I. Characteristics and identification of aka and sardines of red coral
Red coral color range: AKA red (often said Aka crimson red), MOMO red (slightly lighter than Aka red, pink/orange red), ANGEL SKIN pink (often said angelic face), pink, white.
Corals are famously produced in two areas, from Japan to Taiwan, the Philippines, Australia and New Zealand. The second is the Mediterranean coastal zone.
Due to historical reasons, the mining, processing and sales of red corals around the world are basically completed by Taiwan, which is the most important processing distribution center for corals in the world. About 80% of the raw materials of gem-quality natural red corals come from the Taiwan sea custom to be called Aka red corals, and the other 20% come from the Italian sardines, so this is called sardine red coral.
Italian sardines and Taiwanese acres, they belong to the same calcareous noble coral, both are dense texture, rich color and beautiful gem-quality corals. The basic difference is that the original sardine branch looks wrinkled, and the moisturizer is slightly less moist after thinking. The price of the same specification is lower than that of Taiwan Aka Hong. Aka is rarely seen in the large-sized beads of natural gem-grade red coral, and most of them belong to sardine red coral.
The reason why the Aka red beads above 8MM necklaces or bracelets are almost invisible is that the aka reds ground into round beads are usually very many holes and white flowers that cannot be used as ornaments, so the large-scale beads of Aka red coral are carved and literally made into bead bracelets or bracelets.
No matter in any place, see large size natural crimson coral bead bracelet or necklace, look at its surface can be fine, sardine red is almost dark red without the corresponding Aka gloss high, the same gem grade red coral but the wormhole or white spot of the sardine will be less than the Aka, the surface is very smooth. If you look at it too much, it is still easy to distinguish.
