Depending on the quality of the diamond, its transparency can be transparent to non-existent.
Diaphaneity -- a function of the way light interacts with the surface of a substance -- of diamond is transparent in gem-quality diamonds, translucent in sub-gem-quality stones, and opaque in industrial diamonds.About 80% of all diamonds mined are industrial diamonds.
Gem-quality diamonds -- only about 20% of all diamonds mined -- are transparent, some flawlessly transparent. A gem-stone diamond's transparency can range from transparent or sub-transparent to translucent. Industrial diamonds -- 75% of all diamonds mined -- are not transparent at all, but are even cloudy to dull. you can see through it if it is a gem-quality diamond

Diamonds are most useful in industrial applications, usually based on the mineral's supreme hardness. Transparency is one of the characteristics of gem-quality diamonds, which represent only 20% of all diamonds mined. From Wikipedia: "Specific gravity is the ratio of the density of a substance compared to the density (mass of the same unit volume) of a reference substance." You can read more about the specific gravity of gemstones, below. It explains how specific gravity is used to identify gemstones.
