Buyers of NYC reviews eligible Tiffany & Co. jewelry for a possible outright purchase at its Manhattan Diamond District office. The team may consider silver jewelry, gold and platinum pieces, diamond-set jewelry, engagement rings, designer lines, vintage and estate items, and other signed Tiffany creations.
Each evaluation is based on the physical item and its specific configuration. Collection, metal, gemstones, size, condition, alterations, completeness, supporting documents and current secondary-market demand may all affect the review. The purchase evaluation is free and carries no obligation to accept an offer.
Every ring is reviewed in-person by certified gemologists using professional diamond grading microscopes, colorimeters, and high-precision electronic balances.
We assess the principal center stone, side diamonds, fine platinum/gold settings, and designer signatures together rather than treating the piece merely as scrap metal.
Evaluations are conducted in a secure, discrete Midtown office. We never inquire about emotional circumstances, divorce, or reasons for selling.
Receive a transparent, no-obligation purchase offer with immediate payment via same-day wire transfer, company check, or cash upon acceptance.
We evaluate all styles, designs, and formats across antique, vintage, and contemporary eras.
Evaluating fine jewelry requires examining interdependent value drivers rather than applying an arbitrary single number.
The evaluation begins by identifying the collection, designer line (Elsa Peretti, Paloma Picasso, Jean Schlumberger), and model configuration. Market demand varies significantly across silver classics, modern gold lines, and high-jewelry suites.
The team examines visible Tiffany & Co. signatures, copyright dates, fineness stamps (925, 750, PT950), maker hallmarks, and crown serial inscriptions under 10x magnification alongside physical construction details.
Center diamonds, accent melee, colored gemstones, and pearls are evaluated for cut, color, clarity, and carat weight. Precious metal fineness is tested on calibrated scales to determine exact alloy composition.
Ring size, bracelet inner circumference, chain length, clasp tension, hinge movement, and earring post straightness affect wearability and secondary market resale viability.
Scratches, dents, stretched links, missing stones, heavy polishing, custom engravings, resizing marks, and third-party repairs are factored transparently into the evaluation.
Original blue boxes, pouches, Tiffany Diamond Certificate folders, sales receipts, and boutique service records support completeness and product provenance.
Sterling silver pieces are evaluated for collection-specific collector demand versus bullion melt. High-karat gold and platinum jewelry receive premium signed asset valuation.
Final valuation reflects live secondary market demand for the exact reference, size, metal, condition, and complete set presentation at the time of sale.
How different Tiffany jewelry designs, completeness levels, and materials are categorized for purchase evaluation:
The Tiffany Setting, T True, Schlumberger, and Victoria creations evaluated for diamond 4Cs, metal purity, and complete set documentation.
Heart tag toggles, ball chains, and silver cuffs evaluated for hallmark sharpness, link condition, and commercial secondary liquidity.
Missing earring pairs, stretched links, damaged clasps, and loose stones evaluated for recoverable diamond value and precious metal melt.
Important evaluation considerations regarding authentication, documentation, and material differences:
Tiffany & Co. does not provide authentication services for secondary-market transactions. Buyers of NYC conducts independent, professional purchase evaluations based on physical examination, hallmark verification, and gemological testing.
Our evaluations are independent assessments for outright purchase and are not affiliated with Tiffany & Co.
Original receipts, retail price updates, and Tiffany Diamond Certificates help identify stated specifications, purchase era, and stone characteristics, but none guarantees authenticity or current market value without physical verification.
Bring all available certificates, sales receipts, and folders to your appraisal appointment.
Sterling silver, 18k gold, and platinum creations follow distinct market routes. High-carat solitaires and designer gold lines carry substantial jewelry equity, while silver is evaluated for collection demand.
Every piece is assessed transparently based on its individual metal fineness, stone quality, and collector demand.
Ensure maximum financial return, immediate settlement speed, and counterparty security when liquidating your signed Tiffany jewelry:
Direct in-person physical evaluation in Manhattan’s Diamond District, model-specific valuation factoring collection demand, complete set premium, and immediate same-day payment with zero fees.
Conducted in a secure Midtown Manhattan appraisal suite. Non-destructive gemological and metal verification with complete transaction confidentiality.
Convenient if you intend to purchase new retail jewelry from the same establishment and accept store credit.
Trade-in values are typically restricted to store credit rather than cash liquidity, and new inventory prices may be marked up to offset allowances.
Effective for rare, historically important museum-grade Tiffany jewelry or Jean Schlumberger creations with established collector interest.
High seller commissions (15%–25%), cataloging and insurance fees, long catalog delays, and risk of unsold reserve buy-back fees.
Potential to reach an end buyer directly if selling a standardized commercial Tiffany silver model with complete packaging.
High exposure to fraudulent payment chargebacks, counterfeit dispute scams, shipping theft risks, and in-person meeting safety concerns.
Our evaluation protocol is conducted in-person at our Manhattan Diamond District office with complete transparency and zero obligation to sell.
Identify the jewelry type, collection when known, material, size, condition, documents and quantity. Photographs assist with preliminary routing but do not produce a final authenticity or price conclusion.
Bring the item, tools, matched pieces, loose components and available records to our Diamond District office. Appointments are preferred; walk-ins are welcome during published hours.
The team considers collection, configuration, marks, materials, stones, size, mechanism, condition, alteration, completeness and current secondary market route.
If Buyers of NYC is interested, the team describes the principal value factors and presents a firm, transparent purchase offer on the spot.
Accept and receive immediate same-day payment via wire transfer, certified check, or cash, or decline without obligation and retain your jewelry.
Bring the item as found. Polishing and repair before evaluation can change surface detail, marks, edges, dimensions, finish and evidence of prior work.
Do not aggressively polish sterling silver, remove oxidation, buff gold or platinum, resize a ring, remove an engraving, replace stones, repair a clasp or alter a chain solely to prepare for an evaluation.
Keep every loose or removed component, including earring backs, detached links, broken clasps, replacement parts, stones, chain sections and matched pieces together.
Bring boxes, pouches, receipts, diamond documents, repair records and prior appraisals when available.
Preserve original hallmarks, maker stamps, and intentional dark oxidation on silver designs without using harsh liquid chemical dips.
Single earrings, broken chains, and incomplete sets can still be considered through complete-piece, component, gemstone, or material routes.
Call 646-400-4553 before bringing a large collection, multiple high-value items, or a piece that may require special handling.
Key questions from our evaluation framework to ensure full transparency and an accurate offer comparison:
Ask whether the buyer reviewed the complete signed piece before considering metal or gemstone components.
Ask which collection, size, material, condition and completeness factors affected the offer.
Clarify whether there is an evaluation fee, seller fee, commission or later deduction.
Confirm whether the transaction is an outright purchase, consignment, auction submission or loan.
Ask when ownership transfers, which payment methods are available and when payment is completed.
Compare offers made for the same item in the same condition and with the same documents and components.
Every signed Tiffany & Co. creation brought to Buyers of NYC is evaluated on-site by certified gemologists, signed jewelry appraisers, and precious metal specialists.

No. Current secondary-market demand for the exact collection, material, size, condition and completeness determines value, not past retail prices.
No. Do not polish, dip or refinish it solely for the evaluation. Bring the item as found so the team can review original surface condition, marks and patina.
