Diamond Buyers New York FAQs

What should I look for in a reliable diamond buyer in New York?
Reputable buyers in New York will have industry credentials, transparent pricing, excellent customer reviews, and a brick-and-mortar location. Many are located in the Diamond District, known for competitive pricing and expert appraisals. Look for those who offer a clear explanation of how they determine value.
Can I sell diamonds without certification in New York?
Yes, although certified diamonds usually fetch higher prices due to verified quality. Non-certified diamonds are still accepted and will be appraised using gemological tools to estimate their 4 Cs. In such cases, getting a GIA certificate prior to sale may increase your final offer.
Are fancy cut diamonds harder to sell in New York?
Not necessarily. While round brilliant diamonds are in highest demand, New York buyers also deal in fancy cuts like cushion, emerald, and pear. However, resale demand varies, so price offers may differ depending on current trends. An experienced buyer will know the current market appeal of your diamond shape.
Do New York diamond buyers accept small or melee diamonds?
Yes, but smaller diamonds (under 0.25 carats) usually carry lower resale value unless they’re part of a designer piece. Buyers will often bundle multiple small diamonds into a single lot for resale. Larger diamonds with good clarity and color grades tend to command stronger prices.
How fast is the selling process in New York?
The process is typically quick—most evaluations take 15 to 30 minutes, and payment is made the same day. Buyers in New York are known for their efficiency, especially in high-traffic areas like Midtown Manhattan and the Diamond District.
