{"product_id":"moss-agate-white-green-orange-79372","title":"Moss Agate | White, Green \u0026 Orange Dendritic Cabochon | 30x26 Rectangle | AG327","description":"\u003cp\u003eMoss Agate is a variety of chalcedony — a microcrystalline form of quartz — characterized by its distinctive dendritic inclusions of iron and manganese oxides that create moss-like, botanical, and landscape patterns suspended within a translucent to transparent host. Despite its name, moss agate contains no organic material; the plant-like formations are entirely mineral in origin, making each stone a completely unique geological composition that cannot be replicated. What makes this particular specimen exceptional is the rare combination of both green and orange dendritic inclusions against a clean white base — green dendrites driven by iron and manganese oxides, and warm orange formations produced by iron oxide concentrations that settled and crystallized in a distinctly different pattern within the same host material, creating a naturally occurring two-tone botanical composition of extraordinary visual complexity.\u003c\/p\u003e\n\u003cp\u003eThis large rectangle cabochon measures 30 x 26 x 4mm and weighs 27.7 carats — a substantial, statement-scale stone with a broad, open face that displays the full sweep of the dendritic patterning across an impressive canvas. The smooth polished surface and flat profile of just 4mm depth make it exceptionally versatile for setting, sitting naturally in a wide bezel without excessive height, and the rectangular silhouette gives it a bold, architectural quality that suits contemporary, mixed-media, and statement jewelry design equally well. At this size, the green and orange moss compositions read as a complete landscape scene — the kind of natural artistry that makes moss agate compelling to designers and collectors who treat their stones as wearable natural art. A stone of this face size, weight, and dual-color dendritic complexity is a rare find in any source material and represents an exceptional centerpiece opportunity for a bold cuff, oversized pendant, or statement brooch.\u003c\/p\u003e\n\u003cp\u003eDETAILS\u003cbr\u003e\nOrigin: Unknown\u003cbr\u003e\nSpecies: Quartz\u003cbr\u003e\nVariety: Moss Agate (Chalcedony)\u003cbr\u003e\nCut: Rectangle Cabochon, Smooth Polish\u003cbr\u003e\nSize: 30 x 26 x 4mm\u003cbr\u003e\nWeight: 27.7 ct\u003cbr\u003e\nSold: Individually\u003cbr\u003e\nTreatment: None\u003cbr\u003e\nHardness: 6.5 – 7 (Mohs)\u003cbr\u003e\nRefractive Index: 1.530 – 1.540\u003c\/p\u003e","brand":"Gem Enthusiast","offers":[{"title":"Default Title","offer_id":47671345512635,"sku":"AG327","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8214\/1627\/files\/moss-agate-white-green-orange-dendritic-cabochon-30x26-rectangle-ag327-2070648.jpg?v=1775630651","url":"https:\/\/gementhusiast.shop\/products\/moss-agate-white-green-orange-79372","provider":"Gem Enthusiast","version":"1.0","type":"link"}
