Frequently Asked Questions

Everything you need to know about our appraisal, security, and payment methods.

How long does the online valuation take?

Our gemology team typically completes an initial evaluation within 24 to 48 business hours after receiving your submission. If further research or documentation is needed, we will reach out promptly via your preferred contact method.

Is there any obligation to sell once I receive an offer?

No. All valuations and initial offers provided by Diasparx are completely complimentary and carry zero obligation. You have full freedom to consider our proposal or decline at any stage.

What is the difference between Direct Sale and Consignment?

Direct Sale provides immediate payment upon physical inspection and authentication of your piece. Consignment allows your jewelry to be marketed through our luxury client network and showroom, yielding a higher payout once sold.

How are items safely transported for physical inspection?

If you proceed after our preliminary valuation, Diasparx provides fully prepaid, tamper-evident, insured courier delivery directly to our secure vault facility. You can also schedule an appointment at our showroom.
