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.

Why should I buy a lab diamond engagement ring?

Choosing a lab grown diamond engagement ring can offer ethical and environmental benefits.

They share the same physical and chemical properties as natural diamonds, and are subject to our same commitment to sustainability and responsible sourcing.

Do lab diamond engagement rings require special care and maintenance?

Lab grown diamond engagement rings require the same care as natural diamonds. Regular cleaning with mild soapy water and gentle brushing can help remove every day grime, as well as annual cleaning and checks by an expert to help them maintain their sparkle. Ask your jeweller for specific care advice to ensure your ring remains beautiful for a lifetime.
