The Elizabeth Taylor Diamond, formerly known as the Krupp Diamond, is a diamond that was bought by Richard Burton for his wife, Elizabeth Taylor in 1968. The Krupp diamond was one of a number of significant pieces of jewellery owned by Taylor, her collection also included the 68 carat Taylor-Burton Diamond, which was bought by the couple in 1969. The Krupp diamond was sold by Taylor's estate in 2011 for $8.8 million.〔("The Krupp Diamond" )〕〔CNN Larry King Live. ("Interview with Dame Elizabeth Taylor" ). Aired February 3, 2003.〕 ==Description== The Elizabeth Taylor Diamond is an Asscher cut diamond with a fairly large culet facet, indicating it was likely cut before the 1920s, when culet facets were being phased out. A report (1132411262) dated 9 May 2011 from the Gemological Institute of America states that the diamond is D colour, VS1 clarity; accompanied by a diagram indicating that the clarity may be potentially internally flawless. There is a supplemental letter from the Gemological Institute of America stating that the diamond has been determined to be a Type IIa diamond. Type IIa diamonds are the most chemically pure type of diamond, and often have exceptional optical transparency. Type IIa diamonds were first identified as originating from India, particularly from the Golconda region, but have since been recovered in all major diamond-producing regions of the world. Famous examples of Type IIa diamonds are the 530.20 carat Cullinan I and the 105.60 carat Koh-i-noor. 〔(【引用サイトリンク】title=Diamond transparency )〕 The supplemental letter from the GIA is accompanied by a monograph from the Gemological Institute of America which features additional photographs, data collection charts and gemological research which details the rarity of the Elizabeth Taylor Diamond. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Krupp Diamond」の詳細全文を読む スポンサード リンク
