Valuation Methodology
Estimate Midpoint
The house estimate range reflects the specialist's pre-sale assessment. The midpoint is the baseline fair-value anchor.
Buyer's Premium
Bling Gelt charges a 20% buyer's premium on the hammer price. All calculator outputs are hammer prices — add 20% for total cost.
Bid Velocity Signal
Lots with high bid velocity in the final 10 minutes historically close 18–35% above estimate. Factor this into ceiling bids.
Category Premium Rates
Jewelry lots average 108% of estimate. Fine art averages 97%. Use category context when anchoring your bid.
Live Comparables
Valuations are estimates based on current auction activity and historical premium data. They do not constitute financial advice. Past performance does not guarantee future results. All figures are hammer prices before buyer's premium.
