➡️ Technical specifications

"Solar Bastion" is an impressive, 3,118 ct untreated sapphire, precisely cut into a striking octagonal step cut. This cut frames one of the rarest color phenomena in basaltic sapphires: an intense, sun-like yellow-to-green flare that floats like a glowing core within the crystal. The rectilinear facets act as a transparent window, directing light in vertical flashes through the golden center, while the green peripheral zones dynamically shift with every viewing angle.

Despite the powerful internal color dynamics, the gemstone remains exceptionally transparent – a typical quality characteristic of high-quality, untreated basaltic corundums. The entire stone behaves like a precise light-prism body, whose defined facets create clear, brilliant reflections and convey an almost architectural order.

Confirmed as untreated by Bellerophon Gemlab, Solar Bastion combines weight, clarity, geometric elegance, and dramatic natural color in a sapphire of true collector relevance – a centerpiece stone for connoisseurs seeking the perfect fusion of structure, natural phenomenon, and premium cut.
