How do natural, laboratory-grown and imitation gemstones differ?

Answer

Direct answer

Natural gems form in nature; laboratory-grown gems are manufactured counterparts, while imitations resemble a gem but may be a different material.

Ask for the identity and origin category to be written clearly on the invoice rather than accepting terms such as original or American diamond. Appearance alone may not distinguish them. A competent laboratory can identify material within the scope of its report. These categories should be disclosed separately from cut, condition, treatment and price; none is explained by sparkle alone.
