Diamond Buyer NYC
Sell Diamonds for Cash in NYC
Diamond rings, earrings, pendants, and loose stones — free evaluation based on the 4Cs.
Astoria Gold Buyer Pawn Shop purchases diamonds and diamond jewelry from customers throughout Queens and New York City. Whether you have an engagement ring, a pair of diamond earrings, a pendant, or a loose diamond, we provide free evaluations based on the internationally recognized 4Cs grading system.
Diamond valuation is specialized work. Our team examines each stone for cut, color, clarity, and carat weight — the four factors that determine a diamond's quality and market value. We explain our assessment clearly so you understand the basis for our offer.
How Diamonds Are Evaluated: The 4Cs
Every diamond is graded using four key characteristics established by the Gemological Institute of America (GIA):
Cut refers to how well the diamond's facets interact with light. A well-cut diamond reflects light beautifully, making it more valuable. Cut grades range from Excellent to Poor.
Color is graded on a scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are the most valuable, though fancy colored diamonds (like pink or blue) can be worth significantly more.
Clarity measures the presence of internal inclusions and surface blemishes. Grades range from Flawless (FL) to Included (I3). Most diamonds have some inclusions — the fewer and less visible, the more valuable.
Carat weight measures the diamond's size. One carat equals 200 milligrams. Larger diamonds are rarer and command higher per-carat prices, especially above 1 carat, 2 carats, and 3 carats.
Diamond Jewelry We Purchase
We buy diamonds in all types of settings and conditions:
- Engagement rings and bridal sets
- Diamond wedding bands
- Diamond earrings (studs, hoops, drops)
- Diamond pendants and necklaces
- Tennis bracelets
- Diamond rings (all styles)
- Loose diamonds (certified and uncertified)
- Certified diamonds (GIA, AGS, EGL)
- Fancy colored diamonds
- Diamond watches
Do You Need a Certificate?
A diamond grading certificate from a recognized laboratory like GIA or AGS provides detailed information about your diamond's quality. Having a certificate can streamline the evaluation process and sometimes increase confidence in the offer.
However, a certificate is not required. We can evaluate and make offers on uncertified diamonds. If your diamond is certified, bring the certificate — it saves time and provides useful reference data.
If you're not sure whether your diamond is certified, check for a laser inscription on the girdle (the thin edge of the diamond) or look for a certificate number on any paperwork you have.
Factors That Affect Diamond Value
Beyond the 4Cs, several other factors influence what your diamond is worth:
Certification from a reputable lab like GIA adds confidence and can increase value. The setting also matters — a diamond in a designer platinum setting may be worth more than the same stone in a basic gold band.
Market demand for certain shapes fluctuates. Round brilliant cuts typically hold their value well, while fancy shapes like oval, pear, and emerald have grown in popularity. Current fashion trends can affect resale value.
The condition of the diamond and setting is important. Chips, scratches, or damaged prongs can reduce value. If you have the original box and documentation, these can help.
