Zale Jewelers / Zales.com review: Defective opal pendant

In March of 2022, my husband bought me a very pretty, delicate opal pendant necklace. Because it is so delicate, I don't wear it very often but have a number of other opals that I wear 24/7 with no issue. I was wearing the necklace recently when I noticed that the pretty opal was now a clear yellow stone that my personal jeweler swore was citrine! I contacted customer service after visiting a store location who explained that after doing a google search, it must be an Ethiopian opal which changes with exposure to water, heat, body sweat, etc. They offered to replace the stone as long as I covered the metal work cost which was estimated at $135. Several weeks later, I received a call that the two small diamonds were loose and had to be secured for another $40 which was mandatory. This past Sunday, my husband and I went to pick up my repaired necklace. The stone was a clear yellow with few opal characteristics! I refused to take possession and again contacted customer service. Their response was defensive stating that they replaced the stone at their cost of $260 as a courtesy and that it was the same quality as the one replaced. I have yet to decide if I want my $322 necklace back. Below are photos of the original opal and the same stone in its citrine state. I did not take a photo of the replacement.
