This transparent 1.75 carat oval blue sapphire measures 7.22 x 6.26 x 4.86 mm, presenting a balanced, elegant outline that reads well for both solitaire and three stone designs. The cutter employed a mixed brilliant faceting scheme, combining a brilliant style crown with a precision modified pavilion to maximize both scintillation and color saturation. The mixed brilliant approach produces a play of triangular and kite shaped crown facets that yield crisp light return, while the pavilion geometry is tuned to concentrate blue chroma toward the table for strong face up presence. Measured proportions produce a depth proportion of approximately 72 percent, a slightly deeper profile that intensifies apparent color without sacrificing transparency. The stone exhibits medium color intensity, presenting a well balanced blue that is neither muted nor overly dark, and the excellent polish on all facet junctions enhances the stone's luster and optical contrast.
Clarity is graded as very slightly included, evaluated at eye level, and this level of clarity ensures an open, transparent appearance to the naked eye while retaining natural internal character. Inclusions are minor and are intentionally preserved by the cutter to retain weight and natural integrity, rather than eliminated through aggressive cutting that can compromise yield or produce a glassy, lifeless face up appearance. The cutter prioritized facet orientation, pavilion angles, and crown symmetry to optimize light return and mask any minor internal features, resulting in a stone that reads clean in hand while maintaining natural origin and structural soundness. The excellent polish and careful girdle finishing further contribute to durable geometry and secure seating in a setting, and the oval outline yields optimal finger coverage and light performance when set in both low and high profile mounts.
This sapphire is unheated, no enhancement, and originates from Africa, attributes that align with collectors who prioritize natural gem material and transparent treatment histories.

For the conscious consumer building a considered collection, this 1.75 carat oval offers a versatile, enduring investment in natural color. The medium color intensity and mixed brilliant cut allow the stone to perform well across metal choices, pairing with platinum or 18 karat white gold for a cool, contemporary palette, or with 18 karat yellow or rose gold to warm the presentation and emphasize classic elegance. Its size and transparency make it an excellent candidate for a centerpiece engagement ring, a bespoke pendant, or a heirloom commission where longevity and provenance matter. Our bench team can advise on orientation, setting type, and protective design elements to preserve the stone in daily wear while maximizing optical performance.
