The Lapis Lazuli we use in our gemstone mosaic cufflinks is reconstructed Lapis Lazuli. This is a method of reconstructing the Lapis with a blend of polymers and resins to create a much more stable stone for use with other stones in the mosaic cufflinks. It also gives the stome a striking strong uniform blue colour. Our cufflinks that are entirely Lapis however, all use natural Lapis Lazuli, and as such, there is a variation in the stone which means every pair of these cufflinks will be different.
