Arn Krebs Shop Policies and FAQ

Thank you for your interest in my jewelry! Arn Krebs Arts is a one-man studio that specializes in custom-made mokume gane wedding rings.

Mokume gane is an ancient metalworking technique in which layers of precious metal are alloyed together with heat and pressure, then twisted, carved, and forged to create beautiful organic patterns. My mokume patterns are made in various combinations of yellow gold, red gold, silver, and palladium. In my many years of making mokume I’ve developed the skillset to make bands that resemble wood grain, topographical canyons, oceanic waves, and other natural formations. I take pride in the custom nature of the work and offer the widest selection of mokume patterns that you will see at any shop.

All mokume rings are available in any size, width, profile, pattern, metal combination and finish. Select a stone from our inventory, have us find something special, or provide your own stone for setting. All rings are made individually from start to finish and so will be completely custom. Please note that all mokume patterns are unique and so will vary slightly from those pictured.

Payment Policy

For all custom work we require a half down deposit before beginning production. The remaining balance is due upon the shipment of your order. Should you prefer smaller incremental payments let us know and we will work with you to set up a plan that accommodates your needs. 

All of our listings are priced based on the cost of the band and do not include the cost of stones. We are happy to find gemstones for you, or to use yours in a custom creation. We ask for a 20% finders fee on all stones valued at $500 or more. Should you prefer to provide your own stones, Arn Krebs Arts will not be responsible for their quality. Upon receiving your stone I will assess it's quality and inform you of any risk and liability issues that I foresee if it is used.

Shipping Policy

Please allow 3–4 days for your order to be processed. Custom orders require a production time of 4-6 weeks. Please inform me upon ordering if you need your ring for a specific date so I can work with you to meet your needs.

All shipping costs are the responsibility of the buyer and include the cost of insurance. The fee for shipping within the US is $35.00 per item.

Refund Policy

Due to the custom nature of the work we are unable to offer refunds. Should you be unsatisfied with your purchase we are more than willing to alter the item to your liking. Please notify us before returning an item so we can work with you to make sure all alterations meet your needs. We are proud of the integrity of our work and have never had an unsatisfied customer.

My Mokume rings are heirloom quality and will wear as well as any solid gold ring. Years of experience using solid state diffusion bonding and the use of specialized aerospace material compression blocks make my billet lamination top quality, providing a material as strong as any solid metal.

Customization Options:


I specialize in mokume patterns and can offer a wide selection of patterning options. The pattern descriptions are meant to give a general idea of the look of the ring, but please keep in mind that every item is individually made by hand and will inevitably vary from other rings in the same pattern category.

All mokume patterns are achieved by one of two processes; carving or forging. Guri Bori mokume requires the most involved carving, resulting in a ring that has recesses or layers that resemble topography. Other carved patterns include the wood grain pattern, the twist pattern, and the droplet patterning. Forged patterns include end grain pattern, wave pattern, flow pattern, bookmatched endgrain, as well as others.

Please note that all mokume patterns are unique and so will vary from those pictured. The images in the listings are meant to give a general idea of the look of the ring, but please keep in mind that every item is individually made by hand and will inevitably vary from other rings in the same pattern category.

All of my metal is responsibly sourced. I use 14k yellow gold, 14k red gold, sterling silver, and palladium. My mokume involves any combination of these metals, as the listings will picture. I prefer using palladium over white gold, as the two are indistinguishable visually and palladium has far better wear characteristics.

All mokume rings are available in an etched or satin finish.

Etched rings containing silver can also have an oxidized finish that turns the silver a dark gray/black hue. Please note that although the oxidization treatment is stable and durable the black color of oxidized silver is a surface treatment and can be worn off or degraded by some chemicals. Your own body chemistry and lifestyle will affect the lifespan of the treatment.

I only oxidize rings that have been etched as this provides protection from wear as the silver layers are recessed. In my experience this technique can last years and I am always happy to re oxidize your ring any time.


All my rings can be made in any width. I recommend that you fit a strip of paper around your finger in various widths in order to get a sense of what width suits your hand and taste.

Please note that the mokume patterns shown in our listings will vary depending on your ring size and the width of the ring. In order to maintain the proportions of the pattern, a larger ring size would call for a wider band, and a smaller ring size would call for a thinner band.


Other available customizations include tapering, lining the interior of the ring in a layer of a single metal, and adding railings to the ring that frame the mokume pattern.

I am happy to work with you to achieve whatever other ideas you have for your custom piece. If you don’t see the characteristic you’d like pictured, do not hesitate to ask if it’s something I can do.


Upon receiving your deposit I will mail you a set of ring sizers that correspond to the sizing scale I use in studio. The sizers are in full and half sizes but all of my rings can be made to quarter sizes as well. I ask that you measure your finger at different times of the day throughout a span of 2-3 days. The average of several measurements should be the most accurate ring size for you.

I make every effort to get ring size correct first time, but fingers fluctuate size throughout the day and season, so sometimes rings do not fit perfectly out of the box. I recommend wearing the ring a bit as it may actually fit correctly. If it is not the right size I will resize the ring for free with the customer paying shipping to me and I will pay return shipping. If more sizing is needed the customer pays shipping both ways.

All of our bands can be sized both up and down a full size without any change in pattern. Sizing rings beyond one size may require the addition or subtraction of material which could effect the pattern.
