My own readings, in pounds. The first point is the first reading I took; after that a point goes on only when a reading comes in 5% or more away from the one before it, which is why the gaps are uneven.

A 20x, if you already have a 10xJewellers' loupes, the same chrome loupe is stamped 10X, 20X and 30XThe black hexagon again, printed TRIPLET 20X 20.5mm-LENS, with a zipped case, a cleaning cloth and a lanyard in a box. Twenty times means holding it closer to the stone and seeing a smaller circle, so it is a second loupe for looking harder at something a 10x has already found, not a first one. Nineteen jewellers' loupes from one search and the order export, and underneath them a handful of designs. One folding chrome loupe with a 21mm lens is sold under seven listings, and six of them show it stamped 10X, 20X and 30X on the same body. Diamonds are graded at 10x, a stronger lens has to be held closer and shows a smaller circle, and triplet, stamped on most of them, is the word worth looking for. Published 4 Oct 2026
