Sapphire is one of the Big 3 of jewelry gemstones—the other two are ruby and emerald. Sapphire is a durable stone that’s the best known blue gem, as well as being available in most colors.
The most highly valued blue sapphires are velvety blue to violetish blue, in medium to medium dark tones. Preferred sapphires also have strong to vivid color saturation. The saturation should be as strong as possible without darkening the color and compromising brightness.
Blue sapphires often have some inclusions. Blue sapphires with extremely high clarity are rare, and very valuable. Price can drop if the inclusions threaten the stone’s durability. Kashmir sapphires contain tiny inclusions that impart a desirable velvety appearance.
To achieve the best overall color, maintain the best proportions, and retain the most weight possible, cutters focus on factors like color zoning, pleochroism, and the lightness or darkness of a stone.
Care - Sapphire is a very hard gemstone, suitable for daily wear. Care should be taken when storing your Sapphire Jewelry to avoid scratches. Store your Sapphire separately from your other jewelry in its own box or bag. Natural sapphires can be cleaned safely with steam or an ultrasonic cleaner, however it is recommended that you try cleaning with a damp cloth and mild soap first as this is the preferred method.
