The ring is made from Silver 925 or Titanium. 
Fabrication  time takes about 4-6 weeks, but can be increased. don't forget it is handmade and the ring is being made the first time. 

The silver ring has a silvery white color. Titanium is black

All parameters of the ring (tire name, width, thickness of the ring, internal engraving, etc.) are indicated in a note when placing an order.

Fabrication can take from 4 to 20 weeks depending on the complexity of the rings, the number of rings in one order and my total load

Be sure to contact me before ordering and we will discuss the details.

Best regards.
