A satisfactory diamond inspection and laser engraving inspection loupe for consumers. Higher power when you need it, lower power when you are doing regular inclusion examination. These were carefully chosen by Garry Holloway to meet his exacting standards of performance. There are many look a likes for sale, but without any recognized endorsement. Garry and I offer these as 8x and 20x rather than as marked at 10x. We want you to know the 10x marking is a bit incorrect.
