Diamond Guide

Diamonds through the Loupe

We talk Loupe Diamonds

Our infatuation with diamonds is no secret, and it's a love story that's as deep and brilliant as the gems themselves. What sets us apart is our curiosity, passion, and attention to the finest details.

Under the expert eye of Chloe, our Loupe Diamond Buyer and GIA Graduate Gemologist, each diamond in the Loupe collections is carefully chosen by hand and eye for its allure beyond certification. Delve deeper into what makes a Loupe diamond so special, along with lots of inspiration to curate your own diamond collection.


Uncover Fire, Brilliance, and Scintillation

Each diamond in our collections is carefully chosen by eye, and we focus on the perfect balance of three essential components: fire, brilliance, and scintillation. This balance is what truly sets our diamonds alight, just like a firework, they’re nothing less than uniquely captivating.

Scintillation

Scintillation is the play of light interacting with the diamond's facets, creating flashes of brightness and darkness most visible when in motion.

Brilliance

Diamond brilliance is the amount of light that is reflected back from a diamond and is affected by its cut, clarity, and colour, as well as the quality of its polish and symmetry.

Fire

Just like the world’s most intense firework, the fire of a diamond is the colourful flashes of light that the stone diffuses whilst under the light.


Decoding the Four Cs

The 4 Cs of a diamond – cut, colour, clarity, and carat – are the key factors that determine its beauty. While our eyes play a significant role in choosing a diamond, Loupe diamonds promise quality with a minimum grade of SI1 or higher and each diamond comes with a certificate detailing its specific qualities, personally signed by Chloe.

Cut

The most important C of them all is cut, as it’s the symmetry, proportions and accuracy of the cut that determines the diamond's fire, brilliance, and scintillation. A well cut diamond can only be seen by eye and that’s why every stone is hand-chosen. We look for the perfect arrangement of facets and light, ensuring that only the most radiant and fiery diamonds make the cut for Loupe.

Colour

Diamonds are graded from ‘D’ (colourless) to ‘Z’ (tinted) by the Gemological Institute of America (GIA), and that’s why we only select exceptional diamonds falling within the colourless range (D-G). This means that when you own a Loupe diamond, it will be completely devoid of any visible colour, radiating a bright white brilliance.

Clarity

Diamond clarity, much like a fingerprint, is determined by the presence of internal characteristics known as inclusions and external characteristics called blemishes, which are formed deep within the earth under immense heat and pressure. All Loupe diamonds are SI1 or above (meaning there are no visible inclusions to the naked eye). This rigorous standard means only the finest make the final cut, and our selection process goes far beyond mere certifications.

Carat

When it comes to measuring a diamond's size, it’s all about the weight, not the size (one carat equals 0.20 grams). At Loupe, we provide diamond carats of up to 2ct. It’s certainly an influencing factor on the value, of course, but it’s the combination of all the 4 Cs that’s important and that’s why we search for perfectly formed diamonds, every time.


Beyond the Four Cs

Our other Cs give you what we like to call ‘the Loupe seal of approval’: Confidence, Certification, and Care. We look outside the 4 Cs when we select our diamonds and that’s why each and every piece in our collections is completely unique.

Confidence

Investing in diamonds needs to be done with utter confidence. That's why we select diamonds with exceptional life and scintillation, and we buy as if we’re buying for ourselves. Look for the Loupe logo engraved on every piece. Read more on our hallmarking process here.

Certification

A Loupe diamond is so special because each one is hand-selected to meet the highest standards of quality. That’s why every diamond ring and piece of diamond jewellery comes with a certificate signed by Chloe, giving you her personal seal of approval.

Care (for a lifetime)

Aftercare isn't just an afterthought at Loupe, and we want to make sure your Loupe diamond keeps its undeniable sparkling power. That’s why we offer a lifetime of care in our boutiques and online. Read more and we’ll let you in on all the secrets to a lifetime of scintillation.


Diamond cuts and shapes

While the two terms are commonly used interchangeably, it is important to recognise that true beauty and brilliance come from the diamond's cut, rather than its shape alone. Diamond shape refers to the stunning silhouette that catches your eye while the cut focuses on symmetry, proportions, and light play.

Cutting techniques

The three main cutting techniques for diamonds are the brilliant cut, step cut, and mixed cut. Brilliant cut diamonds have 57 or 58 facets that increase brilliance and light return, while step cut diamonds have long and narrow facets, perfect for emphasising colour and clarity, with the most popular being the emerald cut. Mixed cut diamonds combine both step and brilliant facets, seen in newer diamond shapes such as princess, cushion, and radiant cut diamonds.

We believe that when it comes to choosing your diamond shape you’ll just know when you’ve found the one. Loupe diamond shapes include round brilliant, oval, princess, pear, emerald, cushion, baguette, and more. For an extra helping hand choosing the perfect diamond shape for you, you can book a bespoke consultation with a Loupe diamond expert at one of our boutiques.
