如果您曾涉足鑽石首飾市場,您可能聽說過“GIA 認證”一詞。但是有人知道這意味著什麼嗎? GIA 代表美國寶石學院。但是當您聽到“GIA 認證”或“GIA 認證”鑽石這兩個詞後,這兩個術語在技術上都是不正確的。 GIA 不“認證”或評估任何鑽石;它對它們進行評分。但是,很多人在談到 GIA 評估的鑽石時會使用“GIA 認證鑽石”這個詞。

GIA 鑽石可能是您在購買戒指時會看到的一個術語 – 由 GIA、4C 標準的創建者和獨立鑽石權威機構評級的鑽石的簡稱。詳細了解 GIA 鑽石以及精明的購物者為何依賴 GIA。

GIA 認證不會開採鑽石,也不會進行商業買賣或交易。它不評估鑽石,也不參與鑽石定價或估價。 GIA 認證工作不受這些商業利益的幫助,前提是其鑽石等級檢驗完全沒有塗漆和不偏不倚。

多年來,GIA 認證一直處於科學和地質研究的前沿,並因使用非常嚴格的鑽石分級流程而享有盛譽。當一顆鑽石被送到 GIA 鑑定所時,它會經過多次測試和評估,以確認其分析的高度準確性。

所有鑽石均通過 GIA 認證分級。雖然看起來應該是這樣,但考慮到市場上 GIA 分級鑽石的絕對數量。這種重要性可能證明了信仰珠寶商及其客戶在 GIA 客觀和獨立的分級服務中的地位。

高級珠寶商確保我們手工挑選了所有鑽石,並提供超大尺寸的 GIA 鑽石可供選擇。 “GIA 認證”一詞不准確,但仍有許多人在使用……恰當的時機是“GIA 鑽石證書”。 GIA 鑽石證書意味著選定的寶石已通過 GIA 嚴格的標準來檢驗其質量。 GIA 鑽石證書考慮四個主要因素:切工、淨度、顏色和克拉重量。事實上,根據 GIA,“分級”可能是比“認證”更準確的術語來解釋該方法。

為確保您的鑽石經過 GIA 分級,請要求製作其 GIA 分級報告。除了對鑽石的 4C 進行全面檢查外,GIA 證書還包含一個特定編號,有時會刻在鑽石的腰圍上。您將使用證書編號訪問 GIA 的在線全球證書數據庫 GIA Report Check,以驗證鑽石是否經過 GIA 分級並檢查其所有分級詳細信息。

鑽石被分配了一個等級,該等級由支持上述每個因素的預定等級支持。其中許多因素是不言自明的。顏色和淨度按比例排列,而克拉重量確實支持鑽石的重量。

GIA 認證還著眼於鑽石構成的其他方面,例如載荷分佈的均勻程度、形狀、對稱性以及拋光程度。鑽石越精確、越白、越對稱,其等級就越高。較低質量的鑽石被分配較低的費率。儘管您總是在戒指廣告中聽到有關鑽石的“GIA 認證”一詞,但 GIA 實際上會評估各種寶石。如果您需要擁有 GIA 評估的寶石首飾,他們會提供幫助。您必須郵寄或親自遞送您的寶石或寶石首飾。不過,一旦經過評估,您將連同評估過程的官方文檔一起取回。

GIA 鑽石證書可能是質量的保證。它讓您放心,公正的第三方已經檢查並評估了寶石的質量和真實性。珠寶是作為附屬品的投資。您希望確保您物有所值。

Nissan, David and his team were extremely accommodating, understanding and patient with our purchase. They took the upmost care to find the best solution for our needs and went above and beyond normal ‘customer service’ standards. I have absolutely no qualms recommending their products and services. Both were absolutely flawless. I will continue to sing them praises and will most definitely purchase from them again in the future. Thank you again!

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
