Business ProfileforCrazy Diamond Johnny Inc.

My friend bought 2pcs of necklaces (18k) here at I love diamonds.she told ***************************** and *********************** that she wanted to change the lock of the necklaces from a spring clasps to a lobster clasps 18k of gold.they all agreed to change it with 18k lock. After a week the daughter of my friend found out what I love diamonds did.they changed the lock with 10k,14k,18k lock all connected to the necklace all stamped.she went back to the store and told them what her daughter found out about the necklace,they are very sorry and told her they dont have 18k lobster clasp.if her daughter didnt found out she will be forever clueless.In that incident Im afraid for the engagement ring and wedding band that me and my fianc both here that we paid over 8 thousand dollar,so we dropped the jewelry to IGL laboratory in *******.we found out that the engagement ring is 14k supposed to be 18k and the Center stone is certified as per I love diamonds and we were told also the piece was used.We went back to the store and talked to **** and told him what we found but ******************* insisting that the pieces is 18k and its the factory fault.I told him too that the diamonds is not certified because if that certificate it will stated to the certificate the inclusion of the diamonds.**** is clueless that the diamonds has indented natural.so the diamonds is not certified?!**** was upset and I was told were fighting over $10 different to a gold of 14k over 18k.The point is..is the wedding and engagement ring used?why one of the pieces is 14k?is the Center stone certificate?Be very careful buying jewelry to this store if you have a chance always takes the jewelry to a laboratory to look at.two people to mess up is enough proved that something sketchy to this store.
