A lab-grown diamond is precisely that, a diamond.  

The difference lies in the growth process. Natural diamonds are unique in that they have formed over a billion or more years in the earth. Lab-grown diamonds are grown under highly controlled laboratory conditions that replicate the Earth's natural growth process of crystallising carbon. Using specific technology that uses temperatures, gases, and pressures, gemstone quality diamonds can be formed in a lab over a matter of months. This means each lab-grown diamond will have variation in appearance and grading, just like diamonds formed naturally.  

Chemically, optically and physically, there isn't a difference between lab-grown and natural diamonds.  

They are graded on the same scale, and have exactly the same physical properties.

The only difference is the growth process, and the price. Lab-grown diamonds are significantly less expensive than natural diamonds.

We always recommend having your ring size professionally measured, as this is the only truly accurate way to gauge your size. Ring sizing is very accurate (down to fractions of millimetres).

If you’re able to visit our Sunshine Coast locations, you can have your ring size measured at our Noosa Flagship (no appointment necessary), or by appointment at our Peregian Beach showroom.

Alternatively you can seek out a trusted jeweller local to your area to have your ring size measured. This should be a complimentary service offered by most reputable jewellers.

We offer a complimentary Ring Sizer which you can use to measure your finger (Australian clients only). This is a good starting point if you’re not able to visit a jeweller - but keep in mind that it will not be as accurate as a professional measurement.
