Niobium Jump Rings - Color
Niobium is a reactive metal. It receives its color due to anodizing with electricity. Batches of Niobium can be slightly different colors, just like dye lots, so be sure to purchase enough rings at one time to complete your project. 

Since both electricity and light angle effect the color of Niobium, different sizes may not match exactly. Also, different gauges will look slightly different as the thickness of the different gauges reflect the light at different angles.

There can be a variation of color occurring in varying amounts from ring to ring and from batch to batch with Niobium. This color variation is a feature property that adds to the beauty of Niobium.

We anodize the rings after they are cut, so the color completely covers the ring, even the cut end.

Niobium Jump Rings - Cleaning 
Oils from the skin can make your Niobium seem dull.  To clean Niobium, use a window cleaner (such as Windex) to polish.  Rinse and dry your piece completely to bring back the shine. 

Niobium Jump Rings - Specifications
Our jump rings follow the American Wire Gauge (AWG), also known as Brown and Sharpe (B&S). All sizes listed are inside diameter (I.D.), measured in millimeters which corresponds to the size of the mandrel onto which the wire is wound. Use these I.D.'s as a guide not an absolute. The wire used to make our jump rings is of extremely high quality and made using an IOS-Certified production process. However, like all wire, there may be slight tolerances in size. Wire diameter may vary up to 0.03mm (0.0012”) larger or smaller than the listed size.

Occasionally you might get a misshapen ring or an end cut half ring. To account for this, we put extra rings in every bag.

Niobium is not available for returns or exchanges

 **Important Notice: Orders with more than 2 packs of an item may be bulk packaged at WGM's discretion. However, colors and sizes will not be mixed in a bag.

    Unanodized niobium 20g jump rings are cut well

    Sep 13th 2017

    It's sometimes hard to find unanodized jump rings but Weave Got Maille has got that covered. That allows me to make a piece, tumble it, and then anodize it. Their jump rings are well cut with no burrs and competitive prices are the icing on the cupcake!

    I have purchased from WGM before (wholesale batch) and had a great experience. This purchase was no exception. The rings I received are gorgeous and just as expected with quality and color. I will purchase again in the future.

    No burrs & nicely cut

    Oct 24th 2016

    I cut my own jump rings but can't cut niobium so, I needed a good source. Weave Got Maille will be that source from my first order forward. It's hard to find unanodized niobium jump rings but they have them and they are cut well and have no burrs. The jump rings anodized well and my earrings turned out great.
