While there are many options to choose from, two of the best black gemstones are black sapphire and black diamonds. Interestingly, not many people know that diamonds and sapphires can be found in black varieties.
If you’re looking for a black gemstone, these two offer the best options. But which should you choose – black sapphire or black diamond? Here’s a brief breakdown of the pros and cons of black sapphire vs. black diamond.
Black Diamond and Black Sapphire
Unlike their colorless and colored counterparts, both black diamonds and black sapphires have been considered inferior, low-grade gemstones and were not commonly used in jewelry. However, since the 1990s, black diamonds saw an unexpected surge in popularity, partly due to clever marketing tactics and expert designers who incorporated the gemstone into their work.
Black sapphires are not as prestigious as black diamonds. They are still considered second-rate gemstones and are not highly valued.
Black diamonds, also known as carbonado, contain graphite and amorphous carbon in their composition. They get their color from the presence of heavy amounts of graphite impurities within the stone. Natural black diamonds are very rare and mainly found in Central Africa and Brazil.
Black sapphires are made of corundum with inclusions causing the color of the stone. Unlike black diamonds, black sapphires are found in abundance, with most originating in Australia.
Black Diamond and Black Sapphire in Jewelry
Diamonds and sapphires are among the top gemstones for use in jewelry. This is because of their durability and appearance.
Black diamonds rank at 10 on the Mohs scale and are the toughest of all diamond varieties, due to their compact composition. The color of black diamonds is graded as Fancy Black and can range from faint gray to solid black. Evenly saturated black diamonds are the most sought-after. These stones are also quite lustrous and are often faceted for maximum effect. Black diamonds can be pricey depending on the quality of the stone, with some carats costing thousands of dollars.
Black sapphires, on the other hand, are very affordable. They have very good durability (9 Mohs) and wearability. As black sapphires are not brittle, they are not prone to breakage. Black sapphires are commonly solid black in color and seem to absorb all light that touches them. It does not reflect light and is not a lustrous stone. They are often faceted or cut en cabochon.
Both these gemstones are ideal for daily wear and will last a long time with minimal maintenance. White metal settings give a cool contrast to black gemstones and have a modern touch to them. For a more vintage, softer feel, yellow or rose gold is perfect.
Synthetic and Treated Black Diamond and Black Sapphire
Due to the high price tag of natural black diamonds, most black diamonds on the market are made by heat-treating low-quality colorless diamonds to turn them black. There are also synthetic black diamonds, which are man-made versions. These are exactly the same as natural stones.
Black sapphires may sometimes be heat treated to enhance their color. There are also synthetic versions of black star sapphires, which is a more expensive variety of black sapphires that contain asterism.
Should I Buy a Black Diamond or a Black Sapphire?
Both these gemstones have many advantages, making them very good choices for black gemstones. However, black sapphires are more affordable. Black diamonds, on the other hand, have more depth and brilliance and are also considered more prestigious.
If budget is your main concern, we recommend going with black sapphire. If, however, you’re looking for durability, then consider a black diamond.
