This Byzantine link necklace is the classic of all classics: its pattern of ovals encasing different size ovals gives the this timeless design a maze-like intricacy.  This necklace is 18" long and its thick links range from 3.8MM to 1.3MM.  Of course, each oval is soldered, because if it's expected to last a lifetime, it should be flawless from the start.  The T toggle closure is very secure and both comfortable and easy to put on and off.
