Different from the real black coral, this golden sea willow is named sea willow because it grows into a tree with slender branches and flexible texture, and its appearance is similar to that of willow trees on land. Although it looks like a tree, through marine scientific research, it is a marine animal, belonging to coelenterate and one of Corallinae. 1. Not afraid of hand sweating? After playing, sweaty hands should be dried with cloth or gloves. They are as bright and clear as patterns. 2. Not afraid of fakes? The identification of sea willow is the simplest-look at sea willow with a magnifying glass. Does it have ultra-fine perforated leaves that can be called sea willow veins? There is no way to fake this. 3. Not afraid of falling? Jadeite, crystal, jade and other bracelets are beautiful and afraid of being knocked off. Why? Jade bracelet? The market is not very successful because. 4. Not afraid of open flames? Sea willow won't catch fire in an open flame, which is another magic. 5. Play with change? It will not change like jade, and the color of sea willow will become redder and redder after playing with it, and the patina will be brighter than glass. Very beautiful. 7. God knows how things change-sea willow also has the function of "barometer". Before the wind and rain come, the bright surface of sea willow products will become dull, and it will feel wet to the touch, and the weather will clear up and return to its original state.
