SMALL TOOLS. BETTER DECISIONS.
Find a UK ring size reference, estimate precious-metal content and explore necklace lengths with four interactive tools.
Turn an inside diameter into a useful sizing reference.
Open tool02Estimate metal content from weight, purity and your rate.
Open tool03Calculate gold content using your chosen price per gram.
Open tool04Explore lengths and see where they typically sit.
Open toolUse the ring size finder to compare inside diameter or circumference with a published sizing chart. Use the necklace length visualizer to explore common positions and convert centimetres to inches. Confirm the final fit against yourself and the retailer’s guidance.
The gold price and jewellery value calculators multiply the metal weight by your chosen pure-metal rate and purity fraction. They do not use a live price feed. Retail premiums, stones, making charges, taxes and a buyer’s margin are outside that calculation.
The outputs help explain sizing and metal content. They do not replace a professional fit check or jewellery appraisal. Every tool includes instructions, a worked example and relevant questions.

Each calculator has a copy-result button, and you can change inputs to compare examples.
The ring size finder matches an inside diameter or circumference to an approximate chart reference. The necklace length visualizer compares centimetres and inches and illustrates common positions. The gold price calculator estimates gold content from weight, purity and a rate you provide. The jewellery value calculator applies the same method to supported gold, silver and platinum purities.
Use millimetres for ring measurements, centimetres for necklace length and grams for metal weight. Metal calculations accept grams or troy ounces and a pure-metal rate per gram in your selected currency, not a rate already adjusted for the selected purity. Necklace lengths can be entered in centimetres or inches. No live price feed is connected. Exclude stones and other non-metal parts from the weight you are estimating.
A reference size needs confirmation against the actual retailer's chart and design. A visual length marker does not reproduce your body proportions. A metal estimate excludes stones, workmanship, retail costs and a buyer's deductions. Change one input at a time to understand its effect, copy the result if useful and read the worked example on the dedicated tool page.
