This sun and moon matching necklace set is perfect as a gift for couples, sisters, siblings, and best friends. The charms are etched from reclaimed silver and polished to a beautiful shine. Because I use reclaimed silver to create each piece, there may be slight variations in the texture of the silver, giving each charm an organic and rustic look. I then add a patina to darken the recessed area of the charm to ensure the sun and moon stand out, then I polish again. Each set of necklaces comes with your choice of the stainless steel rolo chain adjustable between 18" and 20" and/or sterling silver chain adjustable between 16", 18" and 20". Please feel free to message me with questions, I typically respond very quickly. Please check the listing description for the processing speed, under the "shipping" section of the description. Because my designs are very minimalistic, I don't add the .925 mark to my sterling silver pieces, but I do guarantee the quality and silver content.
