What is the highest clarity grade for colored stones?

The highest clarity grade for colored stones is classified as eye-clean. This term indicates that the stone has no visible inclusions or blemishes when viewed with the naked eye, making it highly desirable in the marketplace. Eye-clean stones can show minor inclusions that are only detectable under magnification, but they do not detract from the overall appearance of the gem at regular viewing distances.

Clarity is a significant consideration for colored stones, as it not only affects the overall visual appeal but also influences the value. Gemstones that are eye-clean can have a higher price point than those with visible flaws since they are more aesthetically pleasing and rare.

While flawless is an ideal grade often used for diamonds, it is less common in the colored stone market. Heavily included and very slightly included describe levels of clarity that typically represent stones with more noticeable internal characteristics, which may significantly impact their beauty and value. Thus, eye-clean stands out as the best clarity designation for colored stones.
