Lab-Grown Diamond Rings & Wedding Bands: 5 Must-Knows
Lab-grown diamonds are chemically identical to mined stones and cost 60-80% less. Here’s what to know about price, ethics, and value retention before choosing.
If you are shopping for an engagement ring in Toronto right now, one question comes up more than any other: should I choose a lab-grown or a natural diamond? Both are real diamonds. Both are graded by the same labs. And both can be stunning. But they differ in price, value retention, and the story behind the stone. Here is what you need to know before you decide.
What is a lab-grown diamond?
Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. The difference is where they formed. A natural diamond formed deep in the earth over billions of years. A lab-grown diamond formed in a controlled laboratory environment over weeks or months, using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) techniques. Both produce a pure carbon crystal that is, in every testable way, a real diamond.
Price and value retention
This is where the two diverge sharply. Lab-grown diamonds typically cost 60 to 80 percent less than a comparable natural diamond. A one-carat lab-grown in a solitaire setting might run $4,000 to $6,000 in Toronto. The same stone mined would often be $10,000 or more. Natural diamonds have historically held their value better on the resale market, though resale values for both categories are well below retail. If resale is a concern, a natural stone with a strong GIA certificate is the safer choice. If maximum stone size per dollar is the goal, lab-grown wins.
Ethics and traceability
Lab-grown diamonds are conflict-free by definition and generally have a smaller land and labor footprint. Natural diamonds sourced through Canadian Jewellers Association members adhere to the Kimberley Process, which tracks stones from mine to market to prevent conflict financing. We use GIA-certified stones for both categories and can show you the paper trail on any diamond we set.
How to choose between them
There is no wrong answer. A lab-grown stone lets you go bigger, or save the difference for the wedding, the honeymoon, or a down payment. A natural stone carries the romance of a billion-year-old crystal. During your consultation, we will show you both side by side in natural light. Most clients are surprised at how hard it is to tell them apart.
