Featured in this lot is this opulent tanzanite VS2 diamond and 18k white gold ring with AIGL paperwork. The ring features a wonderfully and professionally crafted 18k white gold construction that shows an 'Orianne' hallmark that shows a '18k' gold stamp next to the hallmark and reads underneath 'D 0.60cts.' The centerstone is a natural cushion modified brilliant cut tanzanite gemstone that measures 8.4 x 8.3mm with bluish violet color and a very good cut grade and a tyotal weight of 2.91 carats. The centerstone and double pave shoulders are decorated with a total of 40 round brilliant cut diamonds with measurements of 1.1 - 1.8mm and shows a VS2 - SI1 clarity and shows a coloration of F-G and a total weight of 0.60 carats. Tanzanite is a very rare precious gemstone that is only found in the Usumburu Mountains that border the Umba Valley of northern Tanzania. It was originally discovered in 1967 by Tiffany & Company, who named the stone Tanzanite. This example is unique due to its exceptional pleochroism (an optical phenomenon in which a stone has different colors when observed at different angles). The piece comes complete with AIGL Inc.(American International Gemological Laboratories, Inc. a GIA certified lab AIGL#: K39E88-EA16208) report and appraisal confirming the above info and giving a total value of $10,967.00. The ring size is US 7.
