How Many Carats Should a Diamond Pendant Be?

How Many Carats Should a Diamond Pendant Be? 

Bringing home the diamond pendant of your dreams is an exciting experience. A diamond pendant is a timeless piece of jewellery and a glamorous addition to any collection, but when you actually decide to pick a diamond pendant, things can get a little tricky. First, they come in various shapes such as oval, pear, and  circle diamond pendants. Once you’ve decided on shape, there are many other aspects to consider, including carat.

Overall, there are four objective measurements that will help you choose a diamond—carat, cut, colour, and clarity—but carat is often the most discussed attribute. 

What is Carat? 

Carat is a measure of the weight of a diamond. It should not be confused as a measure of its size, as a one-carat diamond can vary in dimension. Unless you pay close attention to the measurements of your stone, you can end up paying for diamond weight you don’t see.

Importance of Carat

When picking out jewellery, one of the biggest concerns is what carat diamond to purchase. This requires balancing your budget, style, and expectations carefully. At Holloway Diamonds, we will try to help you navigate the process using the following information about different carat sizes for diamond pendants. 

0.05 to 0.10 Carats 

Very small diamonds at the base of the throat add a little sparkle and a lot of elegance to any outfit. This weight is ideal for those who prefer delicate jewellery. 

0.25 Carats

At 0.25 carats, a round diamond measures about four millimetres in diameter, a great size for a noticeable but modest pendant. This size could be an ideal option as a dress-up to dress-down piece for someone with a petite frame. 

0.5 Carats 

A half-carat diamond will be noticeable and perfect for both everyday wear and special occasions. A half carat round diamond, measuring about five millimetres in diameter, has plenty of sparkle. 

0.75 Carats

With a diameter of about 5.7 millimetres, a diamond of this size is sure to incite compliments. Although this weight of stone still works from dress-up to dress-down, a 0.75-carat diamond has a lot of sparkle and may be too much for certain outfits. 

One Carat 

For those that need an element of glamour, a one-carat diamond might be the ideal size. At about 6.5 millimetres across, this might be the upper limit of what you can pair with jeans and a t-shirt.

1.5 Carats and Larger 

At larger sizes, diamonds become very sparkly and can be too much for a casual outfit. Still, some enjoy the look of a 1.5-carat diamond pendant for formal events. 

Is Carat Everything? 

Definitely not! When it comes to buying the right diamond, carat is just one of many aspects to consider. The size and the final look of the diamond depends on several other factors such as its cut, shape, setting, colour, and clarity. Considering all these details can be a daunting task to the untrained eye, this is where we come in. At Holloway Diamonds, we can guide you through the process of choosing the right diamond pendant for you or your loved one.
