Dimensions summary
This listing offers one pricing dimension: Product Access (Units). It is a free subscription that grants access to the gemstone auctions data product. There are no tiers or usage add-ons to choose between. You subscribe once to unlock access, with no charge tied to how much you consume. The dimension covers auction and private-sale records for jewelry and gemstones, drawn from the vendor's proprietary dataset.
Top-of-mind questions for buyers
One unit is a single subscription that unlocks access to the gemstone auctions data product. It covers auction and private-sale records for jewelry and gems, drawn from the vendor's proprietary dataset. Access is tied to the subscribing account, not metered by how many records you view or query.
The data records realized results, not asking prices. Each figure is the hammer price plus buyer's premium, converted to US dollars at the transaction date. It reflects what jewels and gems actually sold for across auction houses, private sales, and dealer records, with no estimates or list prices included.
The dataset updates daily. New results flow in as auction houses close their sales. Your access stays current with these ongoing additions for the duration of your subscription, so you do not pay extra as new records are added.
