珊瑚玉怎么区分天然和非天然？珊瑚玉科普在漫长的保存反应期间，原始珊瑚骨骼里的碳酸钙成分，与含二氧化硅的火山岩流体产生化学置换反应。 地球化学研究文献里，已经记录了铜，铁，锌和银，与二氧化硅在热液中沉积的情况。During preservation the original calcium carbonate of the coral skeletons reacted with silica bearing fluids of volcanic origins. Geochemical studies have documented cases of hydrothermal (hot water) deposition of copper iron zinc and silver along with the silica. 南苏门答腊山脉发现的保存良好的珊瑚礁，证明了中新世（23mya）的海平面比以前高出许多。Eve

珊瑚玉被誉为有灵魂的宝石，它经历了地水的浸润，天火的炼狱，在吸取天地精华，日月正气的基础上，凝固了远古的生命，汇聚了远古的生灵。是由特定的地质事件将远古的生命定格在特定的历史时空。不能简单的用矿物学理解，也不能完全套用宝石学的理论。它就是它，一种不可被复制的独一无二的珊瑚化石玉……

Fossil Corals have been found in several provinces across the western Indonesian Islands of Sumatra and Java. These materials are the buried remnants of ancients reefs thrust up onto the land mass by plate collisions. They lie situated in the mountainous regionsof the Bukit Barisan Range from central to southern Sumatra and the rugged mountains of western and eastern Java. In east Indonesia there are fossil corals found on remote mountainous parts of Halmahera Island.

在印度尼西亚的苏门答腊岛西部和爪哇岛的几个省份，发现了珊瑚玉。这些物质是古代礁石的埋藏残余物，它们通过漫长的板块碰撞作用，被推挤到陆地上。它们位于Barisan的山区，该区域从苏岛中部到南部，一直延伸到崎岖不平的西爪哇和东爪哇的山脉。在印尼东部，Halmahera岛的偏远山区，也发现了珊瑚化石。

The discovery of well preserved coral reefswell into the mountains of south Sumatra is testament to the fact that sealevels in the Miocene (23mya) were once much higher than today.

南苏门答腊山脉发现的保存良好的珊瑚礁，证明了中新世（23mya）的海平面比以前高出许多。

Even the finest details of the coral species which formed these ancient reefs have been preserved by replacement with agate and other minerals. A wide range of coral species can be found.

即使是形成这些古老珊瑚礁的珊瑚物种的最细微的细节 也被玛瑙和其他矿物质所置换替代，而得以保存下来。所以我们可以找到一系列各种各样的，广泛的珊瑚物种。

During preservation the original calcium carbonate of the coral skeletons reacted with silica bearing fluids of volcanic origins. Geochemical studies have documented cases of hydrothermal (hot water) deposition of copper iron zinc and silver along with the silica.

在漫长的保存反应期间，原始珊瑚骨骼里的碳酸钙成分，与含二氧化硅的火山岩流体产生化学置换反应。 地球化学研究文献里，已经记录了铜，铁，锌和银，与二氧化硅在热液中沉积的情况。

Sumatra is a classical locality for “low sulfidation” hydrothermal gold and silver deposits. These were mined commercially by early Dutch explorers (Lebong Tandai Donok and Tambang Sawa) and are still the target of exploration and exploitation today (Way Linggo Rawas and Martabe).

苏门答腊是“低硫化”水热金和银矿床的经典地区。早期的荷兰探险家（Lebong Tandai，Donok和Tambang Sawa）在这里进行过商业开采，并且仍然是今天探索和开发的目标（Way Linggo，Rawas和Martabe）。

Low temperature silica minerals like opal and chalcedony (Agate) are the most common components of the fossilized coral. Some fine and micro-crystal aggregates (druse) or quartz have filled pockets in the leached portions of the stone. Some druses filled the channels which housed the soft parts of the coraline critters and were later cemented with clear agate causing the polished surfaces to glitter.

冷却后的二氧化硅矿物例如蛋白石（欧珀）和玉髓（玛瑙）是珊瑚玉最常见的成分。还有一些微晶聚集体（石英），填充在部分原石的内部，表面或者缝隙。 有些晶洞充满了如猕猴桃般软骨部分的通道，之后又和清澈透明的玛瑙胶合，这样就导致珊瑚玉抛光后闪闪发亮。

Locally there are pyrite crystals and other minerals disseminated in the agate which enhances the attractiveness and defines the structure of the original coral species.

当地的黄铁矿晶体和其他矿物也与珊瑚玉发生了部分侵染作用，这增添了珊瑚玉的魅力，并且界定了原始珊瑚物种的结构。

I have noticed the agatized fossil corals to vary from province to province. Some areas have more dissolved minerals and a greater range of colors than others.

我注意到珊瑚玉的品质根据省份的不同，而有所不同。 一些矿区的溶解性矿物质含量更多，颜色就比其他矿区丰富。

Some digging fields produce beautiful agatized coral heads in situ directly from weathered and oxidized rock formations. In other areas rounded cobbles of agatized corals are found in both old buried river channels and active river gravels far from the bedrock source.

一些矿区，在风化和氧化的岩层尖端就直接产出美丽的玉化度极好的珊瑚玉。在其他地区，在古老的河道里，和远离基岩源的河砾石中，都发现了鹅软石大小的珊瑚玉。

All in all these hard agatized fossil materials make spectacular lapidary material. As with any ornamental stone material there are some common colors and patterns and some rare beautiful collector pieces. With thousands of coral species in the fossil record…the hunt for the finest pieces could be endless.

总而言之，这些令人难以置信的坚硬珊瑚化石是惊人的宝石级材料。 与任何装饰石材料一样，有一些常见的颜色和图案，以及一些相当罕见的美丽收藏级品种。在有记录的成千上万的珊瑚化石品种中...寻找最美的品种的过程，可能是永无止境的。
