6.63 Ct. Blue Sapphire from Ceylon (Sri Lanka)

When you are searching for a sapphire that will end the quest for the perfect stone, you want clarity, color, and provenance all aligned in one exceptional gem. This stunning C.Dunaigre certified Blue sapphire answers that need with authority. At 6.63 carats, and measuring 11.47 x 9.34 x 5.77 mm, its cushion shape presents generous table and depth that promise a presence on the finger or in a display that is both substantial and refined. Its origin from Ceylon Sri Lanka brings with it a pedigree of classic sapphire beauty, and the fact that it is transparent with no enhancement reassures the buyer that what you see is the natural character and charm of the stone. For an engagement ring that must speak of commitment and taste, or for a collector seeking a rare, unaltered example of island provenance, this stone answers that precise desire.

From every angle the mixed brilliant cut and excellent polish transform light into color and sparkle, making the sapphire a living object that performs as you move. The cushion outline softens corners and allows the intense blue color to breathe and saturate the facets. The mixed brilliant cut blends broad facets on the crown with precision pavilion facets, so that when light enters the stone it disperses and returns as a lively combination of scintillation and deep color. Viewed face up, the table reveals a serene and intense blue that reads as regal and modern at once. From the girdle and side views, the depth and pavilion angles show off flashes of lighter cornflower tones and deeper velvety blue, giving the gem dimensionality that keeps the eye engaged. The polish is excellent, so each facet edge is crisply defined, allowing every plane to play its part in the stone’s visual symphony.

Clarity matters when you want a sapphire that will hold up to scrutiny every day and still reward close inspection. This sapphire is graded very slightly included at eye level, which for the discerning client means you enjoy a gem that is essentially eye clean while retaining natural growth features that testify to its origin. Those very slight inclusions do not interfere with the path of light, and they offer the assurance of natural formation without the veil of significant clouding. Because the stone is unenhanced and C.Dunaigre certified, you have independent verification of its natural state and the integrity of its color. The intense color intensity is what many buyers search for and rarely find in this weight class and shape without heat or other enhancement. The result is a gem that wears beautifully in a daily piece or that stands proud in a bespoke setting, offering both presence and practicality. For collectors, the combination of Ceylon origin, unenhanced status, and weight makes this sapphire a meaningful addition to a carefully curated cabinet.
