Sirius Star® Octagon

The world’s brightest diamond®


The Sirius Star® Octagon features greater scintillation and increased light return, improved brilliance and higher visual appeal than any other octagonal shape.

Sirius Star® Octagon features 88 inclined facets (octagonal main facet design with four-tier pavilion). All the facets are indexed and inclined to present the maximum actual and virtual facet definition.

Sirius is the brightest star in our night sky, and was the standard star for the color white in ancient China. The ancient Greeks believed that Sirius’s appearances heralded the arrival of the hot and dry summer months. It was described as “flaming” in literature.
