Sounds like the title of a killer sci-fi book!
When we say 'substitutions are available upon request' we mean it! This is our 'Luna' ring substituted with a hexagon. Within the Platinum and Moissanite halo rests a 7mm Arctic Blue 'Cosmos' hexagon. This looks absolutely phenomenal and I can't wait for it to get to it's new home; to be the center of a proposal, to begin the next phase of an enchanting and wonderful life! We have the best job in the world - but it wouldn't be so great without the amazing clients we have!
