Three diamonds will be offered this year: a 5.53-carat fancy blue at auction scheduled in Geneva on November 9, a 3.24-carat diamond and a 2.08-carat diamond in New York on December 7th. De Beers and Diacore paid a total of $ 40.36 million for five rough blue diamonds from the Cullinan mine weighing 85.62 carats in November 2020. In nearly two years, Diacore has cut and polished the five rough stones to create the eight blue diamonds from the collection that Sotheby&#8217;s now presents.<br \/>\nThe valuation of diamonds of this type is quite difficult. Suffice it to say that the 11.29 has an estimate of between 28 and 50 million dollars.<br \/>\n<figure id=\"attachment_73364\" aria-describedby=\"caption-attachment-73364\" style=\"width: 709px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera.jpg\" alt=\"La miniera di diamanti Cullinan\" width=\"709\" height=\"531\" class=\"size-full wp-image-73364\" title=\"\" srcset=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera.jpg 709w, https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera-300x225.jpg 300w, https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera-73x55.jpg 73w, https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera-400x300.jpg 400w, https:\/\/gioiellis.com\/wp-content\/uploads\/2019\/05\/cullinam-miniera-100x75.jpg 100w\" sizes=\"auto, (max-width: 709px) 100vw, 709px\" \/><\/a><figcaption id=\"caption-attachment-73364\" class=\"wp-caption-text\">La miniera di diamanti Cullinan<\/figcaption><\/figure><br \/>\n<figure id=\"attachment_110541\" aria-describedby=\"caption-attachment-110541\" style=\"width: 709px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu.jpg\" alt=\"The De Beers Exceptional Blue Collection\" width=\"709\" height=\"523\" class=\"size-full wp-image-110541\" title=\"\" srcset=\"https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu.jpg 709w, https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu-300x221.jpg 300w, https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu-480x354.jpg 480w, https:\/\/gioiellis.com\/wp-content\/uploads\/2022\/10\/diamanti-blu-678x500.jpg 678w\" sizes=\"auto, (max-width: 709px) 100vw, 709px\" \/><\/a><figcaption id=\"caption-attachment-110541\" class=\"wp-caption-text\">The De Beers Exceptional Blue Collection<\/figcaption><\/figure><br \/>\n<script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><br \/>\n<!-- rettangolo grande --><br \/>\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:336px;height:280px\"\n     data-ad-client=\"ca-pub-1422720793454724\"\n     data-ad-slot=\"8343610496\"><\/ins><br \/>\n<script>\n(adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><br \/>\n<script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script><br \/>\n<ins class=\"adsbygoogle\"\n     style=\"display:block\"\n     data-ad-format=\"autorelaxed\"\n     data-ad-client=\"ca-pub-1422720793454724\"\n     data-ad-slot=\"9203601299\"><\/ins><br \/>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><br \/>\n<\/p>","protected":false},"excerpt":{"rendered":"<p>Color challenges for diamond enthusiasts (and investors).
