A tangible symbol of commitment, devotion and affection.

Inspired by macramé, an age-old knotting technique used in making friendship bracelets, the KNOT Alone® Collection is a representation of a lasting and unbreakable bond.


"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.

Ethel Neo - Founder of Eclat by Oui

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.
