Diamond Engagement Rings
With a plethora of diamond engagement ring style, shape and colour combinations, there’s a ring design sure to suit your style.
Diamond engagement rings
A diamond engagement ring is a classic symbol of love and commitment, made famous in the 1900s by the iconic De Beers campaign, “A diamond is forever”. A diamond is synonymous with the modern concept of an engagement ring, as it truly is a gemstone that lasts forever, a beautiful sentiment for a long lasting partnership.
Diamonds can come in all shapes and sizes, however there are always a few factors to consider when looking at any diamond, and that is the 4 Cs, cut, clarity, colour and carat weight. Whether it be a lip shaped marquise or a beautiful emerald cut, a diamond must have excellent symmetry and optimal colour!
Diamonds are the most popular gemstone that we sell, making up around 80% of our centre stone sales. We offer precious gemstones such as sapphires, emeralds, rubies and paraiba tourmalines which make beautiful, unique engagement rings- however nothing gives off a classic vibe quite like a round brilliant cut diamond!
A diamond can be set with any metal, whether it be platinum, white gold, rose gold or yellow gold! The pristine white colour of a diamond pairs beautifully with warmer or cooler shades. Thanks to refined cutting skills and modern technology, diamonds come in a multitude of shapes and fancy cuts. You can truly be creative when designing your own diamond engagement ring, as a centre diamond can be paired with coloured gemstones, or other fancy cut diamonds.
The science of diamonds
Formed deep beneath the earth’s surface and composed of one single element, carbon, diamonds are created under high pressure and temperature conditions in the earth’s mantle. Most of today’s mined diamonds come from a specific geological formation called a kimberlite pipe, which is a volcanic pipe formed in the earth’s mantle, by a deep source volcanic eruption.
Diamonds are formed deep in the earth’s mantle, around 100 miles down, in what we would call the ‘diamond stability zone’. Some are found much further down in the mantle’s transition zone, around 400 miles down. In the industry, we would call a diamond from here a ‘superdeep diamond’. These diamonds are very precious, as they are regarded as time capsules, they hold valuable information of our planet’s past. During a volcanic eruption, diamonds amongst other rock are ejected towards the earth’s surface to be unearthed by miners. The rough diamond is then cleaved, cut, and polished to its perfect state ready to be sold.
In the last century, a new method of harvesting diamonds was formed, which now is beginning to have a profound affect on the diamond industry. Lab-grown diamonds are growing to be more popular, due to the alternative method used in creating the diamonds. In a chamber, pure graphite carbon is put under immense pressure in a lab in extreme heat, which creates a synthetic diamond. The diamond shares the exact same qualities as it’s mined counterpart, but instead of being created in the earth’s mantle it is created in a lab.

The 4 Cs of diamond quality
Diamond quality is measured by four quality characteristics named the 4 Cs-cut, clarity, colour and carat weight. This grading system was created by the Gemological Institute of America (GIA) and was designed to regulate the classification of diamond quality.
Cut grades are given only to round diamonds and refers to the balance of proportions achieved by the diamond cutter, not the diamond’s shape, as is commonly mistaken.
Ranging from excellent to poor, a cut grade combines three types of reflections-brilliance, fire and scintillation. For the greatest brilliance and fire, we recommend (and typically only offer) ‘very good’ and ‘excellent’ cut grades for round diamonds, which essentially guarantees a sparkly appearance.
Over 92% of our customers choose an excellent cut grade round diamond.
While they’re forming in the earth, diamonds develop natural birthmarks – slight irregularities and features that are visible to a skilled grader under 10x magnification. These are often referred to as ‘clarity characteristics’ and may or may not be visible to the naked eye depending on size, quantity, placement or colour.
To ensure the brilliance and fire that makes diamonds so enchanting, we offer ‘SI1″ clarity grades and above. In fact, each diamond is inspected to ensure that any clarity characteristics shouldn’t be visible to the naked eye.
The most frequently selected clarity grade is VS1 (very slightly included), closely followed by VVS2 (very very slightly included), VS2 (very slightly included) and VVS1(very very slightly included). Each of these clarity grades are excellent choices that are eye clean, meaning they won’t have inclusions visible to the naked eye. An ‘internally flawless’ (FL) diamond is very rare, less than 1% of all diamonds are graded as internally flawless.
A diamond’s colour usually refers to the level of colour in a white diamond. This grading system was invented to evaluate the amount of colour, or yellow tint, that is in a diamond. Diamond colour can also refer to different fancy colours, such as pink, blue or yellow diamonds. However, since fancy colours are quite rare, the white diamond has its own colour grading system. The white diamond is graded from D (colourless) to Z (light yellow).
The most popular diamond colour is F, closely followed by E and G. E and F colours are in the colourless category while G is in the near colourless category – all diamonds in the colourless and near colourless category would appear bright and white in appearance.
Carat is often confused with the size of a diamond, but it is actually a unit that measures weight. Today, one carat is equal to 0.2 grams. Larger diamonds are more rare, and more heavy, which increases their price. Though price increases aren’t steady, they exponentially increase with carat weight. For example, a 1ct diamond would be valued higher than two 0.50ct diamonds of the same quality. In general, a diamond of double the weight can cost three to four times more.
Just because a diamond is bigger, doesn’t mean it’s better. The right diamond isn’t just based on one factor but a combination of all 4 Cs (cut, clarity, colour and carat weight). When choosing a diamond, focus on the quality that’s most important to you, then work to balance the remaining three for the perfect diamond engagement ring.
