Prior to purchasing, I did a lot of research on sapphires. Turns out, The Natural Sapphire Company met all the criteria I was looking for: natural untreated sapphires accompanied with written documentation to verify their origin & authenticity. It took me four months to finally pick out the ideal gems to have them crafted to rings. Caitlyn was extremely patient with me. The entire process was conducted via email and she is very responsive and helpful. She and her production team made me the most beautiful set of sapphire rings I can dream of: yellow, green, and purple sapphire rings. Complement follows whenever I wear them. With their large selection of quality sapphires, honest business integrity, and outstanding customer service, they have gained another loyal repeat customer. I will not hesitate to recommend them for my family & friends.
