Raw Ruby Crystal Value Guide

This large, translucent raw ruby crystal from Mozambique represents the modern era of corundum mining, where East Africa has become a premier source for significant specimens. Its intense pinkish-red fluorescence and natural hexagonal structure make it a prized piece for both mineral collectors and lapidary artists.

What affects the value of Raw Ruby Crystal?

• The degree of translucency and internal clarity significantly impacts the $180-$200 price range.
• The intensity of the natural red saturation, driven by chromium levels, dictates market desirability.
• Overall carat weight and the preservation of the natural crystal faces enhance the specimen's collectible value.
• The strength of the fluorescent reaction under UV light serves as a key indicator of quality and origin.

How to Identify Raw Ruby Crystal?

• Check for a strong pinkish-red glow when exposed to long-wave ultraviolet light, indicating high chromium content.
• Observe the characteristic hexagonal crystal system and rhombohedral cleavage patterns typical of natural corundum.
• Verify the presence of silk or needle-like inclusions which are common in authentic Mozambique rough specimens.
• Test for a hardness of 9 on the Mohs scale, as rubies are second only to diamonds in durability.

History of Raw Ruby Crystal

Rubies are the red variety of the mineral corundum and have been revered as the King of Gemstones for millennia. Significant deposits were historically found in Burma, though African mines in countries like Mozambique and Madagascar have recently become primary sources for large rough specimens. Large crystals like this are often used for carving or cabochon cutting due to their opacity.
