Bronze ring bars
This adjustable bar ring is an ideal gift for those who love math or a modern, minimalist design.
The ring is adjustable from size 6, in this size it is quasi closed.
We recommend setting the ring to the desired size and from then on limiting opening/closing to the maximum. Frequent opening and closing can lead to faster wear and cracking.
I do not have a (similar) ring to determine my size
Measure your finger with a string to determine the ring size. For a wide ring, take one size larger, as it will not only go into the crease of your finger but also above it. (Rings may vary from the size chart by a few tenths of a mm).
| circumference inside (in mm) | inner diameter (in mm) | |
| Size 5 | 48.8 | 15.4 |
| Size 6 | 52 | 16.5 |
| Size 7 | 54.5 | 17.3 |
| Size 8 | 57 | 18 |
| Size 9 | 59.8 | 18.9 |

Like silver, bronze will eventually oxidize, although most of our bronze jewellery contain a ceramic coating to prevent/delay oxidation. Bronze that oxidizes becomes darker in color which gives the metal a beautiful, somewhat antique touch. Normally the darkening happens evenly, but cosmetics or chemicals can cause different (or even green) effects. Water and (hand) soap are not a problem.
When your bronze darkens, you can wipe it clean with a flannel cloth, possibly with a damp cloth with a little ecological detergent. After that, dry your jewelry thoroughly.
In some people, a bronze ring can leave a green-black shine; this is harmless and can be washed away. If you want to avoid this, it is advisable to keep the ring as dry as possible and possibly occasionally go over the inside of the ring with the abrasive side of a scouring pad.
Nina Designs is a jewelry brand with a heart of gold that makes fair trade jewelry in Thailand and Bali and tries to be as ethical and ecological as possible. Their wages are well above the national minimum wages, employees receive a thirteenth month, 3 months paid maternity leave, education on pre- and post-natal care, retirement savings, etc. In their studio in Bali, 50% of the managers are women, which is even more impressive there than here.
Nina Designs uses as much recycled silver as possible in its production in Bali and only recycled silver in its production in Thailand. A tree is planted per package shipped, which is part of a so-called "forest garden." The jeweler gives microloans to start-up craftswomen and supports various NGOs fighting for human rights, literacy or the environment. And, of course, their silversmiths make beautiful jewellery!
