A well-cut 1-carat lab-grown diamond costs roughly C$950 to C$2,100 in Canada, and a 2-carat stone runs about C$2,500 to C$4,150. That is 81% to 88% less than a mined diamond of the same size and grade. Anyone comparing lab grown diamonds Canada retailers sell will also notice that the same carat weight can vary fivefold in price, and the reasons are easy to check once you know where to look.
Lab Grown Diamonds Canada: Typical Prices by Carat
The table shows retail prices for loose, certified stones in the popular quality band: near-colourless, eye-clean, excellent cut. Prices are shown in US dollars (USD) and Canadian dollars (CAD), as labelled in the column headers. The CAD figures convert the USD estimates at US$1 = C$1.38, about the 2026 average rate, so they are approximate. Savings compare the low end of the lab-grown range with the low end of the natural range, and the high end with the high end (for 5.00 ct, 96.0% and 98.2%).

These are mid-market numbers, and the full market is wider. One large online retailer's Canadian price guide lists 1-carat lab-grown stones from C$500 to C$4,500 and 2-carat stones from C$1,000 to C$13,500. Entry-level 2-carat stones appear in Canada for about C$1,000. At the other end, top colour, top clarity and ideal cut can triple the price of the same weight.
Price per carat tells a second story. With mined diamonds, each carat costs more than the last because large crystals are rare. Lab-grown stones behave differently: one survey puts them near $1,300 per carat at the 1-carat mark and $850 to $900 per carat at 2 to 3 carats. A bigger stone takes more reactor time, but it is no rarer than a small one.
Why Two Stones of the Same Weight Cost Different Amounts
- Cut. Cut quality decides how much light the stone returns, and it is the factor worth paying for. An excellent or ideal cut costs more than a good cut and looks visibly brighter.
- Colour and clarity. D colour and flawless clarity carry a premium you cannot see without magnification. G to H colour with VS2 clarity looks white and clean to the eye and sits at the value point of most price lists.
- Shape. Rounds cost the most per carat because cutting them wastes more rough. Ovals, cushions, pears and emerald cuts of the same weight usually cost less and often look larger.
- Growth method. Stones are grown by CVD or HPHT. Neither is better by default, but side effects matter: a brown or grey tint in some CVD stones and a blue nuance in some HPHT stones lower the price. Ask whether the stone was treated after growth.
- Grading report. An IGI or GIA report adds a little to the price and removes most of the guesswork. IGI reports give full colour and clarity grades. GIA has moved away from that scale for lab-grown stones and now sorts them into two categories, premium and standard. A stone with no report should be priced well below one with a report.
Lab-Grown vs. Natural: How Big Is the Gap?
The gap widens with size. At half a carat, a lab-grown diamond costs about a quarter of the mined equivalent. At 2 carats it costs about an eighth. At 5 carats the saving reaches 96% to 98%.
In practical terms, the budget that buys a 1-carat mined diamond buys a 3-carat lab-grown stone of better colour and clarity. Both are crystallised carbon with the same hardness, brilliance and durability. A grading laboratory can tell them apart with specialised equipment. A jeweller's loupe cannot.
Canadian advertising guidelines keep the two categories clearly labelled. The Canadian Jewellers Association requires the words "laboratory grown", "lab created" or "synthetic" to sit directly before "diamond", with equal prominence. The word "diamond" alone means a natural stone. If a listing is vague about origin, treat that as a reason to shop elsewhere.
The Full Cost: Setting, Tax and Shipping
The stone is often only half the bill. Three more lines belong in your budget.
The setting. A plain solitaire in 14k gold typically adds $300 to $800. A halo or accent setting adds $1,000 to $2,500. Because the stone is so affordable, the setting can account for 30% to 50% of the price of a finished lab-grown ring.
Sales tax. Listed prices in Canada exclude tax. The rate depends on your province:

Buying across the border. A lower US sticker price can disappear at the border. Imports are subject to GST or HST on arrival, the price is charged in US dollars, and finished jewellery may attract customs duty depending on where it was made. Brokerage fees and the cost of returning a stone internationally add to that. For most buyers of lab grown diamonds Canada based sellers work out simpler and often cheaper, because prices are in Canadian dollars, shipping is insured domestically and returns stay inside the country.
Where Prices Are Heading, and What That Means for Resale
Lab-grown prices have fallen steeply for years. Industry analyst Edahn Golan's wholesale index is down 96% since he began tracking it in July 2018, including a 26% drop in 2025. The fall came from scale: producers in India and China added reactor capacity faster than demand grew.
The decline is now slowing. In Golan's second-quarter 2026 wholesale price list (published July 13, 2026), prices for 1-carat rounds rose 1% year over year, while 1.50 to 1.99-carat rounds fell 11% and 2-carat rounds fell 20%. These are wholesale figures, and retail prices for the same stones may move differently. Some growers have raised rough prices by 25% to 30%. Cutting, polishing and certification also set a floor, since those costs do not shrink with better reactors.
A lab-grown diamond is a purchase to wear, not an asset. Resale estimates run from 10% to 30% of the price paid for lab-grown stones (Buchroeders Jewelers and Ben Garelick; see Sources and notes). A mined diamond does better, at 25% to 50% of retail, but it loses far more in absolute dollars. On a C$1,500 lab-grown stone, the most you can lose is C$1,500.
How to Get the Best Value
- Put the money into cut. Choose excellent or ideal cut first, then adjust colour and clarity to fit the budget.
- Stop at G–H colour and VS2 clarity. Higher grades cost more and look the same on the hand.
- Buy just under round numbers. A 0.90-carat or 1.90-carat stone looks the same as a 1.00 or 2.00 and often costs less.
- Consider a fancy shape. An oval or pear gives more visible size per dollar than a round.
- Insist on a report. Match the laser inscription on the girdle to the report number before you pay.
- Compare the total, not the sticker. Add the setting, provincial tax, shipping and the return policy to every quote.
- Check the upgrade policy. Some jewellers credit the purchase price toward a larger stone later, which offsets weak resale value.
The market for lab grown diamonds Canada wide is competitive, so two or three quotes for the same specifications are easy to get and usually reveal the fair price within a day.
