December Birthstone Color


Tanzanite is a calcium aluminum silicate with prismatic crystals that come in a number of colors, blue, purple, green, yellow, brown, lavender and pink . It is a hard mineral and is fairly dense with a high refractive index. It is said to have mystical powers. It has a vitreous luster and is transparent.


Zircon is zirconium silicate and is used in industry as well as jewelry. I used zircon when developing high temperature ceramics years a go. The colors are light brown to reddish brown, grayish, yellowish, reddish, green and not blue. It is hard and dense with luster.


Turquoise is a copper aluminum phosphate coming in sky blue (most desirable as a gemstone), blue, blue green, yellowish green, often with brown, black or metallic. It is fairly hard. Luster is waxy or sub-vitreous.

Having lived in Arizona and Utah, I have always like turquoise. You can find it on certain sites in the western states.

What ever you choose in a December birthstone, you will have a wide selection of jewelry.

My little brother, now 79 years old (today) was born in December. I guess I could buy him a turquoise bolo. The day he was born was the day I realized how poor we were during the Great Depression.

Happy Birthday!
