Frequently Asked Questions
Adam's jewellery scales feature industry-specific weighing units, allowing them to be used for a wide range of jewellery weighing tasks. For gemstones, such as diamonds, rubies or emeralds, the carat unit can be used, as well as the Troy ounce, which can also be used to weigh precious metals. Pennyweights are also used for weighing precious metals, and mommes and grains to weigh freshwater and cultured pearls. Our balances also have typical gram and ounce measurements for weighing jewelry such as earrings, necklaces and watches.
While you could weigh your jewellery on a regular kitchen scale to check the weight, it’s not recommended. Kitchen scales very rarely offer the same level of precision, being made for everyday weighing of ingredients rather than for the high accuracy weighing of jewellery. Kitchen scales will also lack any of the necessary jewellery weighing units such as carats, Troy ounces or mommes, making it impossible to weigh gemstones or precious metals without complicated conversions.
It’s also important to consider that professional jewellery scales must legally be trade approved for selling all gemstones, precious metals and jewellery. It’s legal to use non-trade approved scales to check the weight, but not for any transaction or for determining price.
For simply checking the weight of a piece of jewellery, a trade approved scale is not required. However, a certified scale is needed for any transactional process where an item is bought or sold, meaning trade-approved scales must be used in pawnbrokers and professional jewelers. As a seller, you are responsible for ensuring that the digital jewellery scales you are using are suitable for trade use within your locality.
Trade approved, professional jewellery scales ensure that items are weighed accurately, and therefore the customer is getting exactly what they are paying for; likewise, it means your business is not losing profit by undervaluing your goods.
