This high-precision jewelry scale gives you a confident measurement of your jewelry. It's small but useful and reliable. Not only that, you can use it to measure jewelry, but also for other sufficient measurements of small objects, such as cooking ingredients or food. Because it's made of grade A materials, it's easy to maintain and clean. It's self-sustaining. It's straightforward to power it up with a triple-A battery (which will have to be bought separately). You can get it for 100g, 200g, 300g, 500g, or 1000g maximum capability. Battery installation and manual control are incredibly user-friendly.
