Because the lattice structure packs the carbon atoms closer together in diamond than in any other substance.
Raw diamonds can be transparent, translucent or opaque, depending on their clarity. Gem-quality diamonds are transparent.
They can be either or both. Industrial diamonds are more translucent; jewelery-grade stones are transparent.
Yes, some gem-quality diamonds -- only about 20% of all diamonds mined -- can be considered transparent.
Not generally, in the sense that raw colourless stones are transparent.
Transparent
diamonds that are clear -- that are transparent.
Raw diamonds can be transparent, translucent or opaque, depending on their clarity. Gem-quality diamonds are transparent.
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

Gemstone diamonds of whatever colour are transparent.
Yes, some gem-quality diamonds -- only about 20% of all diamonds mined -- can be considered transparent.
Not generally, in the sense that raw colourless stones are transparent.
Gem-quality diamonds can be said to be transparent to translucent in rough crystals. Industrial diamonds are cloudy -- intensely flawed -- and may be opaque, but are not considered transparent.
One would describe a high-quality black diamond as translucent, not as transparent.
Depending on the individual diamond, it is transparent to translucent.
Uncut diamonds can be formed into pyramid-shaped stones, sometimes with the bottoms of two pyramids joined at the base. However, most uncut diamonds are irregular in their shape. Gem-quality stones are transparent and coloured raw diamonds are clearly coloured and transparent.
