Early Melanie Guernsey hand blown jar

Found this at a local Goodwill. Signature on bottom reds M. Guernsey. Found an established glass artist named Melanie Guernsey-Leffler who graduated from a local college(RIT) in 1986. This piece is engraved 84, so I assume it is one of her early student pieces. What caught my eye was the slightly off balance shape and the polished bottom.
