Frequently Asked Questions

How can I sell diamonds through JS Diamonds Inc.?
Selling diamonds involves a straightforward evaluation process. You can visit the store directly or schedule an appointment for personalized assistance. The diamonds are examined based on cut, clarity, color, and carat weight using professional gemological equipment. After the assessment, a competitive offer is made reflecting current market rates. The entire process is transparent, ensuring sellers receive fair value for their diamonds.
Can I sell both certified and non-certified diamonds?
Yes, both certified and non-certified diamonds are accepted for purchase. Certified diamonds come with grading reports that assist in faster evaluation, but even without certificates, each diamond is carefully examined by gemologists. Non-certified stones are tested for authenticity and quality on-site, ensuring a fair offer is provided regardless of documentation.
Is an appointment mandatory to meet diamond buyers?
While appointments are not mandatory, booking one can help avoid waiting times and ensures a dedicated evaluation session. Walk-ins are always welcome, but scheduling an appointment guarantees a smooth and expedited selling experience with immediate attention from an expert.
How is the final price for my diamond calculated?
The final price is determined after assessing the diamond's 4Cs—cut, clarity, color, and carat weight. Market demand and current diamond prices also influence the offer. A detailed explanation of the valuation is provided, ensuring full transparency in how the price is arrived at.
Do diamond buyers purchase mounted diamonds in rings or other jewelry?
Yes, diamonds set in jewelry like rings, necklaces, or bracelets are accepted. The diamonds are evaluated separately from the setting, while the metal (gold, platinum, etc.) is also assessed for its resale value. Sellers receive a combined offer that accounts for both diamond and metal content.
