Jewellery Balances – Precision Scales for Precious Metals & Gemstones
Our jewellery balances are high-resolution weighing instruments designed for the accurate measurement of precious metals, gemstones, diamonds, and fine jewellery. With readability from 0.001 g and compact, elegant designs suited to workshop and retail counter environments, they deliver the precision and reliability that jewellers, goldsmiths, precious metal dealers, and pawnbrokers require for valuation, quality control, and trade applications.
Weighing precious materials demands a higher standard of accuracy than most general-purpose scales can provide. A difference of 0.01 g in a gold or diamond transaction can have significant financial implications — making the choice of balance critical. Our jewellery balances use high-resolution load cells with fast stabilisation, ensuring quick, accurate readings even for the smallest stones or metal quantities. Many models include troy ounce (ozt), pennyweight (dwt), carat (ct), and grain weighing units as standard, alongside grams — covering the full range of units used in the jewellery and precious metals trade.

Frequently Asked Questions
What weighing units do jewellery balances support?
Most jewellery balances support grams (g), troy ounces (ozt), pennyweight (dwt), carats (ct), and grains as standard. Some models also support tael and momme units for Asian precious metal markets. Always confirm the available weighing units for the specific model before purchasing if non-standard units are required.
What readability do I need for weighing diamonds and gemstones?
For diamond and gemstone weighing, a readability of 0.001 g (1 mg) or finer is recommended, as one metric carat equals exactly 0.2 g. A balance reading to 0.001 g can therefore resolve to 0.005 ct — sufficient for most gemstone grading and valuation purposes. For very small stones below 0.1 ct, a microbalance with 0.0001 g readability may be more appropriate.
Do jewellery balances need to be trade approved?
For commercial transactions where weight determines the price paid or charged — such as buying or selling gold, silver, or gemstones — a trade-approved (OIML Class II or III) balance is required by UK weights and measures legislation. We stock trade-approved jewellery balances suitable for legal-for-trade precious metal and gemstone transactions. Contact us to confirm approval status for specific models.
How do I get accurate readings when weighing small items?
For best accuracy: allow the balance to warm up for 15–30 minutes before use, perform a calibration check with a certified weight, use the tare function to zero out any container or dish, and ensure the balance is on a stable, level, vibration-free surface away from air currents. A draft shield is recommended for readabilities of 0.01 g or finer.
Can I get a calibration certificate with my jewellery balance?
Yes. Traceable calibration certificates are available on request for all models in our range. For trade-approved balances used in commercial transactions, periodic recalibration is recommended to maintain compliance with weights and measures requirements — contact our team for service and calibration support.
