越來越多的人開始購買黃金首飾，無論是送給家人、長輩、朋友，還是自己穿著都很好。 它具有美好的含義和得體的外觀。 那你知道如何挑選金飾嗎？ 一般要有代號、材料名稱、含量標誌等。 製造商的。 沒有這些資訊的黃金首飾就是不合格產品！不要相信推銷員所說的。 購買金飾時，最應該關心的是它的“顏色”，即金飾中黃金的含量。 看分數標記 分數鑑定是以百分比和千分之一表示的黃金首飾中的含金量。 例如，如果標示G990或Au990，則表示這款黃金首飾的含金量為99%；若標示G586或Au586，則表示其含金量為58.6%。 前者含金量較高，成色較好，當然價格也較貴。 選擇時只要看分數標識就知道含金量了。 看文字標記 有些黃金產品除了刻痕外，還會有文字標記，更簡單清晰。 只有2個字－純金（含金量不低於99.0%的黃金）。 此外，還有鑲嵌金屬、千足金等標誌，是指含金量不低於99.9%或99.99%的金飾。 不過，我國已經取消了鑲嵌金屬和千足金的命名，這兩個標記將不再出現在金飾上。 黃金在手有下墜的感覺，銅在手重但無下墜的感覺。 純金和足金首飾的純度非常高，非常穩定。 珠寶項鍊墜落或互相碰撞的聲音會沉悶而平穩，有拍打聲，墜落時不會動；品質差、純度低的甚至假金落地或相互碰撞時，會發出「當」的金屬聲，有時還會跳動聲音，落地後還會跳動。 但不要用力撞擊。 注意變形。 顏色以紅、黃為最佳，但也要注意觀察產品的外觀顏色，不好的顏色是深青色。 有些裝飾品的顏色太暗淡，就像噴出來的油漆顏色一樣。這些都需要仔細檢查。 同時，純金首飾訂製項鍊容易變形，一定要看整體形狀是否變形。 黃金首飾表面的紋理不容忽視。 若要選擇表面清晰、亮度好、紋理均勻的首飾。 購買時也應注意首飾的邊緣是否光滑，好的首飾製作精美。 純金飾品的硬度為2.5，與人的指甲差不多，因此可以用指甲畫出精細的痕跡。 與其他金屬相比，更難彎曲（適合小克重的金飾，如大克金條無法折疊）。
