A natural diamond is made from carbon and grows deep within the earth’s mantle under high pressure and temperature conditions.

Once a diamond has formed it travels to the earth’s surface where it’s mined and begins its journey to be refined, cut and polished ready to be set into jewellery.

All of the natural diamonds listed are GIA graded, certified, and have come from suppliers who’ve met our stringent ethical and sustainability standards.

Lab-grown diamonds are diamonds that have been grown in a laboratory.

Lab-grown diamonds share the exact same structure and properties as any other natural diamond. Physically, they’re no different to natural diamonds and because of that we shouldn’t confuse a lab diamond with a ‘diamond simulant’ such as moissanite or cubic zirconia. A lab grown diamond also shouldn’t be classified as a synthetic diamond, as these stunning gemstones are the real deal.

All of the lab grown diamonds listed here have been certified by the International Gemological Institute and come from manufacturers who’ve met our stringent ethical and sustainability standards.

Coloured gemstones like sapphires are the perfect choice for those hoping for a pop of colour in their ring.

Often considered a blue stone, sapphires actually come in a wide array of glorious colours from yellow and pink to teal, peach, purple, green and even red, which is in fact, a ruby.

Each colour variation of these gemstones are suitable for everyday wear and they all have sentimental symbolisms.

Every one of our sapphires are hand selected to ensure quality as well as symmetry, clarity, polish and uniformity in colour and light reflection, while retaining their unique charm.

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.

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.

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 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 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.

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.

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.

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.

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.

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

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 further conflicts from being financed by the diamond trade. They launched the Kimberley Process Certification Scheme in 2003, made up of over 80 participating countries and at the time, reduced the trade in conflict diamonds to less than 1% of all natural diamonds.

The Kimberley Process was the first step towards greater transparency in the industry, but in our opinion, didn’t do enough. Today we go the extra mile by actively excluding diamonds from certain origins (currently Angola, Zimbabwe and Russia) while also providing customers diamond provenance information when available.

You can access this information by contacting us for a specific diamond or via our “country of origin” search filter, which shows only diamonds where the country of origin is known.

As with all natural materials, it’s near impossible to achieve a perfectly cut gemstone because often, their very slight imperfections are part of their charm and character. We inspect every one of our coloured gemstones to ensure the levels of symmetry and presence of windows in the stone are at range we believe presents the stone in its best way.

While often confused with the size, carat weight is actually a unit that measures a diamond or gemstone’s weight. When choosing a gemstone, you should consider all of the quality characteristics to find a beautiful balance.

Unlike diamonds, the colour grade of coloured gemstones is determined based on the tone of the colour present in the stone. For example, a more subtle and less saturated tone would sit on the lighter end of the scale, while a more vivid and highly saturated gemstone would sit on the darker end of the scale. This is why each gemstone is assigned a colour grade to reflect the relative lightness or darkness of the colour and will be graded as ‘light’, ‘medium’, ‘medium dark’ or ‘dark’.

It’s also important to remember that the charm of coloured gemstones is that they’re entirely unique. As a natural product, they’ll have their own characteristics and colours that appear differently on screen and in different angles.

When gemstones are formed deep in the earth, they develop natural birthmarks. These slight irregularities are known as ‘clarity characteristics’ or ‘inclusions’. These may or may not be visible to the naked eye depending on their size, quantity or placement which makes an entirely flawless gemstone so rare. In fact, less than 1% of natural gemstones have zero ‘clarity characteristics’.

We determine a gemstone’s clarity depending on whether the stone is ‘eye-clean’ to the naked eye. If the ‘clarity characteristics’ or ‘inclusions’ are 100% invisible to the naked eye from the top of the stone, we believe it’s a suitable gemstone.

We hand pick all our gemstones to ensure they’re of the highest quality, guaranteed. Your gemstone has been reviewed and examined by our team according to our quality control standards, ensuring it has a fantastic cut, no structural compromises, and a consistent colour.
