Hello, I just found your site a few days ago and have been reading and enjoying your information on CZs. I can’t believe someone who is the Diamond Guy cares about us Cubic Zirconia people. It really touched my heart, and I just want to say thank you. Now for my question. I have searched your question archives, but can’t seem to find this information. I have a diamonique 1ct marquise cz set in a 14k yellow gold ring. It has six prongs holding the stone. I just got it on an auction type web site so it was used, but it’s pretty. The cz seems to really sparkle when I first clean it, but after a little while it doesn’t look as bright as it did when I first cleaned it. After reading many of your other cz answers, I thought I could order a 1ct marquise cz from Jewelers Direct for $12.00 and have the old stone replaced. I called a few jewelers in my area and got over the phone estimates ranging from $8 to $60. I explained that I just wanted them to take out the old cz and put in the new one. So I was surprise at the price difference. Can you give me some insight on what this job should cost. I don’t know how old the ring is ,and I don’t know what type of wear it had before I got it, so I don’t know the condition of the prongs. They look okay to me and the stone doesn’t feel loose at all, but I am not a jeweler so I can’t say if they need any work or not. If it would be just a simple switching of the stones, what would be a reasonable price to pay? Is it unreasonable to ask a jeweler to do such a thing? Thank you for your time and consideration.   Ruth
