Bracelet with natural stones that look like emerald, amethyst, ruby and quartz

Good quality stretchy bracelet with crystal cross and several natural stones. Not sure what they are, but they look like purple amethyst, red ruby, green emerald and pale yellow quartz. Fits sizes 7 and smaller. In excellent condition. Some stones have unevenness and imperfections, as pictured. But this is expected for semiprecious natural stones.
