Shindler Carat Estimator - The Shindler Scale for gemstones

Unique and extremely useful, the Shindler Loupe lets you estimate a stone's weight, even if it is still mounted. It is an especially valuable tool for jewelers needing to estimate a stone that is still mounted in a piece of jeweler i.e. bracelet or ring. Naturally, it is also ideal for estimating loose stones.

Easy to use, it features a center scale that doubles as a 6.5mm gauge to evaluate a stone's weight and size up to 1ct. Simply place the stone face down on the inside of the replaceable 2.5cm clear tape protected screen.

Delivery of the Shindler Loupe includes a vinyl plastic booklet with instructions and calibration charts.

Inventing the Shindler Loupe, Bernard Shindler developed an ingenious solution to a problem in the jewelers trade that had never been satisfactorily solved. Shindler created the unique and very popular "Shindler Scale" which embodies specially graduated scales in a magnifier and thus enables the likely weights to be read off quite straightforwardly, even while the stones are still mounted.

Bernard Shindler enjoyed a long career in the diamond trade, which he much loved and in which he had many years of experience in inspecting and valuing precious stones (mostly in preparation for mounting in jewelers items). Combined with many years experience in precision engineering, his insight changed the way jewelers work and estimate precious stones.
