brownamber

Brownamber is a color variant of amber, a fossilized tree resin used in jewelry and decorative objects. It denotes ambers with brown hues, ranging from honey-brown to dark chocolate, and these pieces can be transparent, translucent, or opaque. Brownamber is not a separate mineral; it is a form of amber whose color has developed through natural processes over time.

Formation and composition: Amber forms when resin from prehistoric trees hardens and preserves in sediment, undergoing polymerization over millions of years. Brown amber shares the same basic chemical basis as other ambers—primarily aged terpenoids and hydrocarbons. The brown coloration results from aging, oxidation, and impurities such as iron compounds or organic inclusions. Baltic amber is a well-known source of brown variants.

Appearance and inclusions: Brown amber can be translucent or opaque, with depth and warmth that can resemble cognac or chocolate tones in polished pieces. Inclusions of plant material or, less commonly, insects, may be present and contribute to value and interest.

Market and care: In jewelry, brown amber is valued for its warm, vintage look. Natural brown tones occur, and some pieces may be heat-treated to deepen or unify color; treated material should be disclosed. Common sources include the Baltic region and the Dominican Republic, among others. Amber is relatively soft and requires gentle handling.

Identification and authenticity: Tests include a resinous odor when heated, lightness relative to glass, and characteristic inclusions. Solvents can damage amber, so care is advised. Professional testing can help distinguish true amber from imitations.
