Technological advancements in jewellery manufacturing and gemstone identification are opening new possibilities for jewellery design and origin determination.

Busch & Co GmbH & Co KG, which provides professional-grade gem and jewellery processing tools such as round burs, twist drills, bearing cutters and circular saws, to name a few, recently unveiled its latest T-Speed series.

It comprises five tools with cylindrical or conical working parts, offering quick and efficient cutting. A new carbide cutter is an ideal tool for shaping and cutting the insides of rings as well as machining and trimming sprues and lugs on cast pieces, according to the company.

One notable feature of these tools is the smooth rounded tip or safety bevel at the transition from the smooth tip area to the side surface of the cuts, which helps prevent abrasive contacts and groove formation. The titanium nitride coating further optimises tool life.

In addition, Busch & Co introduced a steel version of its signature carbide cutter – PavéCut 447AU. This steel version not only streamlines the pre-drilling and shaping process into a single step, but also provides a gentle milling experience. It is particularly effective for processing softer precious metals like silver and yellow gold in a precise and time-saving manner.

Meanwhile, Gübelin Gem Lab has raised gemstone authentication to a new level through its Gemtelligence system, which ensure consistency and precision in the analysis of coloured gemstones. It determines the origin of emeralds, rubies and sapphires by employing artificial intelligence and deep learning for the first time.

Building on this powerful breakthrough, Gübelin Gem Lab has extended its expertise to a broader market through its new Gem Passports service. The company’s Hong Kong and New York branches have been offering this service since June 2024, with plans to introduce it onsite at its Bangkok facility in September 2024, revealed Gübelin Gem Lab.
