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
对新钻石存款的探索是基本上理解导致其形成的过程的基础知识，并从该过程中检测更丰富的相关矿物质，如Pyrope Garnet，铬偶联和铬铁矿。这些指示剂矿物质在流沉积物中检测到，冰川耕种，或在恒星和eClogite Xenoliths中检测到，在检测含有金刚砂和Lamproite管道的检测方面已经证明了富有成果。
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，允许快速地球化学映射的最小制备的样品，例如剪切钻芯和散点座。在不需要抛光或导电涂层的情况下分析样品，产生纹理分辨的和完全定量的组成图，用于鉴定特定的指标矿物质。布鲁克的M4龙卷风PLUS为增强的光元素分析、enabling detection of elements as light as carbon. The rapid scanning speeds of the Bruker micro-XRF instruments reduce turn around times on critical information needed in exploration targeting and reduce the number of samples and improve sub-sampling decisions for more detailed characterization steps.
- 用于扫描电子显微镜的量化系统，允许在抛光颗粒安装和薄截面中进行纹理和组合物的表征。使用BrukerAMICSautomated mineral platform to rapidly identify and characterize indicator mineral suites. Integrating the use ofQUANTAX EDS和量化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
制作成绩：评估钻石质量和真实性
在所有钻石中开采，只有20％的人让成绩视为宝石品质。在“四个CS”的基础上评估 - 颜色，清晰度，克拉特和切割 - 德米尔德需要以目的而被评分，最终将其作为宝石的价值。钻石也不再被局限于自然界的领域，现在相对容易制造合成钻石或非碳模仿。因此，重要的是要正确描述和分类要在开放式市场销售的任何钻石，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合作开发的，提供了钻石的快速和低成本分类，并检测合成或仿石材。甚至对于非专家的光谱师来说，甚至易于使用。
- 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气中心，提供用于颜色分级的工具，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.
