In the shimmering world of gemstones, diamonds stand unmatched. Yet, with terms like 'lab-grown', 'man-made', and 'natural', the lines often blur. Let's dive deep and differentiate these sparkling stones.
What are natural diamonds?
Natural diamonds, frequently termed as mined diamonds, are Earth’s treasures formed billions of years ago. Comprising solely transparent carbon, their formation process is a tale of immense pressure and heat deep within the Earth's mantle. It's these conditions that drive them upwards, leading to deposits known as 'kimberlites'. Locating and mining these gems is a rigorous process, often spanning decades.
What are lab-grown diamonds?
Lab-grown diamonds represent human innovation. Mirroring the structural and aesthetic qualities of natural diamonds, they offer an ethical, sustainable, and often more cost-efficient choice, typically being priced 30-60% lower than their natural counterparts.
How are lab-grown diamonds made?
There are two separate ways to grow a diamond:
- HPHT (High Pressure-High Temperature): Here, a diamond seed is immersed in carbon. With the application of intense pressure and heat, the carbon undergoes crystallisation, forming a diamond.
- CVD (Chemical Vapour Deposition): A contemporary approach where a diamond seed is exposed to a chamber rich in carbon gas, leading to diamond formation.
Both techniques are designed to recreate the natural formation conditions of diamonds.
Can you tell the difference between lab & natural diamonds?
To an untrained eye, differentiating between lab-grown and natural diamonds is an intricate task. It's only under specialised equipment that one can truly discern their origins, often through laser inscriptions or inherent characteristics. Regardless of their source, both types of diamonds are graded by universal standards, with the 4Cs – cut, clarity, colour, and carat – being paramount.
Should I buy a lab or natural diamond?
The choice between lab-grown and natural diamonds rests with individual preferences. Whether it's the historical allure of a natural diamond or the modern, ethical appeal of a lab-grown gem, the decision is personal. For those seeking further guidance, we're here to assist.
