1.20ct Diamond Ring
A 1.20ct diamond ring brings together substantial gemstone weight and historical design across decades of fine jewellery production.
1.20ct Diamond Ring
A 1.20ct diamond ring encompasses a variety of historical designs, from early Victorian examples to mid-century modernist creations. Buyers exploring this category encounter cluster arrangements, solitaire settings, and multi-stone bands that place the diamond at the visual centre of the piece.
The versions most frequently met on this page span the Edwardian period, the Art Deco era, and the mid-century decades. These pieces utilise precious metals such as platinum and 18ct gold to support the principal stones alongside sapphires, rubies, and opals.
Materials and construction methods
Master jewellers combined durable platinum with yellow and white 18ct gold to form the structural mounts for these rings. Platinum provided the tensile strength required for delicate claw settings and intricate pierced galleries, particularly during the Edwardian and Art Deco periods.
Stones were cut by hand using historical techniques, yielding old European cuts, old transitional cuts, and rose cuts that interact differently with light compared to modern machine-cut equivalents. Gemstones including sapphires, emeralds, and rubies were then calibrated and set securely within cluster, navette, or solitaire configurations.

Distinguishing quality in historical rings
Quality separates pieces by the precision of the stone setting and the integrity of the metalwork. Superior examples display symmetrical claw work, crisp millegrain edges, and securely flush-set secondary stones that remain flush with the surrounding metal surface.
The calibre of the central diamond and accompanying coloured gemstones dictates the upper tier of the range. Fine specimens feature stones with balanced proportions, harmonious colour distribution, and hand-cut facets that maximise brilliance without compromising the structural harmony of the mount.

The 1.20ct Diamond Ring Glossary
- Cluster ring
- A ring style featuring a central gemstone surrounded by a border of smaller stones. This arrangement maximises visual impact and was favoured during the Edwardian and Art Deco periods.
- Old cut
- A diamond facet style cut by hand before modern machine standardisation. These stones typically feature smaller tables, higher crowns, and open culets that produce a softer, warmer candlelit sparkle.
- Navette ring
- A ring featuring a pointed, boat-shaped silhouette designed to elongate the finger. The shape accommodates a central diamond flanked by smaller gems within an extended mounting.
- Millegrain
- A decorative technique involving a row of tiny raised metal beads along the edge of a setting. This detail softens harsh metal lines and was widely utilised in Edwardian jewellery.
- Solitaire
- A ring featuring a single prominent gemstone mounted on a plain or shoulder-set band. The design directs focus entirely onto the qualities of the primary stone.
1.20ct Diamond Ring: Frequently Asked Questions
How do I care for a vintage diamond ring?
Vintage diamond rings require gentle maintenance to preserve delicate settings and softer accent stones like opals or emeralds. Clean them periodically using warm water, mild soap, and a soft brush, avoiding harsh chemical ultrasonic cleaners.
Store each piece individually in a lined box to prevent metal scratches and gemstone abrasion. Regular inspection by a professional jeweller ensures claws remain secure and settings tight.
What periods do these rings come from?
The pieces originate from various historical eras spanning the late nineteenth century through to the mid-twentieth century. Common periods include the Victorian era, the Edwardian period, and Art Deco designs from the nineteen-thirties and nineteen-forties.
Later examples extend into mid-century modernist styles and nineteen-seventies creations. Each period brings distinct metal choices and geometric or floral motifs to the mount.
Can I wear a 1.20ct diamond ring daily?
Diamonds and platinum offer exceptional durability suited for regular daily wear. However, rings featuring softer accent stones or high-set cluster configurations benefit from careful handling during physical activities.
Removing the ring before heavy lifting, gardening, or swimming protects the historical metalwork and prevents accidental impact damage to the prongs.
How are Edwardian and Art Deco rings different?
Edwardian rings typically showcase light platinum mountings with intricate lacework, floral motifs, and millegrain detailing. They often utilise old cut diamonds paired with natural sapphires or pearls in graceful, organic arrangements.
Art Deco rings transition into bold, symmetrical geometry with sharp lines and strong colour contrasts. They frequently incorporate calibre-cut sapphires, onyx, and stylized stepped shoulders surrounding the central diamond.
