"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 obsessed with delivering unrivalled quality in the realm of simulated diamonds.

We are confident that you will love our jewellery.


Ultimate in femininity and alluringly romantic, our signature pink stones play muse to some of our most classic pieces. Each stone creates a spectacular show of scintillation. Complemented with impeccable quality, every piece is a marvellous work of art.


The Éclat Difference

Every Éclat by Oui piece is an artwork.

Our stones are precision cut by our master craftsmen. Every stone is meticulously handcrafted to reveal its captivating, kaleidoscopic brilliance. 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.

Perfect for travelling and beyond.

Éclat by Oui first came about when our founder, Ethel Neo, lost her engagement ring in Hong Kong. Disappointed and traumatised, she decided to look into a luxurious yet guilt-free diamond alternative. That was when she saw a gap in the market.


With every order made, we plant one tree.

With 15 billion trees being cut down yearly, reforestation is consistently identified as one of the best solutions to combat climate change. As part of our commitment to sustainability, we are honoured to support reforestation with One Tree Planted.


Inspired by the ageless spirit of modern femininity.

With an emphasis on elegance, refinement and considered details, we want our jewellery to be loved by and lived in. Driven by passion, our team believes that each piece of jewellery is a tangible expression of love or sentiment.
