Jan & Maria Biżuteria is a Polish jewelry brand centered on handmade designs crafted from 99. 9% pure copper. The brand says Jan and Maria have created its pieces for more than forty years, shaping each item by hand and emphasizing careful detailing, uncoated metal, and small-scale craftsmanship.

Its collection includes women’s bracelets, earrings, rings, ankle bracelets, and necklaces, as well as men’s jewelry and selected home and health products. Featured designs include the Petal copper bracelet, copper ankle bracelet, and Laurus ring. The website presents the jewelry as durable pieces intended for everyday wear, while customer stories describe personal experiences; these are testimonials rather than verified product or health claims.

Jan & Maria sells through its online store, where customers can browse current collections, follow orders, and find contact and customer-service information. The site advertises free delivery within Poland, a 30-day guarantee, and customer support available around the clock. It also promotes a clearance sale on selected designs and offers tiered discounts for purchasing multiple items
