STAY AWAY FROM THIS JEWELER. MY DIAMOND FELL OUT!!

DO NOT PURCHASE FROM BRILLIANT EARTH. FAULTY WORK!! MY DIAMOND IS LOST :( if I could give negative stars, I would. it was my 20-year wedding anniversary. we could have gone anywhere for my upgrade.. but stupidly, we chose brilliant earth. I chose a beautiful, near flawless, 2ct diamond. Diamond alone was 20k. and not even 6months MY DIAMOND FELL OUT!!!I i have no idea when or where..omg. I retracted my footsteps all day... gutted is how I feel. I am literally depressed! I had my older diamond ring for over 20 years and no issues, and not even 6 months of wearing my ring from brilliant earth-- I lost my diamond!! like wtf!! I called the company and they can not do anything for me. I suggested having them look at THEIR prong workmanship, and they said it's out of their warranty period and could not do anything for me. ARE YOU FREAKING KIDDING!!! I'm literally sick to my stomach!! at such a large cost, they should have a better warranty for THEIR FAULTY WORKMANSHIP !!! and now I won't even wear my band or obviously my ring without the diamond. I'm literally depressed about it, and I asked them ' could they please buy them back', and they don't even want to work with me, they said I could purchase another diamond to replace. ARE YOU JOKING! honestly, if I lost my ring..ok. I'd be upset. but this scenario is: THEY DO POOR WORK. THEIR PRONG LET MY DIAMOND GO. THEY SHOULD HAVE SOME WARRANTY FOR THEIR SETTINGS AND THEIR PRONGS!!! IT'S NOT EVEN BEEN A YEAR, LET ALONE 6 MONTHS!!!!! gutted. pissed. angry. heartbroken. and so disappointed!! there are so many jewelers, STAY AWAY FROM THIS CRAP SHOW OF A JEWELER!! ...Read More
