Yes, our lab-grown diamonds are 100% real diamonds. They are created in a controlled laboratory using advanced technology that replicates the natural diamond-growing process.

They have the same chemical composition, hardness, brilliance, sparkle, and beauty as mined diamonds. The only difference is their origin — lab-grown diamonds are grown in a laboratory instead of being mined from the earth.

They are not cubic zirconia and not moissanite. They are genuine diamonds, made to last a lifetime.

Lab-grown diamonds are a beautiful choice for customers who want the luxury, sparkle, and durability of a real diamond with excellent value.

They allow you to choose a larger or higher-quality diamond within your budget, without compromising on beauty. You still get the same brilliance, hardness, and timeless look as a mined diamond.

They are also a modern and responsible alternative to mined diamonds, making them perfect for engagement rings, wedding rings, anniversary gifts, and everyday fine jewellery.

With lab-grown diamonds, you can enjoy real diamond beauty, better value, and a meaningful choice for your special moment.

No, not by looking at it. Lab-grown diamonds have the same sparkle, brilliance, and beauty as mined diamonds, so they look stunning in everyday wear.

You do not need to visit a gemologist or specialist to check your diamond, as we provide an IGI certificate. This certificate confirms the diamond’s 4Cs — carat, colour, clarity, and cut — along with its lab-grown origin.

You can also verify your diamond online using the IGI report number, giving you complete confidence in the quality and authenticity of your diamond.

The 4Cs are used to describe diamond quality:

Carat – the weight and size of the diamond.

Colour – how white or colourless the diamond appears.

Clarity – how clean the diamond looks inside.

Cut – how well the diamond reflects light and sparkles. The cut is very important because it affects the sparkle, fire, and brilliance of the diamond.

At Carbonstone UK, we carefully select diamonds to give a beautiful balance of quality, sparkle, and value.

Every diamond is hand-picked by our experienced team. Our diamond experts have over 15 years of experience in selecting high-quality diamonds for fine jewellery.

We carefully check each diamond for its cut, colour, clarity, carat weight, sparkle, measurements, and overall appearance. We only select diamonds that meet our quality standards and suit the design of your jewellery.

Once our expert team is fully satisfied with the diamond, we will share the diamond photos, videos, and certificate details with you where available. This gives you confidence and transparency before your jewellery is made.

At Carbonstone UK, we never compromise on quality. Every diamond is chosen with care to give your jewellery the best balance of beauty, brilliance, value, and long-lasting wear.

Yes, where available, we can share diamond details, images, videos, or certificate information before production begins.

This helps you choose with confidence and understand exactly what diamond will be used in your jewellery.

Yes, we provide a FREE IGI certificate for the centre diamond to give our customers complete confidence, authenticity, and transparency.

The IGI certificate includes the diamond’s important details, such as carat weight, colour, clarity, cut, measurements, and lab-grown diamond origin.

You can also verify your diamond online using the IGI report number, giving you peace of mind that your diamond is genuine, certified, and carefully selected.

At Carbonstone UK, we never compromise on quality. We believe trust is very important when buying fine jewellery online, so we provide clear diamond certification to help you buy with confidence.

Yes, if you would like an IGI Jewellery Report for the complete finished jewellery piece, we can provide this as an add-on service.

An IGI Jewellery Report gives more detailed information about the full jewellery item, including mounted gemstones, metal details, purity stamps where present, and clear photos showing craftsmanship and finishing details.

This report is different from the centre diamond certificate because it focuses on the complete jewellery piece, not only the loose or centre diamond.

You can add the IGI Jewellery Report while placing your order by selecting it from our add-on services and adding it to your basket. This service is available at an extra cost and may require additional processing time. (If you have already placed your order or need help adding this service, please message us and we will be happy to assist.)

Yes, you can verify your IGI diamond certificate online using the IGI report number.

We provide a FREE IGI certificate for the centre diamond where applicable. After placing your order, we will share your diamond details with you, including diamond photos, videos, and the IGI certificate where available. This allows you to check the diamond details online through the IGI website and gives you full confidence before your jewellery is made.

For bespoke or customised jewellery, once your design is confirmed, we will share the diamond information based on your selected design, including the diamond photos/videos and certificate details where applicable. We will also keep you updated throughout the making process.

After your jewellery is completed, we will share final photos and videos before dispatch. If you have selected the IGI Jewellery Report as an add-on service, we will also provide the IGI Jewellery Report details once available, so you can verify the complete finished jewellery piece online.

This means you can verify:

1. The centre diamond IGI certificate — provided free certificate for the centre diamond
2. The finished jewellery IGI Jewellery Report — available as an add-on service

The centre diamond IGI certificate gives confidence in the diamond quality and origin, while the IGI Jewellery Report gives additional information about the complete finished jewellery piece.
