Sebastien Ring

Skydiamond is the world's first carbon-negative certified diamond. We have created the ultimate alternative, by alchemising the air we breathe into light-splintering British-made diamonds.

The first measure of a diamond’s quality is its size, measured in carats. A carat weighs one fifth of a gram or 0.2g.

Handling Your Diamonds

• When handling your jewellery, try to hold the edges of the piece or the metal setting rather than the stone itself.
• It’s advisable to remove jewellery during activities like cleaning, swimming, or gardening.
• Avoid exposing your jewellery to extreme heat or cold, as this can create internal stresses.
• Store your diamond jewellery in a fabric-lined jewellery case or keep it in a box with dividers to prevent pieces from rubbing against each other.

Cleaning Techniques

• Soak the jewellery for 20-30 minutes, then gently brush it with a soft-bristled toothbrush. Rinse under warm running water, and pat dry with a soft, lint-free cloth.
• Consider taking your jewellery to a professional at least once a year.

All orders are secured in a soft pouch made from recycled textiles. Each piece has an Skydiamond jewellery authentication card and all diamonds over 0.5carats come with an official diamond certification.

Engagement rings are delivered in an elegant bespoke hinged gift box and ribbon.
