5 Pieces Natural Ruby 4.61ct Untreated Rough Crystals

Five rough ruby crystals show a warm purplish-pink to pink-red coloring, each stone semi-transparent with the ruby hue glowing through the unpolished crystalline body. The pieces carry natural surface texture across irregular crystal faces, and the characteristic color of Madagascar corundum shifts between pink and a deeper berry-rose depending on the light direction. Each crystal has its own shape and internal pattern, reflecting the natural growth conditions of the mineral deposit.

Madagascar accounts for the majority of the world's commercial ruby supply, and these crystals come directly from the island's ruby-bearing regions as raw, untreated rough. No heat or other enhancement has been applied, preserving the stones exactly as extracted from the deposit. Semi-transparent rough rubies in this size range are popular for wire-wrap jewellery, raw gemstone collections, mineral specimen display, and crystal-form jewellery design. Strong natural fluorescence under UV light is also characteristic of Malagasy ruby corundum.
