If you have a question that is not listed, please contact me and I’ll be happy to assist.

Occasionally after a trade show there may be few items in stock but mainly all products are made to order to ensure they leave the workshop in perfect condition. So take the manufacturing time into consideration when buying items to be handed over as a gift.

Items not on hand at time of order will ship approximately 4 weeks after the receipt of your order. You will receive confirmation of shipment when the order is sent. If you need your jewellery sooner, please contact me to see how quickly I can accommodate you.

Ujo ring sizes are equal to the inner diameter of the ring in millimeters. Choosing the right ring size will take a bit of effort and time, but it is important to get the size right – too tight a ring is uncomfortable or impossible to wear and too big a ring will easily slip off from the finger. The size of the finger changes, even within the same day. They will also swell in warmer weather and vice-versa in cold weather. Keeping this in mind; you should check your ring size more than once which applies to both a simple home check or even a proper sizing in-store with a jeweller.

If you want to try to check it at home with a piece of paper, curl it around the finger and use a pen to mark the spot where the paper ring feels comfortable. The length of the straightened shred will give you the circumference of the ring and the correct ring size can then be found from the conversion chart. Wide rings require a bigger size than narrow rings. If you are measuring your finger with a strip of paper, use the correct ring width as well.

If you already have a ring that fits perfectly, you can measure the inner diameter of the ring. The most accurate tool for that is a digital caliper, but if that is not available, print out this sizing tool and see if you can find the right size. Also note that older rings may no longer be perfectly round and the measurement may be slightly incorrect.

Sterling silver is an alloyed metal. It is 92,5% pure silver with 7,5% copper added. Sterling silver is a popular metal because it is affordable and malleable, but it also tarnishes quickly because of its composition. Therefore many of my silver products are also rhodium plated (mentioned in the product description) to prevent them from tarnishing and to keep them shiny just a bit longer.

No. I get my materials from a reputable Nordic retailer, K.A. Rasmussen, all their material is nickel free.

However, some of the coin rings are copper/nickel alloys, so make sure you are not allergic before purchasing, or choose bronze or silver coin rings instead.

As long as the altered coin is not being used with the intent to commit fraud (trying to use the coins as legal tender after being altered), then it is perfectly legal. Changing the entire shape of the coin by forging it into a ring is now a piece of jewelry. More information.

All my jewellery (my own collection and custom orders) are either solid silver or gold and contain my hallmark and metal hallmarks.

What is Photoluminescence?
Photoluminescent materials (commonly called “glow-in-the-dark”) can absorb and store direct light energy (sunlight, fluorescent, incandescent, etc.) and upon removal of the light source, the stored light is gradually released – the strongest glow is produced during the first 30 minutes of darkness, the most critical period following a power failure or other emergency. The glow can last from a few hours to several days depending on the quality and color. It then fades over a period until reintroduced to a direct light source, so it may start the process again. The pigment can repeatedly absorb energy and emit visible light for over 20 years without any perceivable change of its properties.

Is it environmentally friendly?
Photo luminescent materials are non-toxic, non-radioactive and contain no phosphorus, lead, or any other hazardous chemicals.

More information about the pigment and the colours I use.

Can they be used instead of a reflector?
Although they have a bright glow, it may not be visible from far away in traffic. Stay safe at night, always wear a reflector.

All items from Ujo webshop include a polishing cloth to keep them looking good in the future as well. Items are best stored in a small resealable bag since they sometimes tarnish even while being in their boxes. As a general rule, it is best to always put your jewellery on last, because hair products, perfume and cosmetics will accelerate tarnishing. Also remove your jewellery before swimming, working out, cleaning and sunbathing to keep them looking brilliant for years to come.

How do I clean my jewellery?
If they are dirty, use an old, soft toothbrush with warm/hot soapy water to clean them. Don’t use toothpaste, it’s abrasive and will damage your jewellery.

What causes tarnishing?
Tarnishing (oxidation) is a result of oxygen or sulfur coming into contact with sterling silver. The air especially here in Oulu is known to be highly sulfuric and silver will tarnish if not kept in an air-tight bag for storage. To clean any tarnishing, use a polishing cloth to regain a silver finish. Some of my designs are intentionally oxidised to highlight certain details on a piece of jewellery, so avoid those areas when using a polishing cloth.

All white gold is essentially an alloy of pure (24ct) yellow gold, so it is natural to assume that it has a yellow tinge. Rhodium plating is a process which gives the white gold its ultra white colour by placing a coating over the existing metal. Rhodium plating should last at least a year. The more you wear it, the sooner you’ll start to see the gold colour coming through.

How much does rhodium plating cost?
The ring must be buffed and polished before it can be plated, so depending on the wear and tear, the cost is typically around 60 euros. I can rhodium plate rings whether or not they were purchased from me.

As with any bespoke manufacturing company, I am unable to have fixed prices on custom order products. As every piece is made to order to the customer’s specifications, prices are calculated on a one-to-one basis according to precious metal prices and the stones used.
