Lavender jade is the rarest and therefore the most prized. The term jade is generic; it actually refers to two minerals – jadeite and nephrite. Nephrite and jadeite have been used to carve hard stone since prehistoric times.

Alaska Jade is a stone prized by Alaskans for its vibrant colors and smooth surfaces. The colors range from shades of green to yellow to red, black and white. Lavender jade is prized the most because it is the rarest.
The more green jade, the higher its value. The most expensive examples of jade are in the so-called Imperial Jade color, which is a rich and vibrant emerald green. In order to achieve the highest possible value, jade stone must be as pure as possible and must not show gray or other colored spots.
Alaska’s state jewel is Jade. Rocks are made up of two or more minerals. Alaska does not have a state rock, but it does have a state jewel, Jade.
Myanmar is known to be the source of almost all of the world’s high-quality jadeite, and Kachin State in the north has been known to be the source of jade for hundreds of years.
Very emerald green jadeite, known as “imperial jade“, is also the most valued.
Imperial Jade from Burma is the most expensive type of jade. It is the most expensive because it is the highest quality and most desirable color and is still the most valuable source of jadeite in the world today.
The most important value factor is color, but transparency, texture, clarity, and even the way the stone is cut or carved can greatly affect the final price of a particular piece. Unlike most other gemstones, jadeite is typically sold by the piece rather than by the carat weight.
Grade A means the jade is all natural and has absolutely no treatment. This is the highest quality jadeite available. Class B means it has been treated by bleaching or soaking in hydrochloric/sulphuric acid. This is done to clean the interior of impurities and substandard paint.
Prices and Value of Jade
On average, nephrite jade costs about 0.04 to $0.40 per carat, with most nephrite jewelry ranging from $30 to $60 costs. However, the source of the nephrite stone can affect the price. For example, Canadian nephrite starts at $0.04 per carat, but Chinese white nephrite starts at $30 per carat.
The main difference between jade and jadeite is the quality. Jade has two grades as nephrite and jadeite. Jadeite is considered to be high-quality jade and is rarer and more expensive than nephrite. Jade is a hard, mostly green, gemstone used for ornaments and jewelry.
There were massive deposits of hematite in the tributaries over Egypt. When an earthquake loosened a deposit, it ran into the water, turning it red and deadly to residents downstream. Hematite is also called “Black Alaskan Diamond” although it is neither black nor a diamond.
Alaska is not only blessed with record-breaking gold deposits, but also an extensive variety of base metal minerals and gemstones, some of the most common being Alaskan jade, rhodonite, fluorite, garnet, cinnabar and jasper. p>
Nephrite is one of two gemstone materials, nephrite and jadeite, known as jade. They have a somewhat similar color range and a tough, microcrystalline structure. Both have been used as carving materials throughout history. Of these two minerals, only nephrite occurs in Australia.
Most known deposits of jadeite occur along or near faults in serpentinites. Examples of this type of insoles can be found in Myanmar, New Zealand, Canada, Taiwan, Guyana, Suriname, Southern Europe, Russia and China.
