钻石世界：从想象力到现实
介绍
Diamonds
Favored for millennia as cut stones due to their unsurpassed vibrance, gem-grade diamonds form the centerpiece to many jewelry pieces. However, because diamonds are the hardest natural occurring mineral on our planet and their naturally high thermal conductivity, those that don't make the grade as cut stones end up in a myriad of industrial uses. Bruker's advance analytical solutions support all aspects of the diamond industry from exploration, to extraction, and to grading.
多尺度分析
多尺度分析: Exploration for New Diamond Occurrences
对新钻石沉积物的探索是基于对导致其形成过程的过程的基本理解的建立，并且从发现更丰富的相关矿物质（例如Pyrope Garnet，Chromium Diopside和Chromite）。这些指标矿物质在溪流沉积物，冰川耕种或橄榄岩和叶绿石异种石中检测到，在检测含钻石的金伯利岩和兰普林管方面已被证明是富有成果的。
Bruker provides analytical solutions for rapid characterization of granulated materials (tills, sediments, crushed rocks) and drill core for positive identification of diamond indicator minerals. Solutions include:
- M4龙卷风Micro-XRF仪器，它允许快速对最小准备的样品（例如切钻和散射安装）进行快速地球化学映射。分析样品无需抛光或导电涂层，产生纹理分析和完全定量的组成图，以鉴定特定指标矿物质物种。布鲁克的M4龙卷风PLUS量身定制以增强光元素分析，从而能够检测到像碳一样轻的元素。Bruker Micro-XRF仪器的快速扫描速度减少了探索目标所需的关键信息并减少样品数量并改善子采样决策的时间，以实现更详细的表征步骤。
- 用于扫描电子显微镜的Quontax系统可以在抛光谷物安装和薄部分中以千分尺尺度表征纹理和成分。使用布鲁克的AMICSautomated mineral platform to rapidly identify and characterize indicator mineral suites. Integrating the use ofQUANTAX EDS和Quantax WDSdetectors allows the quantification of the full suite of major, minor and trace elements needed to best evaluate diamond prospectivity and fertility in regional exploration.
Assessing Diamond Quality and Authenticity
提高成绩：评估钻石质量和真实性
在所有开采的钻石中，只有20％的钻石将其视为宝石质量。根据“四个CS”进行评估 - 颜色，清晰度，克拉和剪切 - 迪蒙德斯需要为目的进行分级，并最终将其作为宝石的价值。钻石也不再局限于自然世界的境界，现在制作合成钻石或非碳模仿相对容易。因此，重要的是要正确描述和分类在公开市场上出售的任何钻石，以确保客户具有可追溯性，而钻石是真正的文章。
Bruker provides a full range of solutions that suit every application and analytical need in the diamond analytical workflow. Diamond quality and grading tools include:
- ALPHA II Diamond Analyzer，与HRD-ANTWERP合作开发，提供了钻石的快速和低成本分类，并检测合成或模仿石。即使是针对非专家的谱系师，也设计为易于使用。
- EMX series电子顺磁共振（EPR）分析仪提供了一种明确的技术，用于量化钻石中的氮中心，提供颜色分级的工具，并区分合成和天然钻石。
- TheSKYSCAN 1275 X-ray microscopeprovides an exact model of the raw diamond including the 3D location of mineral inclusions, which affect the clarity grade of a diamond and hence its price. This enables the cutter to optimize cut, clarity and carat weight.
