There is something so unique and pretty to use these beautiful agate rocks to personalize your special event. They come in all sorts of different sizes and shapes…they will go with just about any theme you may have for a wedding, reception, party, or special occasion. I found that at first, they are not that easy to write on in calligraphy. Using the proper ink and nib with them is key. I am using a Hiro nib and Dr. Ph Martin’s Bleed Proof White.
