Portuguese Cushion Diamond — Exceptional Faceting with Timeless Elegance

This Portuguese Cut Cushion Lab-Grown Diamond represents a rare expression of modern diamond craftsmanship. Combining the soft, romantic silhouette of a cushion cut with an intricate 161-facet Portuguese-inspired pattern, this diamond creates an extraordinary display of light and movement.

Traditional cushion diamonds are admired for their graceful rounded corners and vintage-inspired appeal. The Portuguese cut elevates this classic shape through additional facet complexity, producing a richer pattern of reflections and enhanced visual depth.

Designed for those who want a diamond that feels distinctive rather than conventional, this speciality cushion cut offers the perfect balance between timeless elegance and contemporary innovation.

Diamond Specifications

Ultra-Rare 161 Facets for Maximum Sparkle

The defining feature of this Portuguese Cushion Diamond is its exceptional 161-facet structure. Compared with traditional cushion cuts that commonly feature fewer facets, this advanced design creates a more intricate pathway for light to travel through the diamond.

The result is a refined display of brilliance, fire and scintillation that changes beautifully as the diamond moves. Each angle reveals new reflections, creating a lively and captivating appearance.

For buyers searching for a lab-grown diamond with a premium visual experience, Portuguese faceting provides a rare combination of craftsmanship, innovation and luxury appeal.
