Emerald Cut Diamond
When you handle an emerald cut diamond, you touch a piece born in eras spanning from Edwardian grace to mid-century modernism.
Emerald Cut Diamond
An emerald cut diamond forms the centrepiece of rings, earrings, pendants, and brooches across periods from the late nineteenth century to the mid-twentieth century. The selection ranges from Edwardian cluster rings to Art Deco platinum mounts and retro cocktail rings.
Buyers meet variations involving platinum, yellow gold, white gold, and rose gold alongside coloured stones such as emeralds, aquamarines, and sapphires. Platinum mounts from the Art Deco period appear frequently among these listings alongside later gold settings.
How they were made
Craftsmen utilised platinum predominantly during the Art Deco and Edwardian decades to create strong, delicate settings that held diamonds and emeralds securely. Yellow and white gold appeared in various purities including fourteen carat and eighteen carat formats, particularly in mid-century designs.
Goldsmiths combined step-cut stones with old cut diamonds, brilliant cuts, and cluster arrangements to maximise light play. Techniques involved millegrain edges, intricate gallery work, and robust prong settings suited to daily wear.

What varies in quality
The standard of an emerald cut diamond piece depends upon the clarity and origin of any accompanying emeralds, such as Colombian stones with minor oil treatments. Metalwork preservation also dictates value, with crisp platinum channel work and intact millegrain indicating superior craftsmanship.
Proportion and symmetry in the mounting separate standard commercial items from exceptional creations. Original settings that retain their structural integrity without replacement prongs or altered shanks hold greater appeal for collectors.
