💫 Golden lore and care
“Madeira Citrine” describes a rich orange-brown colour rather than a guaranteed origin. Many Citrine clusters and geodes are heat-treated Amethyst, while Ametrine contains naturally joined purple Amethyst and yellow Citrine zones within the same Quartz crystal.
Citrine measures 7 on the Mohs scale and has no cleavage, although it remains brittle enough to chip under a sharp impact. Clean it with warm water, mild soap and a soft brush. Avoid steam, sudden temperature changes and prolonged intense light, which may weaken the stone or alter some colours.
