Natural gemstones are mined from the earth, while synthetic (lab-created) gemstones have the same crystal structure and chemical composition but are grown in a laboratory.

The Four Cs are the universal standard for grading gemstones: color, clarity, cut, and carat weight. These factors determine a gemstone’s overall quality and value.

Reputable sellers should disclose any treatments, such as heat, radiation, or oiling, used to enhance a gemstone’s color or clarity. You can specify that untreated stones are often more valuable.

Provide information on the origin of your gemstones. This is especially important for customers who care about ethically sourced stones or believe that origin affects quality

Explain that all your gemstones come with a certificate of authenticity from a trusted third-party gemological laboratory, such as GIA, IGI, or GRS.
