Which term refers to a wavy or bumpy area on the surface of a polished diamond?

• A. London Diamond Syndicate
• B. Lot price
• C. Lizard Skin
• D. Macle

Answer: (C)

That wavy or bumpy area on a polished diamond is called lizard skin. It describes a surface texture that looks like the pattern of reptile skin—irregular ridges and valleys across the facets. This feature is about the diamond’s surface finish, not about inclusions, weights, or market terms, and it’s something that can be seen under magnification or in certain lighting conditions. The other terms refer to completely different ideas—one is not a standard diamond term, another is a pricing/auction concept, and the last describes a small twin crystal, not a surface texture.
