Inspired by a charm from the 1960s, each Calendar pendant is completely custom made. Tell us the month, day and year of meaningful dates for you, and we will have it minted it in 10 karat gold and mark it with a diamond, or birthstone of your choice. A completely modern heirloom. Perfect for a mom or a grandma...the new "mommy" necklace. The month featured is the actual month from the specified year.
