WebA sapphire stone can always be re-cut, so clarity is probably more important. A top quality 1 to 2 carat stone might retail for prices between $800 - $1200 per carat. While quality 2 to 3 carat stones would sell for approximately double the price per carat, so that would be around $1600 - $2000 per carat. Webthe CTE increases with rising temperature. Thermal expansion of pure metals has been well characterized up to their melting points, but data for engineering alloys at very high temperatures may be limited. In general, CTE values for met-als fall between those of ceramics (lower values) and polymers (higher values). Common values
