This can be purchased individually now and will be a custom piece in a mystery setting. Please let us know in the comments on your order what you would like to send in eg. hair, fur, umbilical cord, cremation ash or petals or any combination of those, so we send the correct kit. Or it is a mystery piece that will be made alongside your order with the same elements but a different setting. If you have a request we will usually try our best to make it but it is not guaranteed. Does not include breastmilk jewellery – if you request this for breastmilk jewellery the order will be cancelled and refunded.

A mystery jewellery item is something that we make when we need more photographs of a new setting or variation and will be valued at at least £70. If you include as many notes as possible with your order we will try to match it, for example, “my ring size is P and I love black” or “I have a Thomas Sabo necklace” or “my mother in law likes classic jewellery and could have the same piece as me but with blues and greens”. It could be a new exclusive design!

Mystery Memorial Jewellery Engraving

Will not be engraved, sorry. Can be any combination of cremation ashes, locks of hair, umbilical cord or placenta (not breastmilk) and will be set in resin and solid sterling silver. See our rough natural birthstone options for resin memorial jewellery here and tick the box to include one, let us know which you’d like in the comments.

What will I get?

Please note that there is no guarantee of what you will get but our aim is to please. As with every other piece we sell they are completely 100% custom made and non-refundable. The mystery items are also not included in our goodwill remake policy. Because they are occasionally trials of new techniques they will sometimes be more rough and handmade than our usual work (which is, honestly, rough and handmade anyway!) so please read our terms and conditions fully to understand the flaws that are possible.

    I ordered a mystery piece as I was having an ash ring made pro bono. Nikki gave excellent customer service and the mystery piece I received is truly beautiful.

    I ordered a mystery piece hoping that I would get a ring with some of my Dads hair in it. I was not disappointed at all – I received the most beautiful heart shaped ring with my dads hair in it – it is absolutely beautiful & fits perfectly. Communication was great, I changed my ring size preference & this was no trouble. I will treasure this ring forever. Thank you to Nikki & the team for making such a special piece of memorial jewellery for me. I 100% recommend Tree of Opals.

    I ordered a mystery piece and sent in some of my breast milk. I was hoping for a breast milk pendant. The most beautiful orb pendant on a silver chain arrived & I could not be happier with it. Nikki included the colours of the months of my 3 children’s birth that you can see in certain lights. This is such a beautiful reminder of my breast feeding journey with 3 children & again I will treasure it forever. Thank you so much.

    I am honestly so happy with my mystery jewellery, yes, the wait for it is long, but Nikki and her team don’t hide it when you order, and it was so worth the wait! My ring was to comemorate my breast feeding journey, I which I knew was coming to an end, my ring aptly arrived one week after my last feed, so was that bit more special to receive!
    The quality of the ring is outstanding, I’m quite fussy with jewellery so was detailed as to what I didn’t like when I placed my order, what I received was far better than I expected and packaged beautifully. Thank you Nikki and team, you’ve made me very happy!

    I ordered a mystery item, and sent some umbilical cord. My requests were matched so well, and it was exciting to take delivery of to see what had been made! I received a gorgeous ring to celebrate the birth of my daughter, utilising her birthstone and with her name and birth date engraved. The umbilical cord itself is clearly identifiable if you look for it but subtle and very much looks like a natural inclusion (like in amber), which is perfect. Communication from Nikki and the team was great, and the quality of the piece amazing! Can’t wait to choose and order another product to mark the arrival of our second baby!

      Oh thank you so much Marisa! I just want to let everyone know we aren’t able to engrave the mystery pieces any longer but we’ll always take colour, style, birthstone, awards etc into account. These pieces are perfect for us to photograph for Instagram to show off our best work
