7cm dimeter on the circle! Made from laser cut acrylic with silver plated fastenings. All laser cut with my laser cutter, designed and finished by me, the shop owner, in my studio. 100% hand made. If you have particular colours or a custom request in mind, feel free to ask! Made to order. Avoid heavy use of perfume as this can interfere with the plastic and metal parts. A little love and care and your jewellery should last a life time.
