JDG stainless steel two-piece ring core - 4 mm width

Two-piece JDG ring core in stainless steel. Stainless steel is hypoallergenic, rust-resistant and very durable. Once polished, the seam inside the ring is almost invisible. All ring cores manufactured in Ontario to strict specifications.

Ring cores are available in full and half sizes from ring sizes 4 to 12.5. Please select ring size size you want from the dropdown menu above. This is a 4 mm width ring. This refers to the width of the band you will be turning and mounting onto the ring core. Not all ring sizes are available in all widths. 

Total ring width for ring sizes 4 to 7.5 with 4 mm ring core: 
6.8 mm (4 mm for the turned band and 1.4 mm on each side for the stainless steel edge)

Total ring width for ring sizes 8 to 16 with 4 mm ring core:
7.8 mm (4 mm for the turned band and 1.9 mm on each side for the stainless steel edge)

This is a precision project. Please read the instructions carefully - you'll find them in the documents tab. Ring cores require expanding JDG ring mandrel specific to the ring size you are making. Mandrel sold separately, see related products tab for link. Watch this video on how to separate the ring core pieces from each other.
