Did you spot this incredible necklace strung with benitoite beads in the latest Journal of Gemmology (Volume 38, No. 6)? 💡 A Gem Note explores the origin of the rough benitoite material used to fashion this necklace and how each piece was hand-shaped and polished to create 640 beads in total. According to the author, the yield after drilling was just over 3.5%, resulting in four necklaces measuring 16 inches long. 📸 Necklace with beads ranging from 3 to 6 mm in diameter, which were cut and polished from translucent material that was obtained decades ago from the Benitoite Gem mine in California, USA.

What is a Foliated Metamorphic Rock? Before diving into the specifics, it’s crucial to understand what foliated metamorphic rocks are. Foliated rocks are characterized by their layered or banded appearance, often resulting from the alignment of mineral grains during the rock’s formation. This texture provides valuable insights into the geological conditions and history of a particular region. Foliated metamorphic rocks, in particular, are formed from the alteration of pre-existing rocks under the influence of heat and pressure. Now, let’s explore the world of foliated metamorphic rocks in more detail. https://lnkd.in/dv7GcyZt

"Is This Stone Traceable?" With a growing need for sustainability in all spheres of life, consumers are interested in the roots and source of gemstones. Establishing a transparent history of a gemstone's journey is the aim of traceability, which ensures moral behaviour and transparency. Gemstones sourced from reputable mines or suppliers often come with certification from organisations like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI). These certificates detail the gemstone's characteristics and sometimes its origin, aiding in traceability. The traceability of a gemstone depends on various factors, primarily its origin and the processes it undergoes from extraction to market. Furthermore, technological developments have brought forward techniques to improve traceability. Some gemstones feature laser inscriptions or microchips with information about their origin and journey. Despite obstacles, efforts to increase traceability in the gemstone industry, combined with consumer education, are leading to positive improvements by promoting ethical behaviour and sustainable sourcing. #gemstonetraceability #gemstonesourcing #jewellerydesign  #gemstonejewellery #gemstones
