What We Buy from Gramercy Park Sellers

Engagement Rings Round, princess, cushion, oval, emerald, pear, marquise — all cuts, all settings. Solitaires, halos, three-stone, vintage. GIA/AGS certified stones command the highest premiums. We assess center stone and setting separately.

Loose Diamonds Certified and uncertified. All shapes, all sizes. GIA, AGS, IGI, EGL certificates assessed. We grade uncertified stones in-house using professional equipment. Fancy colored diamonds — yellow, pink, blue — evaluated at full collector value.

Inherited Collections Estate lots, inherited jewelry collections, downsizing situations. We handle complete collections with care — cataloging, grading, and pricing every piece individually. No pressure to sell everything.

How We Grade Your Diamond — The 4 Cs

C Cut Excellent & Ideal cut diamonds return the most light — and command the highest prices. We grade cut from Poor to Excellent using proportional analysis.

C Color Graded D (colorless) to Z (light yellow). D–F colorless stones are most valuable. We grade color using master comparison stones under controlled lighting.

C Clarity FL (Flawless) to I3 (Included). We assess inclusions under 10x magnification. Eye-clean VS2 and SI1 stones are most liquid in the current market.

C Carat Weight determines size and dramatically affects value. Stones at magic weights (1.00ct, 1.50ct, 2.00ct) command premiums. We weigh loose stones precisely.

“A 1-carat G VS2 round brilliant that a local Gramercy jeweler offers $3,500 for might be worth $5,500–$7,000 in today’s diamond market. We check current Rapaport pricing and pay what your diamond is actually worth.”

Common Questions

Gramercy Park Diamond Sellers Ask…

How far are you from Gramercy Park?+

Take the 4, 5, or 6 train northbound from 23rd Street to 51st Street. Walk west to 47th Street — 30 W. 47th Street, Suite 8006. About 20 minutes from Gramercy Park.

How do you determine the value of my diamond?+

We grade your diamond using the 4 Cs — cut, color, clarity, and carat weight — using professional GIA-standard equipment. We then cross-reference current Rapaport diamond price lists and recent comparable sales. We show you exactly what data we’re using and explain every factor before making any offer.

Do I need a GIA certificate to sell my diamond?+

No. We buy certified and uncertified diamonds. A GIA certificate does add value — it confirms the grade independently and increases buyer confidence, typically adding 10–20% to the offer. But we grade uncertified stones in-house using professional equipment and make fair offers on both.

Do you buy engagement rings with the diamond still in the setting?+

Yes. We evaluate the center diamond and the setting separately. The diamond is assessed on the 4 Cs. The setting is assessed for metal content (platinum, 18k, 14k) and any side stones. You receive a combined offer for the complete piece, or we can break it down by component if you prefer.

What is Rapaport pricing and why does it matter?+

The Rapaport Price List is the global benchmark for diamond pricing, updated weekly by Rapaport Group. All serious diamond dealers, including us, use it as the baseline. Your offer is calculated as a percentage of Rapaport based on your diamond’s specific grades. We show you the Rapaport price we’re using before making any offer.

Do you buy colored diamonds?+

Yes. Natural fancy colored diamonds — yellow, pink, blue, green, orange, red — are among the rarest and most valuable gems. We assess natural vs. treated color, intensity grade (Faint through Vivid), and secondary hues. For significant colored diamonds, we may request additional time to source collector buyers for maximum value.

How quickly do I get paid?+

Same day. Accept the offer and receive cash or same-day wire immediately. Most evaluations complete in 15–20 minutes. Walk in from Gramercy Park, walk out with cash.

Do you pay more than a pawn shop or local jeweler?+

Consistently yes — and significantly so. Pawn shops and local jewelers use wide margins because they buy retail and sell retail. We specialize exclusively in precious metals and gemstones, operate in the Diamond District where competition is intense, and price against current wholesale market data. A diamond a local NEIGHBORHOOD shop offers $3,500 for might be worth $5,500–$7,000 here.
