The birthstones for December are turquoise and lapis lazuli.

First of all, turquoise is a gemstone characterized by its bright blue color. Turquoise is a copper and aluminum phosphate mineral found in underground deposits and sedimentary rocks. Blue turquoise is colored by impurities such as iron and copper.

Turquoise has been known to exist since ancient times and has been considered a sacred stone in many cultures. It is particularly important in Southwestern American and Middle Eastern cultures, where it has been used in religious ceremonies and ornaments.

Turquoise is considered a symbol of protection and good luck due to its calm and warm color. It is also considered a stone of healing and peace, and wearing it is said to bring peace of mind and promote creativity.

Lapis lazuli is a gemstone known for its bright blue color and golden flecks. Lapis lazuli is a type of mineral crystal or rock, and its main component is a mineral called lazurite. The blue color is mainly caused by the lazurite component, and the gold spots are formed by the pyrite it contains.

Lapis lazuli has been known to exist since ancient times, and was particularly important in Egyptian and Mesopotamian cultures. In ancient Egypt, it was considered a sacred stone, used in the tombs of the pharaohs and in jewelry.

Lapis lazuli is a stone that symbolizes nobility and harmony. It is also said to enhance insight and intuition, and support creativity and spiritual growth.

Lapis lazuli is characterized by its beautiful blue color and spots, but natural lapis lazuli is a relatively soft gemstone, so care must be taken when handling it. Proper care and protection is required when used as jewelry.
