Small fits wrists 5.5"- 6.5", medium - 6.5" - 7.5", large - 7.5" - 8.'. Measure around the part of your wrist where you would wear it.
Two layers of trees, positive and negative, light and shadow, like a forest in winter, or the shadows under the canopy. Some photos show a light patina added to the inside of the silver cuff to bring out the layers. If this is something you would like, it is available through my etsy shop.https://www.etsy.com/shop/DeborahLaun
