Lab Grown Diamonds
Lab grown diamonds are transforming the world of fine jewellery, offering a modern alternative to traditionally mined stones. Chemically, physically, and visually identical to natural diamonds, they deliver the same brilliance, fire, and durability but with a more sustainable approach.
With over 60 years of expertise in natural diamonds, we bring the same care and precision to lab grown diamonds. Whether you're exploring options for an engagement ring or simply researching, we’re here to guide you with honest, expert advice - not sales pressure.
What are lab grown diamonds?
Lab grown diamonds are real diamonds created in controlled environments using advanced technology that replicates the natural formation process. They are composed of pure carbon and share the exact same structure and properties as mined diamonds.
Lab grown vs. natural diamonds
Lab grown and natural diamonds look and perform the same. Both have a perfect 10 on the Mohs scale, share identical chemical composition, and sparkle with the same brilliance and fire. To the naked eye and even under professional inspection they are virtually indistinguishable.
The main differences are origin, price, and rarity. Natural diamonds form over billions of years beneath the Earth, making them rare and highly valued, while lab grown diamonds are created in weeks, often at a more affordable price. Choosing between lab grown vs natural diamonds comes down to personal preference, values, and budget, helping you find the diamond that best matches your style and priorities.
Benefits of lab grown diamonds
Sustainable
Created in controlled environments, lab grown diamonds reduce the environmental impact associated with mining.

Lab grown diamonds FAQs
Yes, they are chemically and physically identical to natural diamonds.
There are two main methods used to create lab grown diamonds:
1. HPHT (High Pressure High Temperature)
This process replicates the extreme heat and pressure found deep within the Earth, forming a diamond from carbon under
controlled conditions.
2. CVD (Chemical Vapour Deposition)
A diamond seed is placed in a chamber filled
with carbon rich gas. As the gas is activated, layers of carbon build up to
form a diamond with exceptional purity.
Not without specialised equipment. To the eye, they look the same.
Yes, they have the same hardness and durability as natural diamonds.
Yes, they are typically more affordable due to lower production costs.
Yes, they offer a transparent and traceable alternative to mined diamonds.
They generally do not retain value in the same way as natural diamonds, which are rarer.
Lab grown diamonds are chemically identical to natural diamonds and extremely durable, scoring a 10 on the Mohs scale. Moissanite is slightly softer and has a different sparkle, often rainbow-like. The choice comes down to whether you prefer diamond authenticity or moissanite’s affordability.
