The 4 C's



The colour of a diamond ranges from colourless to yellow, and sometimes even pink or blue. The less colour a diamond has, the more valuable it is.
Diamond colour is graded on a scale from D (colourless) to Z (yellow). 

Diamonds with a colour grade of D to F are considered colourless and the most valuable. Diamonds with a colour grade of G to J are near colourless and still appear white to the naked eye. Diamonds with a colour grade of K or lower have a yellow tint and are less valuable. 

The colour of a diamond can affect its price, but it's important to remember that personal preference plays a significant role in choosing a diamond's colour. Some people prefer a warmer diamond with a yellow tint, while others prefer a cool, colourless diamond.



The carat weight of a diamond refers to its size. The larger the diamond, the more it will weigh and the more it will cost.

Diamonds are weighed in carats, and one carat is equal to 0.2 grams. Most engagement rings feature a diamond between 0.5 and 1.5 carats, but the size of the diamond ultimately depends on your budget and preferences.

When choosing a diamond, it's important to consider all of these factors in combination. You may choose a smaller diamond with higher clarity and colour grades, or a larger diamond with a lower grade in one of these areas. The choice ultimately depends on your preferences and budget.



Diamonds can be cut in different shapes, including round, princess, cushion, emerald, and oval, to name a few. Each shape has its own unique character and appeal. Round diamonds are the most popular, followed by princess-cut diamonds, which are square-shaped with pointed corners.

When selecting a diamond, look for one with an excellent or very good cut grade. This means that the diamond has been cut to maximize its brilliance and fire, and it will reflect light beautifully.



Diamond clarity is graded on a scale from flawless to included. A flawless diamond has no inclusions or blemishes visible to the naked eye, while an included diamond has numerous visible inclusions.

Most diamonds have some degree of inclusion, but a diamond with a clarity grade of SI1 or better will appear clean to the naked eye. Diamonds with a higher clarity grade will be more valuable but can be difficult to distinguish from diamonds with a slightly lower grade.

The Specifics



When it comes to engagement rings, the metal used is just as important as the diamond. The most popular metals for engagement rings include platinum, white gold, yellow gold, and rose gold.

Platinum is a popular choice for its durability and hypoallergenic properties. White gold, made by mixing pure gold with other metals, is a popular alternative to platinum and is often more affordable.

Yellow gold and rose gold are classic choices, with yellow gold being the most traditional and rose gold having a more unique, romantic feel. The choice of metal ultimately comes down to personal preference, as each metal has its own unique properties and style.



Engagement rings come in a variety of styles, each with its own unique look and feel. Some popular styles include solitaire, halo, three-stone, vintage, and modern. Solitaire rings feature a single diamond or gemstone, making them a timeless and classic choice.

Halo rings have a central stone surrounded by a ring of smaller diamonds or gemstones, adding extra sparkle and brilliance. Three-stone rings symbolize the past, present, and future of a relationship, with each stone representing a different time.

Vintage rings feature intricate details and designs inspired by earlier eras, while modern rings have sleek, clean lines and a contemporary look. The style of engagement ring you choose should reflect your personal taste and style, as well as your partner's preferences.
