Each necklace is unique. Chain may vary slightly from photo. I recommend you go with the 30" long length chain because of the size of the pendant and the added glitter ball family member beads. If you would like a short chain I would recommend the small tree pendant (even then I prefer the long).
Please specify in the notes, before paying, the MONTHS you need on the necklace. Please list as many months as you did family members, for example if you pick 5, then in the notes list five months such as: Jan, April, April, July, October
