Our Mystery Boxes are heavily discounted surprise sets. Because each box is curated just for you based on your selected color and size preferences — and due to the nature of the surprise — returns or exchanges are not possible.
By purchasing this product, you agree to the following:
-
The contents are a mystery — you will not know exactly what you’re getting.
-
All boxes are final sale and non-returnable, unless an item arrives damaged or faulty.
-
You are receiving a significant discount (up to 60% off retail value), which is why returns cannot be accepted.
We encourage you to only order if you're comfortable with the surprise element and love discovering new jewelry styles!
