Sugar Rainbow Amethyst Cluster

5*2cm About Rainbow Sugar Amethyst Rainbow Sugar Amethyst is a descriptive trade name used for amethyst and quartz specimens covered with extremely fine druzy crystals. These tiny crystals create a glittering, sugar like surface rather than the larger crystal points normally associated with traditional amethyst geodes. The subtle rainbow appearance results from natural variations within the quartz, agate matrix, mineral inclusions and surface coatings. Each specimen has its own distinctive combination of colour, texture and crystal formation. Uruguay is highly regarded for its amethyst deposits, known for compact crystal formations, attractive agate borders and richly coloured interiors.
