Collection: Lab Grown Diamond Jewellery

Lab grown diamonds are real diamonds created in specialist laboratories using advanced technology that recreates the conditions in which natural diamonds form. The two principal methods are High Pressure High Temperature, known as HPHT, and Chemical Vapour Deposition, known as CVD.

Lab grown diamonds have the same physical, chemical and optical properties as natural diamonds. Each stone is carefully cut and polished to reveal its brilliance, making lab grown diamond jewellery a beautiful choice for engagements, weddings, anniversaries and meaningful gifts.

Explore our complete collection of lab grown diamond jewellery, including elegant lab grown diamond rings, sparkling lab grown diamond earrings, refined lab grown diamond necklaces and timeless lab grown diamond bracelets.

You can also discover designs from our dedicated Labgrown.Diamonds collection, featuring beautifully crafted jewellery made using certified lab grown diamonds.

The benefits of lab grown diamonds

Exceptional beauty and quality

Lab grown diamonds offer the same brilliance, durability and enduring beauty as natural diamonds. They are available in a wide choice of cuts, colours, clarities and carat weights, allowing you to choose a diamond that complements both your style and your preferred setting.

Greater choice and value

Lab grown diamonds generally cost less than comparable natural diamonds. This can allow you to consider a larger centre stone, a higher specification or a more detailed setting while remaining within your chosen budget.

A modern alternative

Created using advanced technology rather than extracted through traditional diamond mining, lab grown diamonds offer a contemporary alternative for customers looking for beautiful fine jewellery with a different origin.

What are lab grown diamonds?

Lab grown diamonds are real diamonds created in specialist laboratories. They share the same physical, chemical and optical properties as natural diamonds, including their exceptional hardness and ability to reflect light.

The principal difference is their origin. Natural diamonds form beneath the Earth’s surface over an extended period, while lab grown diamonds are created in controlled conditions using advanced technology.

Why choose a lab grown diamond?

Lab grown diamonds offer exceptional beauty and can provide greater flexibility when choosing the size, specification and style of your jewellery.

Because they generally cost less than comparable natural diamonds, you may be able to choose a larger diamond or a higher colour and clarity grade within the same budget. They offer the brilliance and durability expected from fine diamond jewellery, with a modern laboratory-created origin.

Do lab grown diamonds hold their value?

Lab grown diamond jewellery should primarily be chosen to wear, enjoy and treasure rather than as a financial investment.

As with most new jewellery, its future resale value is not guaranteed. Lab grown diamonds usually have a lower initial purchase price than comparable natural diamonds, which can also mean lower replacement values and insurance costs.

How should I care for lab grown diamond jewellery?

Clean your jewellery regularly using warm water, a small amount of mild washing-up liquid and a soft brush. Rinse it carefully and dry it with a clean, lint-free cloth.

Store each piece separately to reduce the risk of scratching or tangling. We also recommend having frequently worn jewellery professionally cleaned and checked periodically, particularly engagement rings and other pieces worn every day.

Are all lab grown diamonds certified?

Not every lab grown diamond is individually certified. Very small diamonds, often described as melee stones and typically weighing less than 0.25ct, are rarely supplied with individual grading reports. Some larger diamonds may also be offered without certification.

At Avanti Jewellers, we believe that a principal lab grown diamond weighing 0.50ct or more should be accompanied by an independent grading report from a recognised laboratory such as the IGI or GIA.

This report provides an independent assessment of the diamond’s carat weight, colour, clarity and other important characteristics, giving you greater confidence when choosing your jewellery.
