Attestations from sources in English:

Tehuilotl (glass, crystal) can come in various colors, and therefore it will appear in compound words such as this one for amethyst. Book 11, f. 206v, of the Florentine Codex has a discussion of this. One type of amethyst, apparently with a red tone, is called tlapaltehuilotl.
