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…
