Heart Locket Ring,Sterling,Etched,Vint,Sgnd,Beautiful!

Unusual vintage sterling silver,etched heart locket ring. Finger size 7. Has a nice thick band. When the locket is opened, it is deep enough to put things other than photos in it. Similar to a poison ring. No suggestions intended. The heart locket itself measures 3/4 x 7/8 x 3/8 inch high. Sits securely on band. Hinge and locking work perfectly. Looks like it was never used. Beautiful etching all over heart. The band is marked NF925. I do not know who NF is. Excellent condition. I do not think it has ever been worn. Shipping is $2.50 for 1st class,delivery confirmation. Enjoy!
