Frequently Asked Questions

How can I sell my diamonds at JS Diamonds Inc.?
Selling diamonds is a seamless process where you can visit the showroom or initiate the selling process online. Once the diamond is presented, gemologists perform a detailed evaluation considering cut, clarity, color, and carat weight. After the assessment, a market-aligned offer is provided. The process is transparent and ensures sellers get fair market value with immediate payment after acceptance.
Do I need a certificate to sell diamonds?
While having a diamond certificate can speed up the evaluation process, it is not a requirement. Diamonds without certificates are still thoroughly examined using professional gem-testing equipment. The absence of a certificate does not hinder the ability to receive a fair and accurate price for the diamond.
Can I sell damaged or chipped diamonds?
Yes, damaged or chipped diamonds are accepted for purchase. The valuation focuses on the remaining intact quality of the stone, including its weight and clarity. Though imperfections may slightly affect the price, sellers can still receive a competitive offer for diamonds that are no longer in perfect condition.
What types of diamond jewelry can I sell?
All forms of diamond jewelry such as rings, earrings, bracelets, necklaces, and loose stones are eligible for sale. Whether the pieces are modern designs or heirloom items, each diamond is individually assessed to determine its true value in line with current market rates.
How is payment made after selling my diamonds?
Once the evaluation is complete and the offer is accepted, payment is processed immediately. Sellers can opt for cash payment for smaller transactions or secure bank transfers for larger amounts, ensuring a hassle-free and quick settlement.
