This handmade signet ring is covered in small scratch details which gives a unique vintage look. The front of the ring has a diagonal crack in it, visualizing an abstract thunder strike, thus the name Thor. As a finish, the ring firstly has been oxidized (blackened) and then polished to create a shiny yet vintage texture. The ring is made from ethically sourced .925 sterling silver. Every piece from LEF jewelry is produced in Amsterdam by the founder Detlef himself. All pieces are made and finished by hand which ensures the highest quality en makes every piece unique. Wiping the jewelry gently with a soft cloth to remove any dirt and oils after each wear will help to protect and prolong the look. It is advisable not to wear the jewelry into a swimming pool, Jacuzzi, sauna/steam room; or whilst exercising, bathing, showering or doing heavy duty tasks. If a piece is exposed to water, then dry it gently & thoroughly with a soft cloth as moisture can cause tarnishing.
