When it comes to buying diamonds, whether for an engagement ring or another special occasion, it’s important to understand the different types available. With so many options out there, it can feel a bit overwhelming, but don’t worry - we’ve got you covered! 
By the end of this article, you’ll be clued up on the different types of diamonds to help you find one that suits your style, budget and jewellery desires.

 
Type 1: Natural Diamonds
The most traditional and widely recognised type of diamond is the natural diamond. These diamonds are formed deep within the Earth’s mantle under extreme pressure and heat over millions of years. Natural diamonds come in a variety of shapes, sizes, and colours, and each one is truly unique due to its natural origin.
Natural diamonds are commonly used in engagement rings and fine jewellery. Because they have been around for millions of years, they carry a sense of timelessness and rarity. However, they can also be on the pricier side due to their limited supply and the cost involved in mining them.

Type 2: Lab-Grown Diamonds
Lab-grown diamonds, also known as man-made or synthetic diamonds, are real diamonds, but they are created in a laboratory rather than from the Earth. They have the same physical and chemical properties as natural diamonds, which means they are just as hard and sparkle just as brightly.
The difference between lab-grown and natural diamonds is that lab-grown diamonds are made in a controlled environment, using advanced technology to simulate the natural conditions that form diamonds. 
The process can take anywhere from a few weeks to a few months, making lab-grown diamonds a more affordable option. They are also considered a more ethical choice, as they don't come from mining, which can sometimes have a negative environmental impact.

Type 3: White Diamonds
White diamonds are the most popular and traditional choice for engagement rings and fine jewellery due to their clear, colourless appearance that allows light to reflect off the facets, creating a beautiful sparkle. 
Diamond colours are graded on the GIA scale, which ranges from D (colourless) to Z (light yellow or brown). The closer a diamond is to D, the higher its quality and price.
When shopping for a white diamond, you’ll want to consider the 4 Cs: cut, colour, clarity, and carat weight - You can learn more about what diamond carats are here. 

Type 4: Rose and Yellow Diamonds
For those who want something a bit more unique, rose and yellow diamonds provide a stylish twist on the traditional white diamond. Rose diamonds, with their warm pinkish hue, are a rare and romantic choice that has gained popularity in recent years. They get their colour from trace elements like nitrogen or radiation, which creates their distinctive tone.
Yellow diamonds, on the other hand, get their vibrant yellow hue from the presence of nitrogen, which gives them their warm, golden tones. These diamonds are often more affordable than pink or blue diamonds, making them an attractive option for those looking for a coloured stone without breaking the bank.

Type 5: Cushion Cut Diamonds
A cushion cut diamond is a beautiful blend of a round and square shape, with rounded corners that resemble a pillow (hence the name). This cut has been around for centuries and remains a popular choice for engagement rings. Cushion-cut diamonds can come in both white and coloured varieties, and their large facets allow for an impressive amount of brilliance and sparkle.
Cushion cut diamonds are also available in a variety of styles, such as the modified cushion, which has extra facets for enhanced brilliance, or the antique cushion, which offers a more vintage-inspired look. The cushion cut is often seen as a romantic and elegant option, making it perfect for those who want a diamond with a bit of character.

Type 6: Heart-Shaped Diamonds
For something truly unique and symbolic, heart-shaped diamonds are a stunning option. These diamonds are exactly what they sound like: diamonds in the shape of a heart to represent love and romance. Heart-shaped diamonds are often used in engagement rings or special occasion jewellery and carry a deeply meaningful sentiment.
Because the heart shape is quite complex, it requires careful craftsmanship to create the perfect shape, so it’s important to ensure you’re buying from a trusted jeweller. The heart-shaped diamond offers a distinctive and personal touch, making it a perfect choice for expressing love.

Type 7: Princess Cut Diamonds
Princess-cut diamonds are one of the most popular diamond shapes, especially for engagement rings. They feature a square or rectangular shape with sharp, uncut corners, giving them a modern and sleek appearance. Known for their brilliant sparkle, princess-cut diamonds tend to offer more bang for your buck because they tend to look larger than round diamonds of the same carat weight.
If you’re looking for something that feels both modern and classic, the princess cut is a fantastic option. It’s versatile, timeless, and available in a wide range of sizes and settings.

 
So, Which Diamond is Most Popular for Wedding Rings?
Because they are classic, sophisticated, and dazzle like no other, white diamonds are usually the most popular option for wedding rings. Due to their traditional appeal and versatility, round and princess cuts are particularly well-liked.
