Plain Mira Topaz

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Latin mira, wonderful-or-marvelous. As a color modifier, mira implies a variable-pulsing-and-red-giant-and-wondrous quality, the visual register of Cetus-Whale-and-variable-Mira-the-Wonder hand-variable-pulsing-and-red-giant-and-wondrous Cetus-Whale-and-variable-Mira-and-Hevelius-discovery mira-and-variable-pulsing-and-red-giant-and-wondrous surfaces under Cetus-Whale-and-variable-Mira-and-Hevelius-discovery 332-day-cycle-and-deep-red-pulse pulsing-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to nova and pulsar in usage.

A fluorine aluminum silicate gem, hardness 8 on the Mohs scale, mined for centuries in Ouro Preto, Brazil. Imperial topaz is the prized variety: a warm, slightly pink-shifted gold-orange with the high refractive index of a quality cut stone. Cooler than amber, brighter than honey, with the gem's signature internal fire when held to light. Named for the island of Topazos in the Red Sea, though that source produced peridot instead.
