Blue Diamonds vs White Diamonds: What’s The Difference?

Anyone who has ever seen a diamond knows that it is special. It has an undeniable sparkle and brilliance that sets them apart from other gemstones.

When most people think of diamonds, they picture clear, sparkling stones. However, these gems actually come in all sorts of colours, including blue and white. While both types of diamonds are prized for their beauty, there are some key differences between them.


The most obvious difference is, of course, colour. Blue diamonds get their colour from trace amounts of boron atoms in the crystal structure. The amount of boron present determines how intense the blue colour is. Meanwhile, white diamonds are typically colourless due to the absence of any hue-inducing impurities.

A classic piece with a modern twist, the Star Carat Starlight Blue Diamond Ring is a stunning example of fine jewellery. With its intense blue colour, this ring is sure to become a treasured part of your personal collection.


Unlike other precious stones, which are found in abundance, diamonds are quite rare. In fact, only a handful of diamond mines exist in the world today, with many of these mines located in remote, difficult-to-reach areas. This is why extracting diamonds can be a time-consuming and expensive process. Blue diamonds are even rarer, with less than 0.1% of all diamonds mined being blue.

The Star Carat Fairy Blue Diamond Pendant is a perfect example of the beauty of these rare gemstones. The delicate setting enhances the diamond’s brilliance, making it shimmer and sparkle like a star in the night sky. With its timeless design and exquisite craftsmanship, it has a way of captivating the eye and eliciting feelings of wonder.


Both blue and white diamonds are graded using the Four Cs system: cut, clarity, colour, and carat weight. However, because blue diamonds are so rare and highly sought-after for their beauty, they often sell for a higher price per carat than white diamonds. With its timeless pavé design, the Star Carat Classic Pave Blue Diamond Ring is sure to dazzle. Wear it as an engagement ring, a promise ring, or simply a symbol of your affection—the choice is yours.


Though blue diamonds are amongst the rarest of all diamonds, they remain some of the most popular gems on the market. Part of their appeal lies in their unique colour—while blue diamonds can occur in a variety of shades, from pale sky blue to deep navy, they all share an undeniable brilliance.
