Gem Quartz Stone

Umbrella-term gem quartz gemstones encompass amethyst, rose quartz, smoky quartz, and more, giving merchants a single category page that attracts wide-net searches like “natural quartz gems.” At 7 Mohs with no cleavage, quartz resists daily abrasions, a selling point for customers prioritising longevity without premium price tags. Because the mineral crystallises in sizeable geodes, lapidaries can supply oversized gem quartz stones—think 20 mm checkerboard ovals—that function as dramatic focal pieces while staying budget-friendly. Offer educational content on colour origins (iron for amethyst, titanium for rose), and you simultaneously engage hobbyists and buyers looking for metaphysical properties, increasing dwell time and conversion probability.
