What our customers say

Sara Turner

Judith was so amazing at helping my partner choose an engagement ring for me. They even got the size perfect! Judith was also so helpful after I got the ring by telling me about how to care for it & all the services that Rocks offer with cleaning & serving it to make sure the diamond is secure. I would definitely recommend Judith to anyone. She was very patient with all my questions & eased all my anxiety around wearing such a fab piece everyday like about how to insure it & when to resize it if I needed. She was amazing

Liam Purcell

We had a fantastic experience with Rocks. The staff across their locations in Stillorgan and Grafton Street were great and enabled us to find the perfect ring for us. Jean was our attendant and she was very informative, provided great advice and was very warm and friendly throughout. We couldn't have asked for better customer service... I guess you could say Jean ROCKS!

Thank you Jean and thank you Rocks for everything, I would recommend to anyone and everyone looking for fine quality jewellery and model customer service!

Kev Dowling

Absolutely phenomenal service - Eimear went above and beyond in ensuring the whole experience was exceptional. Couldn't recommend them highly enough, wonderful!

Evelyn Whyms

We dealt with Carol in Rocks on Grafton St. She was extremely helpful and gave us lots of time. I wouldn’t hesitate in recommending Rocks to anyone. My ring was resized within an hour. We will be back for wedding bands!

Ireland’s lab grown diamond specialist

Here at Rocks Jewellers, we specialise in providing our customers with access to the highest quality lab grown diamonds for their engagement rings. Lab grown diamonds possess all the same desirable qualities and characteristics as an earth mined natural diamond, with the one difference being they are created in controlled laboratory settings. To find out more about how these beautiful stones are formed, be sure to read our guide

Due to this one difference, lab grown diamonds are much more accessible than natural stones, which also impacts their price. It is far more likely you’ll find the ring of your dreams within your budget in our lab grown collection than any other range. 

Each one of our lab grown diamonds is graded by the same world-renowned labs that certify earth mined diamonds, so you can be confident in the quality and authenticity of your purchase from Rocks. 

What are the advantages of buying a lab grown diamond?

The most significant benefit of buying a lab grown diamond ring is the incredible savings you can make. In fact, lab grown diamond engagement rings can cost up to 50% less than a style with a natural diamond, while optically, chemically and physically there will be no difference.

Additionally, lab grown diamonds are deemed more sustainable and eco-friendly than earth mined stones, making them the perfect choice for ethically minded customers. 

Just like any diamond, laboratory grown diamonds can be cut, set and styled in many ways. Therefore, you can find everything from solitaire and halo setting or cushion, round and pear cut styles, among many others within our collection. 

Discover our lab grown diamond ring collection 

Our collection of lab grown diamond engagement rings caters to a multitude of styles, personalities and preferences. For example, you can find traditional styles such as an oval cut diamond in solitaire setting, like our Bella ring, as well as the modern day classic round brilliant cut in halo setting

Many of our engagement rings are also customisable, enabling you to add a personal touch to your proposal. For instance, you can choose from a variety of premium quality metal types, such as white and yellow gold, depending on your or your partner’s preferences.

Frequently asked questions 

When it comes to buying an engagement ring, it’s only natural that you will have a number of questions in order to help you make the right choice. Therefore, we have provided answers to some of the questions we are most commonly asked about our lab grown diamond ring collection, which you can read below. 

Are lab grown diamonds as valuable as natural diamonds?

As natural earth mined diamonds are rarer than laboratory grown diamonds, and require a more lengthy and intensive process to form and then be mined, they are deemed more valuable in monetary terms. However, the sentimental value of your engagement ring is just as significant, no matter whether the diamond is earth mined or lab grown. 

Why are lab grown diamonds cheaper than natural ones?

Lab grown diamonds are created in controlled settings and take much less time to form. Therefore, these types of diamonds are much more accessible than natural stones, which enables jewellers to price them at a lower rate. 

Can you tell the difference between lab grown and real diamonds?

Optically and physically, lab grown and earth mined diamonds are the exact same. However, as the value of the two types of diamonds can vary significantly, it is important that you obtain a full certificate with your purchase which outlines the type and grade of the diamonds in your ring. 

Are lab grown diamonds certified?

Yes, lab grown diamonds can be certified by the same world-renowned labs that grade natural diamonds are. All of our lab grown diamonds have been evaluated by an independent company or our own in-house experts, who assess the cut, carat, colour and clarity of every stone.
