Sell Diamonds for Cash — Top Dollar for Diamond Jewelry & Rings
Get a free, professional evaluation of your diamonds and diamond jewelry. We pay top dollar based on the 4Cs. No obligation to sell.
Selling diamonds requires expertise and trust. Astoria Gold Buyer Pawn Shop pays top dollar for diamond rings, diamond jewelry, and loose diamonds. Our experts evaluate diamonds using the 4Cs grading system — cut, color, clarity, and carat weight — to ensure you get the best possible price.
Diamond value depends on the 4Cs: cut quality, color grade (D-Z), clarity (inclusions and blemishes), and carat weight. We also consider factors like fluorescence, polish, and symmetry. Having a GIA certificate can increase confidence and value.
How Diamonds Are Evaluated
Diamond evaluation uses the standardized 4Cs system developed by the Gemological Institute of America (GIA). Cut refers to how well the diamond's facets interact with light. Color is graded from D (colorless) to Z (light yellow).
Clarity measures internal inclusions and surface blemishes. Carat weight measures the diamond's size. We use professional tools to assess each factor and make transparent offers based on the diamond's true market value.
- Cut — how well the diamond reflects light (Excellent to Poor)
- Color — graded D (colorless) to Z (light yellow)
- Clarity — measures inclusions and blemishes (FL to I3)
- Carat weight — diamond size (1 carat = 200mg)
- GIA certificate increases confidence and value
