Abstract
Disclosed herein are coated gemstones, coatings for gemstones, methods of coating gemstones, and methods of using coatings on gemstones to avoid blemishes on gemstones. In some embodiments, diamonds are functionalized with anchor molecules that bind hydrophilic cyclodextrin molecules to confer hydrophilicity on the diamond. In some embodiments, the diamonds resist dirt and grime build-up.

A coated gemstone comprising a coating and a gemstone, the coated gemstone represented by Formula I:
- where
- G represents the gemstone and the coating comprises -A(—X)m;
- A is an anchor moiety covalently bonded to G;
- X is a guest moiety covalently bonded to A and configured to bind to a host molecule;
- m is an integer between 1 and 5;
- and
- wherein the coated gemstone is configured to resist the accumulation of oil and dirt on the surface of the gemstone when functionalized with the host.
