The GEMS 10X Hastings Triplet Diamond Estimator Scale Loupe with Handheld LED/UV Light is a professional-grade combination tool designed for gemologists, appraisers, and jewelers who need accurate diamond evaluation in one compact kit. At the heart of the system is an 18 mm diameter 10X Hastings Triplet loupe with a built-in diamond weight estimating scale — paired with a handheld light source that delivers both LED and ultraviolet illumination for comprehensive stone analysis.
Unlike competing estimator loupes that use 15X magnification — which can be more difficult to handle in practice — this tool uses the industry-standard 10X magnification recognized for diamond grading by professional gemological organizations. The built-in diamond size and weight estimating scale makes it especially valuable during appraisals and valuations, allowing you to quickly reference stone dimensions and estimated carat weight without switching instruments.
The handheld LED/UV light unit attaches directly to the loupe, forming a unified diamond viewing tool. The UV illumination lets you check for fluorescence on the spot, adding another layer of gemological analysis without reaching for a separate lamp. When not in use, both units store together in the included metal case.
Optics are manufactured in Japan and assembled in Taiwan.
