The "Tundra" ring is hand made by artisan Jenna Hardie. A White Pearlescent pigment with copper shavings, Periwinkle Opal and crushed Amethyst really makes this ring stand out! All of this is reinforced with a strong black ceramic ring for durability and comfort! 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!
