Understanding Lab Grown Diamonds
Before diving into the selection process, it is essential to understand what lab grown diamonds are and how they differ from natural diamonds. Lab grown diamonds are formed using two main techniques: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD).
- High Pressure High Temperature (HPHT): This method replicates the natural diamond formation process by mimicking the high-pressure, high-temperature conditions found deep within the Earth. HPHT diamonds often exhibit unique colours due to the minerals present during their formation.
- Chemical Vapour Deposition (CVD): CVD diamonds are created by introducing carbon-rich gases into a chamber, where they are ionised to form a plasma. This process allows for the controlled growth of diamond crystals over time.
Understanding these methods will not only give you insight into the quality of the diamonds but also help you appreciate the craftsmanship behind them.

Factors to Keep in Mind When Selecting a Lab Grown Diamond
When selecting the perfect lab grown diamond for your jewellery, several critical factors come into play:
1. The Four Cs: Cut, Color, Clarity, and Carat
- Cut: The cut of a diamond greatly affects its brilliance and overall look. A well-cut diamond reflects light beautifully, creating a stunning sparkle. Common cuts include round, princess, emerald, and oval. Choose a cut that suits your style and complements the design of your jewellery.
- Colour: Lab grown diamonds are available in a range of colours, from colourless to various shades of yellow, brown, and even fancy colours like pink and blue. Typically, the more colourless a diamond is, the greater its value. However, coloured diamonds can also be incredibly beautiful and unique.
- Clarity: Clarity refers to the presence of inclusions or blemishes within a diamond. Lab grown diamonds can be created with fewer impurities than natural diamonds, making it easier to find diamonds with higher clarity grades. Aim for diamonds with clarity grades of VS1 or higher for optimal brilliance.
- Carat: Carat weight measures a diamond’s size, and it is often one of the most crucial factors for buyers. While larger diamonds are typically more expensive, consider the overall appearance and how the diamond will fit within your jewellery piece rather than solely focusing on carat weight.
2. Certification
When you decide to buy lab grown diamonds, ensure that they come with a reputable grading certificate. Certificates from organisations such as the Gemological Institute of America (GIA) or International Gemological Institute (IGI) provide an unbiased assessment of the diamond’s characteristics and ensure authenticity. A certified diamond gives you peace of mind, knowing that you are purchasing a quality product.
3. Ethical Considerations
One of the most significant advantages of lab grown diamonds is their ethical sourcing. Unlike natural diamonds, which may be associated with unethical mining practices, lab grown diamonds are produced in controlled environments, ensuring no harm comes to people or the planet. When selecting your diamond, consider brands that emphasise ethical practices and sustainability in their production process.
4. Setting and Design
The design of your jewellery piece from your diamond jewellers plays a crucial role in showcasing your lab grown diamond. Consider whether you want a classic solitaire setting or a more elaborate design featuring side stones or intricate metalwork. Popular metal options for settings include platinum, white gold, yellow gold, and rose gold. The choice of metal can greatly enhance the appearance of the diamond and influence the overall style of the piece.
