We absolutely adore this 18ct Gold natural Sapphire Diamond cluster ring. The piece boasts a large natural blue Sapphire at her centre, haloed by twelve rose cuts of Diamond for a twinkling masterpiece!

The ring possesses an undeniable elegance, and we love the royal blue hues from the Sapphire combined with the peppery Diamonds. The ring band is 18ct Gold, whilst the shoulders are Platinum, making this a suitable piece to wear as an engagement ring!

VERY GOOD. This 18ct Gold natural Sapphire Diamond cluster ring is in very good condition. The gemstones are all secure in their settings, and the settings are all intact, with no claws missing. The ring band is robust, and has a full set of hallmarks, although we think they were added at a later date and the ring is actually older! There is very little wear to the piece overall and we think she is a stunning all rounder.
