All mood jewelry comes with a card explaining the meaning of the colors. A medium size color changing mood ring, made in 14kt gold or gold filled, you choose. Changes color just like the old ones! My rings are completely handmade by me. You won't find stones just glued into a pre-made setting here! Each ring is handmade with skill, attention and care, made to look beautiful and last for your lifetime! You may also notice my mood stones look a little different than others you may see around. I use a higher quality and more sensitive mood stone than what is commercially available. They are custom made for me, so you won't see them elsewhere! All my mood jewelry comes with a guarantee. If your ring stops working, I am happy to replace the stone for you, at any time. This ring can be used to stack with others or it can be worn by itself. Stone is 10mm. 14kt gold or gold filled. This is NOT plated gold. Please note, that mood stones do not like water. A quick, occasional wash of the hands will be fine, but please remember to remove before doing dishes, showering, swimming, etc. All mood jewelry comes packaged in a small box that is made of recycled paper and is recyclable! A soft velvet bag is also included to store your jewelry in. This will keep it safe and protect from tarnish.
