Description

A stunning, fine and impressive antique 1.80 carat emerald, 0.66 carat diamond, 18 carat yellow gold and palladium set trilogy ring; part of our diverse emerald engagement rings collection.

This stunning, fine and impressive antique trilogy ring has been crafted in yellow gold with a palladium setting.

The pierced decorated setting displays a stunning feature claw set 1.80ct octagonal cut emerald.

The emerald is flanked on either side by an impressive transitional modern brilliant round cut diamond, totalling 0.66ct.

The elevated and pierced decorated ring shoulders of this emerald engagement ring integrate with the main setting and blend seamlessly with the plain ring shank.

The interior of the ring shank is hallmarked with the 18 carat gold mark (18CT) a partial palladium mark (P) and has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as palladium and 18 carat gold.

This impressive antique emerald trilogy engagement ring is supplied with two IDGL diamond grading report certificates, in addition to an emerald report and certificate supplied by the Gemmological Certification Services (GCS)*.

Such antique examples in this very high quality and set with a stunning emerald are becoming increasingly difficult to locate.

This emerald trilogy engagement ring in yellow gold bears a three stone design steeped in symbolism, representing the past, present, and future of a relationship - making it a perfect choice for an engagement, in addition to an anniversary or vow renewal. The classic design and high quality also serve as a beautiful self-purchase, marking personal growth, milestones or the start of a new chapter with timeless elegance.

NOTE: * This documentation verifies that the gemstone shows minor amount of oil in fissures.

'Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.'

A trilogy ring, also known as a three-stone ring, traditionally symbolises the past, present and future of a relationship, gaining significant popularity during the Georgian and Victorian eras before evolving through the 20th century.

Period rings are typically crafted from precious metals such as yellow gold, platinum or white gold, featuring natural mined gemstones such as emeralds, rubies, sapphires and diamonds secured in claw or bezel settings.

Authentic pieces from the 1930s often feature hallmarks indicating metal purity, hand-cut gemstones characteristic of the period, and construction techniques typical of early twentieth-century goldsmithing.

Antique gemstone rings can be worn as a striking standalone statement piece or paired with modern stacking bands to create a contrasting, layered aesthetic.

Emeralds require gentle care due to their natural inclusions; they should be cleaned using warm soapy water without harsh chemical ultrasonic cleaners, and stored separately to prevent scratching from harder gemstones like diamonds.
