This is an interesting candle holder, a glass box octahedron made of beveled glass triangle panels. I have also seen this type of item called a terrarium. The base is mirrored, the top is open. It holds a small glass cup for a votive size candle. The piece is 5 1/4" wide and 4 1/4" tall. It is in excellent condition with no chips or cracks. It is not signed or marked in any way. MBR.
