that collectors and bespoke designers prize, and because the clarity is very slightly included to the eye, the gem retains a high degree of transparency and light return that only the best rough material can provide. The excellent polish amplifies the clean faceting, producing crisp facet junctions and a refined sparkle, and the overall finishing quality makes this stone immediately suitable for high level custom work, where every millimeter of cut and surface treatment matters.

Compared to more common cuts and sizes on the market, the emerald cut offers distinct advantages for custom jewelry design. Unlike brilliant cuts that emphasize scintillation, the elongated step facets of an emerald cut emphasize color depth and clarity, making this 1.72 carat stone appear larger table face to the eye than many round or oval stones of similar weight. Its rectangular outline with well balanced length to width proportions lends itself to a wide variety of settings, from classic four prong solitaires to sleek bezel mounts, from vintage inspired three stone rings to modern east west designs. The relatively shallow depth captured in the 3.88 millimeter pavilion height translates into a broad table, creating the visual impression of a substantial center stone without the metal weight or finger dominance that sometimes accompanies heavier gems. For designers who want a statement that remains elegant and wearable, this sapphire bridges presence and restraint better than many alternatives, especially for clients who prefer clean lines and directional sparkle.

When you compare this untreated Ceylon sapphire against the bulk of market options, several clear distinctions emerge. Many sapphires at similar price points have been heat treated to improve color and clarity, which is an accepted practice in the trade, however untreated stones are intrinsically rarer, and this one combines that rarity with an intensity of color that rivals treated material while maintaining natural integrity. Compared to stones from other origins, Ceylon sapphires often deliver a lively, vibrant blue that sits between the velvety depth of Burmese material and the ultradeep cornflower tones associated with Kashmir, making them versatile when paired with warm or cool metal tones. The very slightly included clarity is a practical advantage over heavily included stones, because it maintains visual purity in simple, open settings where step facets could otherwise reveal internal features, and the excellent polish ensures predictable behavior under different lighting conditions, which is a critical factor for bespoke designers seeking consistent appearance in day to day wear.

For customers and designers working with The Natural Sapphire Company this emerald cut blue sapphire is an ideal candidate for custom commissions, because its dimensions and profile are straightforward for setting, and because its natural, untreated status simplifies disclosure and design storytelling. The stone suits engagement rings where a clean, architectural aesthetic is desired, it works beautifully as a pendant centerpiece where the rectangular table captures and reflects light directly to the eye, and it can anchor asymmetric or mixed gem designs without competing visually with accent diamonds. Practical considerations such as setting depth, prong placement, and bezel thickness are easier to predict with this gem, given its precise dimensions, and its durability as corundum means it will withstand everyday wear better than many alternative colored stones. Choosing this sapphire through The Natural Sapphire Company ensures access to experienced gemologists and setters who understand how to maximize the stone s visual potential while preserving its natural character, making it a superior choice for custom pieces that demand both beauty and provenance.
