Lab-grown diamonds are real diamonds created using advanced technology that replicates the natural diamond-growing process. They offer the same beauty, durability, and brilliance as mined diamonds while providing exceptional value.
Lab-Grown Diamonds vs. Natural Diamonds
Both are real diamonds. The difference is origin: natural diamonds form underground, while lab-grown diamonds are created in a controlled environment.

| Each has a distinct geological origin | Produced in a range of sizes and qualities | |

Diamonds Canada FAQs
Are lab-grown diamonds real?
Yes. Lab-grown diamonds are real diamonds with the same chemical, physical, and optical properties as mined diamonds. They offer the same brilliance, durability, and beauty as natural diamonds.
What are the 4Cs of diamonds?
The 4Cs are cut, colour, clarity, and carat weight. Cut affects how much a diamond sparkles, colour measures how colourless the diamond appears, clarity refers to natural inclusions or blemishes, and carat weight measures the diamond’s size by weight. Understanding the 4Cs can help you compare diamonds and choose the right option for your jewellery piece.
Are natural diamonds more valuable?
Natural diamonds are rarer due to their geological origin, while lab-grown diamonds generally offer greater size and quality for the same budget.
Do you sell natural and lab-grown fancy coloured diamonds?
Yes. Jacob Mercari offers natural and lab-grown fancy coloured diamonds in hues such as yellow, pink, blue, green and brown, depending on availability. Shop our loose coloured diamonds online to compare shapes, carat weights, colour intensities and prices. For personal guidance, book a private appointment at our Toronto studio or connect virtually to explore your options.
Can I book a private diamond consultation in Toronto?
Yes. Jacob Mercari offers private consultations by appointment at our Toronto studio. During your consultation, our team can help you compare natural and lab-grown diamonds, understand diamond grading reports, choose a diamond shape, and explore custom engagement ring or fine jewellery options.
Can I choose a diamond online and have it set into a ring?
Yes. Select a loose diamond online and pair it with an engagement ring setting using our ring builder. Your chosen diamond can also be incorporated into a custom ring, pendant, earrings or another jewellery piece. Our Toronto team is available to help you select a setting that complements your diamond, style and budget.
What diamond shape looks largest for its carat weight?
Elongated diamond shapes often appear larger than round diamonds of the same carat weight. Oval, pear, marquise, and emerald-cut diamonds can create a larger visual presence because of their length and surface area. The best shape depends on your style, setting, and budget.
Do you offer free shipping?
Yes. We offer free insured FedEx shipping across Canada and the USA for all orders over $400. For orders under $400, a flat shipping fee is applied at checkout, which still includes full insurance and tracking to ensure your jewellery arrives safely.
