Three bottle tester, tests for all carats of gold and also silver.
Each acid changes colour when applied to the metal, and the colour (and the speed of the reaction) will tell you if it is gold, and the carat. Also tests for silver.
This is the 'industry-standard' tester, clearest instructions, colour-reactions easy to see, even for the colour blind.
Each set includes a needle-file (to check for plating), a sample of copper (to see the reaction on 'base' metal), a magnet (gold and silver aren't magnetic), and a very clear instructions booklet - they all fit neatly into the box with the acids.

Supplied in strong wooden box which contains the accessories and instructions (there is also a summary of the instructions fixed to lid). The instructions are very simple, there are even instructions for the colour blind, you don't have to distinguish between green, grey and brown.
This is THE 'industry standard' tester. The simplest (easy to use) set on the market. Strong wooden box for safety, accessories included, childproof bottles. We have been manufacturing this model since 1986.
Accessories: magnet, needle file, sample of 'base' metal (copper).
The first bottle tells you if the metal is not gold or 9ct or better than 9ct.
The second bottle tells you if the metal is 14ct, 18ct, 22ct or 24ct (and it's accurate enough to gauge 'in between' these readings)
The third bottle tests for silver (Sterling, 925 grade or 'continental' .800).
Each bottle contains enough fluid for 100 to 150 tests and has a shelf life of between one and two years (the 'use by' date is printed on each label). Each bottle is semi-transparent so that you can see how much fluid remains.

The fluids are acid - you will need a steady hand and good eyesight; the bottles must be kept well away from children and stored upright in a cool place - if this is not possible DO NOT buy one of these.
