Rose quartz is a massive variety of quartz, meaning it forms in solid lumps rather than the pointed crystals amethyst is known for, which is why so much of it is carved rather than left natural. The pink comes from microscopic fibres of a mineral related to dumortierite, and strong sunlight will fade it over months, so a shelf out of direct light suits it best. At 7 on the Mohs scale it is hard-wearing and takes a high polish. Pick a shape from the row at the top to see just those. Hand-picked in St Andrews and posted UK-wide.
