  1. 鑽石是現今地球上最堅硬的物質,這顆瑰寶自古以來象徵著恆久堅韌的愛,亦是愛侶之間寓言承諾的信物。. 比較一下,你會發現在Diamania迷雅鑽的鑽石價格極具吸引力。. 創立於2013年的迷雅鑽,是紮根香港多年的鑽石樓上鋪,作為經驗豐富的鑽石批發專家,我們 ...

  4. 2020年3月11日 · GIA 是全球公認最權威的鑽石鑑定機構,能確保你購買的鑽石會是物有所值。 使用其他證書 (甚至沒有證書)的鑽石,其質素往往可能是被高估了,不足以採信,所以不建議客人購買。 例如某商家出售其他證書 E VS1 級別鑽石,若是在GIA 評級標準中可能只達到G Si1級別。 即使是鑽石買手,沒有證書之下亦很難準確分析很多方面的標準 (例如是對稱度)。 始終只會購買一次求婚戒指,有信譽的證書才是最佳保障。 GIA 証書必不可少. 3) 完全同級的鑽石,價格差距可以很大. 鑽石是求婚戒指中的靈魂,亦是最影響價格的因素。 鑽石質素當然影響價格,但原來完全相同級數的GIA鑽石,在不同店鋪定價上都存有差距,實際上的差幅大得令人難以想象。 大致上可分成4個層次 (每個分類之中亦有少量差異)

    • What Is ‘Hearts and Arrows’?

    Diamond-Cut refers to the angle of the diamond facets, the proportion of each part of the diamond after cutting and the smoothness of each face. Its purpose is to allow the diamond to successfully condense and reflect most light. Cut is the most complex and technically demanding of the 4Cs. It has very high requirements regarding accuracy and measu...

    The factors of Cut, Polish and Symmetry work together to determine the ideal light reflection of the diamond. Cut – The scale of each facet or proportion of the diamond. Since the scale of each facet, angles and proportion of every diamond is calculated, it needs a suitable standard size to achieve the best internal reflection and refraction to pro...

    The cut of a diamond directly affects the angle and direction of light entering our eyes, and thus the degree of sparkle. A high-quality diamond should have a precise ratio and excellent symmetry, so that the light entering the diamond can be internally reflected by different facets and redistributed into a color spectrum, which is finally refracte...

    The cut proportion of a diamond refers to the relationship between the size and angle of its polished facets. While there is an ideal cut proportion for each diamond, there is no fixed “formula” or proportional value. The ratio is a magical factor that GIA researchers have discovered from more than 70,000 observational tests during the development ...

    The sparkling brilliance of diamonds is the result of optical effects. When light enters the diamond, it effectively gives life to the diamond, directly affecting its visual appeal, especially as the process of moving the diamond is more obvious. The following are terms related to optical effects: Brilliance – Refers to all white light reflections ...

    ‘Hearts and Arrows’ is a mark that was developed by the Antwerp Diamond Appraisal Agency in 2009 and is regarded as one of the criteria for verifying diamonds. The pattern of the heart and the arrow is a symmetrical optical figure obtained by observing the cutting of a round diamond with a special instrument. The round brilliant cut diamond has 57 ...
