Amber is fossil resin, which is appreciated for its color and beauty. Good quality amber is used for the manufacture of ornamental objects and jewelry. A common misconception is that Amber is made of tree sap; it is not. Sap is the fluid that circulates through a plant's vascular system, while resin is the semi-solid amorphous organic substance secreted in pockets and canals through epithelial cells of the plant.

Most of the world's amber is in the range of 30–90 million years old. Because it used to be soft and sticky tree resin, amber can sometimes contain insects and even small vertebrates.  Amber occurs in a range of different colors. As well as the usual yellowy-orange that is associated with the color "amber", amber itself can range from whitish through a pale lemon yellow to brown and almost black. There is also red amber (sometimes known as "cherry amber"), green amber, and even blue amber, which is rare and highly sought after.

Larimar is a rare blue variety of pectolite found only in the Dominican Republic, in the Caribbean. Its coloration varies from white, light-blue, green-blue to deep blue. The deep blue variant is known as volcanic blue. Although pectolite is found in many locations, none have the unique volcanic blue coloration of larimar. This blue color, distinct from that of other pectolites, is the result of cobalt substitution for calcium.
