3. 與信譽良好的珠寶商一起檢查「4C」
在挑選合適的戒指前,更重要的是要找到值得信賴的珠寶品牌。建議先從家人和朋友推薦的品牌或廠商下手。一旦確定了品牌,在挑選戒指上也會更有方向。你可以開始探索黃金、鉑金等不同的金屬類型,了解各式各樣的戒指形狀和款式,以及天然寶石和人工培育寶石的區別。如果你知道另一半是鑽石愛好者,可以先行向珠寶商了解「4C」標準:Color顏色、Clarity淨度、Cut切工、Carat克拉。這些因素會決定整顆寶石的外觀和價值。舉例來說,高淨度的寶石比較不會有肉眼可見的內含物,顏色標準較低的可能會呈現暖色調。而 4C 當然也對戒指的價格有關鍵的影響力。此外,你也應該確保寶石已經過 GIA(Gemological Institute of America)國際認證。
