Buyer Beware
Black Gemstones Buyer Beware Guidelines
Black gemstones are rare and are desired by gem buyers and jewelers. Therefore, it becomes important to check the authenticity of Black gemstones before buying.
The price of Black gemstones does not increase based on size and weight. There are other quality combinations including origin, color, clarity, cut, shape, rarity, carat weight, certification, and treatment which determine the price of Black gemstones. A buyer needs to understand that the weight of Black gemstones in India is usually expressed in Ratti and not in Carat. A buyer must understand the difference between Ratti and Carat. (1 Ratti = 0.91 carat)
There are various enhancements or treatments used to alter and darken the color, improve the appearance and the clarity of Black gemstones. Black gemstone like Black Onyx is commonly dyed or stained to alter the color and irradiated to darken the color of Black Onyx gemstone. Black Pearl or Tahitian Pearl is often dyed to add color and bleached to create more even color or lighten whereas some specimens of Black Pearl or Tahitian Pearl are not known to be treated. Whereas, Black Spinel, Obsidian, and Schorl Tourmaline are not known to be treated or enhanced. If buyers see any enhancements or treatments on the Black gemstone, then they can ask for a genuine report from the Gemological Laboratory. The Lab certifications determine the authenticity of the Black gemstone. Customers should be able to distinguish between real and fake Gem Lab Certifications and always verify the physical characteristics of the Black gemstone from Gem Experts and Astrologers. To identify the authenticity of the Black gemstone, the customer can cross-check the report number on the Gem Lab certificate from the Gem Lab website or the company lab. If both the report numbers are alike, then it is an authentic Black gemstone certification.
