Frequently asked questions

What are lab-grown diamonds?

Lab-grown diamonds are real diamonds created in a laboratory using advanced technology that replicates the natural diamond growing process. They are chemically, physically, and optically identical to mined diamonds.

 Are lab-grown diamonds real diamonds?

Yes! Lab-grown diamonds are 100% real diamonds. They have the same sparkle, hardness, and durability as mined diamonds - just without the environmental and ethical concerns.

Can you tell the difference between a lab-grown and a natural diamond?

No, not with the naked eye. Even trained gemologists need specialised equipment to identify the origin. Lab-grown diamonds are visually and chemically identical to natural ones.

How are lab-grown diamonds made?

They’re created using either High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) methods, both of which simulate the conditions under which diamonds form in the earth.

What metals do you use in your jewellery?

We use high-quality materials such as 18k gold, 18k white gold, platinum, and sterling silver. Each piece is made to last and finished to the highest standard.

Are your pieces hypoallergenic?

Yes, all of our jewellery is made with skin-friendly, hypoallergenic materials, perfect for sensitive skin.

Are lab-grown diamonds better for the environment?

Yes. Lab-grown diamonds have a much lower environmental impact than mined diamonds, using fewer resources and avoiding the disruption of ecosystems.

 Is your jewellery ethically made?

100%. We’re committed to transparency, sustainability, and fair working conditions. All our pieces are produced responsibly and ethically.
