Move the pointer across the plate for a magnified crop, as you would run a loupe over the surface in the viewing room. Using a keyboard, step between the named details instead.

Anti-sniping
A bid placed inside the final 3 minutes of this lot extends its close by a further 3 minutes, from the moment of the bid, and does so again for every bid inside the window. Only this lot is extended; the rest of the sale runs on. The rule exists so that a lot is won by the highest bidder rather than by whoever has the fastest connection in the last two seconds. The countdown above shows the extension as it happens.
Or bid another way
- Absentee. Leave a written maximum with the clerk. The house bids on your behalf up to it, and no higher, taking the lot as cheaply as the competition allows.
- Telephone. A member of staff calls you before the lot and bids to your instruction. Arranged at least 24 hours in advance.
- In the room. Register at the desk and take a paddle number.
Demonstration site. Hammer & Co is a fictional auction house; every lot, estimate, bid, result and provenance chain on this site is invented for the purpose of showing the design. No bid placed here is a real bid and nothing here is offered for sale.
Catalogue note
Fifty-four graduated round brilliant-cut diamonds in a claw setting, estimated in the aggregate as H to J colour and VS to SI clarity. The stones are estimated in the mount and have not been removed for grading; the department says so rather than quoting a certified figure it does not hold.
Condition report
Very good Reported by Nadia Behrens on August 28, 2026
All stones present. Three with minor chips at the girdle, visible under 10× magnification and disclosed here. The clasp is secure with a figure-of-eight safety. Light surface scratching to the platinum consistent with wear.
A condition report is an opinion, honestly held, given as a courtesy and not a warranty. It is not a substitute for examining the lot yourself, and the absence of a reference to a defect does not imply that the lot is free from it. Every lot is sold as is.
Provenance
- to date Private collection, Chicago.
Every provenance chain on this demonstration site is invented. No real collection, sale or ownership history is described.
