This is a set of 2 gorgeous Mid Century Crystal Bohemian Czech Crystal Candle Holders by Elements in Block Glass. They have 6 sides (hexagon) with 2 square blocks on each side with an indented circle.

Pre-owned excellent vintage condition.

Large, heavy solid glass Candle Holders (could be used as small vases or plant holders also), marked "Elements", "Made in Czech Republic". 

Size: each holder is about 5 inches tall, 3.5 inches wide, and weighs over a pound.

Mid-century Bauhaus / Bohemian Czech art glass made by Elements in the 1960s/70s.

I also have a matching glass vase available (see listing or message me for details).
