Seventy-one percent of the earth is ocean. In this vast ocean, only 30 ° from the equator between the subtropical and tropical waters at depths of 200 to 200 m will the material exist. In addition, corals have a longer growth cycle: an inch in 20 years, a kilo in 300 years. Growing in the deep sea area, the technical requirements for excavation are relatively high imperceptibly increasing the difficulty of mining.

Although most of the coral jewelry we have ever seen is mainly red and pink corals. But, the most abundant coral is still white, however, the value is low, and generally will not be used to make jewelry. There are also very rare gold, black and blue corals. Why choose red coral to make jewelry, maybe the reason is the beautiful color or the high value! If you want to have a close view to appreciate corals up close, the coral museum will be a wonderful place. For instance, the underwater museum in Cancun, Mexico. The average person in this museum really can’t go there, first you have to be able to dive.

Coral is a biogenic gem. It is crystallized from calcium carbonate produced by corals, a Marine invertebrate. Therefore, the hardness of coral is low, very fragile, afraid of knock or touch. So be sure to keep it light, and not with hard stones!
The corals are actually the supporting skeletons left over from the dead corals. The ingredients are, of course, calcium carbonate, and contain a small amount of organic matter. So it’s afraid of acids and bases and all the other chemicals. Then stay away from cosmetics, perfumes and other chemicals! Now in the hot summer, corals are vulnerable to sweat, so remember to wash in time!

Since coral is an organic gemstone, if you don’t take care of it for a long time, the luster will certainly dim. However, you can use the negotiated colorless baby skin care oil or a little olive oil, a little soak or a wipe to try it, after a night can restore its original luster!
In fact, the more precious things are, the less resistant they are to stress. Of course, it also need to care carefully. In painstakingly upkeep, the gems glow. This is not the affirmation of the gem, but also the affirmation of their own efforts.
