An engagement ring should carry more than beauty.

It should hold the weight of a promise, the spark of individuality, and the quiet power of a new chapter.

At Kimjoux, we believe timeless does not mean ordinary.

Our rings keep the classic elegance you expect, but are designed with sculptural lines, refined boldness, and personal symbolism that make each piece unmistakably yours.

Petra Ring with Trillion Cut Champagne Diamond

Every detail is intentional: the diamond chosen for its character, the curve that reflects your journey, the engraving that carries your words.

This is jewellery you live in and eventually pass on - a keepsake that speaks of love, commitment, and meaning.

"Worked with Trang Do on a few bespoke pieces to bring back to life old gems I love that ethics are strongly incorporated in the materials she uses! My pieces are everything I hoped for!"

"Thank you so much for repairing my diamond cross pendent necklace. I went to TWO high street well known jewellers and they both said it was not repairable.
You are truly worth your ‘weight in gold’

Highly recommend Trang Do from Kimjoux for design of bespoke gems and repairing those loved pieces."
