Minecraft should have new ores such as Ruby, Sapphire, Copper, and Crystal. Ruby would be 60% better than iron and spawn in groups of 4 5 or 6. Sapphire would be 30% better than diamond and spawn in groups of 5 or 6. Copper would be 90% better than leather and spawn in groups of 3 or 4 or 5. And crystals would be 2x better than diamond and spawn in groups of 2 or 3. Ruby would be located at level 5-50. Sapphire would be located by lava. Copper would be located 5-61. Crystal would be very very rare, It could only be located 5-13. All of the Ores are have to be smelted. Ruby would be a diamond shape but red. Sapphire would be a dark blue ingot. Copper would be a color of brown. And crystal would be in the shape of a diamond buy a slightly lighter shade of diamond and a sparkle detail to it. I think adding these ore into Minecraft would be a good idea because finding the same old ores could be boring.
