Frequently Asked Questions

Is Los Angeles a good place to sell diamonds?
Yes, Los Angeles has a thriving secondary diamond market, especially in areas like the Jewelry District. The city's diversity and demand for luxury items make it a strong location for selling both certified and estate diamonds. Competition among buyers also means you can often secure a better price, provided you compare offers and work with reputable professionals.
What is the process of selling a diamond in Los Angeles?
Selling a diamond in LA typically involves an in-person or online appraisal. The buyer will examine the stone’s 4 Cs, check any certifications, and possibly test it with gemological tools. After the evaluation, a purchase offer is made. If you accept, the buyer may pay you immediately via cash or bank transfer. Some buyers also offer consignment options, where your diamond is listed for sale and you’re paid upon resale.
Are uncertified diamonds harder to sell in Los Angeles?
Uncertified diamonds are still sellable, but they may fetch lower offers compared to GIA or AGS certified ones. Buyers in LA will typically rely on their own expertise to evaluate uncertified stones, but the lack of official documentation introduces some uncertainty. If your diamond is uncertified but of good quality, consider having it graded before selling to potentially increase its value.
Can I sell designer or branded diamond jewelry in Los Angeles?
Absolutely. Branded diamond jewelry from designers like Tiffany & Co., Cartier, or Harry Winston can command higher resale values. In such cases, the item's craftsmanship, provenance, and brand recognition are taken into account alongside the diamond’s inherent value. Buyers who specialize in luxury resale are usually the best option for branded items.
What taxes or fees apply when selling diamonds in LA?
Generally, individuals selling personal property like diamonds in California are not required to pay sales tax. However, buyers may deduct a small fee for testing or refining, which should be clearly disclosed. It's important to request a detailed breakdown of how the offer was calculated so you can identify any hidden charges.
