In addition to being beautiful, symbolic, and interesting, some couples choose black wedding rings as a practical necessity. Many people work in jobs that use manual labor such as construction and manufacturing. These professions use tools and machinery that could scratch metal bands and crush even the hardest gemstones.
It would be sad to forego wearing a symbol of love because of practicality while on the job, but many people are forced to do this. However, durable black metal or rings are growing in popularity because of their hardness and strength.
These rings can be worn in all sorts of conditions without breaking, which can provide peace of mind to the wearer.
