Natural Sri Lankan Sapphire — 3.31 Carat Oval Cut

This is a natural, heated sapphire from Sri Lanka, weighing 3.31 carats in an oval faceted cut with VS clarity. Its cut is proportioned slightly deep, which concentrates a rich, saturated blue toward the center of the stone rather than spreading lighter tone toward the edges — a look cutters often favor for mid-size Ceylon stones. At 9.75 × 7.20 × 5.31mm, it's a substantial but wearable size for a ring centerpiece.

At a Glance

About This Stone

Sri Lanka has produced fine sapphire for centuries. At 3.31 carats, this particular stone sits at the upper end of what most buyers consider an everyday statement size — large enough to anchor a ring on its own, without needing a custom mount to accommodate it. Its slightly deep proportions are a deliberate cutting choice: rather than maximizing spread (the stone's face-up width relative to its weight), the cutter prioritized color depth, which is what gives this particular stone its concentrated center tone. That tradeoff means the stone reads slightly smaller face-up than a shallower-cut sapphire of the same weight would, but with noticeably richer color saturation across the middle of the stone. For buyers who want depth of color over maximum spread, this is the more desirable of the two tradeoffs.

Color and Light Performance

This sapphire shows a medium-to-deep cornflower blue with even saturation across most of the stone, deepening slightly toward the center where the pavilion's extra depth concentrates tone. Under direct light, it returns strong brilliance from the crown facets, with scintillation (the sparkle pattern as the stone or viewer moves) that stays lively despite the deeper cut — a sign the faceting was well executed rather than simply cut deep for weight retention. There's no visible color zoning across the face of the stone.

Cut Quality Notes

The oval outline is symmetrical, with facets that meet cleanly at the girdle and a polish free of visible drag lines or pitting. The extra pavilion depth was a deliberate choice to concentrate color rather than a byproduct of preserving rough weight — the proportions are even on both sides of the stone's length, not lopsided in a way that would suggest weight retention over aesthetics.

How This Stone Compares

Against typical 3-carat-class Ceylon sapphires, this stone's clarity (VS) and even color are both solidly above what's common at this size; many stones in this weight range show more visible silk or noticeable color zoning even after heating. What sets it apart from a higher grade, unheated stone isn't quality so much as treatment status — heated material like this is priced well below unheated sapphire of comparable color and clarity, which is part of why it remains an accessible way to get strong color and clean clarity at over 3 carats.

Sizing and Setting Guidance

Stones in the 2–4 carat range, like this one, typically suit a solitaire, halo, or three-stone setting and sit comfortably on most hand sizes without requiring a custom-sized band. At a depth of 5.31mm, this stone will sit at a medium profile in a standard prong or bezel setting — not flush against the finger, but not unusually tall either. Given its color-forward cut, a simpler setting with an open gallery (rather than a closed-back mount) will let more light reach the pavilion and support the stone's brilliance rather than working against it.

Treatment and Certification

This sapphire has been heat-treated, a longstanding, widely accepted, and permanent enhancement used on the majority of fine sapphire sold today. It's disclosed here and on request certification. For a full explanation of what heating does and why it doesn't reduce durability, see our treatment guide. Certification confirming natural origin and treatment status is available for this stone on request.

Care

Sapphire is hard enough (9 on the Mohs scale) for daily wear with minimal special care — clean with warm water, mild soap, and a soft brush. See our full gemstone care guide for cleaning methods and storage tips.

Frequently Asked Questions

Will This Stone's Depth Sit High on the Finger?

At 5.31mm deep, this stone will sit at a medium profile in most standard prong or bezel settings — not flush, but not unusually tall either.

Is VS Clarity Noticeable at This Size?

At 3.31 carats, VS inclusions are typically only visible under magnification, not to the naked eye at normal viewing distance.

How Does This Stone Compare to Unheated Sapphire of Similar Quality?

Its color and clarity are comparable to what you'd see in a good unheated stone, but because it's heated, it's priced well below unheated sapphire of similar visual quality — making it a way to get strong color and clean clarity at over 3 carats without paying unheated-stone prices.
