Brazilian Agate is unique in color and exhibits natural marbling. Some even have crystals that may go all the way through! These "holes" are not considered damage and are a beautiful part of the natural stone. If you do not want any crystal openings in your coaster, please leave a note at checkout to guarantee this. The edges of each piece can be electroplated (not gold leaf or gilded, which may rub off) with beautiful thick metallic GOLD or SILVER. Also available for purchase with no plating so edges will be left natural and raw. Each coaster comes with small, clear rubber feet on the bottoms to keep the agate slices from sliding or scratching surfaces. You will receive a SIMILAR set as in the photos. ► Green agate coasters are a lovely green that ranges from forest green to olive green. For the most part these are evenly colored. Some inclusions may be present around the edges. ► Size: These slices will vary in size from approximately 3.5"- 4" long by 3"- 4”wide and 1⁄4” thick. They are the perfect size for drinking glasses or mugs. ► Free gift wrapping - your coasters will arrive tied with beautiful ribbon, and shipped with plenty of wrapping to protect them in their travels. They come ready to gift to yourself or a friend!
