How can I make that claim? Easy, it has two laboratory valuations; one from America’s largest gem laboratory (IGI) and one from the world’s most prestigious laboratory (GIA). The weight of the diamond is 1.79ct with an F color grade and VS clarity. That means it is impossible to see anything with the naked eye. So, we are talking about a near-flawless diamond of high color. This is Vanderbilt or Rockefeller grade. It is mounted in plumb 18K white gold and accented with 2 unique pentagon-shaped side diamonds. Because of a most favorable purchase, we will extend this ring to our clientele for half of the gemological appraisal. It falls into the investment class. And to make this a complete no-brainer, we will buy it back for at least what you paid for it and possibly even more, per our jewelry buy-back policy. It would be very hard for you to buy better. Complete with Complimentary Hand-Rubbed Rosewood Presentation Box, GIA Report # 2105398094 & IGI Appraisal # 7141502A.
