Both Sapphires and Rubies make great center stones for everyday wear. Their evaluated on three qualities: hue, tone and saturation. Sapphires come in all the color ways including white, which resembles a diamond for a more cost effective option. Therefore, to understand a sapphire and ruby’s' qualities, we depend upon the Gemological Institute of America’s (GIA) globally accepted standard for describing stones, see the 4 Cs of diamond quality here.
Moissanite, originally discovered in 1893 in a meteor crater, is a very rare and scarce material as it comes from space. Therefore, moissanite as we know it is almost exclusively lab grown, meaning it’s anatomically the same as the real stone, just grown in a laboratory. Moissanite is a great option for a diamond alternative as it is the hardest stone besides a diamond and given great color and cut will shine beautifully.
Salt and pepper diamonds are all unique in their color and windows which show carbon deposits. They are a great stone in terms of everyday wear and each one is truly one of a kind.
