Q&A

Jewelry can be created with as little as 2ml of breastmilk.

The average amount of breastmilk required is approximately:

1–2 pieces of jewelry: 2ml–10ml
3 pieces of jewelry: Approximately 10ml
4–6 pieces of jewelry: Approximately 10ml–20ml

If you are sending less than 5ml of breastmilk, please send it in one container without dividing it into smaller portions, and use frozen shipping whenever possible to help prevent leakage during transit.

If you would like to create three or more pieces of jewelry using only 2ml of breastmilk, please contact us in advance to discuss your order.

To help preserve the quality of your breastmilk, we recommend shipping it using a refrigerated or chilled delivery service whenever possible.

Breastmilk may also be sent using standard shipping during cooler weather; however, this may increase the possibility of slight color changes in the finished jewelry. If preserving the original color as much as possible is important to you, we recommend using a refrigerated shipping service.

If your order does not include breastmilk, you may use any shipping method. However, we strongly recommend using a tracked shipping service to help prevent loss during transit.

We value your trust as deeply as we value the bond between mother and child.

As part of our breastmilk preservation process, we record a video of your breastmilk being preserved and send you a private viewing link to the email address used for your order. We hope this special glimpse into the creation of your keepsake helps you feel connected to the journey of transforming your breastmilk into jewelry.

If you ever lose access to your private link, simply contact us with your order number and we will be happy to resend it.

Your preservation video is private and will never be shared with anyone other than you.

Breastmilk jewelry represents a deeply personal symbol of love and connection between a mother and her child. It is our privilege to create these meaningful keepsakes, and we are honored to share a part of that experience with you.
