How do I evaluate the value of a black sapphire?

The value of a black sapphire is based on several factors, though the most important ones are the formation and color of the gemstone.

Generally speaking, the darker the color, the better; and the more opaque and flawless the stone is, the greater its value will be. The presence of inclusions will lower its value, slightly depending on their size, visibility and number.

In terms of prices, sapphires can range from $25 to over $10,000 per carrot, and require visual analysis from an expert jeweler. Black sapphire is less expensive than black star sapphire, which is a rarer material only sourced in a few key parts of the world.

They are found in Sri Lanka, Madagascar, Tanzania and Nigeria the most often. Sri Lanka is by far the best location for finding them, and they have been mined there for many years.
