lab grown diamonds

Lab grown diamonds are made safely with sustainability in mind. Because we do not mine our diamonds we do not harm the environment and are conflict free.

science & sparkle

Lab-grown diamonds share the same physical, chemical and optical characteristics as rare, natural diamonds.

But the process needed to create them is different from nature, so while they are neither as valuable or precious, they are just as sparkly.

brilliant stuff

Put a tiny piece of lab-grown diamond, rather like a seed,into a plasma reactor. Then heat that plasma to 4000 Kelvin (over 6000 degrees Fahrenheit)

jewel or tool?

The very same lab-grown diamond can be used in many cutting-edge technologies.

From today’s finest audio systems to tomorrow’s quantum computers.

choose your color

We can play with chemistry, time and temperature to make a lab-grown diamond in different colors. So you can choose a jewel in blush pink or powder blue.

time and again

We monitor quality all the time as each solitaire is cut to our demanding standards. We want every Lightbox lab-grown diamond to sparkle just like the next.
