Lab-Grown Diamonds

Lab-grown diamonds are chemically, optically, and physically identical to naturally occurring diamonds and the hardest of all gemstones. We love using lab-created diamonds in engagement rings and tennis bracelets or other jewellery that sees heavy use since they retain their brilliance, fire and scintillation better than other gemstones. Colored gemstones, such as rubies, sapphires, and emeralds, aren’t as hard as diamonds, which are a 10 on the Mohs hardness scale. Diamonds can be worn for a lifetime and maintain their brilliance throughout. If you’re looking for a lasting gemstone choice for yourself or a loved one, created diamonds are one of your best options.

We hold all of our created diamonds to the same standards as our mined diamonds, though you may find that the price comparison differs between the two. Labs have refined their processes to create higher-quality diamonds while keeping prices lower than natural diamonds. You can also find created colored diamonds in hues of yellow, blue, and pink in addition to clear.

Using lab-grown diamonds in engagement rings is a very popular recent trend for a variety of reasons. The cost and increased inventory at affordable prices make them a perfect option if you’re looking to tie the knot or find the perfect gift. The hardness of a diamond cannot be matched by moissanite, cubic zirconia, or any other diamond substitutes!

Our Process

1SELECT DIAMOND SEED

Check for the best quality diamond seed. Put the diamond seed on the metal disk.

2GROW THE DIAMOND

The diamond seed is placed into a microwave plasma chemical vapor deposition chamber. A plasma cell is created out of Hydrogen.

3CUT THE DIAMOND

After 10-12 weeks a rough diamond is created. A laser is used to cut the diamonds.

4POLISH THE DIAMOND

Diamonds are faceted into desired shapes by skilled diamond cutter using the same tools and techniques that are used with mined diamonds.

Commonly Asked Questions

We get a lot of questions about created diamonds. Here are answers to the most commonly asked questions:

Yes! Lab-grown gemstones are chemically identical to naturally occurring diamonds. They are graded the same way that natural diamonds are graded, using the 4 C’s (color, cut, clarity, and carat). Gemological labs with high-powered equipment and specially trained gemologists can tell you if you have a created diamond or a naturally occurring one, but to the naked eye and even under standard microscopes, it is nearly impossible to tell the difference.

Not necessarily. Man-made gemstones are still subject to many of the same flaws and inclusions that natural gemstones are, and diamonds are no exception.

There are two main processes for producing diamonds in a lab. Both are quite technical procedures that require a few weeks to produce results. High Pressure, High Temperature (HPHT) mimics the way diamonds are formed naturally in the earth but speeds up the process exponentially. Chemical Vapor Deposition (CVD) creates these precious diamonds by using a chemical reaction to break carbon molecules apart and reform them into diamonds.

Lab-grown diamonds can go by many different names: engineered diamonds, created diamonds, cultured diamonds, and man-made diamonds all refer to the same process of creating a diamond without mining processes. However, if you see the terms “artificial” or “synthetic” when referring to a gemstone, it might not be a diamond at all. Cubic Zirconia, or CZ, are man-made diamond look-alikes that do not have the same chemical structure as a diamond. Always ask your jeweller for specifics when purchasing fine jewelry to ensure you understand the type of product you’re looking at!
