紅銅 Copper
銅具有較高的純度。未經氧化時呈現玫瑰紅色；經氧化後則轉為深啡色，為本身偏冷色調的金屬製品增添一種溫暖的質感。
紅銅在氧化過程中會產生對人體無害的氧化物。然而，在佩戴紅銅飾品時，這些氧化物可能會在皮膚上留下啡色、灰色或黑色的痕跡。若持續佩戴，這些痕跡會持續出現；若停止佩戴，則一般會在數日內自然消退。
對於皮膚較為敏感或容易出現過敏反應的人士，建議選擇低致敏性的貴金屬，例如純銀、18K金或鉑金。
Copper has a high level of purity. Before oxidation, it has a rose-red color; after oxidation, it turns dark brown. This adds a warm tone to metal products, which are generally cooler in color.
When red copper oxidizes, it produces oxides that are harmless to the human body. However, when wearing red copper jewelry, these oxides can leave brown, gray, or black marks on the skin. If worn continuously, the presence of oxides will persist. If not worn, the marks will naturally fade after a few days.
For individuals with sensitive skin prone to allergies, it is recommended to choose hypoallergenic precious metals such as pure silver, 18K gold, or platinum.
銅材質重要須知
Important Notice of Copper Materials
．不適合對金屬過敏或皮膚敏感人士佩戴（低致敏選擇：925純銀或18K金）
．銅氧化後所產生的氧化物對人體無害
．佩戴銅飾時，氧化物可能於皮膚表面留下深色痕跡
．相關痕跡一般可透過清洗雙手或取下飾品後逐漸淡化
．紅銅會隨時間氧化，呈現玫瑰金或深啡色調變化
．色澤屬自然變化，不會固定為單一顏色
．銅飾接觸水分後，請盡快擦乾以減慢氧化
．進行游泳、沐浴或浸溫泉等活動前，建議先取下飾品
．NOT SUITABLE for allergies or sensitive skin. (Hypoallergenic options : 925 Silver or 18K Gold)
．Oxides from copper are harmless to human
．Wearing copper jewellery may leave dark marks on the skin due to copper oxides
．The marks generally fade after washing hands or taking off accessories
．Red copper oxidises, resulting in shades of rose gold or brown
．The hue is a natural variation and does not oxidise to a specific colour
．Dry copper accessories immediately after getting wet to prevent oxidation
．Remove accessories before water activities like swimming, bathing or hot spring etc.
