This tea light holder is made from hand poured and sculpted cement. Makers Tal & Bert use a hollow breakage in the design to create a geode from raw natural flourite stones that they mined in Mexico. They then edge the geode area in liquid gold to create this stunning look. Geode shape and size will slightly vary from holder to holder but each is about 2.5" wide x 1.5" tall. Each one comes with an unscented tealight candle.
RIP at end of life your best bet is to befriend an artist to upcycle the pieces.
