This 14 karat gold-filled ring is 1/4" wide and adjustable. It's been stamped by hand with 'moon of my life' (inspired by Game of Thrones) in a font called Wonderland.
I make this style of ring by first cutting out a 1/4" wide strip from sheet metal. I stamp the message one letter at a time, then use a stone wheel on my bench grinder to grind away the sharp corners and round the ends, then sand all the edges, hammer the ring into shape on a steel mandrel, and tumble it for a couple of hours until it gleams. I then darken the letters with black ink and give the ring a final polish and buffing.
This style of ring can hold approximately 25 letters and spaces, though this number depends on the ring size (though it's adjustable, I always recommend that people give their ring size to ensure a comfortable fit; I can make this ring in any size from 3 to 15, including half sizes). It's shown here stamped on the outside, but it can just as easily be stamped on the inside for a 'secret message' ring. It's also possible to stamp both sides, for those who want a public message and a private one.
Gold-filled jewelry, also known as "rolled gold" or "rolled gold plate" is composed of a solid layer of gold bonded with heat and pressure to a base metal such as brass. Some high quality gold-filled pieces have the same appearance as 14 karat (58%) gold. Unlike "gold plated" items, gold filled jewelry can - with the proper care - last for decades or longer.
