charm bracelets TheFire Tree”, one of the Seven Treasures of Buddhism-Coral

Coral grows in a specific sea environment. The dendritic aggregate formed by the calcium secreted by coral insects is called thefire tree”. It is listed as the Seven Treasures of Buddhism alongside gold, plata, perla, ágata, amber and colored glaze. Entre ellos, red coral is the most precious, regarded as a treasure in the sea, the best in the hidden. Coral is one of the important raw materials for arts and crafts carving, and it is also a medicinal material for traditional Chinese medicine.

Coral is brittle, foams strongly when exposed to hydrochloric acid, without fluorescence. The colors are blue, rojo, rosa, naranja, and white, among which red and pink are the most popular, and black horny corals are rare. The red color is formed when corals absorb about 1% of the iron oxide in the seawater during the growth process, and the black color is due to organic matter.

Color and blockiness are the basis for coral evaluation. Colored ones have higher quality than white ones, and the colors are beautiful, bright and pure. Red coral is the most precious. The larger the coral block, Cuanto mejor. The value of coral is also influenced by the customs of various places. Por ejemplo, the Arabs prefer bright red, while pink is popular in Europe.

Calcium carbonate coral has a dendritic structure, with small holes on the surface, and a radial cross-section. When cut into small round beads or semi-round beads, the branch structure can be seen. Reacting with dilute hydrochloric acid can produce a lot of bubbles.
