GoldScope AI
Read full descriptionHide full description
GoldScope AI screens gold rings and coins using on-device photo measurement, controlled 15 cm acoustic capture, and physics-backed comparison workflows. Use it to: - weigh the item and run a quick water test for an exact density, shown against 14K to 24K gold and the metals fakes are made from - estimate ring and coin dimensions from photos beside an ID card, license card, or calibration marker - record clean drop or tap audio, with each drop counted live, and view spectrum evidence - see one clear result with how strong each piece of evidence was and what would firm it up - export readable spectrum graph reports GoldScope AI is a screening and comparison tool. It is not a certified assay, appraisal, laboratory test, or guarantee of value or purity.

Know what to weigh before you melt. Smelter brings jewelry calculations, material references and practical learning together in one workshop app for iPhone and iPad. Prepare a gold alloy, adjust purity, plan a casting or make use of precious-metal scrap. Get clear results for the job in front of you, whether you work at the bench, teach jewelry making or are learning your craft. ALLOYS, PURITY AND SCRAP Calculate alloy proportions, raise or lower fineness, and find the fine-metal content of a batch. Work with gold, silver, platinum and palladium, combine scrap, and save useful alloy recipes. CASTING AND BENCH TOOLS Estimate metal weight from a wax model, convert between weight and volume using density, and calculate ring-blank dimensions and stock weights. Ring-sizing tools, investment mix calculations and unit converters keep everyday workshop calculations together. MATERIALS LAB AND ACADEMY Compare materials and their properties, consult reference densities, and create custom profiles using supplier data or your own measurements. Explore structured lessons and interactive exercises on alloys, purity, casting and workshop practice.
