No I did this too... I jumped into the Tiffany yellow diamond DBTY pendant a little too quickly! Don't get me wrong I love it, every time I look at it it is so stunning and really does sparkle like a diamond but with this sunshiney colour, it's amazing! But it was SO expensive for this "little" diamond (it's .91 carats but it's not like this big soleste pendant which is where I started which does have more pa-pow!) and I've always felt uncomfortable... I actually didn't wear it for a year! I was partially afraid something so expensive but so delicate would break... and partially thinking I might return it if they would let me. Trying to get over it b/c I love it and just have it be my everyday necklace! Feel really stupid though!
Also currently selling my Cartier Orchid pave pendant. DEFINITELY an impulse buy and although I LOVE it, I don't wear it enough to justify!! breaks my heart when I look at it b/c it's SO PRETTY!!! But I don't need it! I decided to keep the yellow diamond and sell the orchid. Sad but feel like it's the right thing to do!
Good thread!
