Lab-Grown Diamond Jewellery in Ottawa
Ottawa - and just across the river, Gatineau - is a city that weighs decisions carefully. Lab-grown diamonds fit that mentality: a considered choice that holds up to scrutiny, with clear certification and honest pricing. The bilingual storefront at carattheory.com/fr serves the Francophone side of the river equally.
What the local market looks like
Jewellers around Rideau Centre and Sparks Street typically carry a mix of traditional diamond jewellery and, increasingly, some lab-grown options. In-store lab-grown selection is often limited compared to what an online buyer can access, and the pricing layers reflect retail overhead that an online direct-to-consumer brand does not carry.
Ottawa's bilingual character is reflected in our storefront - the full Carat Theory experience is available in English and French at carattheory.com/fr. Gatineau buyers shop the same collection, same shipping terms, same service.
What every Carat Theory piece includes
- Clear IGI certification. Diamonds over 0.50 ct carry their own certificate; smaller accent diamonds are certified together at the jewellery level.
- Solid 14K gold. No plating. Settings are built to wear, not to look good once.
- Free shipping. To your door in Ottawa, no hidden costs or cross-border surprises.
- 14-day returns. Decide at home, on your own timeline. Returns are fully free.

What is a good diamond necklace to buy as a gift in Ottawa?
Our solitaire pendants are among the most gifted pieces - a single IGI-certified lab-grown diamond on a solid 14K gold chain. Clean, personal, and at a price that reflects the stone rather than a retail margin. Gift packaging included with every order.
