Jadeite glass is a type of opaque, milky-green glassware. First mass-produced in the United States during the 1930s as a cheerful and durable alternative to expensive jade, it was popularized by brands like McKee, Jeannette, and Anchor Hocking (Fire-King) and remains a highly sought-after collectible today.
The value of Fire-King Jadeite dishes can vary widely, ranging from $5 to over $1,000, which makes collecting them a fun experience for collectors with any budget. Museum quality pieces can sell for $5,000+, but they are practically impossible to find as there were very few made.
💚 It glows green with a UV light. McKee and Jeanette jadeite all have uranium, so they glow bright green with a UV light. These are both depression era jadeite glass. 💚 Some McKee jadeite has a distinct McK marking.
Jadeite Fire King
Unlike the earlier items from McKee and Jeannette, Fire King items do not contain uranium and are a slightly different shade of green. Uranium was removed from glass mixes in the early 1940s due to war efforts. These Fire King items will not fluoresce under UV light.
McKee and Jeannette glass companies produced jadeite in the 1930s and 1940s, featuring creamy, opaque tones that often did include uranium, meaning most pieces from these manufacturers do glow under black light.
Yes, uranium glass is perfectly legal to buy, sell, and own in the United States and most other countries. Because the uranium is tightly bound within the glass matrix and used in very small amounts, it falls under regulatory exemptions.
Jadeite can be worth anywhere from less than $100 to millions of dollars. As one of the world's rarest and most historically prized gemstones, top-tier "Imperial Jadeite" commands prices that exceed even diamonds. Value depends entirely on color, translucency, texture, and treatments.
Generally, vintage jadeite is safe to use for its intended purposes. However, it's important to inspect for any damage or cracks that could compromise its structural integrity. Make sure vintage jadeite items, especially kitchenware, have not been treated with harmful substances like lead-based glazes.
For these people, the maximum estimated dose is 1 to 2% of the average American's annual radiation exposure. This tells us the level of radioactivity in uranium glass is generally considered very low and not harmful under normal handling and use.
Check The Density Of Jade
If you have a piece of real jade, clink it against the stone in question. If it sounds like plastic beads, then the stone in question is probably fake. Both jadeite and nephrite have a very high density (jadeite - 3.3; nephrite - 2.95).
The best jadeite is semitransparent, meaning the text you can read through it would be slightly blurred. Because light penetrates below the surface, semitransparent jadeite has an alluring brilliance. It almost appears to glow, increasing the charm of a lush green or rich lavender hue.
One of my favorite items to collect – both old and new – is jadeite. Its milky glass in the iconic minty green color is appealing and timeless. It's also a color that reminds me of spring.
The jade flashlight test uses a high-powered jeweler’s torch to inspect a gemstone's internal crystal structure, transparency, and authenticity. By shining a strong white, yellow, or UV light directly through the stone, you can reveal hidden fractures, coarse textures, dyes, or treatments commonly found in fake or low-quality jade.
The most valuable vintage and antique glassware ranges from 19th-century French crystal sets and museum-quality Art Nouveau vases to highly specialized, mid-century American studio pieces.
Yes, jadeite does sometimes glow under a black light (UV light), but why it glows depends entirely on what kind of "jadeite" you are talking about.
While the word "jade" is absent from many traditional, older Bible translations (like the KJV, which often translates the original Hebrew word as "jasper"), several modern translations explicitly mention jade to describe precious, highly valued gemstones.
To determine if your jadeite is vintage glassware (like Fire-King or McKee), focus on identifying the manufacturer marks, checking for mold seams, and testing the piece with a black light for uranium content.
The world’s most expensive piece of jadeite is the legendary Hutton-Mdivani Necklace. This iconic Cartier masterpiece features 27 graduated, highly translucent Burmese imperial jadeite beads, and it set a world auction record at Sotheby's Hong Kong by selling for $27.44 million USD.
Larger, unblemished pieces of jade are rarer and, therefore, more valuable. The price per carat can increase exponentially with size for high-quality specimens.
However, as the amounts of uranium used in each piece are typically very low, it is safe to have in your home so long as it is used and handled correctly. Uranium glass is considered to be radioactive, but the level of radioactivity is very low.
The Uranium price today is 84.70.
The title "most radioactive" depends on whether you are looking for an open-air location, an accidental disaster site, or a naturally occurring anomaly.
A 1-carat jadeite price ranges widely from $𝟑𝟎 to over $𝟏𝟎,𝟎𝟎𝟎. Because jadeite value is almost entirely based on color, translucency, and treatment, there is no single set price for a 1-carat stone.
Is real jade cold to the touch? Jade has a cool feeling to the touch and won't heat up even if you rub it against the skin or squeeze it tightly with your palms. Imitation materials are typically warmer because of having plastic or glass that retain heat more easily.
Jadeite is the rarer of the two jades since its interlocked crystalline structure and chemistry produces a tough structure, intense colors and smooth, glassy finishes. Jadeite jade is most often used in jewelry and fits the criteria for fine gemstones because of its beauty, durability and rarity.
