Are Tiffany and Company diamonds worth the money? I found a second hand diamond that is from Tiffany and Company online that fits the criteria that I am want in a diamond. It is D in color and VS1 in clarity. It has the ratio that I like of 1.31. I just don't know about these diamonds and to buy something unseen is kinda of scary. I trust that it is authentic but I just question if Tiffany and Company diamonds are better than other diamonds that are not Tiffany and Company. Thoughts?
