Classic Diamond Solitaire
These classic diamond solitaire pieces offer enduring elegance through a single, striking stone.
What these pieces are
A classic diamond solitaire centres on a single stone, presented primarily as rings and engagement rings alongside occasional pendants. These pieces span eras from the Art Deco period of the nineteen-thirties through to nineteen-fifties and nineteen-sixties vintage designs, as well as later than nineteen-sixty creations.
The most common form you will meet on this page is the ring, featuring either a prominent old cut stone or a natural diamond secured on a precious metal band. Designs range from nineteen-thirties art deco configurations to mid-century classic contemporary settings.
Makers and designers shape these items in various precious metals, providing a focused selection of classic jewellery that highlights the central gem without distraction.
How they were made
Goldsmiths construct these jewels using platinum, eighteen-carat white gold, eighteen-carat gold, and fourteen-carat yellow gold. These durable metals form robust bands and pendant mounts designed to support and display the single diamond securely.
Each piece incorporates a natural diamond, including specific examples utilising old cut stones or graded grades such as H-I colour with Si1 clarity. The setting techniques focus attention entirely upon the central gem's optical properties.

What varies in quality
The standard of a classic diamond solitaire rests upon the inherent qualities of the central stone and the weight of the metal used in the band. Pieces featuring larger carat weights, such as one point zero four carats or one point fifteen carats, distinguish themselves within the range.
Workmanship varies through the precision of the metal setting and the character of the diamond cut, moving from mid-century productions to earlier nineteen-thirties art deco examples with old cut stones.
