Just how can you measure their quality - and why is this so important?

Here’s the headline: we’re all looking for sustainable luxury. And we get it - which is why lab-grown diamonds stand out as a beacon of progress and innovation.

These gems, crafted with precision and care, genuinely embody the timeless allure of diamonds, and also reflect a commitment to ethical and environmentally friendly practices. But how much do you actually know about the world of lab-grown diamonds? Understanding their creation, the importance of certification, and the exceptional value they offer to those who cherish both beauty and responsibility is key - so we’re here today to lend a hand!

A quick intro to lab-grown diamonds

First off: Are lab-grown diamonds real diamonds? YES! They’ve the same chemical, physical, and optical properties as those mined from the earth. The technology behind their creation, whether it be High-Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD), mirrors the natural processes that form diamonds deep within the Earth, but without the extensive mining operations.

Choosing a lab-grown diamond means opting for a stone that is indistinguishable from its mined counterpart, even to the trained eye. The only difference lies in their origin stories, one from the bowels of the earth and the other from the pinnacle of human ingenuity. This choice does not compromise on quality, beauty, or value; rather, it enhances the purchasing decision with layers of ethical consideration and affordability.

The role of certification

Certification plays a pivotal role in the world of lab-grown diamonds, ensuring that each gem meets stringent standards of quality and authenticity. Similar to mined diamonds, lab-grown varieties are assessed based on the four Cs—colour, cut, clarity, and carat weight. This process, conducted by renowned certification bodies like the International Gemological Institute (IGI), provides peace of mind and confidence in the diamond's characteristics and origins - and even more so when you opt for a bespoke design service.

A certificate for a lab-grown diamond offers a transparent account of the gem's properties, ensuring that it has been scrutinised and graded with the utmost precision. This transparency is key in making an informed choice, allowing one to appreciate the beauty and quality of the diamond, secure in the knowledge of its ethical and sustainable origins.

These gems are perfect for those who seek the lustre and depth of diamonds, with the added assurance of ethical sourcing and environmental consciousness - like the negative impacts of traditional diamond and gold mining.

Value for the modern consumer - how does it line up?

Lab-grown diamonds represent both a strong choice and a statement of declaration of love for the planet and its future.

These diamonds offer the same breathtaking beauty and durability as mined diamonds but at a fraction of the cost. The process of creating a lab-grown diamond is more efficient and less resource-intensive, resulting in savings that are passed on to the consumer. This makes lab-grown diamonds an attractive option for those seeking to maximise their investment without compromising on quality or ethical standards.

So there you have it: choosing a lab-grown diamond does not mean settling for less. Instead, with top picks from the online shop here at Infinity Diamond Jewellery, it’s as close to ‘the best of both worlds’ as you’re likely to get.
