Mokume Gane 14K Palladium White Gold White Montana Sapphire ‘Riparius’ Ring

I designed and created the ‘Riparius’ ring inspired by the erosion and deposition of rivers over time. The 14K palladium white gold and sterling silver mokumé gane ring features a rare white Montana sapphire, 0.52 carat, 5.5mm x 5.2mm. I hand-fabericated and set the pentagonal sapphire in a 14kt Palladium white gold bezel. The ring also includes recycled 14kt white gold granulation and (2) 1.5mm, .04ctw lilac spinel, (1) 2.3mm, .05ct blue Montana sapphire round accents.  The ring is made from three different strands of 24-layer 14kt Palladium white gold and oxidized sterling silver Mokume Gane. Size ‘5.75’ is available.

The ring measures approximately 10.5mm at its widest and 5mm deep at the top center stone The strands are between 1mm to 2mm wide and approximately 1.8mm thick. The sparkly white sapphire has striking clarity for a Montana sapphire and I would rate it around an SI1 clarity.

*This ring can be sized down to a size ‘4.5’ and up to a size ‘8’ at the high end. 

Just let me know what size you need in the ‘notes’ section during checkout.

(The Montana sapphire is from the Spokane Bar, mined in 2018 by me and Sarah. I faceted it in 2019 in a modified Step Five pentagon design by Walt Heitland)

      Caring for Your Jewelry



      To prolong the life of your fine jewelry and protect it from damage, we recommend the following care:

      Activities to Avoid While Wearing Your Jewelry:

      The following activities will expedite the speed of oxidation of your jewelry, and potentially cause damage, especially to stones. Therefore, it is recommended that you do not wear your jewelry while:

      • Swimming;
      • Using cleaning chemicals;
      • Applying lotions and perfumes;
      • Lifting heavy objects (e.g. lifting free weights, carrying metal furniture, yard work, etc.);
      • Washing dishes;
      • Engaging in any activity that results in a sustained amount of time in water;
      • Engaging in any activity with potential damage to the hands, such as rock climbing, auto repair, construction, etc.

      Recommended Cleaning of Your Jewelry:

      • Use a mild, non-abrasive soap and warm water.
      • For particularly dirty jewelry, gently clean using a soft toothbrush with mild soap and water.
      • You can remove tarnish from silver on the inside of a ring with a silver or general jewelry polishing cloth. (NOTE: if you use a polishing cloth on the patterned Mokumé surfaces, the polish may temporarily make the pattern difficult to see. The pattern should return as the metals oxidize in reaction to the environment.)
      • If a polished stone inlay has become dull, you may want to return it to us for re-finishing.
    • Ring Fitting

      Ring Fitting

      We highly recommend visiting at least two to three reputable jewelers to have your finger sized. They should use standard fit sizers, and they should agree on the size. It is also important to tell the jewelers how wide your ring will be since width is a determining factor in sizing.

      Meteorite rings and rings with inlay cannot be re-sized.
