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.

For looking into a stone, with its own lightJewellers' loupes, the same chrome loupe is stamped 10X, 20X and 30XAn aluminium tube loupe, 10x with a 20.5mm lens, that lights the stone from the side against a dark background, the darkfield arrangement used for looking at what is inside a gem rather than its surface. Battery powered, with a pouch and a box. A specialist's tool, and among the dearest here. 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
