Rough Sapphire Value Guide

Rough Sapphire is a raw form of corundum prized since ancient times as the 'gem of the heavens' for its deep blue hue. These unpolished specimens are highly collectible due to their historical association with royalty and the ancient Persian belief that their reflection painted the sky blue.

What affects the value of Rough Sapphire?

• The intensity and saturation of the deep blue hue significantly impact the $150-$180 price range.
• Overall carat weight and the physical dimensions of the raw corundum specimen.
• The presence of internal inclusions or structural clarity within the unpolished stone.
• Historical provenance or specific geographic origin, though often unknown in raw trade.

How to Identify Rough Sapphire?

• Check for a hexagonal crystal structure characteristic of the corundum mineral family.
• Verify a high level of hardness, as sapphire ranks 9 on the Mohs scale, second only to diamond.
• Look for a naturally occurring deep blue color that remains consistent even in an unpolished, raw state.
• Examine the surface for a dull or greasy luster typical of unrefined, rough gemstones.
