Sapphiroid
An alternative term for corundumoid, suggestive of sapphire, which is a blue form of corundum. Early in history, and well into the Information Age, sapphires were a valuable and rare gem stone, and the name was considered more attractive because it implied value. Corundumoid was considered too suggestive of carborundum, an industrial material, and alternative names derived from other coloured forms of corundum, such as ruby, were less euphonious.
