Moissanite vs Diamond Price Calculator
Compare moissanite and diamond pricing side-by-side using carat weight, shape, quality grade, certification/brand effects, and full all-in totals including fees and tax.
Moissanite vs Diamond Cost Comparison
Enter both options and get total price, effective price per carat, and savings. Use the same carat to compare “like-for-like” scenarios or enter your real stone weights.
For the cleanest comparison, use the same carat for both and keep fees equal. If you are comparing equal millimeter size, carat weights may differ due to different densities.
This budget split mode estimates carat amounts for each stone type using your assumed unit pricing and multipliers. It is a planning tool, not a quote.
| Comparison angle | What it means | How to use this calculator |
|---|---|---|
| Same carat | Equal weight comparison | Use “Use Same Carat” for fast cost difference checks |
| Same mm size | Equal face-up appearance can differ in weight | Turn off same carat and enter your real carats for each stone |
| All-in total | Includes fees, markup/discount, and tax | Add setting or service costs to see the true checkout total |
| Effective price/ct | Lets you compare unit economics | Use this for sourcing and evaluating offers |
| Brand premium | Some moissanite brands cost more | Use moissanite brand multiplier to model premium sellers |
| Diamond type | Natural vs lab-grown often has different pricing | Select diamond type and adjust base $/ct to match your market |
The most important input is the base price per carat for each option. Use real prices from your market (retail or wholesale) for meaningful comparisons.
