Ring Blanks

All of our ring blanks are seamless and manufactured from either washers or tubing.

Those metals that cannot be deformed easily are rolled to the appropriate gauge of flat sheet and a washer is cut. The maximum width for a ring produced from a washer is 9.5MM. Tubing is used for the more ductile metals that can withstand the stresses involved in tube forming.

Blanks are parted from the tube, allowing wider blanks to be produced when compared to those manufactured from washers - up to 14MM wide.

Our tubing dimensions are set based on our finger sizes.

Determine outside dimension:
20.5mm outside dimention with a 14mm inside dimension. (SZ 4 TO 5.5)
22.5mm outside dimension with a 16mm inside dimension (SZ 6 TO 7.5)
24mm outside dimension with a 17mm inside dimension (SZ 8 TO 9.5)
25.5mm outside dimension with a 19mm inside dimension (SZ 10 TO 12.5)

Determine the finger size in millimeters:
Example: SIZE 6 = 16.5MM

Determine the height of the band needed:

Multiply your height times 2:

Finger size plus the height (X2) to get OD:
EXAMPLE: 16.5MM + 4MM = 20.5MM

Determine Circumference:
From a Flat Sheet:
Finger Size plus the height (X2) times 3.14
.648" + .160" = .808"
.808" x 3.14 = 2.537"
