Opaque

Opaque refers to a material that does not allow light to pass through, resulting in no visibility through the object.

Part of speech: adjective
Definition: In the context of jewelry, an opaque gemstone is one that is completely non-transparent and does not allow any light to pass through, even when held up to a light source. This quality differentiates opaque stones from translucent or transparent ones, which can either allow light to pass diffusely or clearly through them. Opaque stones are valued for their rich color and texture rather than their brilliance or clarity. Examples include opal, turquoise, and jade, which are often prized for their aesthetic appeal and vibrant coloration. These stones are commonly used in various types of jewelry, including rings, pendants, and bracelets, where their unique appearance can be showcased.
