![]() Diamond is the ultimate gemstone, having few weaknesses and many strengths Diamond is the ultimate gemstone in several ways: 1-Hardness: Diamond is a perfect "10", simply one the hardest substances known by a wide margin. Nothing can scratch a diamond other than another diamond or one of the few harder compounds. And a diamond can scratch alomost anything, even a sapphire. 2-Clarity: Pure diamond is completely colorless and transparent over a larger range of wavelengths (from the ultraviolet into the far infrared) than is any other solid or liquid substance - nothing else even comes close. 3-Thermal Conductivity: Diamond conducts heat better than anything - five times better than the second best element, Silver! This characteristic is the basis for "diamond tests", as it is simple and cannot be faked. 4-Refraction: Diamond has a relatively high index of refraction (ability to bend light), which gives it the high luster called adamantine. 5-Dispersion: Diamond has a relatively high optical dispersion which gives diamond the "fire" that makes it so desirable.
