ℹ️
Resin Fill Present
Like most Brazilian quartzites, Crytos may contain polyester resin fill to stabilize the stone. In areas with significant direct sunlight, the resin can gradually yellow over time. Ask your supplier about the type of resin used — UV-stable epoxy resin is less prone to yellowing than standard polyester resin.
