Business ProfileforDunkin's Diamonds

I purchased a 26,000 dollar stone for an engagement ring for my wife. went in, hand picked the stone, picked the setting. had the ring made. I got my certification for having a perfect stone, appraisal, etc stating perfect stone. well my wife left me and left the ring behind so I start going around trying to sell the ring. little did I know the stone was chipped..... and the first jeweler said it was done during setting. from their I went to Dunkins and they told me that there is no way to prove anything. I took it to another licensed gemologist and he again said it was done during setting of the stone. corporate manager initially called me one day and said "yeah with that chip we just aren't interested" I called into the store and spoke to a manager and told her everything ive learned and still no resolution. ignoring the fact I had licensed gemologists look at it. I went a step above and even got a THIRD opinion.. same result. Dunkin had me take the ring in to have their lady look at it.... naturally she said that there's no way to prove. so 3/4 people say its a defect from them and they won't acknowledge. I want my money back. plus 10,000 because of the lies, deceit and treatment ive incurred ov4er the past several weeks. they say they will replace the stone. but when I was in there they tried to get me to talk to a purchaser who said they can get that same stone for 3,000 dollars and they think thats what I want??? I paid 30,000 for a defective ring. I never would have purchased knowing it was damaged and basically worthless.....
