We decided to use for all our handmade designs only natural stones that are undyed and not treated with heat or any other treatment.
We carefully ethically source the semiprecious gemstones from all over the world.
All designs are handmade in our lab in Warsaw or Milano.
Freshwater Pearls
Freshwater pearls with high grade are nature’s exquisite gift to the world of jewellery.
We source our freshwater pearls ethically from China, where the tradition of pearls cultivation has a long history.
We use only pearls with high grade of luster of AAA+ or higher for every pearl. Every pearl must pass a tight quality check before being used in our piece.
We use silk thread and traditional hand knotting technique for each piece made of pearl. Each pearl is individually knotted to ensure safety of each bead. Traditional knotting is an old technique used in high jewellery that required time and an expert hand to be perfectly master, but ensure high quality of the piece.
