The Moon stone set within the qualified 925 sterling silver is a beautiful piece. I love that the stone has a small inclusion that shows tones of Indigo and purple deep within its heart. I appreciated Rising Moon Minerals knowledgable staff and the high quality pieces within its small store front. I did not get overwhelmed by options instead understood that each piece within the store had been carefully crafted by hand, or selected for resale with great consideration for authentic quality. Thank you! I will definitely be back!
