Jewelry Weight Calculator
Use our free Jewelry Weight Calculator to convert weights between gold, silver, platinum, copper, wax, resin, and other jewelry casting materials.
This tool helps jewelry designers, CAD modelers, manufacturers, and casting professionals estimate equivalent metal weights while maintaining the same model volume. Whether you need to convert a wax model to 18K gold, estimate the weight of a platinum ring, or compare different precious metals, this calculator provides fast and accurate results based on material density.
Popular applications include:
• Wax to Gold conversion
• Jewelry CAD weight estimation
• Ring and pendant weight calculations
• Jewelry casting preparation
• Precious metal cost planning
Simply select the source material, enter the weight in grams, choose the target material, and the calculator will instantly display the equivalent weight.
What Is a Jewelry Weight Calculator?
A Jewelry Weight Calculator is a tool used to estimate how much a jewelry design will weigh when produced in different materials. Since every metal has a different density, the weight of the same ring, pendant, bracelet, or earring can vary significantly depending on the material selected.
For example, a ring that weighs 10 grams in Sterling Silver 925 will weigh approximately 15.1 grams if produced in 18K Yellow Gold, assuming the design volume remains unchanged.
This type of calculation is widely used by jewelry manufacturers, CAD designers, and casting houses during product development and production planning.
How Jewelry Weight Conversion Works
Jewelry weight conversion is based on density.
Materials with higher density weigh more than materials with lower density when the volume is identical.
Common examples include:
- Wax → Gold
- Wax → Platinum
- Sterling Silver → 18K Gold
- Copper → Platinum
- Resin → Precious Metals
Our calculator automatically converts the weight using material density values commonly used in jewelry manufacturing.
Common Jewelry Material Densities
| Material | Density |
|---|---|
| Wax | 0.93 |
| Resin | 1.30 |
| Copper | 8.40 |
| Fine Silver | 10.20 |
| Sterling Silver 925 | 10.00 |
| 14K White Gold | 12.60 |
| 14K Yellow Gold | 13.00 |
| 18K White Gold | 14.60 |
| 18K Yellow Gold | 15.10 |
| 18K Rose Gold | 15.30 |
| 22K Gold | 17.70 |
| 24K Gold | 19.10 |
| Platinum 900 | 18.60 |
| Platinum 950 | 20.20 |
Wax to Gold Calculator Guide
One of the most common applications in jewelry manufacturing is converting wax model weights into precious metal weights.
A wax model used for casting is significantly lighter than gold or platinum. By using density-based calculations, jewelers can estimate the expected finished metal weight before casting.
This information is valuable when:
- Quoting custom jewelry projects
- Estimating precious metal costs
- Planning production
- Determining retail pricing
Jewelry CAD Weight Estimation
Jewelry CAD designers often need to estimate metal weight before manufacturing.
If you work with software such as Rhino, MatrixGold, 3Design, ZBrush, Blender, or Nomad Sculpt, weight estimation is an essential step during product development.
By converting between different materials, designers can evaluate production costs, optimize designs, and provide more accurate quotations to clients.
