Amber is found in a variety of places worldwide. It is fossilized tree sap (specifically from the pine tree, Pinus succinifera) and may contain dead insects or other debris. Sometimes, prehistoric insects increase the value of the amber. A great deal of amber has been subjected to different treatments to increase the clarity and improve marketability. Sun spangles is a term for round disc like visual inclusions in amber. This is from clarifying amber by heating in dry air or oil to remove natural air bubbles which give a cloudy appearance. If the treatment process is not done carefully, stress fractures or sun spangles will form. Therefore, if you see sun spangles, it is proof of some type of heat treatment to improve the clarity of the material.  

Amber is very light; therefore, large bead necklaces and other forms of jewelry can be made and still be comfortable to wear. Over the centuries it has been in and out of fashion. Be aware that copal (modern tree sap from the Dominican Republic and other places) is sometimes sold as amber. It can be distinguished from amber by a simple test: it softens rapidly in ether; amber doesn't. Keep in mind that plastics also mimic amber. They have an acrid odor when a hot point is used ( a burned plastic smell); amber has a resinous odor.

Although amber varies in color (mainly in the warm tones), it is recognized that the reddish brown color is considered the finest. Please be aware that amber can be dyed and often is. It is important to deal with a reputable source who will stand behind their product. Amber is not an expensive gem but one that has a long history in human affairs. It speaks to the ancient past of our earth and is a visible reminder of our connection to this planet. It is a wonderful, organic gem that ties us to the forces that have shaped our world and continue to influence our lives.
