独特的天然黄水晶色调簇状石英晶洞，内含玉髓和簇状晶晶体。高品质！ 水晶矩晶体 - 高度: 30 cm - 宽度: 12 cm- 3.2 g

天然晶簇石英晶洞，内含玉髓和晶簇晶体。\nDruzy Quartz: Coverage on the interior surface by tiny, sparkling crystal points known as “druzy.” In Brazilian specimens, this is frequently quartz.\n晶簇石英：覆盖内表面的微小闪亮晶尖被称为“晶簇”。在巴西标本中，这通常是石英。\nChalcedony/Agate Base: The more solid, light-colored material forming the structure is likely chalcedony or agate, which are common host materials for these crystal formations in Brazil.\n玉髓/玛瑙底基：构成结构的更致密、浅色材料很可能是玉髓或玛瑙，它们是巴西此类晶体形态常见的母岩。\nPotential Citrine Tint: The yellowish-tan color of some crystals suggests it could be a light variety of citrine, which is very common in Brazil and often forms in these geode-like structures.\n可能的黄褐色影调：部分晶体呈现黄褐色，可能是淡黄水晶（黄水晶）的变种，这在巴西非常常见，且常在这种类似晶洞的结构中形成。\nGeode Structure: The image shows a hollowed-out or "cave" formation typical of a geode, where minerals have precipitated inside a rock cavity.\n晶洞结构：图像显示的是典型的空心“洞穴”形态的晶洞，矿物在岩石腔内沉淀形成。\nBrazil is a world-renowned source for these types of mineral specimens, particularly from regions like Rio Grande do Sul.\n巴西是这类矿物标本的世界知名来源，特别是来自南里约格兰德州等地区。
