Why Choose Us

1. Fake Breast milk?

Can you tell the difference between the 2 charms? Thanks to our Chemist, we found that some makers use coloured dyes instead of real breastmilk to pass off as preserved breastmilk. As a mother, I can only imagine the pain if I found that my precious breastmilk jewellery made so many years ago is nothing but a scam. By then, I will no longer have any breastmilk left to make it from ethical sources.

At Keepsake by Ryo, we engage a chemist to formulate a secret breastmilk preservation method so that your breastmilk keepsake will not rot and decay over time. We are the first to do it and our secret method has never been leaked. Since our innovation, many other keepsake makers claim to be able to do so in the matter of days. If you have tried to DIY your own breastmilk keepsake at home, you would have found that signs of decay will show in a couple of weeks or months. Thanks to an anonymous tip and the help of our chemist we finally found out how other makers "did" it.

To authenticate our products, we will regularly conduct workshops so that mothers can make their own keepsake and visually see that only your own breastmilk is used in the making of your keepsake.

3. Customized Charm Cores

Some people ask us why we customize our own 925 silver charm cores when we can purchase them from open sources like Aliexpress and Taobao? This is because we noticed that charm cores from open sources tend to tarnish faster despite their 925 stamps, as their silver concentration is questionable. They also have a tendency to drop off when rubbed against your bracelet or bangle due to its small size and light weight.

So, we customized our own charm cores to ensure its quality, also making it bigger and heavier to prevent it from dropping off or tarnishing easily. Notice that from the front our charm cores are bigger and shinier and from the back the open source charm cores are actually hollow on the inside.

Our charm cores are >10x more expensive. Also the gold and rose gold vermeil versions cannot be found in the open market and are only available at Keepsake by Ryo.


4. Keepsake by Ryo has got a 1 year warranty period against breastmilk discolouration due to decay and a full refund policy.

5. Resin Quality

Did you know that Keepsake by Ryo uses a unique resin that is heavily R&D to have higher resistance against sunlight and yellowing than our previously used ICE RESIN™ in our casting process? Our resin is 8 times more expensive than other commercial resins and is not commercially available in Singapore. As part of our commitment to deliver the best quality handcrafted jewellery to you, we secure supplies from the USA so that our products are of highest quality. Unlike other epoxy resins which naturally appear yellowish and will continue to discolour over time with frequent wear and exposure to UV rays. Our unique resin do not have such problem and this time round we have time tested it since 2016.

6. Breastmilk Jewellery Quality

Did you know Keepsake by Ryo uses a unique method of breastmilk preservation through actual engagement of a chemist? Combined with the unique nature of unique resin formula, our charm will retain the actual colour of your breastmilk and will stand the test of time. 

7. Customized Sterling and Sterling Vermeil Silver, Gold and Rose gold Charm Cores

Did you know that Keepsake by Ryo is the only keepsake producer with Gold and Rose Gold coloured charm cores made with Gold Vermeil and Rose gold Vermeil materials? In our quest to provide you with great quality, we realized all the commercially available Gold and Rose Gold coloured charm cores are merely plated with a thin layer of precious metal, which is quick to tarnish and this tarnish is irreversible. Only 925 Silver can resist tarnish, hence we decided to customize them in Gold and Rose Gold Vermeil, which is effectively a thick layer of 24k gold around sterling silver to ensure that it will last the test of time. Only thick 925 Silver and Vermeil can resist the impact of stamping without flaking or breaking. Hence we stamp all our charm cores with our company name "KEEPSAKE BY RYO" and "S925 SINGAPORE" on the other side to proof the authenticity and quality of our cores. These cores are 10 times more expensive than commercially available plated ones and we absorb this cost without increasing our prices. You can read more about the differences in materials at,


8. Jewellery Hardware Materials and Quality.

Did you know that Keepsake by Ryo indicates all materials and hardware used in all our product descriptions? Our pricing also reflects the different types of materials used to ensure that you make an informed decision before purchasing. We urge you to invest in quality materials, but we also want every mother to be able to afford a momento of her breastfeeding journey. Hence we offer a wide range of products of different materials and pricing to cater to a wide range of tastes and preferences.

Be wary of keepsake makers who exclaim that their products will "stay like this forever". Even the purest of gold will tarnish in contact with salt water, chemicals or chlorine, and that is an irreversible chemical reaction.(Google it) To ensure that your keepsake jewellery will last, follow the jewellery care instructions in our warranty card carefully, and invest in good quality hardware metals.

9. Equipment, Machinery and Proper tools

Did you know that Keepsake by Ryo invests in a variety of equipment for purposes such as eliminating air bubbles, preserving breastmilk without affecting the colour of your breastmilk, polishing your finished product and even a vibration device to ensure a more even spread of shimmers/ colours/ glitters? We understand the importance of that one extra process to make every drop of liquid gold count.


10. Own, Unique Breastmilk Preservation Techniques

Did you know Keepsake By Ryo actually engaged a chemist to create a breastmilk preservation technique unique only to us? This is to ensure that your product will not turn yellow or black due to decay and your precious keepsake will last the test of time. This technique ensures that your jewellery will become a stable chemical compound, ensuring that you or your children are not exposed to unnecessary or harmful chemicals. Thanks to this technique, we are able to use both fresh and expired breastmilk.

Beware of keepsake DIY kits, that uses paraffin wax or poor quality resin in an attempt to earn quick buck. Such DIY kits, usually do not come with any form of preservation for your breastmilk and will turn yellowish or blackish within 3 weeks and it will only get worse as time goes by. DIY kits using paraffin wax are extremely dangerously as they produce toxic chemicals when heated. Paraffin wax is use as the main ingredient for soap and due to it's soft texture a glass globe or casing is usually provided for such DIY kits. Below is an experiment done using DIY kits in comparison to our product and the result speaks for itself.

Perimeter of experiment:

  • All casts use the same breastmilk sample, expressed in December 2015.
  • None of the DIY kits we purchased came with any air bubble removing equipment so we didn’t use our machines in the process out of fairness. (hence the uneven charms!)
  • All charms were casted at the same time, using the same molds for fairness.
  • All completed charms were then placed beside a closed window to simulate Singapore’s weather conditions.

11. Glitters, Shimmers and Flakes

Did you know all Glitters, Shimmers and Flakes are all either hand cut and/ or mixed by Ryo herself? This ensures a unique blend of colours that are only available at Keepsake By Ryo. 


12. Material Description

At Keepsake by Ryo, we strongly believe in ethical display of hardware material, so that our customers can make an informed decision before purchase. Many times, we even customize our own hardware due to the absence of our desired material quality in the open market. Till date we have customized our own charm cores, dangling charm attachments, and many more. All of which includes their respective stamping to ensure the quality of the item. Beware of Jewellery retailers that do not display the actual material of the hardware the items will tarnish or cause unnecessary allergic reaction.

13. 18k Gold 

Did you know Keepsake by Ryo, is the first and only Breastmilk Jewellery maker that uses 18k gold and real diamonds? Gold is an inert element, hence by nature it does not react (tarnish) to any other elements in the periodic table giving it a huge advantage over other jewellery making materials such as silver and stainless steel. 18k gold is an alloy with 75% gold and 25% other metals. This is the highest concentration of gold that is hard enough to hold the breastmilk jewel and diamonds. It is industry recognized for its ability to resist tarnish and is widely used for purpose like engagement rings, wedding bands and etc. Singapore having an extremely humid climate, only solid gold can last the test of time.

There is less than a 1% chance that oxidation can occur on the surface of the 18k gold, but since it is a solid metal and not a coating of gold, it can be polished using any dry jewellery cloth to restore its original luster in the really rare chance of it happening. Attached is a link for your further understanding,

 14. Quality Control

Did you know Ryo is psychotic by nature? We produce an average of 130 to 150 orders per month and Ryo personally rejects 30-50 orders monthly. Below is a picture of rejected goods that our production team nicknames "The Graveyard". T_T


 15. IT System

Did you know that Keepsake by Ryo uses a full support IT system to keep track of all inclusions received? The system will automatically send an email invoice upon the confirmation of your order. The system will then send out a second email indicating that we have received your inclusions before generating an order ID number to be labelled and boxed together with your inclusions. This box will follow through the entire process of making your item so as to eliminate occurrences of error. Upon completion, the boxes will be opened, completed items will be packed and mailed out and the system will send a third email to you with your tracking number.

Below is a picture of these boxes at their final stage before being packed and sent out. The piles of items at the front are those that have failed QC. Note that the picture is time stamped, indicating that we have all along been using this practice.

Thanks to the assistance of the system, till date we have only one attempt of sabotage. The particular person complained that she received her item even though she did not even send out her breastmilk yet. We offered a full refund or remake but yet she refuse to sent us back the product. Luckily with the records on our system, it shows that there was a first email send indicating that we have received her breastmilk, and there was a second email send indicating that we have completed and mailed our her item. For the entire duration from receiving her inclusions until the dispatch of her item, she did not reply any of our emails or indicate that we might have made a mistake. She only waited till she received the item before demanding us to make a brand new charm while refusing to return the previously sent charm. Luckily, email records don't lie.

 16. Defect/Warranty Activation and Refund Policy

19. Waiting Period

We understand that the long waiting period can be daunting and may cause anxiety to some mummies. As keepsake making is a very delicate process, different makers have a different waiting period, some as long as 7 months or longer. At Keepsake by Ryo we do our best to reduce the waiting period and have an average waiting period of less than 8 weeks from the date of receiving your inclusion. However there are many variables when it comes to handmade products hence 14 weeks is our maximum waiting period. Till date 98% of our products were made within this 14 weeks timeline, and we hope to maintain or reduce our waiting period in our aim for continuous improvement. Beware of makers with extended waiting period of 6 months or more. They usually provide door to door collection of inclusions to hide their address and constantly having promotions despite not finishing their previous orders. Internationally there are cases where maker absconded with the money (Google it).
