5 Pieces Natural Ruby 5.00ct Untreated Rough Crystals

Five rough ruby crystals lay out a rich spectrum of deep red to purplish-red tones, each piece showing the characteristic color of natural corundum through its semi-transparent, unpolished body. The raw surfaces catch the light across irregular crystalline planes, revealing inner color that shifts between warm crimson and deeper berry-red depending on viewing angle. Natural growth textures, minor surface inclusions, and the honest character of uncut stone give each crystal its own identity within the group.

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.
