Although it’s true there are only so many “floral” style designs in a pendant, this looks a lot like both Van Cleef & Arpels and Louis Vuitton fine jewelry. But the good news is it’s from Blue Nile so it’s a lot more affordably priced.
The site explains, “Delicate in design, this pendant features a beautiful sapphire gemstone surrounded by sparkling micropavé diamonds framed in 14k white gold.” It comes with an 18 inch chain, but the stone carat weight was not stated.
This sells for USD$413 (with a discount promotion current at the time of writing).
