FAQ
Yes, our pearls are real freshwater cultured pearls. Real pearls are organic gems, so each one can have slight variations in shape and surface – this is normal and part of their natural character.
At this price point (USD 39–79), issuing an individual gemstone certificate for every piece would add a lot of extra cost, so we focus our budget on better pearl quality and craftsmanship instead.
Instead of charging you for a paper, we:
- Source directly from our own workshop and long-term partners
- Inspect every piece multiple times before shipping
- Clearly show close-up photos and videos so you can see the real surface and luster
If you would like a third-party certificate for a higher value order, please contact us and we'll do our best to help.
