Featured in this lot is this 2.95ct Tanzanite diamond enamel 18k yellow gold ring with GAL and GIA paperwork. The ring is wonderfully and professionally crafted 18k yellow gold construction that shows an 'Oscar Friedman' hallmark on the inside of the ring band. The center stone is a natural cushion modified brilliant cut tanzanite that shows measurements of 8.51 x 8.48 x 5.34mm with blue violet color hue, moderate saturation and transparent with a total weight of 2.95 carats. The center stone is profusely decorated with a total of 50 round brilliant cut diamonds that show a color hue of G-H and a clarity of VS-SI with a total approximate diamond weight of 1.13 carats. There are four ribbon sections of blue enamel stringing around the ring. 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 GAL(Gemological Appraisal Laboratory of America, Inc., a GIA certified lab GAL Appraisal Number#: GAL202211727) report and appraisal confirming the above information and giving a total value of $14,900.00. GIA (Gemological Institute of America) Tanzanite Grading Report#: 1166950352. The ring size is US 6 1/2. RN032366*
