Diamond planner
Your assumptions.
A transparent comparison.
Bring two quotes into one view. Calculations compare entered costs only; they do not assess diamond quality, authenticity or market value.
The calculation, in plain view.
Total carats = stone quantity × carats per stone.
Diamond amount = total carats × quoted price per carat.
Subtotal = diamond amount + other costs.
Assumed tax = subtotal × tax rate ÷ 100.
Total = subtotal + assumed tax.
The model assumes uniform stones within a scenario and tax on the entire subtotal. Actual tax treatment, duties, currency conversion and import costs may differ. Include applicable additional costs explicitly and check treatment with your supplier.
Cost does not establish comparability.
Differences in origin category, grading, measurements, cut, fluorescence, treatments, report coverage and commercial terms can matter. The planner does not rank either diamond as better value.
