Trilogy Engagement Ring in Yellow Gold

0.83 ct Diamond and 18 ct Yellow Gold Twist / Trilogy Ring - Vintage 1991

A fine and impressive 0.83 carat diamond (total) and 18 carat yellow gold trilogy engagement ring; part of our diverse vintage diamond jewellery and estate jewelry collections

SKU A5156


This fine and impressive diamond trilogy ring has been crated in 18 ct yellow gold.

The pierced decorated elliptical frame displays a central 0.33 ct modern brilliant round cut diamond flanked on either side by two slightly smaller modern brilliant round cut diamonds, all held in relief within individual basket style settings.

The twist design shoulders conjoin at the junction with the plain hallmarked ring shank.

The trilogy engagement ring is hallmarked to the interior of the shank with the maker's mark for 'Exchange Findings Ltd' (EF Ltd), the Sheffield Assay Office hallmark (rose), the gold guarantee mark (crown), the 18 ct gold fineness mark (750) and the date letter for 1991 (R).

This impressive three stone twist ring is supplied with an independent diamond grading certificate for the centre diamond in addition to an independent diamond grading report card for the supporting stones.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone.

Date: 1991

This 18 ct yellow gold trilogy ring is fine quality set with very well colour matched diamonds.

The ring is a very good gauge of gold and is in excellent condition with very clear hallmarks to the interior of the shank.

Reflections in photographs may detract from the true representation of this fine example of vintage jewellery/estate jewelry.
