Mama's Marvelous Minerals

Mama's Marvelous Minerals contains the Gemstone content which used to be in Mama's Marvelous Materials. There have been changes, though:

•  Gems are not in ores now, they are in Geodes.
• Geodes contain Gem Blocks and buds/clusters, same as Vanilla Amethyst.
• Gem Tiles have been retextured, and can be crafted with a Stonecutter. 
• Armor has been added to the game for every Gemstone, along with 3 bonus "Ancient" armors.
• Gemstone armors have a single potion effect "set bonus" applied when wearing all 4 pieces. The bonus is different for each set of armor.
• Ancient Armors are created by locating ancient scraps and reviving them with aggregates made from gems and eyes of ender.
• Ancient Armors have a 'set bonus' which consists of 4 diffferent potion effects, depending on the type of armor.
