Having a carat scale handy whether you’re engaged in selling, buying or making jewelry helps you achieve a strong reputation in your business. It’s not easy to gain the trust of your target consumers so you need a good quality carat or jewelry scale as your constant tool. Now what distinguishes the top rated products in the best carat scale reviews from others on the market?
A reliable digital interface
The best carat scales are electronic or digital. They run on batteries and show you the weight displayed on their easy-to-read (preferably) LED backlit digital readout. They also allow you to connect directly to an electric socket using a supplied AC adapter. Digital carat scales are generally equipped with plenty of additional capabilities. Some models are able to store data and others have a parts counting function. Those elements are quite useful when you have to keep track of how many items you have weighed in a set of jewelry for instance, or when you’re counting the stones detached in a setting. It is also useful for data tracking. The digital readout should show a decimal value, which should be accurate to the thousandths of a measuring unit.
Models with enhanced digital features are able to switch between various units of measurement to accommodate the needs of both you and your customers. A premium carat scale should come with options from grams, ounces, diamond weight total (dwt) or pennyweight, troy ounces (ozt) for measuring gold, and grain (gn).
Suitable capacity and sensitivity for your purpose
Consider what you will be weighing so you can determine what capacity you want in your carat scale. A specially sensitive carat scale should be able to weigh up to the largest gemstones while easily handling lightweight ones. A tare function enables a premium carat scale for gemstones to consider the weight of the jewelry setting or the gemstone scoop and will only display the weight of the gemstones. A memory feature keeps track of the items already measured so you don’t get lost in your procedures.
Remember that not all digital carat scales are made equal. Some are quite small and make it difficult to read the display. Give the unit a spin to find out if you’re comfortable with its use. Otherwise, you can always go for a model with a large enough digital display. Make sure the display will still be readable even with the draft shield up or covering the weighing pan. A good carat scale for diamonds and other gemstones should offer a 0.001 gram readability, while lapidary scales or those used by artisans who form mineral, stones or gemstones into decorative items such as faceted designs, cameos, engraved gems and cabochons, should offer a readability of 0.01 gram. For weighing precious coins and metals, you will want a readability of 0.1 gram.
Easy to use
Whether you’re using the device as a carat scale for gold or for any other jewelry application, you want a generously-sized platform where you can have room to weigh a variety of items. Stainless steel platforms are best for their resistance to corrosion and durability to ensure years of use. The supplied scoop serves to hold very tiny stones for weighing. It should be a separate component for easy placement and removal of items.
If you intend to carry the carat scale on business trips, it should come supplied with an AC adapter and a hardy case that protects the scale and all other items in the package. Some premium models ship with diamond tweezers to simplify stone weighing, such as when you need to add or remove a piece from a set. A calibration weight ensures consistent measuring.
