This is a vintage Unmarked 4-sided obelisk, pyramid, monument. It is approximately 11 3/4" tall and 2" x 2" at the base. It tapers to the top. The pattern or design reminds me of fern leaves and I called it "Ferns". Each flat side has a groove cut in the center running from top to bottom. The frosted fern leaves run off of both sides of the groove, The corner edges and base edges are beveled. The frosted fern leaves extend into the beveled edges in places. I purchased this in the late 1970s or the 1980s from the 5th Avenue NYC Tiffany Co. store. This obelisk is not marked. At that time, Tiffany's 5th Avenue store sold obelisks manufactured by many companies including Baccarat. Some were marked, some were not. I lived in NYC before moving back to Denver. I started collecting obelisks and displayed them on a silver mirrored tray. It reminded me of a city skyline. I looked this obelisk over with a magnifying glass and felt it by hand. I found one very small "flea-bite" on one edge. See Last Photo. There are several very small bubbles in the crystal. I am downsizing and am selling most everything. Non-smoking household.
