Choosing the diamond first gives you complete flexibility when creating jewellery. You can compare shape, carat weight, measurements, color, clarity, proportions, certification, and price before selecting the ideal stone for an engagement ring, pendant, earrings, bracelet, or bespoke fine jewellery piece.
What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds created in controlled environments using advanced technology that recreates the conditions under which diamonds form naturally. They have the same physical, chemical, and optical properties as mined diamonds and offer the same brilliance, fire, hardness, and durability.
Lab grown diamonds are generally created using one of two methods: CVD, or Chemical Vapor Deposition, and HPHT, or High Pressure High Temperature. Both processes produce genuine diamonds that can be independently graded and certified using the same quality standards applied to natural diamonds.
The primary difference between lab grown and natural diamonds is their origin. Natural diamonds form beneath the earth over billions of years, while lab grown diamonds are created in carefully controlled environments. The finished result is a genuine diamond with exceptional beauty and performance.

How to Choose the Best Lab Grown Diamond
When selecting a lab grown diamond, evaluate the 4Cs: cut, color, clarity, and carat weight. These characteristics work together to determine the diamond's appearance, proportions, brilliance, and overall value.
Prioritise Cut Quality
Cut quality has the greatest influence on a diamond's sparkle and light performance. A well-cut diamond reflects light more effectively and can appear brighter and more beautiful than a diamond with a higher color or clarity grade but weaker proportions.
Choose the Right Color and Clarity
For many buyers, E–F color and VS1–VS2 clarity offer an excellent balance of beauty and value. These diamonds generally appear bright, white, and eye-clean while maintaining a premium appearance. The ideal grades may vary depending on the diamond shape, size, and setting.
Compare Diamond Shapes
Choosing the right diamond shape is an important part of the buying process. Round Brilliant diamonds are known for maximum sparkle, while Oval, Pear, Marquise, and Emerald diamonds may offer a larger face-up appearance than Round diamonds of a similar carat weight.
Review Measurements and Proportions
Carat measures weight rather than visible size. Two diamonds with the same carat weight can look different depending on their dimensions, depth, table, and overall proportions. Reviewing measurements helps you understand how large the diamond will appear when viewed from above.
Verify Independent Certification
Always review the diamond's independent grading report before purchasing. Certification confirms essential quality characteristics and allows you to compare diamonds accurately and confidently.
