Frequently asked questions
Are your diamonds laboratory-grown?
Yes. Every Nellys Diamonds stone is laboratory-grown: the same carbon crystal as a diamond from the ground, with the same hardness, fire and sparkle, formed in weeks rather than over millions of years. Every diamond is E colour, which is colourless, and VVS2 clarity, which means any tiny natural marks are very hard to see even under 10 times magnification.
How does delivery work?
UK orders are sent tracked, signed for and fully insured, always free. Engagement rings and custom pieces are made for you and take 4 to 6 weeks.
How do I look after my jewellery?
Store each item separately in its Nellys Diamonds pouch or box. Remove jewellery before swimming, exercise or applying lotions, and clean gently with warm soapy water and a soft brush.
What if it isn’t quite right?
Get in touch within 30 days of delivery and we’ll arrange a return or exchange. Rings, bespoke jewellery and anything made to order, personalised or resized for you can’t be returned for a change of mind, but your rights if anything is faulty are never affected.
