A push pull clasp does not make you solve a puzzle. One straight motion along the clasp opens or closes it, which is why it works so well for jewelry that comes off often.
Visually Speaking
Garlands, bows, swags, foliate scrolls, open latticework: those are the Edwardian signatures. The vocabulary came from eighteenth-century French decorative arts and got rendered in platinum with a lightness the originals never had. The result was jeweled lace, and it still reads that way today.
Origin Story
The principal sources of gem-quality natural diamonds are Russia's Yakutia region, Botswana, Canada's Northwest Territories and Nunavut, Australia, South Africa, Angola, and Namibia. Each area produces diamonds with distinctive trace element profiles that gemologists can sometimes use as provenance indicators.
