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.

Frequently Asked Questions

How are lab grown diamonds made?: Lab-grown diamonds are made in a laboratory by replicating the natural process that forms diamonds in the earth’s crust. Scientists will begin with a small ‘seed’ of a natural diamond, subjecting the small piece to extreme heat and pressure in a special chamber – simulating the natural process, which causes the atoms to rearrange into the same crystal structure as if it were naturally developed. This process can take weeks, or in some cases, months for the lab grown diamond to grow, depending on size. Once it is finished growing, the diamond is then cut and polished, just like naturally-formed diamonds.
Can you tell if a diamond is created in a lab?: There is a common misconception that you can tell just by looking at a lab created diamond that it is ‘fake’ or not a natural diamond. This is not true. To the naked eye, lab grown and traditional diamonds are physically and visually identical. Under close examination and if the diamond is cut, a jeweller may be able to tell the difference between the two. But if you’re looking over at your friend’s new engagement ring – you won’t be able to tell if it has been created with man-made or mined diamonds!
Where can I buy lab grown diamonds in Australia?: With GS Diamonds! We are Australia’s leading provider of lab grown diamonds – you can shop loose diamonds, lab grown diamond jewellery, or create your own custom engagement ring with a man-made diamond through GS.
How are lab grown diamonds certified?: Lab grown diamonds are certified through GIA certification. In order to be certified, diamonds must go through a rigorous testing process to ensure it meets the strict requirements of GIA. GIA has only recently begun to certify lab grown diamonds in the same way that natural diamonds are certified. Previously, lab grown diamonds were only every certified by grading categories. That being said, lab grown diamonds will be graded differently to mined diamonds. This is because there can be subtle differences between the two, such as slight variations in colour or clarity. These variations are not detectable to the naked eye but may affect the grading of the diamond.
Should I shop online or in-store for lab-created diamonds?: Whether you purchase your lab grown diamonds in Australia online or while visiting a certified jeweller is completely up to you. We can help you to find the perfect diamond online, over the phone, or within one of our retail stores in Sydney and Brisbane. Most of our customers will browse one before coming in-store to check out the range in person. Whether you’re looking for loose diamonds, diamond jewellery, or a custom designed lab grown engagement ring, we can help you to find the piece that suits your style, budget, and aesthetic.
