The Chupi Engagement GuideThe difference between lab-grown & mined diamonds
We make no secret of our love for lab-grown diamonds. Here’s why you should
consider one for your engagement ring.

From concerns surrounding ethics to the current financial climate, it’s easy to see why
those looking to get engaged are increasingly turning to lab-grown diamonds for their
forever ring. Before you consider doing the same, you might be wondering what the
difference is between a classic and lab-grown diamond.
The short answer is: there is none. Even to an expert eye, lab diamonds and natural diamonds
are virtually indistinguishable. In fact, a lab diamond will pass any diamond tester it comes
across. Where the two differ is their cost, how they are formed, and their impact on the world
on an environmental and humanitarian level.
To learn more about lab-grown diamonds vs. natural diamonds—including their cost—read on.
What are lab-grown diamonds?
Lab-grown diamonds, as their name suggests, are created in a lab rather than through nature's
resources. A common misconception is that lab diamonds are ‘simulated’, ‘fake’ or made of
different chemical compositions than a traditional diamond. Not so. They are chemically and
molecularly identical to classic diamonds, and just as beautiful.
How are lab-grown diamonds made?
To create a lab diamond, a thin slice of diamond (also known as a diamond seed) is placed into
a sealed chamber. Tremendous heat and pressure is applied to the diamond slice, mimicking the
conditions that form natural diamonds within the earth’s crust. From there, a rough lab-grown
diamond is formed, which is then hand-cut and polished.
What is the difference between a classic and lab-grown diamond?
Classic, natural or mined diamonds are formed deep within the earth over millions of years,
created through that same combination of heat and intense pressure. Then, they are extracted
from the ground through mining operations. The appeal of a classic diamond is their rarity,
as diamonds formed in the earth are finite. While this makes lab-grown stones less ‘rare’,
they are still identical. They are still both made of pure carbon – and held to the same

The process of creating a lab-grown diamond is more efficient and cost effective than the
process of diamond mining, therefore lab-grown diamonds themselves are more affordable. In
fact, a lab-grown stone is likely to be around 30% cheaper than a mined diamond, meaning that
you don’t have to sacrifice on carat, colour or clarity for your engagement ring.
For the ethically conscious, a lab-grown diamond will also be the more appealing choice. While
efforts are being made to improve the diamond mining industry, in terms of environmental and
humanitarian impact, the best way to ensure that your ring is conflict-free is by choosing a

Why buy a Chupi lab-grown diamond engagement ring?
At Chupi, every diamond we source – lab-grown or classic – is done so consciously. Where some
jewellery designers use low-grade lab-grown diamonds in their pieces, our beautiful labs are
held to the same meticulous international standards that our classic gems are measured by. Our
lab diamonds also have the added virtue of being carbon-neutral, where others grow theirs in
dirty coal-fueled plants.
