These adorable Valentine/Gift Cards are the size of a standard business card printed on a matte, textured paper and feature our 20mm crystal hearts. You will receive a RANDOM ASSORTMENT of the following stones: Green Aventurine, Obsidian, Rose Quartz, Rhodonite, and Tiger's Eye. We will do our best to randomize your order and get you a good assortment of each stone type. The hearts are attached with a small dot of hot glue, which easily removes from the stone. It is very possible the glue may come unattached during shipping! You can simply reattach with hot glue, poster tack, or double sided tape. We apologize if your stones detach from their cards in transit, but we don't want to use any stronger of an adhesive and damage the stones. NOTE: Stones are natural and WILL vary in exact color and pattern.
