Diamond and Aquamarine Jewellery
Diamond and aquamarine jewellery brings together ice-blue beryl and sparkling stones in rings, pendants, and brooches spanning the Edwardian era to the mid-century.
Diamond and Aquamarine Jewellery
Diamond and aquamarine jewellery encompasses rings, necklaces, drop earrings, and brooches set with beryl and diamonds. The pieces found here range from Victorian and Edwardian examples to Art Deco, 1940s Retro, and 1950s mid-century designs.
Rings form a substantial portion of the selection, spanning simple cluster rings and elaborate cocktail rings to trilogy settings and twist designs. Large central aquamarines frequently anchor these rings, accompanied by smaller accent diamonds.
Pendants, necklaces, and drop earrings appear across multiple periods, often pairing emerald-cut or oval aquamarines with platinum or white gold chains and mounts. Brooches incorporate figural and floral motifs alongside geometric Edwardian and Art Deco arrangements.
Materials and Construction
Metals used across these items include platinum, 18ct white gold, 18ct yellow gold, 14ct yellow and rose gold, 11ct gold, 9ct gold, and 15ct gold, alongside palladium. Platinum dominates the Art Deco pieces, providing a strong, bright setting for geometric cluster work.
Stones are cut in various shapes, with emerald-cut and oval aquamarines paired with round, old-cut, or baguette diamonds. Additional gems such as rubies, demantoid garnets, pearls, tourmalines, and peridots appear in specific period items.

The object types range from delicate drop necklaces and cluster pendants to substantial cocktail rings exceeding thirty carats.
Assessing the Pieces
Quality rests in the balance between the scale of the central aquamarine and the precision of the surrounding diamond work. Stones with deep, clean blue colour and high transparency elevate an item above standard commercial grades.
Setting execution dictates durability and refinement, particularly in platinum and white gold mounts where claw or bezel work secures large beryl crystals. The harmony between the metal framing and the gemstone cut determines the overall presence of the jewellery.

The Diamond and Aquamarine Jewellery Glossary
- Aquamarine
- A pale blue to light green variety of beryl utilised as the primary gemstone in these items. Its name derives from the Latin for seawater.
- Cluster ring
- A ring featuring a central stone encircled by a border of smaller gems, usually diamonds. This setting style maximises the visual impact of the centre stone.
- Old-cut diamond
- A diamond cut by hand before modern machinery, characterised by a smaller table, higher crown, and open culet. These stones often appear in Edwardian and Victorian pieces.
- Baguette cut
- A step-cut diamond shaped into a narrow rectangle, frequently used as side stones in Art Deco and mid-century designs. The straight facets produce a clean, linear shine.
- Trilogy ring
- A ring set with three stones symbolising the past, present, and future. In this selection, they typically feature an aquamarine flanked by diamonds.
Diamond and Aquamarine Jewellery: Frequently Asked Questions
How do I care for my aquamarine jewellery?
Aquamarine is a durable beryl, but harsh chemicals and ultrasonic cleaners can damage surrounding soft stones or pearls. Clean gently with warm soapy water and a soft brush.
Store pieces individually in fabric-lined boxes to prevent harder diamonds from scratching the softer beryl surface or adjacent precious metals.
Are these pieces suitable for daily wear?
Rings and pendants set in platinum or 18ct gold withstand regular wear if constructed solidly. Large cocktail rings with high stone settings require more care against knocks.
Selecting a secure bezel or low-profile cluster setting helps protect vulnerable stones during everyday activities.
What is the difference between Edwardian and Art Deco settings?
Edwardian mounts rely on yellow gold and platinum-topped silver, favouring delicate garland, floral, and lace-like openwork. These designs feel light and organic.
Art Deco items utilise solid platinum or white gold, emphasising geometric symmetry, sharp angles, and structured baguette or emerald-cut stone arrangements.
How can I tell if a stone is natural aquamarine?
Natural aquamarine displays subtle dichroism, showing faint colour shifts when viewed from different angles, alongside possible natural inclusions under magnification. Synthetic stones or glass alternatives often lack these organic growth characteristics.
Consulting hallmarks and period-appropriate mounting techniques provides further context regarding the authenticity of the gemstone.
