Indulge in delectable, guilt-free and luxurious diamond simulants. Our exquisitely hand-crafted diamond simulants showcase the flawless artistry of our highly skilled craftsmen. Our stones are optically similar to naturally mined diamonds, and are indistinguishable to the naked eye.

We are confident that you will love our stones. 


Éclat by Oui is home to those in search for diamond alternatives.

Our stones are precision cut by our master craftsmen and each diamond simulant is polished to resemble the brilliance and fire of a natural, fine diamond.

Every stone is meticulously handcrafted to reveal its captivating, kaleidoscopic brilliance. In fact, many jewellers have difficulty telling our stones apart from naturally mined diamond due to its impressive optical characteristics.

With a hardness of 8.5 on the Moh’s scale, our diamond simulants are comparable to the hardness of a natural Ruby or Sapphire gemstone.
