You have a really good eye! I ended up keeping both necklaces. The price difference was CAD $300 (14k white gold 0.1 carat SI1 G) versus CAD $2500 (platinum 0.18 carat VS1 G, no fluorescence, excellent polish and symmetry). You can't even tell the diamond apart, both sparkle like crazy. The quality of the gold is great from that Etsy seller. I actually get more compliments from the Etsy necklace because the metal looks whiter. If you don't care about the packaging or branding, please buy from them. I am currently waiting for the arrival of my matching bracelet remember, with gold, you never have to take it off when you shower. That was the winner for me. Also, the bezel is thicker so it looks more like the sterling silver or rose gold style from Tiffany. You can't go wrong with either of these choices though. ))) please let me know what you end up picking! Would love to see your final conclusion!
