Leading lab-grown diamond companies

Like Rihanna and celebrities like Lady Gaga, Middle East women love their bling. And diamonds, well the bigger, the sparklier, the better. But what’s a woman to do after she’s told her sheikh boyfriend in Dubai that he can’t keep the pet cheetah? Or the white gold Mercedes running on regular old gasoline? She’s going to have to make new and improved choices when it comes to jewellery. And we don’t mean jewellery made from butterflies or jewels made by bugs


Blood diamonds, or diamonds mined from countries that use slave labor and low wages to harvest diamonds are out. Vintage diamonds are in, but if you want maximum bling and want to buy a few carats, your best bet in style and cut will be a lab-grown diamond.

My small-town jeweller in Ontario, Canada says that he can’t tell the difference and will only buy lab-grown diamonds after his mined diamond stock runs out. Bigger diamonds are preferred and the biggest, unless you are married to the prince of Saudi Arabia, will be out too. 

So we thought to bring you some solid choices from companies around the world who grow their diamonds in a lab. You can shop in person or online for your ring, and some if they know what they are looking for and can be guaranteed a good return policy, can even buy on shops like Amazon. Lab-grown diamonds are known by different names: cultured diamonds, man made diamonds, synthetic diamonds are a few. A carat and a half of a synthetic diamond (1.5 carats) starts at $2000 USD, so don’t expect cubic zirconium prices.

We are talking about real diamonds, made in a laboratory under pressure, in a week and a half inside a large appliance with conditions that are just like in nature, but sped up with the help of pressure.

Some of the companies that manufacture lab diamonds sell only directly to shops or wholesalers while others sell directly to the consumer. Large and important purchases are probably best made in person, while sizing your ring. But we know that people trust online shopping so the below list includes wholesale companies as well as those who do direct to consumer purchases. 

Clean Origin

Clear Origin is a US based company that lets you customize size, cut clarity, setting and a pile of other things that might be important to you. This company sells directly to consumer and the price range for a round, 1/5 carat in a gold setting is about $1500 USD.

Vibranium Lab is a London-based company that also does direct to consumer shipping, with a list of customizable details that you can select. The cost for a 1.5 carat round diamond is about $2500 USD. Being in a central hub likes London makes it easier for returns or changes in settings.
