Every sapphire we have is a unique stone created by mother nature, which is cut and polished to show off that one stone's color and luster, bringing out the individual character of each gem. Once the sapphire is certified, we hand pick a unique custom ring setting to be made, which is then set by hand for that stone. It takes approximately 3 - 4 months from when a sapphire is hand picked to having the sapphire set and listed for sale at wholesale price. We do keep a wide selection of loose natural sapphires in stock which are not set, so please contact us if you have any questions on any one of our natural sapphire rings or a custom ring setting which you might be considering.
