• 就是呢，藍色的比綠色的貴，主要是我看有人戴，都不是很大，那個藍色真的很好看呢。 -燕然山- ♀ (0 bytes) () 03/05/2023 postreply 08:22:32

• 藍的顏色是銅離子，像硫酸銅（也叫藍礬，用於波爾多液），在溶於水中成為絡合離子呈藍顏色， -xia23- ♂ (805 bytes) () 03/05/2023 postreply 09:43:59

• 對，你學習得可以，含銅多的就顯藍，綠鬆石親水，保養綠鬆石就是把綠鬆石放到蒸餾水裏養養，礦泉水都不行。 -燕然山- ♀ (0 bytes) () 03/05/2023 postreply 11:35:01
