Service and scope
These conditions apply to DPC Rapaport Price’s website and Diamond Price Checker app together with the Terms of Use and Privacy Policy. The service provides reference calculations and available price-list information; it does not buy, sell or guarantee the value of a diamond.
Reference prices and rounding
Round calculations use the Round table; the other supported shapes use the Pear table as an indicative benchmark, not an independent shape-specific appraisal. Adjustment is applied as base price × (1 + RAP / 100). Total also multiplies by carat weight. The mobile API rounds each returned amount independently to a whole USD using half-up rounding. Market, cut, fluorescence, grading and transaction terms can affect actual value.
Free website allowance
Each website account receives two successful calculations. Invalid or unavailable calculations do not consume the allowance. After the allowance is used, continue through the app link. Saved-result deletion, logout and repeat login do not replenish the allowance. There is no website subscription checkout.
Apple subscriptions and cancellation
App subscription price, term and any offer are displayed by Apple before confirmation and may vary by region. Apple handles purchase and renewal billing. Manage and cancel subscriptions in your Apple Account settings before the next renewal under the applicable purchase terms. Deleting this service’s account or app does not cancel a subscription.
Refund requests
For an Apple-billed purchase, request a refund through Apple at reportaproblem.apple.com. Eligibility and approval depend on Apple’s rules and applicable consumer law; we do not promise a refund or a fixed refund period. Cancellation and refund requests are separate actions.
Support and account removal
Use our Contact Us form for questions about the calculator, saved results, account or privacy. We do not request full card details or your password. Official third-party subscriptions are administered by their own provider. Account deletion removes associated active backend data as described in the Privacy Policy.
Fair use and mandatory rights
Do not automate abusive requests, defeat access restrictions, misrepresent estimates as certified appraisals or redistribute content without the necessary rights. We may restrict misuse and temporarily interrupt service for maintenance. These conditions do not override mandatory consumer protections or rights that cannot legally be waived.
