Brutalist Pyramid Ring
An exceptional brutalist pyramid ring in the minimal mid century modernist style. Dating from the 1960s, the head is a truncated square pyramid, the lower half formed from a single piece of black onyx, and the top from white gold set with nine icy-white diamonds. The architectural form perfectly complements the minimalist design aesthetic, and hallmarks to the outer band indicate that it was made in the Catalan city of Barcelona, Spain. Crafted in 18ct white gold.

US Shipments
Parcels going to the United States are currently subject to the Trump administration's 10% "reciprocal tariff". Until August 29th (2025), parcels under $800 remain tariff-free under the de minimis exemption.
We declare our parcels under HTS code 9706 (antique over 100 years old) which reduces import duties to zero. This means the 10% "reciprocal tariff" is all you should be charged by customs*. At this time, you are responsible for any taxes levied at the border.
US customs will require a SS# or business tax ID to clear parcels valued over $2500. UPS will request this information from you directly. More information about this can be found on the US Customs and Border Protection website.
* The tariff situation is being handled extremely erratically by the Trump administration, as such it's susceptible to change as short notice. We will keep the information on this page updated as best we can.

Condition
We offer detailed and accurate condition reports on each listing. These pieces are antique, vintage, or pre-loved and often over 100 years old so they're going to have lived a life. A healthy patina and the odd scuff or scrape is quite normal... it's part of their charm! Everything we present has been checked over by our jeweller and should be good for wear for many years to come (unless otherwise stated) but please remember to treat them with appropriate care and consideration for their age.
