The sea stone, the scientific name of blue amphibole, also known as "Lalima Stone", is the national island of the Caribbean island country, Dominican Republic. In the foreign market, the collection heat is relatively high, but in the country it is a rare special, its appearance is considered to be Tianhe stone, especially made of small pieces such as beads pendants.
The sea stone, stone as its name, has a sea-like blue color, and a blue-green color with a white sea wave. Under the action of light, it has the geometric beauty of plaque plaid.
Sea stones, indigenous Indians on the Caribbean islands have long discovered and used this gem called Larimar. The production area is located on a Caribbean Mountain in the Dominican region. The effective mining area is only about 15 square kilometers in size, and the minerals are produced in the gaps or holes in the volcanic rocks in the area. Therefore, the mining of minerals must be done by manpower. When the tools are mined, it is obvious that these ores are quite precious and rare.
The inner phase of the sea shale contains copper, which is a kind of towed amphibole. It is opaque sky blue or volcanic blue. It is green or green. If it is watery, it is a distinct feature, sometimes With red to brown (iron-containing ingredients) or gray inclusions, its luster, color and increasingly scarce production make it a place in the semi-precious stone market. The cause of the blue sky of larimar may be the result of traces of copper, vanadium or light scattering in the mineral itself.
Since the hardness is 4.5-6, the specific gravity is 2.7-2.9, so it is soluble in hydrochloric acid, and should avoid the acid sweat from eroding for a long time.
