The stone exhibits a vivid pink hue with subtle magenta and fuchsia flashes. Its color appears evenly distributed throughout the stone, producing a consistent face up appearance without obvious zoning in the supplied imagery.

Under ultraviolet illumination, pronounced red-pink fluorescence provides a striking contrast to its appearance under ordinary lighting. This response is consistent with chromium-bearing corundum, although fluorescence alone cannot establish the precise growth process.

The stone displays exceptional transparency and an internally clean appearance, recorded as IF (Internally Flawless) in the inventory documentation.

The radiant cut combines clipped rectangular corners with brilliant-style faceting, creating a balance between geometric outline and lively light return. The approximately 1.27:1 length to width ratio gives the stone a broad rectangular profile suitable for both horizontal and vertical mounting orientations.

The reported 6.00 mm depth provides substantial material beneath the crown. Final light performance will also depend on facet angles, symmetry, lighting, and viewing orientation.

This gemstone is laboratory grown corundum rather than naturally formed sapphire. Its pink color is associated with the synthetic material itself, and conventional natural sapphire treatment terminology should not be applied without specific relevance to its manufacturing history.

With a Mohs hardness of 9, corundum is highly scratch resistant and well suited to jewelry intended for regular wear. Nevertheless, the cut corners and girdle should be protected against concentrated impacts.

Bezel and conventional prong settings are suitable options. Tension mounting requires a design specifically engineered for the stone and should not be assumed safe solely because of its hardness. Ultrasonic cleaning should follow the jeweler's assessment of the completed setting and any other materials incorporated into the piece.

The stone is recorded as laboratory-grown using the Czochralski method. This should be understood as the supplied inventory designation rather than independently verified growth method identification.

Laboratory grown corundum offers the optical and physical properties of corundum without the geological rarity associated with natural sapphire. Its value is principally determined by color, cut quality, size, clarity, manufacturing consistency, and the intended jewelry application.

This stone is best understood as a precision cut design material rather than a natural gemstone rarity.

Its strongest features are the vivid pink color, 4.04 carat size, internally flawless appearance, and carefully executed radiant faceting. The rectangular geometry lends itself particularly well to architectural jewelry, strong linear settings, contrasting metal finishes, and contemporary statement pieces.

For a designer interested in proportion, color, and controlled optical performance, the stone offers substantial creative flexibility without the acquisition cost associated with a comparable natural pink sapphire.

The laboratory grown identity and stated growth method are based on the supplied inventory record. Independent gemological examination may be arranged if formal verification is required for resale or documentation.

Every stone offered by the House is selected for more than nominal rarity. Color, proportion, clarity, cutting, material integrity, and the way a gemstone responds to light are considered together.

At Dante Bianco, a gemstone is not simply a measure of carat weight or a line on an inventory sheet. It is a material with its own optical character, physical structure, and potential within a considered design. Each stone is chosen for the qualities that make it worthy of attention and for the possibilities it presents to the collector who recognizes them.
