Genuine Tiffany Yellow Diamond Engagement Ring

.4 carat very yellow ("fancy vivid yellow" - the most yellow rating within Tiffany's rating system) flawless center diamond on a platinum setting with .16 carats of white pave diamonds. Currently size 5... closer to 4.8. Tiffany retail price was $8,550 on August 31, 2023. I can provide the pouch (shown in photo) and a beautiful small Tiffany shopping bag, but not the original box. This ring says: femininity, tradition, genuine-ness, and quality over quantity... yet also newness and originality.
