FAQ – Breast Milk Jewelry and Other Questions


You should receive an e-mail to the e-mail address you entered upon ordering with the complete instructions on how and where to send in your breast milk. If you do not receive anything, please make sure of two things:

  1. You completed your order, no payment is pending, and you receive confirmation of your order through your e-mail.
  2. The e-mail hello(at)yourbreastmilk(dot)com did not go to your Spam folder

Here are the instructions below:

You will need to send at least 2 tsps of your breast milk per jewelry pendant and/or 1tsp per large soap via USPS First Class Mail / Priority Mail (if within US) using a milk collection bottle. No need for dry ice packs. USPS allows sending liquids, but just make sure the breast milk does not spill.

Please label the outside of the bag with your order #.

USPS First Class Mail will suffice for shipping as it should only weigh less than 1oz. Please reply back to me with your tracking number. Other shipping carriers or options are fine (FedEx, UPS, DHL, USPS Priority, etc.) as long as the package is trackable. International orders are accepted. I will send your final order insured, but the breast milk you send to me does not need to be insured, unless you prefer..


Time frame:

Within the US: Please allow about 5-10 business days for your breast milk jewelry to be completed, shipped, and delivered to you once I receive your breast milk in the mail. During holidays, please allow up to 15 days.

Outside the US: 10-15 days for completion, slightly more for holidays. Please take into account duty fees, which you will have to take care of your own.


If this is a gift, please let me know in the notes section when checking out or e-mail so I make sure that there is no packing slip included.

Your breast milk does not have to be fresh at all. It can be previously frozen. The color of your breast milk will affect the look of your breast milk jewelry, so send in breast milk that isn’t already completely rancid. Please send in thawed milk however and not frozen to avoid possible condensation inside your package.

Unlike other breast milk jewelers, Precious Mammaries is the only store that extracts your very own breast milk’s unique imprint, displaying a “thumbprint”-like pattern that is completely unique to you, the mom and the quality of your milk at the time you expressed your milk. This means that no two breast milk stones are alike, and other moms who might order the same piece of jewelry will not have a stone that looks like yours!

This is great news for you because this assures that your very milk is used in the making of the jewelry and is truly authentically unique.

To make this happen, a clear magnifying shatter-proof glass covers the imprint like a dome, and this is what makes up the stone.

My process is proprietary, but rest assured that your breast milk will not discolor, rot, or mold throughout the years.

Because my process is efficient, all I need from you is 2 tsps of breast milk per jewelry pendant or 1tsp of milk per large soap.

It is not recommended to shower, bathe, or swim with your breast milk jewelry on. Please see this page for more important breast milk jewelry care instructions.

For the most part it will look like how it’s pictured, unless you specifically ask for a custom jewelry piece made. Also, your breast milk is unique to you. The preservation process from Precious Mammaries is different than any other store, so do not expect it to look like other breast milk jewelry in the market.

Your stone will not look like a bead. Instead, your preserved milk will be encased under clear, shatter-proof glass. You will be able to see your breast milk’s imprint, or “thumbprint,” completely unique to your DNA.

I currently do not sell or plan to sell breast milk jewelry DIY kits in the near future.

Yes, I accept custom orders. Just send me an e-mail!

Etsy does not allow the sale of certain items such as human bodily fluids. This means breast milk jewelry made from human breast milk is not allowed on Etsy.

Yes most definitely! I can make jewelry with surgical stainless steel.

If you take your jewelry apart and get to the stone without its setting, a DNA test should confirm that it is your breast milk.

Yes of course. Each jewelry automatically comes with a three month warranty. You just pay to send your jewelry back. I will cover the return shipping. Beyond three months, you pay for the shipping both ways and a small $10 fee for repair.

Yes, you may! Just see the drop-down options for “Add-Ons” in each product page. If you have a specific material in mind that isn’t listed, just send me an e-mail beforehand to ask.

Physical/digital gift certificates are available to be purchased and sent directly to the recipient or to you. Gift wrapping options are available at checkout should you choose to pick the item yourself.

I can consider your request through e-mail. Please provide proof of your organization, event, website/social media, and steps in promoting Precious Mammaries in exchange for the donation.
