Quantity:
Measure the stone across the top (across the table) and from top to bottom (from table to cullet). Then use the formulae we provide in the instruction sheet to calculate the weight. We include the formulae for diamonds and 16 other gemstones, all you will need is a calculator or if you don't actually have a calculator we will find you one for £2.00.Works easily with loose stones. Also works with stones mounted in jewellery providing you have access to the bottom of the stone to take one of the measurements. More...

You might think to yourself: rather than measure a stone, look up charts and formulae, then use a calculator to work out the weight (see previous item)- can't this all be done automatically, with a computer built into the gauge??The answer is yes (at a price).Select the stone (see MORE for list of stones), measure it, the weight will be displayed.
