The value of black onyx is determined by several factors, including quality, cut, weight, and overall market demand. A small, simply cut black onyx cabochon might be available for a few dollars, while a large, intricately carved piece or one with exceptional color saturation could command hundreds or even thousands of dollars. The presence of matrix, or other mineral inclusions, can sometimes affect the price, either positively or negatively, depending on the specific characteristics and the buyer’s preferences.
Historically prized for its protective and grounding properties, this gemstone has been used in jewelry and decorative objects for millennia. From ancient signet rings to contemporary pendants, its deep black hue lends an air of sophistication and elegance. The stone’s durability and relative affordability, compared to other gemstones, contribute to its continued popularity in modern jewelry design.
