A birthday gift that could only ever be theirs.

About 3 to 4 weeks if you want the finished piece on the day. The kit reaches you in 2 to 3 working days, and the piece takes 2 to 3 weeks from the day the laboratory has the swab. The gap between is however long they take to swab. Closer than that, give the kit on the day and let the piece follow.

For a 21st or a first piece of real jewellery, the Silver DNA Profile Necklace at £249 is the classic. For a 30th, 40th or 50th, the Pearl DNA Profile Necklace at £275 or the Gold DNA Profile Necklace at £699 carry more weight. Bracelets from £179 suit anyone who does not wear necklaces.

Yes, with written consent from a parent or guardian with parental responsibility, which the form in the kit covers. A 16 or 17 year old consents for themselves.

No. They rub the swab inside their cheek for about a minute, seal it, sign the form and post it in the prepaid envelope. No blood, no appointment, nothing to pay.

A special birthday gift is one that could not have been bought for anyone else. A DesigNA piece is made from the person's own DNA profile, so the order of its stones exists once. The Silver DNA Profile Necklace at £249 is the one most people start with, and the Twisted Pearl DNA Profile Bracelet at £229 suits someone who wears bracelets. Both arrive boxed with a signed certificate in their name.

Something that cannot be duplicated. Someone who has everything already owns the engraved, the monogrammed and the birthstone versions of most things. A DNA necklace is made from them, so it is the one piece nobody else can give. See DNA necklaces from £249 or DNA bracelets from £179.

The Pearl DNA Profile Necklace at £275 is the most gifted piece for a woman's birthday: freshwater pearls with her own markers set between them as natural stones. For something lighter, the Spider Pearl and Gold DNA Profile Bracelet at £199 sits fine on the wrist and adjusts with a slider.

A bracelet he can explain. The Twisted Silver and Gold DNA Profile Bracelet at £229 and the Spider Silver and Gold DNA Profile Bracelet at £199 are quiet pieces in silver with gold markers and no stones, so they read as a pattern rather than a decoration. The pattern is his own profile, which is usually the part that wins him over.

Yes, because a milestone birthday asks for something that marks the person rather than the number. Silver suits a 21st, pearl a 30th or 40th, and the Gold DNA Profile Necklace at £699 is the fiftieth birthday piece. Every one comes with a certificate that records the profile it was made from.

You can. The kit itself is the gift on the day: it arrives in 2 to 3 working days in the DesigNA box, they take the swab, and the finished piece follows. If there is no time even for the kit, the DesigNA gift card from £50 arrives by email and lets them choose the piece. The DNA Representation Pendant at £80 ships from stock in 2 to 3 days with no swab needed.

You can surprise them with the kit, not with the swab. An adult's DNA is analysed only with their own consent, so the person who will wear the piece takes their own swab. Most people find the reveal works better anyway: the kit is the moment, and the piece arrives a few weeks later as a second one.

Nothing is lost if you guess. Necklaces come in 16, 18 or 20 inches and every one carries a 2 inch extender, and every bracelet adjusts on the wrist with an extender chain or a slider.

Yes. The price of the piece covers the kit, the laboratory work, the making, the signed certificate, the box and free UK tracked delivery for both parcels. There is nothing to add at checkout.
