Intrinsix

Intrinsix answers one question before you bid on jewellery at auction: what is the most I should rationally pay? Paste a Catawiki lot link and Intrinsix pre-fills the specs (Pro uses AI extraction; you always confirm every value). Or enter any lot by hand, including loose diamonds and gemstones with no metal at all. THE ENGINE • Metal priced at the live spot (gold, silver, platinum) × purity × net weight • Stones at your wholesale €/ct, with an estimator to get you close • Every real cost layered in: buyer fee, VAT on fees, import VAT and duty for non-EU sellers, shipping • A margin of safety you control WHAT YOU GET • The maximum rational bid — one headline number • A five-tier value ladder from intrinsic melt to new-retail fantasy • Red flags to review before you commit • BID / PASS verdict against the current bid • A watchlist to track lots you're stalking WHAT INTRINSIX IS NOT It is not an appraisal and it never invents prices. Every number traces to your inputs or the live spot. The seller's "retail estimate" is the inflated top of the ladder, Intrinsix exists so you never bid against it. Intrinsix Pro (monthly subscription) adds AI lot extraction after one free analysis.
