The photos contained on this page are representative of the gems that are available. No two gemstones are alike. Most rectangular pieces are approximately 1” x 1 ½”. You will have the opportunity to describe the shape and size you want in the comments section of your final order page*. You may specify an assortment of shapes if you would like. Unless what you are ordering is difficult or costly to make, such as precision cut teardrop shapes or circles where there is a lot of glass waste and extra prep time, there is no extra charge for different sizes or shapes.
