Understanding Diamond Clarity, Colour, Carat, Cut & Certification
When choosing a diamond, several key factors determine its beauty and value:
- Clarity – Refers to the presence of natural inclusions within the diamond. The fewer inclusions, the higher the clarity, ensuring a more brilliant and flawless appearance.
- Colour – Diamonds range from completely colourless to shades of yellow or brown. The less colour present, the rarer and more valuable the stone.
- Carat – A diamond’s weight is measured in carats, with higher carat diamonds generally being larger. However, factors like cut and setting can enhance its visual impact beyond just weight.
- Cut – The cut determines how well a diamond reflects light, influencing its sparkle and brilliance. Popular cuts include Round, Princess, Oval, Emerald, and Pear, each offering a unique style and level of radiance.
- Certification – A certified diamond has been assessed by an independent gemological laboratory, such as GIA or IGI, ensuring its quality and authenticity. Certification provides peace of mind and guarantees you’re investing in a diamond of true value.

Choosing the right ring size is essential for comfort and wearability, and we’re here to make the process seamless. As standard, our rings are mainly crafted in Size M, which is the average UK ring size. However, we understand that everyone’s hands are unique, which is why we offer a free ring sizing service with all our orders over £1000.
Resizing Your Ring
Most of our rings can be adjusted to suit your size, ensuring a perfect fit. Simple bands and classic designs can be resized up or down with ease. However, for certain intricate designs—such as eternity rings with stones set all the way around, or detailed patterns—resizing may be more limited. In these cases, adjustments may only be possible one or two sizes up or down to preserve the integrity of the design.
Large Size Adjustments
If you require a significant size increase, additional materials may be needed to maintain the structure and beauty of your ring. In these cases, a small material fee will apply, but we will always discuss this with you beforehand to ensure transparency.
Need Help?
If you're unsure of your ring size, we’re happy to assist! Our team can provide guidance to ensure your new piece fits just right. Whether you need a minor tweak or a complete resizing, we’ll make sure your ring is as comfortable as it is beautiful.
Below we have added the UK, US and EU ring size guide so that you have a rough idea on what your ring size will be. Please note that fingers include a wide set knuckle and are prone to thermal expansion / contraction therefore it is best to see a professional.
