I have Raynaud’s Syndrome, therefore my hands are almost always a different color - typically red and/or purple! So you may notice variations in the pictures, not because I’m applying filters, but because that’s how strange this condition is! Only sharing to help explain differences you may see throughout my listings) Please see pictures for additional details AND ………Check out my closet to see more beautiful, genuine & unique jewelry and save with a bundle! (always open to offers) Thank you for looking 💖 Disclaimer: Color may vary slightly due to viewing device, monitor settings and/or lighting conditions at time of photographs. I do my best to capture everything accurately 😊 Please ask questions if unsure!
