Custom made by Jenna Hardie, she starts out with a black ceramic ring, then carefully adds White Opal stone, Copper shavings and a blue powder that has a bright aqua glow when activated by a UV source such as a blacklight or the sun. Ceramic is extremely durable, scratch resistant and comfortable! Since these are custom made, no two rings will look exactly alike! It is HIGHLY recommended that you do not engage in strenuous activity while wearing your ring especially anything that will directly impact it. This will keep your ring lasting much longer!
