Did you have another child, grandchild, adopt? You can add an individual crystal to your necklace. Choose the length of the drop by choosing the corresponding number from the diagram and then choose the month.
There are 2 different crystal sizes to choose from. Most necklaces I make use the "regular size 6mm size crystal. However, if you have a necklace with 8 or more birthstones I use the "smaller size 4mm size crystal for those necklaces. If you have any questions please contact me!
