Cal's Extra Gems
Cal's Extra Gems adds several new gem ores, two armor and tool sets, and more than 90 new blocks to Forge worlds on 1.20.1.
What it does
The gems are sapphire, opal, topaz, beryl (including aquamarine), quartz and six tourmaline colors. Each one generates in a set of biomes or height bands, and quartz appears throughout the Nether. Sapphire sits low in the world, topaz and opal lie in mid-depth bands, and beryl is found both lower and higher up. Tourmaline is spread across forest, savanna, jungle, taiga and hill biomes. The mod also adds extra quartz colors and emerald slabs and walls.
The additions are mostly decorative and crafting-related: the mod includes two new armor and tool sets built from the gems, and the total count of new blocks exceeds 90. Installation covers the server and each player's game. It is published for Forge only, and the only game version covered is 1.20.1, with the latest file, 1.2.1, dated 2025-10-01.
