14K/12K Gold Filled , Jump Ring

Each size: +/-0.5mm, thickness: Approx 2mm
Color: Gold
There may be slight misalignment at the joint and uneven color at the soldered part (see video).

These are Gold Filled components (rings). This is a double-type item where a ring with an embossed surface and a plain ring are layered. (The two rings are fixed and not movable.) Gold Filled is a material (brass) with 14K gold pressure-bonded to it. When the weight of the gold is 1/20 or more of the total weight, it is called Gold Filled. The surface is completely 14K gold due to the pressure bonding, but by using brass for the invisible core (which does not touch the skin), it is characterized by an affordable price. Therefore, its appearance is similar to gold parts and differs from the appearance of plated parts. It also has the characteristic of being more durable (less likely to peel) than plating.
