If you're thinking about buying lab-grown diamonds but are somehow feeling overwhelmed by the options, don't worry! You're not the only one. There are so many types of lab-grown diamonds available today that it can be difficult to know the difference. Not to worry, I'm here to break down the different types of lab-grown diamonds so you can feel more confident in your decision!
Let's make this clear right off the bat: all types of lab diamonds are real diamonds! They are composed of the same material as mined diamonds (carbon) but are grown in a lab rather than dug from the Earth. There are different processes and types of lab-created diamonds, however, that give them slightly different attributes.
1. CVD Diamonds (Chemical Vapour Deposition)
The CVD diamond is one of the most common types of lab-grown diamond.
- How are CVD diamonds created?
CVD diamonds are created by heating carbon gases in a vacuum chamber. The gases will settle down, creating layers of carbon atoms that eventually turn into diamonds.
- Why would you choose a CVD diamond?
Typically, CVD diamonds have fewer inclusions and have a cleaner look. CVD diamonds have a lot of ability to customize cuts and styles, such as making the diamond ring the exact shape you want
CVD diamonds are normally more eco-conscious when using a lab that uses renewable energy
If you include sustainable shopping on your agenda, where clarity is at the forefront, then CVD diamonds are one of the best types of lab-created diamonds you can buy.
2. HPHT Diamonds (High Pressure High Temperature)
However, another one of the main types of lab diamonds is the HPHT diamond. HPHT diamonds are created with a method closely resembling how diamonds form normally.
- How are HPHT diamonds created?
With HPHT diamonds, carbon is melted in a chamber with immense pressure and heat until it crystallizes and forms a diamond.
- Why go for HPHT?
- Faster production speed than CVD diamonds
- Usually has a more "natural" feel
- Slightly warmer, which is nice if you like a bit of color in your stone
If you are looking for a diamond that gives you a traditional vibe but you would like a faster production time, HPHT diamonds are a great option among the types of lab-created diamonds.
3. Type IIa Diamonds (Ultra-Pure Lab Diamonds)
Type IIa diamonds are among the best categories of lab-created diamonds.
- Why are they special?
Type IIa diamonds have extremely low levels of nitrogen or other impurities, so they are very pure and clear. These are the premium models of the lab-grown world.
- Why pick Type IIa?
- Exceptional clarity and brilliance
- Considered rare and premium
- Great for luxury jewellery or heirloom pieces
Type IIa is one of the top types of lab diamonds if you appreciate purity and want a completely flawless diamond.
4. Fancy Color Lab-Created Diamonds
Do you want something other than traditional white or clear diamonds? This is where fancy color lab-created diamonds come in: they shine!
- What is the difference between fancy-color diamonds?
These diamonds are created using processes that either add trace elements or use a treatment post-growth to bring out colors like pink, blue, green, and more.
- Why choose fancy-color diamonds?
- Add a vivid and unique touch to your piece of jewelry
- Less expensive than naturally occurring fancy-color diamonds
- A variety of tones with soft pastels to deep, bold colors
These colorful gemstones are great if you want to have some personality. They are a fun, bold option when considering the types of lab-grown diamonds.
5. Moissanite vs Lab-Created Diamonds
Although Moissanite is not a true type of lab-created diamond, it certainly is compared to lab-created diamonds.
- What is the difference?
Moissanite is manufactured from silicon carbide, not carbon. It sparkles fabulously and is an extremely popular alternative to diamonds, but it is not a diamond.
So, Why Choose These Types of Lab-Grown Diamonds?
- Lab-grown diamonds are chemically identical to mined diamonds
- Lab-grown diamonds are more durable and provide more value long-term
- Lab-grown diamonds are perfect for anyone seeking the full diamond experience
- If you want a true diamond with all it entails, lab-created diamonds are your best bet.
