This 4-carat crystal over a billion years ago. This specimen exhibits a dual-tonal distribution of nitrogen and natural crystal lattice distortion. Unlike standard monocrystalline structures, heart-shaped fancy color diamonds require precise facet geometry to prevent color concentration loss. It represents a geologically finite resource heavily favored by international wealth preservation funds.

Gemstones are not heated, keeping the original texture and fire color of diamonds. With GIA international authority certificate, authenticity and quality are guaranteed.
