This collection of rings contains 1.91 troy ounces of 15ga 12/20 goldfill in a variety of inch-size ring diameters. If you prefer, you can also purchase single ounces of assorted 12/20 goldfill rings. And if you’d rather work in millimeters? There’s a collection of 15ga 12/20 goldfill rings in millimeter sizes.
This collection includes:
size 13:15 – 0.66 ozt
size 15:15 – 0.02 ozt

size 20:15 – 0.93 ozt
size 21:15 – 0.11 ozt
These rings are made from wire with a 12K layer of gold over a brass core. My usual goldfill rings are 14K instead.
When I first started making goldfill rings, I opted for 12/20 goldfill (12K over brass, with the gold being 1/20th of the total thickness). At the time, I thought it was a clever choice because 12/20 goldfill is slightly cheaper than 14/20 goldfill. But it’s also not quite as “gold” in color and after working with them for a little while I decided to switch to the more richly colored 14K version.
Here you see the last echoes of my 12/20 goldfill experiment. These rings have been languishing in dusty boxes for over a decade, waiting for me to find them a home. Adopt them!
