Frequently Asked Questions...
whats the best inexpensive way to test gold? An electronic device (£50) or the little acid test bottles (£20)?
The electronic tester seems neater but I am always skeptical about accuracy of cheap electronic gadgets.
and how is it possible to distinguish between 9,14,18 carat and pure gold with acid test?
Answer:
I am not selling this stuff. You can read about scratch testing and electronic tester here:

The cheapest method of all is the density test. you need an accurate scale and a way to accurately measure a quantity of water, like a graduated cylinder. Pure gold has a density of 19.32 grams / cubic centimeter.
Analysis of alloys with the density method is complicated. Send me an e-mail and I will send you a draft of a paper I'm working on.
