We hold a very large supply of high grade precision jewels. The majority are deep ruby-red whilst some of the larger sizes are clear. They are suitable for watch, clock, chronometer, scientific instrument, and medical instrument use.

Jewels are sold in assortments of 10 or 20 sizes (5 jewels per size), or in quantities of 10’s, 100’s, or 1,000’s, or even 10,000’s for individual sizes. The table below gives details of the most popular sizes available. We do though stock further sizes, too numerous to mention, including some jewels in settings, so please contact us with your requirements for a quote.
