{"product_id":"amethyst-cluster-small","title":"Amethyst cluster small","description":"\u003cp\u003eThis natural amethyst cluster features a soft blend of pale lavender and near-clear quartz crystals, forming a compact and sparkling display piece. The crystal points are slightly larger and more defined than fine druzy, creating a textured surface that catches the light beautifully. Set on a natural quartz matrix, the piece retains its raw, organic shape with earthy tones along the outer edge.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eKey Features\u003cbr\u003eMaterial: Natural amethyst (quartz variety)\u003cbr\u003eFormation: Crystal cluster growth on quartz matrix\u003cbr\u003eColor: Pale lavender with areas of clear to milky quartz\u003cbr\u003eCrystal Habit: Medium crystal points with a glassy lustre\u003cbr\u003eFinish: Raw, natural formation with unpolished edges\u003cbr\u003eShape: Freeform natural cluster\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eDimensions\u003cbr\u003eApprox.

The lighter purple tones seen in this piece suggest lower iron content and more subtle natural irradiation during formation.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThis cluster displays well-formed crystal points that grew inward from the cavity walls, resulting in a layered, dimensional structure. Compared to finer druzy, these larger points create a more defined, geometric appearance while still maintaining a gentle sparkle.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe surrounding white to translucent quartz matrix and earthy outer layer reflect the host rock in which the amethyst formed.
