Free to start. Worth paying for.

Yes. Vaults are private by default. Showcase pages are public only when you explicitly publish them. We don't sell data, run ads, or share your vault.

You drop a photo of a piece, and Luster drafts the record for you — maker, weight, fineness, year, form, and any pour mark or signing — tuned for hand-pour and bullion imagery. You confirm or edit what matters before saving. Faster than typing, sharper every time.

Yes, soft monthly limits sized to match each tier — about 250 pieces a month on Collector and about 999 a month on Studio. You can see your current usage in Settings. If you hit a limit, you can keep cataloging manually, or upgrade.

When you use photo cataloging or research, the photo and description go to our model providers, processed per-request and not used to train their models. Corrections you make sharpen identification for everyone who uses Luster — never the photos themselves, never your private fields. The vault itself never leaves our database. Full details on the Privacy page.

Subscriptions (Collector and Studio), plus a small eBay affiliate commission when you buy through links. We don't sell your data. Ever.

Export everything to CSV or JSON in one click — same export on every plan, including Free. LSTR codes stay stable so any external records you've kept still resolve.

No. They're documentation prose for your records and your insurer. For high-value pieces, work with a credentialed appraiser (ISA, ASA).

Hand-poured bars, rounds, coins, prototypes, custom pieces, error coins, fractionals, gold, silver, and the oddballs in between. If it's metal and you collect it, it fits.
