This is a lovely Fenton Guardian Angel Figurine in Irridized Crystal. It looks as if the robe might be satinized but I can't tell for sure because of the irridization. Her wings are absolutely loaded with frit giving them a feathery look and texture.
She is marked although you can't see it because of all of the frit on her wings. However she does have her original label on the bottom indicating her ware # 5533 WY.
Fenton introduced the Guardian Angel figurine in 1994. This lovely lady was produced in 1995 as part of the Heavenly Angels series and was only available through the Christmas Supplement. Which is where I found her listed.
She measures just 3 1/2" tall and is just a shade over 2 1/2" across the base. She is in excellent condition with no chips, cracks or nicks. There is no wear and she has no repairs.
She'd make a great christening gift for that new baby.
