About POLAR
POLAR Lab Diamonds focuses on a fully custom, high-end experience without traditional retail markups. The emphasis is on craftsmanship, precision, and a more personal process.
Every ring is designed collaboratively. From the diamond to the setting, each detail is tailored to reflect your exact vision.
POLAR also prioritizes transparency and value. Lab-grown diamonds deliver the same brilliance, with a modern approach and more accessible pricing.
A Modern Alternative to Traditional Jewelry Stores
Unlike big-box jewelers in Yorkdale or the Eaton Centre, POLAR Lab Diamonds focuses exclusively on custom lab-grown diamond engagement rings.
That means:
-
No mass-produced inventory
-
No sales pressure
-
No inflated pricing
Instead, you get education, guidance, and transparency.
Designed for Toronto’s Style-Conscious Couples
From minimalist Queen West aesthetics to classic Forest Hill elegance, we create rings that match your personal taste.
Popular styles among Toronto clients include:
-
Oval solitaire with hidden halo
-
Emerald cut in platinum
-
Radiant cut with micro-pavé band

East-west set elongated diamonds
Every ring is crafted specifically for you.
Premium Lab-Grown Diamonds
Our diamonds are:
-
IGI or GIA certified
-
Excellent cut grade
-
Eye-clean clarity
-
Ethically created
Lab diamonds are physically identical to mined diamonds — even expert gemologists need specialized equipment to distinguish them.
Transparent Pricing in Toronto
Toronto retail pricing can be steep. We operate differently.
Because we work directly with diamond producers and minimize overhead, our clients often receive:
-
2.0–3.0 carat center stones within mid-range budgets
-
Higher color grades for the same spend
-
More flexibility in customization
We’ll explain pricing clearly — no surprises.
