Jewelry Gift Ideas Part 2: December Birthstones

There is so much to love about December. The winter solstice, holidays, and the opportunity to spend time with family and friends. The wonder of the season also extends to those with December birthdays, as it possesses three fascinating birthstones: Tanzanite, turquoise, and blue zircon.

Renowned for their alluring shades of blue, these birthstones make excellent gifts, no matter who you’re shopping for this holiday season. You can also consult a local jewelry store to custom design a piece with the birthstones of your children or siblings that the recipient is sure to cherish forever.

December Birthstones

Tanzanite Birthstone

Tanzanite is a relatively new gemstone that is composed of the mineral zoisite. According to the American Gem Trade Association, tanzanite was not discovered until after a wildfire engulfed Tanzania’s Merelani Hills at the base of Mount Kilimanjaro in 1967. The gem has since been treasured for its mesmerizing blue to vibrant purple color.

With a hardness rating of six to seven on the Mohs Hardness Scale, tanzanite is ideal for a variety of jewelry pieces, including earrings and necklaces. Aside from being one of three December gemstones, tanzanite makes a spectacular 24th wedding anniversary present, as well as a stunning holiday gift that the receiver will love.

Turquoise Birthstone

Regarded as a love charm, according to The Old Farmer’s Almanac, turquoise is a luxe gemstone that ranges in shades of blue to green. The gem may also exhibit other colors/hues, such as gray or black, which lends to the stone’s unique look. Its color is frequently characterized as “Robin’s Egg” or “Sky Blue.”

According to the Gemological Institute of America (GIA), the most intense blue turquoise production comes from Kingman, Arizona. Turquoise has a Mohs hardness of five to six and can be custom designed in your choice of jewelry type. The birthstone can be set as either a center or accent stone. The latter is shown above.

Blue Zircon Birthstone

While zircons are available in a rainbow of colors, blue zircons are undoubtedly the most popular, especially as a December birthstone. According to GIA, “gem dealer reports indicate that at least 80 percent of zircons sold are blue.” Blue zircons can even be found as antiques originating from the Victorian era.

The December birthstone has a Mohs hardness of six to seven and a half and can be set in various jewelry pieces, like rings and bracelets. As with tanzanite and turquoise, blue zircon makes an excellent holiday gift, even if the recipient isn’t celebrating a birthday in December.
