This stunning ring features a scintillating 5 carat Autumn tourmaline. The stone shifts between shades of forest green and autumn orange, depending on the light and angle it's viewed from. The 18ct rose and yellow gold setting helps accentuate the warm orange hues in the stone, with 12 surrounding diamonds to add that extra sparkle. 

This is a one-off stone set in a bespoke design by Travis Trewarne.
