The three birthstones associated with December are Tanzanite, Zircon, and Turquoise. This tone of colors were strongly favored as a popular gem in Victorian jewelry. Our December Birthstone Collection is designed with a variety of blue hues in numerous faceted shapes. Being that there is not 1 true color blue that is the standard for the birthstone, you will find an amazing array of color in each of the unique pieces of jewelry in this collection. We also welcome inquiries for larger style pieces of jewelry including necklaces, hair pieces and bracelets which have the same concept as the rest of the December Birthstone Collection.
