Blue diamonds are among the most captivating gemstones in the world of fine jewellery. Their cool, elegant colour and exceptional brilliance make them a favourite for those seeking something distinctive yet timeless. A blue diamond offers a refined alternative to traditional white diamonds while expressing confidence, individuality, and sophistication.
Whether you are choosing a meaningful milestone ring, a modern engagement ring, or your first coloured diamond, this Blue Diamond Guide will help you understand how blue diamonds are graded, what influences their beauty, and how to select the perfect one.
At Her Crown, our Aura Collection features IGI-certified lab-grown blue diamonds in carefully selected Fancy Intense and Fancy Vivid colour grades, handcrafted in elegant 14k or 18k gold settings.
What Is a Blue Diamond?
A blue diamond is a genuine diamond with a natural or laboratory-created blue body colour.
Unlike white diamonds, which are graded by the absence of colour, blue diamonds are admired for the richness, purity, and depth of their blue hue.
Lab-grown blue diamonds have the same:
- Chemical composition
- Crystal structure
- Hardness (10 on the Mohs scale)
- Brilliance
- Fire
The difference is simply how the diamond is created.

Are Lab-Grown Blue Diamonds Real?
Yes.
Lab-grown blue diamonds are real diamonds with the same optical, physical, and chemical properties as mined diamonds.
Using advanced technology, scientists recreate the natural diamond-growing process, producing genuine diamonds that can be independently graded and certified by respected laboratories such as IGI.
This allows buyers to enjoy exceptional beauty with confidence.

How Are Blue Diamonds Graded?
Blue diamonds are primarily evaluated by the quality and intensity of their colour.
Gemologists assess three important characteristics.
Hue
Hue refers to the primary blue colour of the diamond.
Some diamonds may display subtle secondary hues that create unique visual character.
Tone
Tone describes how light or dark the blue colour appears.
A balanced tone often creates the most elegant appearance.
Saturation
Saturation measures the richness and purity of the blue colour.
Greater saturation generally results in a more vivid and striking diamond.

Colour intensity is described using internationally recognised grading terms.
Fancy Blue
A refined and subtle blue with understated elegance.

A richer, more vibrant blue that creates an elegant yet eye-catching appearance.
This is one of the most popular choices for luxury jewellery.
Fancy Vivid Blue
The highest level of colour intensity for many blue diamonds.
These diamonds display exceptional richness, remarkable brilliance, and extraordinary visual impact.
What Does a Blue Diamond Symbolise?
Blue diamonds are often associated with:
- Wisdom
- Confidence
- Calmness
