LHIndependentGem
LHIndependentGem is a designation applied to certain precious or semi-precious stones that meet specific grading criteria for color saturation, clarity, and cut. The "LH" prefix is often associated with a particular grading laboratory or issuer of certificates, though the exact meaning can vary depending on the context. The term "Independent" suggests that the gem has been evaluated by a third party, separate from the seller, to provide an objective assessment of its quality. "Gem" simply indicates that the stone is considered valuable and suitable for use in jewelry or as a collector's item.
When a gemstone is labeled LHIndependentGem, it implies that it has undergone a professional appraisal process.
