The star of the show! I think all opal lovers will recognise what an exceptional piece this is. 
 
There are 4 opal hearts with such a superb display of colour, it is quite breath-taking. The base tone is blue, with vivid patterns of yellow, red, orange and flashes of green and purple as you move it. The hearts are separated in a kiss shape with 5 old cut diamonds, in cut down collet settings, the centre being slightly larger than the other 4. They are bright and lively with some small natural inclusions seen with a loupe. 
 
The whole piece is in excellent condition, we have added a new jump ring through an existing eyelet on the piece, so that it is now wearable as a pendant. 10/10, no notes!
