About Our Diamonds
The diamonds you will find in this diamond search can be purchased loose, or set into an engagement ring or jewellery piece.
All the diamonds listed here are GIA graded, certified and ethically sourced. Images, videos and sourcing location are available for most diamonds, upon request.
When shopping for a diamond through our diamond search, we suggest you first consider the diamond shape and your price point. The shapes available on our diamond search include round brilliant, cushion, oval, emerald, pear, princess or square, marquise, asscher, radiant, heart and hexagonal. However, we can source a whole host of different diamond shapes and cuts from antique cuts, like rose cut or the Old European to fully custom-cut shapes.
Once you have a shape in mind, we suggest you optimise for the diamond carat weight and its brilliance (measured by the diamond’s proportions and cut grade) and only then colour and clarity.
Other characteristics, including the diamond’s polish, symmetry, fluorescence, depth and table are important too, and your diamond consultant can advise on these characteristics (or you can read more about these here).
The diamonds listed in our search tool are checked in person by our buyers to confirm they are eye-clean – their natural inclusions are not easily visible to the naked-eye. We then check for their brilliance and lustre, as we believe all our diamonds should have the maximum possible fire and sparkle.
This means that the diamonds listed here are checked again in person once you place your order. Once checked we e-mail you to confirm that the diamond you selected is beautiful and that we are proceeding with your order as planned.

Carat weight explained
While often confused with the size, carat weight is actually a unit that measures a diamond’s weight. When choosing a diamond, you should consider all 4 Cs to find a beautiful balance.
Cut explained
Applicable to round diamonds only, a cut grade refers to the balance of proportion, symmetry and polish achieved by the diamond cutter. Cut has the greatest influence over a diamond’s overall brilliance, with excellent and very good cut diamonds having the highest light return.

Clarity explained
When diamonds are formed deep in the earth, they develop natural birthmarks. These slight irregularities are known as ‘clarity characteristics’. These may or may not be visible to the naked eye depending on their size, quantity or placement which is why it’s important to consider clarity when choosing your diamond.
Colour explained
White diamonds can have a colour grade from D (colourless) to Z (light yellow). Colour grades D-F are colourless and icy white and grades G-J are nearly colourless, with distinctions so subtle, most are indistinguishable to the untrained eye. We offer J colour grades and above.
Polish explained
Polish refers to the smoothness of the exterior of a diamond. We offer very good or excellent polish. This means that any marks that may appear on the diamond are difficult, or very difficult to locate under 10x magnification.
Symmetry explained
Symmetry refers to the angles to which the facets are aligned. We offer very good to excellent symmetry which means any symmetry defects are extremely difficult to see under 10x magnification or no defects are visible under 10x magnification.
Fluorescence explained
Natural diamonds will emit a fluorescent glow when exposed to ultraviolet light, but their appearance in natural light is not affected. Diamonds with none or a faint fluorescence are rarer than those with a strong or very strong fluorescence. We offer diamonds with none, faint, medium or strong fluorescence grades.
What is a GIA report?
The GIA (Gemological Institute of America) is the most widely recognised diamond and gemstone grading laboratory.
In 1953 the GIA developed its International Diamond Grading System and the Four Cs (cut, clarity, colour, and carat weight) as a standard to compare and evaluate the quality of diamonds.
The GIA’s grading standards are widely considered to be among the strictest in the industry and as a diamond buyer, you can be certain of a diamond’s quality appraisal if it comes with a GIA grading report.
What is an IGI report?
The International Gemological Institute (IGI) was established in 1975 and is the oldest laboratory in Antwerp today and the largest organisation of its kind, operating 18 laboratory locations around the world grading finished jewellery, natural diamonds, lab-grown diamonds and gemstones.
Back in 2005, the IGI was the first gemological institute to begin fully grading lab-grown diamonds and is now a world-leader. Having amassed more experience and expertise than any other organisation, IGI continues to instil confidence in lab-grown diamond grading for the entire industry – from manufacturers and retailers to consumers.
What is a GCAL report?
The Gem Certification & Assurance Lab is located in New York City and established the GCAL reporting process in 2001 to unify the diamond grading process in order to maintain accuracy and consistency.
GCAL is one of only three diamond grading labs in the world that is ISO 17025 Accredited and with every year, GCAL’s methods and procedures are independently audited to ensure upheld standards across their analysis and certification.
Country of origin
As part of our efforts towards greater transparency in the diamond industry, we are attempting to identify the exact country each diamond we list has come from.
By selecting this filter, you will be able to see in which country this diamond was discovered and mined.
When we identify diamonds that have come from countries where human rights violations persist to this day, we filter them out. While not all the diamonds we list have a country of origin listed, all have been traded with a Kimberley Process certificate. Read more about this on our ethical sourcing page here
What is The Kimberley Process?
Governments, charities, and the diamond industry united after the civil war in Sierra Leone to create the Kimberley Process (KP) in an attempt to prevent such a war from ever happening again. They launched the Kimberley Process Certification Scheme in 2003 with the goal of ending the trading of conflict diamonds.
The Kimberley Process is made up of 80 participating countries representing most of the nations involved in the diamond trade and it has successfully reduced the conflict trade to less than 1% in the global diamond industry.
