Zirconium is harder than Platinum. ZiRO rings are crafted from the mineral Zircon which is found in S-type giant stars and the sun. The rings are created through a heat-treating process where they are exposed to extreme heat. Zirconium forms a strong black oxidised coating which feels similar to ceramic in texture.
ZiRO rings are comfortable, durable, hypoallergenic and available in a range of unique and classic styles.
