WHAT ARE LAB GROWN DIAMONDS?

ADD LUXURY AND LUSTRE TO EVERY DAY
First created in 1954 by General Electric, lab-grown diamonds were initially proposed for industrial use, as they were low-grade and lacked aesthetic appeal. As time passed, remarkable technological advancements paved the way for gem-quality diamonds. These are rough-grown using HPHT (high-pressure, high-temperature) or CVD (chemical vapour deposition) methods.

FROM SEED TO TANGIBLE BRILLIANCE
In the HPHT method, a small natural diamond seed is subjected to extreme conditions in a controlled environment, replicating the earth’s diamond-forming process.

The CVD method grows diamonds from a carbon-rich gas, with an energy source triggering crystallisation.
The result of either method is rough stones cut to perfection by skilled diamond cutters, just like natural diamonds.

ARE LAB GROWN DIAMONDS REAL DIAMONDS?
Yes. Even an experienced jeweller can only distinguish between mined and lab-grown diamonds with specialised equipment. They are identical except in one respect – the price.

HOW TO CHOOSE YOUR COLOUR
Given the incredible value-for-money lab-grown diamonds represent, we have limited the colour range to only the highest quality, D to F.

When considering a white diamond, the colour grading system describes the degree of colourlessness. This starts at D (with the least colour) and goes to  Z, which is intense yellow.
Many of these diamond colour distinctions are so subtle that they are invisible to the untrained eye – the colour difference between D and E, for example. However, these distinctions will make a difference to the diamond’s price.

The only exception to this rule is for those looking for a yellow diamond, in which case we advise that you focus on colours from U to Z.

CHOOSING CLARITY

The Diamond Clarity Scale has six categories, some of which are divided, for a total of 11 specific grades. Keep in mind that grading is done under 10x magnification.

Given the incredible value-for-money lab-grown diamonds represent, there really is no point considering a stone lower than VS2, and you will not see these stones on our site. 

Diamonds are graded as one of the following:

  • Flawless (FL) No inclusions and no blemishes visible.

  • Internally Flawless (IF) No inclusions visible.

  • Very, Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification

  • Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification, but can be characterised as minor.

FLUORESCENCE

We will only show diamonds with Nil or faint fluorescence grades.
When exposed to strong UV light, diamonds may emit a soft glow, usually blue or sometimes yellow, known as fluorescence. We would rather show you diamonds with nil or faint fluorescence grades. The subtle nuances of this phenomenon add another layer of uniqueness to your diamond selection.

The overall appearance of the diamond is the most important, and of the ‘4 C’s’, CUT has the most impact.

We don’t settle for anything less than extraordinary, nor should you.
