这World of Diamonds: From Imagination to Reality

从工业磨料必威东盟体育到最精美的珠宝,钻石捕捉了我们的想象力。布鲁克(Bruker)帮助您发现这些珍贵矿物中被捕获的世界。

Introduction

钻石

由于其无与伦比的充满活力,宝石级的钻石构成了许多珠宝碎片的核心,因此被割成石头。但是,由于钻石是我们星球上最难发生的矿物质及其天然高热电导率,因此那些不会使坡度的矿物质随着切石而最终产生无数的工业用途。必威东盟体育Bruker的提前分析解决方案支持钻石行业的各个方面,从勘探,提取到分级。

Multi-scale Analysis

多尺度分析:新钻石发生的探索

天然钻石及其相关的指示矿物作为橄榄岩(顶部)的一部分和夹杂物的一部分

Exploration for new diamond deposits has been built upon a fundamental understanding of the processes leading to their formation, and from that the detection of the more abundant associated minerals such as pyrope garnet, chromium diopside, and chromite. These indicator minerals, detected in stream sediments, glacial tills, or in peridotite and eclogite xenoliths, have proven fruitful in detection of diamond-bearing kimberlite and lamproite pipes.

布鲁克(Bruker)提供了分析解决方案,以快速表征颗粒状材料(耕种,沉积物,压碎岩石)和钻芯,以阳性鉴定钻石指示矿物质。必威手机客户端解决方案包括:

  • M4 TORNADOmicro-XRF instrument, which allows rapid geochemical mapping of minimally prepared samples such as cut drill core and scatter mounts. Analyze samples without the need for polishing or conductive coating, producing texturally resolved and fully quantitative compositional maps for identification of specific indicator mineral species. Bruker'sM4 Tornado Plusis tailored for enhanced light element analysis, 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.
  • QUANTAX systems for Scanning Electron Microscope allow characterization of textures and compositions at the micrometer scale in polished grain mounts and thin sections. Use Bruker's友善自动化的矿物平台,以快速识别和表征指标矿物套件。整合使用Quantax编辑andQUANTAX WDS探测器允许量化最佳评估区域探索中钻石的前途和生育所需的主要,次要和微量元素的整个套件。

评估钻石质量和真实性

Making the Grade: Assessing Diamond Quality and Authenticity

Of all diamonds mined, only 20% make the grade to be considered gem quality. Evaluated on the basis of the "four Cs" – colour, clarity, carat and cut –diamonds need to be graded for purposes and ultimately for their value as gems. Diamonds are also no longer confined to the realms of the natural world, it is now relatively easy to make synthetic diamonds, or non-carbon imitations. Consequently, it is important to correctly describe and classify any diamond that is to be sold in the open market to ensure that the customer has traceability, and the diamond is the genuine article.

Bruker提供了全方位的解决方案,适合钻石分析工作流程中的每种应用和分析需求。钻石质量和分级工具包括:

  • Alpha II钻石分析仪,,,,developed in collaboration with HRD-Antwerp, provides rapid and low-cost classification of diamonds, and detection of synthetic or imitation stones. Designed to be easy to use, even for non-expert spectroscopists.
  • EMX系列Electronic Paramagnetic Resonance (EPR) analyzers provide an unambiguous technique for quantifying nitrogen centers in diamonds, providing a tool for color grading, and to distinguish between synthetic and natural diamonds.
  • Skyscan 1275 X射线显微镜提供了原钻石的精确模型,包括矿物质夹杂物的3D位置,这会影响钻石的清晰度,从而影响其价格。这使切刀能够优化切割,清晰度和克拉重量。
