All about lab & love grown diamonds

Are lab-grown diamonds real?

A lab-grown diamond is exactly what it sounds like, which is a real, authentic diamond that is formed with scientists duplicating nature’s process above ground. A lab-grown diamond is just as real and contains the exact same properties as one that is formed underground. The only thing that makes a lab-grown diamond different from a mined diamond is its origin.

How can a process that can take millions of years occur in a lab? What makes it faster?

Lab-grown diamonds are created with a process that mirrors what occurs in nature, but without the massive environmental and ethical harm. What happens beneath the Earth’s surface is replicated in a lab using advanced technologies. The process takes between six and ten weeks, and yields diamonds that are ready to be cut and polished, then graded and certified by the same gemologists at organizations that certify mined diamonds.

How do lab-grown diamonds compare to real diamonds compositionally and aesthetically?

Lab-grown diamonds are physically and chemically identical to mined diamonds in every way but free of environmental and ethical harm. Lab and mined diamonds use the same IGI certification and inspection process, which includes grading for carat size, cut quality, color, and clarity. Every Great Heights diamond is IGI certified and an SI2 (slightly included) or better — making them eye-clean to the naked eye.

About Proud Diamond

Where are you located?

We are located in Montreal, Canada.

​​who is behind proud diamond?

Say hi to Virginie.

Like most cool stories, hers started decades ago with her grandpa, Marcel Dumontet, a Manufacturer Sales Agent in the gold and diamond industry since 1963. Growing up under his wing, Virginie was embedded in the diamond business from an early age - learning firsthand of its impact and importance. The natural step to follow his lead happened 30 years later with the (proud) birth of Proud Diamond.

Where do your diamonds come from?

There are less than 50 laboratories in the world at this time. Creating diamonds is one of the more complex process in the world. We have found some in United States, Europe, China, Russia and India. After a very deep research to find the best partner with the same values than us, we have decided to buy mainly in India. Their technology is strong, and we have created a strong relationship with our vendors.
BUT, our vision is to have our own laboratory in Canada one day. We are working very hard to make this vision a reality.

Who makes your jewelry?

All of our pieces of jewelry are made in Montreal, Canada. It’s all handmade, no machine here. We can then guarantee the best quality so you can pass your piece of art from generation to generation.

Who designs your jewelry?

Virginie Roy, the founder, designs all of our jewelry in collaboration with a master jewelry designer. She has a strong knowledge of trends and fashion. She is inspired by films, climate, street, influencers, magazines, fashion designers, creative explorations, political, economic and social. She is obsessed by data, and use it to predict what will become the new trends.
For the first collections, Virginie has created essentials to put the diamond before the design. She thinks that putting the diamond in the middle of the story is how she can educate people on lab-grown diamonds so they understand the importance of changing our behavior to adopt a more sustainable purchase behavior. Wait for the next collections, she can’t wait to put her creativity into it! Or try the custom design service, this is where she can get the most creative to achieve what you have in mind.

We use the CAD Design technology to simulate exactly what our customer have in mind and we change every details until it is perfect. Custom Jewelry can be finish in 2-4 weeks, depending of complexity.

What’s the benefit of buying diamonds online versus in person?

The modern consumer shops online. Starting as brick and mortar would limit our customer interactions, where we can immediately access them digitally. We are also able to provide better prizes since we don’t have to include our loan in the jewels price. Proud Diamond services exceed the in-store experience. We eliminate the jewelry counter intimidation while providing an unprecedented level of customization in lab-grown diamonds and bespoke engagement ring creation.

How much more affordable is a Proud Diamond diamond than a mined diamond?

The price differential varies depending on the size and quality of the stone, but Proud Diamond is 40 to 60 percent less than a comparable mined stone. Proud Diamond has sold the biggest lab-grown diamond ever sold in America. Why? Because the mined equivalent would sell for millions at the big auction houses. Larger, or the more rare, the higher the ‘discount’ from mined pricing.

What's next?

The future is bright for Proud Diamond. Awareness and demand for lab-grown diamonds has grown significantly over a short period of time. Proud Diamond owns one of the largest selections of lab-grown diamonds, so we are a leader in the category in developing and customizing products for our consumers. In 2023, we will be launching more fashion-based jewelry categories, exploring retail concepts, and looking beyond selling in North America.

Practical information

How to clean my jewelry?

We offer a service of cleaning. If you have a ring, we recommend to have the prongs verify at least once a year. You can take the opportunity to have your jewel cleaned at the same time.

For simple cleaning, you can clean your jewelry with mild dish soap and warm water. Fill a bowl with warm water, add dish soap and your jewelry, let it soak for 30 minutes, and then air dry it. For an extra clean, use an unused toothbrush and gently brush your jewelry.
