Lab Grown Diamonds Sydney

Sydney’s Best Range of Lab Grown Diamonds

When it comes to finding the best lab grown diamonds Sydney has to offer, GS diamonds are the only choice. Lab grown diamonds, also known as man-made diamonds or synthetic diamonds, are real diamonds that have been created in a laboratory. Just like natural diamonds, lab grown diamonds are made of carbon – however the process to create them is very different.

Natural diamonds are formed over millions of years deep within the earth’s crust. Like the saying goes, diamonds are made under extreme heat and pressure which creates a sold, unbreakable exterior. Lab grown diamonds, on the other hand, are crafted using state-of-the-art technology that aims to exactly replicate the conditions under which natural diamonds are formed.

Over the last decade, GS Diamonds has been at the forefront of lab grown diamond technology with a growing range of lab grown diamond alternatives across every range in our collection. Buy online or visit our Sydney showroom at the Queen Victoria Building at 455 George Street, Sydney, Australia.

Exceptional Beauty, Outstanding Value

When it comes to finding the perfect diamond, many people think traditional is the only way to go. Today, more and more people are choosing lab grown diamonds as a stunning, viable alternative to traditionally mined diamonds. Our range of lab grown diamonds in Sydney are created in a laboratory setting using cutting-edge technology.
So, why are so many people now choosing lab grown diamonds?

One of the key advantages of lab grown diamonds over natural diamonds is that they are more environmentally friendly than their natural counterparts. The process of mining and extracting diamonds takes time, effort, and processes that are simply not required to create natural diamonds.

Additionally, lab grown diamonds tend to be less expensive than natural diamonds which means you are getting a larger, clearer stone for the equivalent price. Because the process of creating lab grown diamonds in Sydney is more efficient and there is no need to pay for the mining and labour of extracting diamonds, lab grown diamonds offer excellent value for money.

Remember, if you see products online claiming to be an alternative to natural diamonds, that does not mean that they are of the same quality as lab grown diamonds. Products which are sold as cubic zirconia, synthetic diamonds, moissanite, or eco-friendly diamonds are not lab grown diamonds. Lab grown diamonds are a genuine natural alternative that offer all of the natural beauty of traditional diamonds, at a more competitive price point.

If you’re looking for a diamond that makes a statement in an engagement ring, wedding ring, loose diamond, pendant, or earrings, then lab grown diamonds are a great alternative.
