最近幾週天氣酷熱難耐，穿著清涼之餘，塗上防曬乳後，不少人會想搭配閃亮的珠寶點綴造型。但您知道嗎？有些珠寶其實和您一樣「怕曬」！接下來，JDC 將為您介紹哪些寶石和金屬不宜長時間曝曬，哪些相對耐曬，並分享一些修復「曬傷」珠寶的方法和建議。
The weather has been scorching hot over the past few weeks, and sometimes you just have to dress lighter than usual. After applying sunscreen, you may want to add some extra sparkle, such as a piece of jewellery, to complete the look. But have you ever thought that some jewellery is just as “afraid” of the sun as you are? In the following, JDC will introduce you some gemstones and metal that can and cannot be exposed under the sun for too long. And share some recommendations to “fix” the broken ones.
怕曬的寶石 Gemstones
珍珠 Pearl
- 紫外線會使珍珠層脫水，導致變黃、表面龜裂，並永久失去光澤。養殖珍珠和天然珍珠都難以倖免。
- UV rays dehydrate nacre, causing yellowing, surface cracking, and permanent loss of luster. Both cultured and natural pearls are vulnerable.
珊瑚 & 琥珀 Coral & Amber
- 陽光會漂白珊瑚的鮮豔色彩並增加其孔隙。琥珀則可能出現表面細紋並變脆。
- Sunlight bleaches coral’s vibrant colors and increases porosity. Amber may develop surface crazing and becomes brittle.
紫水晶 Amethyst
- 長時間的紫外線照射會分解其中的鐵元素雜質，導致深沉濃郁的紫色褪成淺棕色甚至無色。
- Prolonged UV exposure can fade the rich purple hue to pale brown or colorless due to the breakdown of iron impurities.
托帕石（粉/黃色）Topaz (Pink/Yellow)
- 容易褪色；尤其是「帝王托帕石」，褪色速度更快。
- Prone to bleaching; “Imperial Topaz” varieties fade quickly.
孔賽石 & 粉晶 Kunzite & Rose Quartz
- 孔賽石的粉紅色可能完全消失；粉晶則可能褪成灰白色調。
- Kunzite may lose its pink color entirely, while rose quartz can pale to grayish tones.
蛋白石 Opal
- 含有 6-10% 的水分，對熱非常敏感。高溫可能導致其產生裂紋或脫水起霧。
- Contain 6-10% water, opals are sensitive to heat which can cause crazing and dehydration hazing.
怕曬的金屬 Metal
純銀 (925 銀) Sterling Silver
- 紫外線會加速其氧化變黑（形成硫化銀），需要更頻繁且用力地拋光，所以會磨損到精細的設計。
- UV ray exposure will speeds up tarnishing, forming black silver sulfide and requiring aggressive polishing that can erode details.
玫瑰金 Rose Gold
- 其中的銅成分在曝曬下會氧化，產生暗沉斑點。
- Copper oxidizes under exposure, leading to dark spots.
白金 White Gold
- 表面的銠鍍層在紫外線下會更快耗損，露出底下偏黃的金基底。
- Rhodium plating degrades more quickly under UV, revealing the yellowish base.
鍍金飾品 Gold-Plated
- 高溫可能使鍍層與基底金屬的結合變鬆，導致剝落。
- Heat may loosen the bonding, causing peeling.
如何避免珠寶被曬到？Sun-Avoidance Protocols
⚠️請避開烈日時段！Timing!
如果您在紫外線最強的時段（上午 10 點至下午 4 點）時在戶外，請；盡量摘下珠寶。
⚠️請遠離高溫環境！Temperature!
避免將珠寶留在車內或窗台邊等溫度可能超過 40°C (104°F) 的地方。
Avoid leaving jewellery in cars or windowsills where temperatures exceed 40°C (104°F).
甚麼時候塗防曬才不會影響珠寶首飾？Application
佩戴珠寶前至少 15 分鐘塗抹防曬乳。不能使用含有氧苯酮 (oxybenzone)、阿伏苯宗 (avobenzone) 或果酸 (AHAs) 的防曬產品，它們可能腐蝕金屬、使寶石霧化。長時間曝曬後，用超細纖維布擦拭珠寶，去除殘留的防曬乳或汗水。
Apply sunscreen at least 15 minutes before wearing jewellery. Avoid formulas with oxybenzone, avobenzone, or AHAs as they can corrode metals and cloud stones.Wipe pieces with a microfiber cloth after prolonged sun exposure to remove residues.
我應該如何收納珠寶首飾？Storage
- 將珠寶放入密封盒內的防氧化絨布袋中，放入乾燥劑（如矽膠包）吸收濕氣。
-
Use anti-tarnish pouches inside sealed boxes. Include silica gel packs to absorb moisture.
我應該如何清潔珠寶首飾？Cleaning
溫和清潔 Gentle method
- 使用溫水加中性清潔劑及軟毛刷輕刷。
- Lukewarm water + pH-neutral soap, and a soft-bristle brush.
銀飾除黑 Silver tarnish
- 容器內鋪鋁箔紙，亮面朝上，銀飾浸泡在加入小蘇打粉的熱水中約 10 分鐘 。之後用鑷子夾出銀飾，冷水沖淨殘渣。使用棉布擦乾後，再用拭銀布拋光恢復光澤。
- Wrap the aluminum foil around a container, with the shiny side facing up, and soak the silver jewelry in hot water with baking soda for about 10 minutes. Then use tweezers to remove the silver jewelry and rinse it with cold water to remove any residue. After drying with a cotton cloth, polish it with a silver polishing cloth to restore its luster.
專業養護 Professional Care
- 每年進行專業檢查，查看鑲爪是否鬆動或開始有損壞的跡象。
- Annual inspections for loose settings or signs of early dama
有甚麼耐曬適合日常配戴的選擇？Sun-Resistant Alternatives for Daily Wear
金屬 Metal
- 鉑金、鈦金屬或不鏽鋼，較能耐熱抗變色。
- Platinum, titanium, or stainless-steel resist heat and tarnish.
寶石 Gemstone
- 鑽石、藍寶石、紅寶石，不易因紫外線/高溫而褪色。
- Diamond, sapphire, and ruby withstand UV/heat without fading.
我可以戴珠寶首飾去沙灘嗎？Special Case: Beach/River Exposure
海水 Sea water🌊
- 加速純銀氧化變黑，並侵蝕珍珠層。活動後應立刻用清水沖洗珠寶。
- Accelerates silver tarnishing and erodes pearl nacre. Rinse jewelry immediately in fresh water.
沙粒 Sand🏝️
- 可能會輕微刮到黃金和軟質寶石；避免在沙灘佩戴有複雜紋理的鏈飾(如拜占庭項鍊)。
- May micro-scratch gold and soft stones; avoid wearing textured-chain pieces (e.g., Byzantine) in sandy areas.
珠寶損壞了有甚麼補救方法？When Damage Occurs
- 自己在家裡是無法修好的。請諮詢寶石學家，尋求專業處理方案（如紫水晶的輻照改色）或考慮更換寶石。
- No home restoration is available; consult a gemologist for treatments like reirradiation (for amethyst) or replacement.
- 請立即停止佩戴！金屬因熱膨脹而導致變形，若盡快交由珠寶師傅處理，有可能恢復原狀。
- Stop wearing the piece. Thermal expansion may be reversible if addressed quickly by a jeweler.
