Terms of Use

The calculators and tools on this site are provided as-is for informational and educational purposes. They are free to use and require no account. Downloading a generated file asks for an email address; the privacy page covers what is collected, who else handles it, and how to have it deleted.

All calculations are based on standard jewelry-making formulas and may not account for every real-world variable: alloy springback, tool tolerances, soldering losses, stone irregularities, and so on. Always verify your measurements before cutting, and treat the results as informed starting points rather than guarantees.

Cold Brew Jewelry is not liable for material waste, project outcomes, or any other losses resulting from use of these tools.
