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.

This 1920s ring is excellent quality, set with an impressive feature diamond displaying a fine white colour, brilliance and presence.

The impressive supporting diamonds display a fine white colour and brilliance.

The ring is an excellent gauge of platinum and is in excellent condition, with a clear hallmark to the interior of the shank.

Reflections in photographs may detract from the true representation of this fine example of 1920s jewellery.
