Featured in this lot is this opulent 3.73 carat tanzanite, diamond, and platinum ring with AIGL paperwork. The ring features a polished, stamped, and tested platinum ring with a bright finish and an 'Orianne' stamp next to a 'PT950'. The ring features an oval modified brilliant cut tanzanite with measurements of 10.9 x 8.9 x 5.7 mm, violetish blue coloration, a very good cut grade, and a total weight of 3.73 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 center stone and vintage shoulders is profusely decorated with a total of 146 natural round brilliant cut diamonds; the diamonds have measurements of 1.1 - 2mm, clarity of VS2 – SI2, a color gradient of G – H, and a total weight of 1.66 carats. The piece comes complete with AIGL Inc. (American International Gemological Laboratories, Inc. a GIA certified lab AIGL#: K66E99-EA16416) report and appraisal, confirming the above info and giving a total value of $17,397.00. The ring size is US 7 1/4.
