A: Breast milk jewelry is a one-of-a-kind piece created especially for you, using your own breast milk.

Rather than simply adding liquid milk, the breast milk is carefully preserved so it can last safely within the gem.

Each piece goes through a delicate, individualized process, as no two pieces are ever the same.

A: We value your trust as deeply as the bond between mother and child. As part of our process, we record the breastmilk preservation stage and send you a private video link to the email address used for your order. By sharing this step, we hope to offer reassurance and a closer connection to the creation of your jewelry.The video link is shared only with you and will not be made public. Breastmilk jewelry is a deeply personal keepsake that symbolizes a mother’s love for her child. We are honored to create each piece and to share this meaningful part of the process with you.

A: Each product is unique, like the breastfeeding journey it comes from. Some breastmilk is high in fat, some cannot be crushed as small, some is light, some is dark, and some are thin. Each type of breast milk is what your baby needed at the time of your breastfeeding. We capture the essence of breast milk and preserve your memories.

A: Each piece is carefully handcrafted, not machine-made. Because of this, every piece is unique—no two will ever be exactly the same, even when created using the same materials.

As a natural result of the handmade process, slight variations in color, tone, or shape may occur. Even when the same breast milk is used, differences in color intensity or hue can appear. We do our best to preserve the natural appearance of the breast milk, honoring its individuality. Small air bubbles may also be present, as each piece is made by hand.

These characteristics do not affect the durability or longevity of your jewelry. We take great pride in every piece we create and offer a warranty for your peace of mind. Please refer to our Terms and Conditions page for full warranty warranty information.

A: Yes, if you have multiple children and have breastmilk from each feeding period, you can mix them together to make a product. If you would like to make multiple products separately, you can use breastmilk from one child for each product. Please contact us in advance if you would like to make a product using multiple breastmilks if it is not in the listing.

A: Yes, you can. Other things will only be added if you select the additional option.

A: Please refer here for jewelry care instructions.

A: For the safety and health of our customers, we do not sell kits that allow you to make your own. The materials used in breastmilk jewelry contain substances that can be dangerous to the maker and their family. I wear a special mask when I work, and my workshop is equipped with special ventilation systems.

Another reason is that our pieces are made with specialized tools and techniques for jewelry making. The creator spent years learning from jewelers, other keepsake artists, and jewelry schools. We have dedicated workshops for all materials, tools, and equipment, so our pieces cannot be made in a makeshift workshop like a table at home with the same quality.

A: Sakura Milk Jewelry offers two types of crushed opal: Bello Opal (Synthetic) and Ethiopian Opal (AAA gem quality). Bello Opal (Synthetic) has a vibrant color that is easy to see, making it ideal for creating a striking gem effects. Ethiopian Opal, on the other hand, has a softer glow that is visible when the light hits it directly.
Some customers may be hesitant to use synthetic opal, but in terms of appearance, synthetic bello opal creates a more beautiful look for jewelry.

A: The tiny umbilical cord that has dried and fallen from a baby's belly button can be turned into jewelry as a precious keepsake. It's difficult to store as is; in Japan's humid climate, it can easily get moldy. Furthermore, its small size makes it easy to lose. Also, if you store it in an umbilical cord case, it's rarely seen, and the case takes up space in your keepsake collection. The umbilical cord connects us to our baby in the womb. In some cultures, keeping your baby's umbilical cord close to you is believed to bring you closer to your child or to bring back something loving and precious as you get older.

A: Yes, many of our product listings have this option.

A: There are no special requirements, but to prevent loss, we ask that you use a tracking system for shipping. Please refer to the following for packaging instructions.

A: No, you can send us any part or all of the cord you want. It's fine if it's broken into pieces. However, if you would like the whole cord to be kept as a keepsake, please find a suitable size keepsake and let us know. If you send us the whole cord and some of it doesn't fit, we will carefully pack it together with the keepsake and return it to you.
