This 1 pound stone has a delicate edge of Petoskey hexagons which fades into a sea of crinoids. The stone is 5” in length x 4.25” wide x .75” high. Each Oil Lamp has a floating effect with the stone resting on a sleek glass base. This stone has a smaller base which will allow a burn time of 4-6 hours depending on how tall you keep the 4” wick while burning. Each lamp comes with 4 ounces of a smokeless, orderless paraffin oil and instructions on care/use of the lamp.
