Herkimer diamonds will vary in size and shape as will the pyrite stones. Please make sure to specify what size you would like. These are made to order and may take 2-3 weeks to complete. Please note that no two pieces are the same, and any jewelry pictured may differ slightly from what you will receive, especially those containing raw stones. Texture is normal. Raw stones come in many different shapes and sizes, so they will differ from those shown in the listing. Colors may be different in person than on your computer screen. I make all of my copper jewelry with a process called electro forming. Please keep in mind ring sizes may not be exact (but very close) depending on how thick and even the copper deposits onto the band, and small imperfections are normal. All copper is sealed to prevent discoloration from oxidization. I highly recommend purchasing a sealant like Protectaclear as the copper will need to be resealed every once in awhile. Avoid contact with heat, harsh chemicals, and abrasive materials. Avoid wearing in water and keep away from oils, perfumes, etc. Avoid bending or dropping pieces as the stones may get damaged. I will include care instructions with every order! Check out our FAQ's section!
