Gem stones can you cost you, not only in price, but in profits and reputation if there is disagreement in weight. Jewelers must be extremely precise weighing diamonds and other precious stones since a difference of 1 points (99 points to 100 points) can change the value of a stone by over 30% in some situations. A one carat diamond is the same thing as a 100 point diamond. There are 5 carts to 1 grams. Accurate weighing is a must and this Mettler diamond scale meets the requirements for most precious stone dealers and distributors. Weighing diamonds is so important and in many states the law requires a NTEP Approved balance like the JS1603C/A. Whether you are simply weighing small loose diamonds or large polished gem stones for a collector or museum you need accurate carat weight.

Battery Powered or AC Adapter - Mettler JS Jewelry Balances operate on either standard AA batteries or AC Adapter. Now you'll can operate your jewelry weighing balance with or without power supply. This is a huge selling point since main people in the jewelry industry attend trade shows and power is not always available or you need to pay those huge fees to have an AC receptacle at your booth. Every model in the JS, JP and JL Series can operate from a battery or AC mains supply. Ten pre-programmed applications- Mettler JS electronic jewelry balances have 10 application modes to suit a variety of weighing needs. Note - in order to use any of these functions they must first be set on one of the user selectable function keys. These applications include piece counting, percent weighing, check weighing, statistics, totaling, multiplication factor weighing, division factor weighing, density determination, routine test, and diagnostics.

Finally, all of these features also make JS1603C/A digital gem stone balance easy to clean. Custom Weigh Units - JS digital diamond carat balances offer two ways of creating your own customized weigh units by using multiplication factor weighing which multiplies the sample weight value in grams by a predefined factor and calculates it to a predefined number of decimal places. Another weighing option is division factor weighing which divides the sample weight value in grams by a predefined factor and rounds it to a predefined number of decimal places.
