This is fantastic! I just received the greatest Christmas present from a friend, the lovely Sue from Lily and the Weasel. The Hypnum cupressiforme faux ring is from a fabulous company called adornjewelry. The blurb that comes with the ring is particularly fabulous - Proper lighting and watering are usually the most important criteria for the health of a plant. When it comes to your faux moss jewelry, this extra care is not necessary. Clear instructions and a spare piece of faux moss in case anything goes wrong, what more could you want in an accessory?
You can grab one of these rings on the adornjewelry etsy shop.
