Honesty, quality and service are at the heart of everything we do.

How it began
Louèn Diamonds was founded in 2025 with one clear goal: to make luxury jewellery more accessible in a modern way. After years of experience in the traditional jewellery and fashion industries, we saw that things could and had to be done differently. More transparent, more sustainable and more customer-focused.
We began our journey by carefully selecting high-quality lab-grown diamonds and combining them with timeless designs in 14k gold. We consciously choose a compact and clear collection to make selecting jewellery easier for our customers.
Today, we have a dedicated team in Haarlem and suppliers who are just as committed to delivering quality as we are. Every day, we work with passion on creating beautiful jewellery for our customers, offering the personal service of a small team with the professionalism of a larger brand. And so, we continue to build our brand step by step.

Zeer vriendelijke hulp via de chat heeft mij overtuigd en ben goed geholpen.
Ik ben zeer tevreden met de kwaliteit. Het is een stevige ketting met stevige hanger. De steen glimt enorm.
De oorbellen werden snel en net op tijd geleverd voor pakjesavond. Mijn vrouw is er zeer gelukkig mee
Het collier is in een dag geleverd nadat ik dat heb gevraagd. geweldig cadeau en super shiny.
Het perfecte cadeau - ze is er superblij mee en het glimt nog meer dan verwacht
Fantastic! I hesitated for a moment about this site, but I’m honestly so incredibly happy with my ring. Thank you
Ik bestelde zelfde producten maar hier is echt goedkoper voor hetzelfde.
Heb veel contact gehad omdat ik twijfelde aan de webshop. maar ben goed geholpen en via creditcard verzekerd betaald. mijn twijfel was niet nodig want ben heel blij met mijn oorbellen
De oorstekers zijn precies zoals op de foto. Lichtgewicht, mooi glanzend en passen bij alles. Echt blij mee.
Dit kettinkje gekocht voor mijn vriendin. Pakketje was netjes verpakt en ze was er superblij mee. De diamant oogt helder en van goede kwaliteit.
An amazing shine and a truly beautiful piece that I’ll enjoy for a very long time. After all, you are what you wear.
Ik was verrast hoe snel het binnen was in 2 dagen. De ring is fijntjes maar voelt toch stevig aan. de diamant is prachtig en echt groot. Ik krijg er veel complimenten over.
Ik twijfelde eerst omdat het mijn eerste lab-grown diamant was. Maar wow… wat een schittering. De oorbellen zijn subtiel en toch heel chic. Ik zou hier zo weer bestellen, want het is een perfect cadeau!
Het armbandje ziet er supermooi uit. De afwerking is echt mooi en het voelt heel luxe aan. Ik draag hem nu een week elke dag en hij blijft schitteren.
