Tennis Ring with Lab-Grown YAG Paraiba signed Miles Chamley-WatsonTheres a special sparkle in this Messou Jagged Tennis Ring. It could be our unique patented Messou cut, which makes the lab grown YAG Paraiba stones remind us of good times and glistening tropical waters. Or it could be the fact that 'the face of fencing', Miles Chamley Watson, aka @fencer, handpicked the stones while sharing that his ritual before competitions is not to have one, just to be better than last time. Now that's how you create a legacy.
