来自 Turritella-Achat / fossilem Schneckenstein 的自然自由形状 – 发现区域：印度尼西亚- 685.23 g

这块非同寻常的自由形态展现出惊人的化石结构密度，仿佛冻住的远古生命瞬间。整个表面上延展着精巧的螺旋状化石以及弯曲的碎片线，共同构成一个迷人的装饰性总体景观。化石呈现出明亮的奶油色和米色，与细致纹理的灰绿色至沙色基岩形成鲜明对比。\n\n尤其引人注目的是化石的自然分布：有些看起来完全完好，另一些则是被截断的螺旋或 elongated 段，形成一个生动、几乎是图形性的纹理图案。通过精心打磨，这一细致的化石结构得以充分展现，赋予自由形态一种宁静而又极具张力的气质。\n\nTurritella-Achat（或古生代螺螺石）被视为经典的化石珠宝与收藏石之一。然而，具有如此高密度化石与清晰纹路的标本相对罕见，具有独特的装饰性与收藏价值。\n\n作为陈列件，这块自由形态展现出强烈的存在感。不同视角会显现出新的细节、小螺旋、线条以及自然包裹的杂质，揭示这块石头的古生物起源史。中药学中传统上认为化石材料具有地定、稳定的作用——一种宁静、与自然相连接的能量，与这件作品的原始美学高度和谐。\n\nStone: Turitella Achat\nWeight: 685,23 g\nSize: 128x110x35mm\nTreatment: None\nOrigin: USA\n\nIt is a fossil wood dating back 200 million years, all parts from a log or branches have been silicified, meaning that organic components were little by little replaced by silicon in the form of jasper, chalcedony and more rarely opal. Without the organic parts, all the living matter was replaced by stone : there are growth rings, cell separations, almost like worm cracks.\nIts features are those of the mineral that would have pseudo-transformed the wood : the silicon.\nAnd that’s what we call a "petrified wood" in the common language.\n\nThe disclaimer about the healing properties\nas previously given :\nIt is believed that certain gemstones and minerals have beneficial health and spiritual properties.\nWe und Catawiki cannot guarantee or be held liable for these suggested attributes which have no scientific\nevidence and cannot be considered a substitute for traditional medical treatment.
