Yes, we do. All engagement ring center stones come with a GIA certificate. These reputable organizations grade and certify diamonds based on their quality and rarety characteristics. We can also provide an appraisal report for the product upon request. We equally offer certification for lab-grown diamonds, which are ethically sourced in Canada.
We take pride in sourcing our diamonds responsibly and ethically. This means that we only work with ethical diamond dealers who are members of the Canadian Jewellers Association (CJA) in Canada. The CJA is a trade association that promotes high standards of professionalism, ethics, and social responsibility in the jewellery industry. By being a member of the CJA, our diamond dealers adhere to the Kimberley Process, an international certification scheme that prevents conflict diamonds from entering the market. Conflict diamonds are mined in areas of armed conflict and used to fund violence. By sourcing our diamonds from CJA members, we ensure that our stones are gorgeous, sparkly, conflict-free, and environmentally friendly.
Our custom lab-grown diamond rings typically range from $4,000 to $8,000, depending on the design, setting, and size and quality of the diamond you choose.
Custom rings featuring natural diamonds usually fall between $8,000 and $20,000. The final cost depends on the diamond’s carat, cut, clarity, and color, as well as your chosen setting and design.
For custom rings with natural gemstones—such as sapphires, emeralds, or rubies—pricing typically ranges from $4,000 to $8,000, depending on the rarity and size of the stone, and the complexity of the design.
From finalizing the design to having the ring ready, it usually takes 2–3 weeks. If you’re working toward a specific date, let us know and we’ll do our best to accommodate.
Our catalogue is limitless, offering access to ethically mined and responsibly sourced diamonds and gemstones of every grade, tailored to suit any style, budget, and preference.
