At ROCKRUSH we provide the highest quality in Lab-Grown Diamonds. From cultivation to creation, we oversee every aspect of the diamond’s journey, ensuring unparalleled quality and affordability. But what is a Lab Grown diamond, and why have they become such a popular choice for those seeking diamonds? There are many reasons people choose Lab Grown over Natural! Sustainability, affordability, ethics are just some of the benefits of choosing Lab Grown.
Lab Grown diamonds avoid destructive mining processes that can harm both the environment and local communities. The mining of Natural diamonds has been linked to unfit working conditions, forced labor, and other human rights abuses, funding violent conflict in local communities. The mining process also disrupts local ecosystems, encourages deforestation and erosion, and increases water and noise pollution.
Lab grown diamonds avoid destructive mining processes, instead harnessing the power of wind and water - both renewable resources - to provide the electricity required to run the laboratories and CVD machines. By choosing Lab Grown, you can feel confident your diamond is conflict free and promotes sustainable, renewable practices.
By choosing Lab Grown diamonds, you become a conscious consumer, contributing to a more sustainable future and avoiding environmental degradation, habitat destruction and threatening Earth’s essential ecosystems.
What is a lab-grown diamond?
Lab-grown diamonds are grown in highly controlled laboratory environments using technology that duplicates the conditions in which diamonds naturally form under the Earth's crust. They are chemically, optically and atomically identical to mined diamonds except with a different origin story. We've replaced the mines with machines.

Product Care
Caring for your lab-grown diamonds is as important as investing in a quality stone. Although lab grown diamonds are known to be one of the hardest stones, they can be scratched and chipped if due care is not taken. Here’s what you need to do to ensure your jewelry stays sparkling:
-
Remove your jewelry during manual tasks like cooking, cleaning, gardening or moving furniture to avoid any physical damage.
-
Don’t expose your lab grown diamonds to chemicals like cleaning fluids.
-
Wear your jewelry only after putting on your makeup, hairspray, perfumes and lotions. These contain chemicals that can damage or create a build-up on your jewelry.
-
Remove your jewelry before diving into chlorinated water or at the spa. This is because exposure to chlorine weakens a ring’s alloy and can cause structural damage.
-
Avoid contact sports. Any hard blows can be damaging to your lab grown diamonds, so we strongly recommend removing all jewelry beforehand.
-
Wearing two rings on one finger can cause friction and damage. We recommend soldering the two rings together or limiting one ring to one finger.
Cleaning & Care
-
The best tool for cleaning is a soft toothbrush, warm soapy water and a lint-free cloth.
-
Let your jewelry soak in warm soapy water for a few minutes.
-
Brush your jewelry to remove trapped dirt or grime.
-
Don’t forget to scrub the underside of your stone gently.
-
Rinse and clean with warm water.
-
Pat dry with a soft cloth.
-
Use a jewelry polishing cloth for the best results.
-
Inspect your jewelry regularly to address any signs of damage or lost stones.
-
If you feel uncomfortable cleaning, send us your jewelry for a free professional cleaning.

Only in the past few years has it become technologically possible to produce gem-quality lab-grown diamonds of commercially significant size and weight. And today, the annual production of pure lab-grown diamonds is only a few thousand carats, whereas the total production of natural diamonds is around 120 million carats per annum.
The good news is that we are one of the leading producers of some of the best quality lab-grown diamonds in the market worldwide. What’s more? We believe in following the international standards when it comes to producing lab-grown diamonds. Which means that every time you purchase from ROCKRUSH, you are presented with the IGI certification that comes with your delivery.
The IGI & GIA Laboratory Grown Report provides the same information as the IGI Diamond Report, but the colour of the report is yellow. Additionally, the lab-grown diamond's girdle is laser inscribed with the report number as well as the word lab-grown to avoid any misrepresentation.
Whether it be natural or lab-grown, gemstones should always be accompanied by a certificate attesting to quality. Regardless of location or marketplace, an authentic IGI & GIA Laboratory Report is the common language of trust and confidence in the gemological world.
