New Jewelry Case

Many materials around us — from straws and shopping bags to packaging cases — are shifting from plastic to paper. Paper is, of course, a more sustainable material in terms of decomposition and recyclability. It doesn’t release microplastics that pollute the ocean.
However, producing paper requires cutting down precious trees and emits more carbon during manufacturing than plastic. For us — a brand that uses hundreds of paper cases each day — this was a serious concern.

That is why we turned to “Limestone Bio Compound”, an eco-friendly composite made primarily from limestone. Limestone is a sedimentary rock composed of calcium carbonate (CaCO₃) — yes, the very same “stone” we pass by every day without noticing. Made from finely ground rock, this material is as durable as plastic yet more environmentally responsible than paper.

We wanted our jewelry case to be more than just packaging — to be a work of art in itself. It serves beautifully as both a jewelry box and a gift package, and even with the lid closed, it can be used as a jewelry tray to display your favorite pieces elegantly.

From material selection to production, the process took more than five months — a reflection of our sincere commitment.
At COLDFRAME, we will continue striving to offer experiences that are not only beautiful, but truly meaningful.
