Quartz Crystals is a package with 11 realistic crystal models. They are very detailed, with carefully sculpted, worn edges and corners, and custom UV and texture maps for each object. They represent raw crystals, or worn crystals you will find in mine and caves.

Each crystal has a 2048x2048 texture and 3 shader/texture types: Quartz, Amethyst and Cobalt. Each shader comes in a fast, and a version with refract (longer rendering times but better result)
