There are two types of jade. Nephrite (a silicate of calcium and magnesium) and Jadeite (a silicate of sodium and aluminum). The more valuable of the two is Jadeite. The value of fine Jadeite is determined on several factors. Jadeite comes in many colors (including lavender and red), but green is the color that is most coveted. The jewelry industry recognizes the highest quality jade by their medium tone, very bright green hue, color uniformity, translucency, clarity, and saturated color. With East Queen Jade jewelry, we offer one of the biggest selection of jade jewelry in Chicago land.
