If the dome is oriented in between these two directions, an 'off-center' star will be visible, offset away from the high point of the dome. Unlike localized ("intra-atomic") absorption of light which causes color for chromium and vanadium impurities, blue color in sapphires comes from intervalence charge transfer, which is the transfer of an electron from one transition-metal ion to another via the conduction or valence band. The boules are sliced up into the desired window thickness and … Sapphire glass is an application of synthetic sapphire generally produced by subjecting aluminum oxide powder under extreme heat and pressure. This is created in the glass as it cools. It is typically blue, but natural "fancy" sapphires also occur in yellow, purple, orange, and green colors; "parti sapphires" show two or more colors. These are then cut with diamond saws, grinded and polished to the finished “glass” product. The inclusions can alternatively produce a "cat's eye" effect if the girdle plane of the cabochon is oriented parallel to the crystal's c-axis rather than perpendicular to it. The use of sapphire significantly reduces the cost, because it has about one-seventh the cost of germanium. [14] The stones are cut en cabochon, typically with the center of the star near the top of the dome.
