1. Lab Diamonds are eco-friendly

It depends on how you look at it. They don’t require mining, which can be harmful to the environment. But the process of growing them does use quite a bit of energy. And we don’t yet know what the long-term effects of growing diamonds will be on the environment. So, lab diamonds are a more environmentally friendly option than mined diamonds, but they’re not perfect.

2. They don’t come with baggage

Mined diamonds often come with a lot of baggage. They may be conflict diamonds, which means they were mined in an area where there is fighting going on. They may also be blood diamonds, which means they were mined in conditions that are unsafe and workers are paid very little. Lab diamonds don’t have that baggage. But they also don’t have the positive social impact of supporting millions of livelihoods around the world like mining does. So, lab-grown diamonds are more socially responsible than mined diamonds, but again, they’re not perfect.

5. Lab diamonds are unique

Some people swear that the beauty of a natural, mined diamond is in its utter uniqueness. And that lab created stones just don’t have that. But they couldn’t be more wrong. Every lab diamond is grown individually, just like diamonds from mother nature, and has its own personality, color and inclusions. No two are exactly alike.

What are lab diamonds?

Lab diamonds, also known as man made or cultivated diamonds, are real diamonds that have the same physical and chemical properties as natural diamonds. Just like natural diamonds, they are composed of carbon atoms arranged in a lattice structure.

They are optically, thermally, and physically identical to natural diamonds grown deep in the Earth. The only way to tell a lab grown diamond from a natural one is with very specialized equipment that can detect the minor differences in crystal growth.

The difference between CVD & HPHT diamonds

Lab diamonds are created using one of two methods: CVD (chemical vapor deposition) or HPHT (high pressure high temperature). In both cases a small diamond seed is placed in a chamber where it is subjected to intense heat and pressure. This environment causes the carbon atoms to bond and grow into a larger diamond, which then follows the same process as natural diamonds.

Chemical Vapour Deposition Lab Diamond

CVD is the most common method used to create lab grown diamonds. A small diamond seed is placed in a chamber and exposed to a carbon-rich gas. The gas is then ignited, causing a reaction that creates a layer of diamond on the seed. This process is repeated until the diamond is complete.

High Pressure High Temperature Lab Diamond

HPHT lab grown diamonds are created using technology that replicates the conditions under which natural diamonds are formed deep within the Earth. A small piece of carbon is placed in a pressurised chamber and exposed to temperatures of around degrees Celsius. The extreme pressure and heat causes the carbon to crystallise, forming a lab grown diamond.

Which should I buy?

The choice between CVD and HPHT lab grown diamonds is a personal one. Both types of lab diamonds have the same physical, chemical and optical properties as natural diamonds.

CVD grown diamonds tend to be less expensive than HPHT grown diamonds. This is because the CVD process is less energy intensive and can be run continuously, meaning more diamonds can be produced at a lower cost.

CVD diamonds are usually larger than HPHT diamonds. This is because the size of the seed used in the HPHT process limits how big the diamond can grow. Both types of lab created diamond are graded using the same standards as natural mined diamonds by independent grading laboratories.

The drawbacks of lab diamonds

The only real drawback is if you’re looking at them from a traditional perspective. They are not as rare as natural diamonds and they don’t have the same historic value. If you’re looking for an investment piece, then lab created diamonds might not be the right choice. They are a product of technology, not nature, which for some people lacks emotional punch. Lab diamonds don’t currently have inherent positive social impact nor do they support millions of livelihoods and there is a lack of transparency in how much energy they use to produce.

How to buy lab created diamonds

SJ Gems have gone even further with their lab diamonds. To ensure that you are purchasing a quality product, our stones are all laser engraved with the serial number of the certification. This will ensure your piece of mind that you are getting exactly what you bought.

When you’re looking for lab diamonds, it is important to do your research and make sure you’re buying from a reputable source. Look for a company that can provide certification for the diamonds you’re interested in. This will help ensure that the diamonds are high quality and conflict-free.
