These Valentine/Gift Cards are the size of standard business cards printed on matte, textured paper and feature our 20mm crystal hearts. You will receive a RANDOM SELECTION of the following: Green Aventurine, Obsidian, Rose Quartz, Rhodonite, Quartz, Dalmatian Jasper, Dragons Blood Jasper, Green Opal, Labradorite, Red Jasper, Ruby Zoisite, Sodalite, Unakite Jasper, & Tigers Eye. We will randomize your order and get you a good assortment of the stone types, but cannot guarantee any specific quantities. The stones are attached w/ a small glue dot, which should easily remove from the stone. Any remaining sticky adhesive can be removed with rubbing alcohol. It is 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 stronger adhesive and damage the stones. NOTE: Stones are natural and WILL vary in exact color and pattern.
