As with all things of nature no two are alike and sizes will vary. The one we send you will look similar but not exactly like the sample images we have provided. These candle holders have an average size of 3 - 5" long x 3 - 5" wide x 2 - 4" thick (approximate) and range from 1 - 4 lbs. These agate geodes have been cut for a flat bottom and polished face on one side (also known in the industry as PoF - Polished One Face) and really show the beautiful pattern of the stone on this side. A drilled center leaves room for a tea light candle that will light up the rock from the inside showing the pattern in through the polished face. Aside from the PoF the rest of the rock is in its unpolished form with unpolished edges that make them a nice natural piece. Of course when dealing with the element of fire please remember candles should never be left unattended and should only be used in the presence of an adult.
