0.40ct Diamond Ring
A 0.40ct diamond ring encompasses several distinct historical forms, most frequently appearing as solitaire rings, full eternity bands, or cluster configurations surrounded by coloured gemstones.
The selections span from Edwardian and Art Deco designs through Mid-Century and 1970s pieces, reflecting shifting stylistic preferences over several decades.
Solitaire and cluster variations dominate the available examples, often pairing the central diamond with platinum or various carats of gold.
How they were made
Craftsmen utilised precious metals including platinum, 18ct white gold, 18ct yellow gold, and 14ct gold to form the structural mounts and settings.
Stones were secured using traditional techniques such as claw settings, pavé settings, and flush channels for eternity bands.
Many examples incorporate old cut diamonds alongside calibrated rubies, emeralds, sapphires, tanzanites, and aquamarines.
