Your collection deserves the right room.
Gemsza is a specialist-reviewed auction house for watches, fine art, antiques, jewellery, and more — built for sellers who want a curated audience, not a race to the bottom on price.
Every listing runs through automated fraud, duplicate, and quality checks before it goes live — buyers trust what they see, which means better bids on your lots.
Buyers bid with confidence because they're protected — that confidence is exactly what drives stronger final hammer prices for sellers.
Payments are handled through Stripe and paid out directly to your bank account once a sale clears — no chasing buyers, no manual invoicing.
Keep 100% of your hammer price.
Gemsza currently charges no seller commission. Whatever your lot sells for is what lands in your account, minus standard Stripe payment processing — that's it.
This is a launch offer while we're building our specialist categories and buyer base. We'll always tell our sellers directly, in advance, before any commission is introduced.
