About Us

"Éclat" means great brilliance and display in French.

Founded in 2017, we are home to those in search of diamond alternatives. Inspired by the ageless spirit of modern femininity, Éclat by Oui is dedicated to the independent, the modern and the beautiful. Our team is absolutely obsessed with delivering unrivalled quality in the realm of simulated diamonds.

We are confident that you will love our stones.


Trees are essential to the health of our planet. With 15 billion trees being cut down yearly, reforestation is consistently identified as one of the best solutions to combat climate change. To mark our commitment in sustainability and reforestation, our team participated in the OneMillionTrees Movement on Earth Day this year.

Moving forward, we will be rolling out more initiatives to make a positive impact to our environment.


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.
