Change in the building’s median $/sf over each window, adjusted to a constant-quality (average-floor) unit so it reflects price — not which floors happened to sell. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.

The Gemstone trades on the strength of two features that rarely appear together on West End Avenue: prewar Bing & Bing architecture and condominium ownership. Pricing is best read on a price-per-square-foot basis, with the condominium structure itself functioning as a premium input against the cooperative inventory that dominates the corridor. Within the building, value is driven by exposure, floor height, room proportion, and renovation condition. Apartment-level closing detail should be sourced from public records for full transactional context, and pricing should be validated against the most recent comparable sales at the time of offer.

The complete recorded-sale history for The Gemstone, compiled from NYC Department of Finance transfer records and verified listing data, then enriched apartment-by-apartment by The Roebling Team research desk. Across sales with a public asking price, the building carries a median listing discount of 2.3% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy here.

Price per square foot over time

125 sales with a known square footage, by closing date.

Each dot is one recorded sale with a known interior square footage, plotted by closing date against price per square foot. The line is the median $/sf each year, adjusted to a constant-quality (average-floor) unit — so it reflects price movement, not which floors happened to sell that year. Individual sale prices in the table below are unadjusted — and you can click any dot to jump straight to that sale.

Every recorded sale

Sort any column; filter by unit or keyword. Prices are the recorded transfer amount at the NYC Department of Finance. Every sale sits in one of three states: counted in the building’s medians and trend; shown but excluded as a non-arms-length or nominal transfer; or shown and ⚑ flagged for review — a possible duplicate filing or an extreme $/sf outlier, held out of the statistics pending manual verification rather than allowed to move them.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01182-7501) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans. Storage, parking, and commercial units are excluded from all figures. Floor- and line-level $/sf are time-controlled (each sale measured against the building’s going rate at the time of sale) and expressed at today’s pricing, so they isolate the floor or line premium rather than blend two decades of market movement.

Selling here

Price to the building’s real trajectory, not a guess — we’ll position your line against its true comps to maximize the outcome.
