Top tips for selecting the best coloured lab grown diamonds

When you are looking for a coloured stone that is both stunning and sustainable, choosing a lab grown diamond is a decision that aligns with both your values and your style. Here is everything you need to know about selecting the best coloured lab grown diamond, from understanding colour to choosing the right shape.

Why choose coloured lab grown diamonds over mined stones?

Lab grown diamonds are not just an environmentally friendly choice, they also offer unmatched beauty and value.

Lower carbon emissions. Lab grown diamonds emit just 20 per cent of the carbon dioxide produced by mined diamonds.
Reduced water usage. Production uses up to seven times less water compared with traditional mining.
Minimal waste. A study by Frost and Sullivan found that mining generates 4,383 times more waste than lab grown production.
Sustainability. By choosing lab grown diamonds you contribute to a more sustainable and ethical jewellery industry.

The unique appeal of coloured lab grown diamonds

Coloured lab grown diamonds bring an exciting twist to the traditional market. They combine brilliance and quality with the ability to create stunning colours. Whether you are drawn to the warm glow of yellow, the soft elegance of pink, or the captivating hue of blue, coloured lab grown diamonds are a perfect way to showcase unique style.

Factors to consider when choosing

Choosing a coloured lab grown diamond is not just about picking a colour. Several important factors will help you find the right one.

Colour: understanding the 4Cs in coloured stones

Colour is the most important factor here. The 4Cs, cut, colour, clarity and carat, still apply, but with a focus on how vibrant and pure the colour is.

Hue. The hue refers to the type of colour that defines the stone's identity, such as pink, blue, yellow or green. It is the primary colour you see and often influences your first impression.
Tone. Tone is the lightness or darkness of the colour. A lighter tone gives a softer, more pastel look, while a darker tone gives a richer, more dramatic appearance.
Saturation. Saturation refers to the intensity or purity of the colour. A more saturated stone will have a richer, deeper colour and a more vibrant appearance.

Cut: the importance of proportions and symmetry

The cut plays a crucial role in how the colour is perceived. A well cut stone reflects light in a way that enhances its colour, making it appear even more vibrant. Pay attention to proportions, symmetry and polish to ensure the stone maximises its colour potential.

Clarity and carat

While clarity and carat weight are always important, with coloured stones the emphasis is often on colour intensity rather than perfect clarity. Minor inclusions will not diminish the beauty of a coloured lab grown diamond, especially when the colour is rich and vibrant. When it comes to carat weight, bigger does not always mean better. Sometimes a smaller, more intense colour makes a stronger statement.

Popular colours and shapes

Yellow, pink, blue and green

Coloured stones are not just visually striking, they are emotional triggers. Understanding what each hue represents can help you position your inventory more strategically.

Yellow. Bright and full of life, yellow stones convey energy, joy and optimism. Great for customers who want bold, vibrant pieces.
Pink. Soft yet luxurious, pink stones speak of romance, elegance and timeless beauty. A strong choice for bridal or high end collections.
Blue. Cool, rare and regal, blue stones exude calm, sophistication and exclusivity. Ideal for luxury buyers seeking something distinctive.
Green. Earthy and tranquil, green stones appeal to those drawn to nature, balance and uniqueness. Perfect for eco conscious or design forward shoppers.

By aligning colour psychology with customer intent, you can curate more targeted collections and enhance the emotional value of every purchase.

Ideal shapes

Shape influences how the colour is perceived, so selecting the right one is essential. Round and radiant cuts are the most popular choices for coloured stones, as they maximise light reflection and enhance colour intensity. Other shapes like oval, cushion and princess can also be stunning, depending on personal style and the design of the jewellery.

How to ensure quality

When you are investing in a coloured stone, quality is key. Make sure you are selecting one that has been certified and sourced from a trusted supplier to ensure both authenticity and ethical production.

Choosing certified stones

To ensure the highest quality, make sure your stone comes with a certification from a reputable gemological laboratory. A certification assesses colour, clarity and overall quality, giving you peace of mind that you are getting exactly what you paid for.
