Light Blue Portuguese Oval Lab Sapphire

A 1.45 carat blue sapphire precision-cut in an intricate Portuguese oval design — a faceting style prized for its layered crown facets and extraordinary light return.

Grown using the Czochralski method, this lab-created sapphire exhibits exceptional clarity and structural purity, allowing the complex facet architecture to perform at its highest potential.

Its tone is a refined cool blue — shifting between cornflower and steel in changing light — with crisp contrast and remarkable internal bloom. The Portuguese design creates a floral, almost kaleidoscopic brilliance that radiates from the center outward.

Measuring 8.2 × 6.5 × 4 mm, the proportions offer elegant presence without excess depth, making it ideal for a sculptural ring or heirloom pendant.

Precision-cut in-house at Belliveau Atelier, this is engineered symmetry meeting artistic intent.

Not mass-produced sparkle.
