THE COMPLETE GUIDE TO
Lab-Grown Diamonds
Curious about lab-grown diamonds and whether they’re the right fit for your next piece of fine jewellery? Our guide covers everything you need to know, helping you make an informed choice with confidence and clarity.
What Are Lab-Grown Diamonds?
Lab diamonds are genuine diamonds, created in a controlled environment using cutting-edge technology to replicate the high-pressure, high-temperature conditions of the Earth’s crust. Chemically, physically, and optically identical to mined diamonds, they deliver the same brilliance and durability. Lab diamonds are sustainable, reducing the environmental and ethical concerns associated with traditional diamond mining.
How Lab Diamonds Are Made?
There are two primary methods used to create lab-grown diamonds: High-Pressure High-Temperature and Chemical Vapor Deposition.
HPHT involves exposing carbon to intense heat and pressure, mimicking natural diamond formation. CVD, a newer method, involves placing a carbon-rich gas mixture in a chamber with a small diamond seed, where it gradually crystallises layer by layer.
Both techniques result in high-quality diamonds, allowing for precision in crafting stones with desired characteristics.
Lab vs. Natural Diamonds: Key Differences
While lab and mined diamonds look identical, they differ in origin and environmental impact. Lab diamonds provide: Affordability: Typically 30-40% less than mined diamonds of similar quality. Environmental Responsibility: Controlled production results in a smaller carbon footprint. Conflict-Free Assurance: Lab diamonds are free from human rights and environmental issues sometimes tied to mining. These benefits make lab diamonds a sustainable choice without compromising on quality or beauty.
Why Choose Lab-Grown Diamonds?
Lab-grown diamonds are more than just a sustainable choice; they’re a statement of values. Here’s why they’re a growing favourite for engagement rings and bespoke jewellery

HOW TO CHOOSE A DIAMOND
THE FOUR C'S
When it comes to diamonds, there are four defining factors that determine its quality: Cut, Colour, Clarity and Carat. These characteristics will directly impact the lustre, sparkle and overall look of your diamond. We preselect our stones to offer you only the highest colour (DEF) and clarity (VS+) available.
CUT
A diamond’s cut refers to the balance of proportion, polish and symmetry to maximise the stone’s light performance. This is arguably the most important of the four C's, as the cut has the most significant effect on the diamonds appearance and sparkle.
COLOUR
This refers to the natural colour or lack of colour visible within a diamond, not the coloured flashes of light the diamond emits when it moves, known as fire. Diamond Colour is graded alphabetically from D (Colourless) to Z (Light Yellow). At EF Studios we work with D-F coloured laboratory diamonds, ensuring the brightest and best quality stones.
CLARITY
Clarity refers to how clear a diamond is, grading its purity according to the number of imperfections or inclusions present within the stone. Our EF Studios diamonds range between the VVS1-VS1. We strive to only work with the most exquisite diamonds that deliver on our commitment of balancing quality and affordability.
CARAT
Carat (ct.) refers to the specialised unit of measurement used to weigh a diamond and other gemstones. We have pre-selected 1ct, 1.5ct and 2ct diamonds for our engagement ring designs. You can customise our rings with different diamond shapes and carat weights.
