December Birthstone: Turquoise Meaning, Color & Jewelry

The meaning of December's birthstone

Turquoise is one of the oldest gems in human history, set into the treasures of ancient Egypt, carried along the trade routes of Persia, and held sacred in the jewelry of the Navajo, Zuni, and other peoples of the American Southwest. Across all of these cultures it was seen as a sky stone and an amulet, worn for protection, healing, and good fortune, and given as a token of friendship. That long and shared history gives turquoise a warmth that few gems carry. As a December birthstone it brings that sense of protection and connection to a gift, a stone with deep roots.

The color of turquoise

Turquoise is a copper aluminum phosphate, and unlike most birthstones it is opaque rather than transparent, valued for its color and surface rather than its sparkle. Its hue runs from a pure, intense sky blue, driven by copper, through blue green to green as more iron enters the stone, and the clean robin's egg blue is the classic ideal. Many turquoise stones also show matrix, the veins and webbing of the host rock running through them; a fine, even spiderweb matrix is prized in its own right, so character here is not always a flaw. Because turquoise is soft and porous, most of it is stabilized with resin to harden the stone and protect its color, a common and accepted practice. For a closer look at color, matrix, and treatment, the guide to evaluating turquoise quality breaks it down.

Choosing turquoise jewelry

Choose the look you are drawn to, whether a clean, even sky blue or a stone with a striking web of matrix, since both are valued and the choice is largely personal. Turquoise is cut as cabochons, beads, and inlay rather than faceted, which suits its opaque beauty. It is well worth asking whether a stone is natural, stabilized, dyed, or reconstituted, because that affects both durability and value, and a reputable seller will tell you. For metal, sterling silver is the classic partner and the heart of Southwestern style, while yellow gold gives turquoise a richer, warmer frame.

Caring for turquoise jewelry

Turquoise is soft at 5 to 6 and porous, which makes it one of the more delicate gems to live with. It readily absorbs oils, lotions, perfume, and even sweat, all of which can darken or discolor a stone over time, so the simple rule is last on, first off. Never use an ultrasonic or steam cleaner or any chemical; instead wipe turquoise with a soft, dry or barely damp cloth. Keep it away from heat and from harder stones that could scratch it, and choose a protective setting for any turquoise worn in a ring. With that gentle care, turquoise keeps its color for generations. The fine jewelry care guide covers cleaning and storage for every stone and metal in more detail.
