Are lab-grown diamonds the same as real diamonds?

Lab-grown diamonds are identical to mined diamonds sharing the same physical and optical properties. Both are forms of crystallised carbon and exhibit the same fire, scintillation, and sparkle. The biggest difference is that lab diamonds are grown in a much shorter time to form than their natural counterparts.

Do lab grown diamonds come with a certificate?

Yes, our lab-grown diamonds are accompanied by a certificate of authenticity issued by one of the leading diamond grading laboratories including IGI, GIA and GCAL.

Are lab grown diamonds ethical?

At Larsen Jewellery, we proudly align ourselves with growers that are ethically responsible. This ensures that our diamonds comply with the highest ethical standards.

How are lab grown diamonds graded?

As they have the same chemical and physical properties, lab-grown and natural diamonds are graded in the same way. They're assessed on the same 4Cs as the major international grading laboratories (cut, colour, clarity and carat).

Are lab grown diamonds better for the environment?

While lab-grown diamonds may not have the same environmental impact on the earth as mined diamonds, they still require a lot of energy to produce. Our preferred suppliers are committed to using clean, renewable energy including hydro and solar power to grow their diamonds, minimising their environmental footprint, making them an environmentally conscious choice.

Can you tell that a diamond is lab grown?

No, to the naked eye, it is not possible to tell the difference between a lab-grown diamond and a natural diamond. Only an experienced gemmologist, with specialised equipment, can distinguish the difference.

What Are Lab Grown Diamonds?

There are two common ways Lab grown diamonds are created. Both are produced in a controlled laboratory environment. The first method is HPHT which stands for High Pressure, High Temperature. This technique simulates the extreme heat and pressure of the earth’s mantle. The other method is CVD which stands for Chemical Vapour Disposition. CVD diamonds are grown with less pressure and heat with the aid of carbon rich gasses. Both types of laboratory grown diamonds are chemically identical to mined diamonds. This means they share the same physical and optical properties. They exhibit the same fire and sparkle as mined diamonds and are graded using the same 4Cs as the major grading laboratories.

I'm a returning customer to Larsen Jewellery, Sydney and once again it was a lovely experience. I was looking to purchase a tennis bracelet and met Soukata who was great to deal with, she was very helpful, knowledgeable and completely understood exactly what I was looking for. I'm more than happy with my beautiful bracelet. Thanks Larsen. Cathy
