I have used Gold Works to size rings up and down and have been extremely pleased. You cannot see any imperfections in their work. They take pride on pleasing the customer. I have also purchased some 14kt earrings, because the price was awesome. I did not even plan to make a purchase, but I could not pass up their prices. I was very pleased with the over all treatment and work performed. I will continue to use them in the future for my jewelry needs and wants.
