Rare and Exquisite Gemstones: Black Opal and Poudretteite

Jadeite: A Precious Stone of Rarity and


Jade, a mineral of two types of different silicates, jadeite and nephrite, is commonly known as the national stone of China. The mineral has been used for centuries as a decorative object, a symbol of power and status, and as a protective charm.

Jadeite, is the more elusive and rarer variety of jade, and for many jewelry enthusiasts, it is the epitome of gemstone luxury. In this article, we will explore two subtopics of jadeite – rarity and valuation, and value.

Rarity and Valuation

Jadeite, unlike other gemstones, is only found in a few deposits located in northern Myanmar. The mineral is extracted from the mines in blocks of rocks, which makes it challenging to source.

As a result, jadeite is a highly elusive stone, and its rarity is the driving force behind its valuation. Jadeite has a distinctive green color, which is the result of chromium or iron impurities.

The intensity and saturation of the green color determine the value of the jadeite. The most sought-after jadeites are those with a vivid green color, with a translucent appearance, and no cracks or inclusions.

The color, transparency, tone, and texture of the mineral make it one of the most valuable gemstones in the world. In 2016, a jadeite necklace designed by renowned jewelry designer Edmond Chin, fetched a staggering $57 million.

The necklace, known as the “Hutton-Mdivani Jadeite Necklace,” was sold at a Hong Kong auction house, and it features 27 translucent green jadeite beads of exceptional quality. The necklace highlights the rarity and value of jadeite.

Burma is the primary source of jadeite, and the country’s government regulates the mining and export of the mineral. The Burmese government requires all jadeite sales to be done through government-controlled markets, which allows them to keep track of the number and quality of jadeite being sold.

However, the restrictions haven’t entirely deterred illegal mining and sales of the mineral. Jadeite sold in the market can cost anywhere from a few hundred dollars to millions of dollars.

In 2014, a Burmese farmer found a single block of jadeite that weighed more than two tons. The block was sold for $170 million, and it is believed to be the most significant piece of jadeite ever found.


The value of jadeite is determined by several factors, including color, transparency, texture, and size. Jadeites with a vivid green color, a translucent appearance, a smooth texture, and no inclusions generally command a higher price.

The size of the jadeite also affects its value since larger pieces are more challenging to find and are rarer. Jadeite is commonly used in jewelry, and the value of jadeite jewelry reflects the value of the mineral.

Jadeite jewelry can range from delicate bracelets to intricate necklaces and earrings. The value of jadeite jewelry is influenced by the quality and quantity of the jadeite used, the craftsmanship, and the design of the piece.

Apart from being used in jewelry, jadeite is also used in carvings. The intricate and delicate carvings utilize the unique properties of jadeite, and the value of the carvings is also dependent on the quality and rarity of the mineral.

Historically, jade carvings depict religious and mythical figures, and these carvings are highly valued by collectors and enthusiasts. In conclusion, jadeite, the rarer and more elusive variety of jade, is a valuable mineral.

Its rarity and unique qualities make it highly sought-after by collectors, enthusiasts, and jewelry designers. Its green color, transparency, texture, and size are the primary determinants of its value.

Although it is only found in a few deposits in Burma, it has captured the attention of the world and is now a globally recognized symbol of luxury.

Royal Demantoid and Blue Garnet – Two Unique and Valuable Gemstones

Gemstones have been a symbol of beauty and luxury for centuries. From diamonds to pearls, gemstones have captured the imagination of people around the world.

The traditional gemstones are well-known and heavily marketed, but there are some lesser-known gemstones that are just as beautiful and valuable, if not more so. In this article, we will explore two such gemstones, Royal Demantoid and Blue Garnet.

Appearance and Origin: Royal Demantoid

The Royal Demantoid is a gemstone that belongs to the garnet family. It is known for its deep green color, which is often tinged with a yellow tint.

The stone’s intricate and dense growth patterns give it a unique brilliance and fire that makes it stand out from other green gemstones. Royal Demantoids are mainly found in Russia, in the Ural Mountains.

The name “demantoid” comes from the Dutch word for diamond, “demant.” The gemstone was first discovered in Russia in the early 1800s and was then mistaken for green diamonds because of its brilliance and fire. The Royal Demantoid’s rarity and unique characteristics have made it popular among jewelers worldwide.

The stone is often cut in various shapes, such as round, cushion, and rectangular, and it is often used as solitaire or in combination with other gemstones in jewelry.

Value: Royal Demantoid

The Royal Demantoid is a valuable gemstone, with a price tag that ranges from $2,000 per carat to over $10,000 per carat. The stone’s value depends on several factors, such as the color, clarity, size, and cut of the gemstone.

A top-quality Royal Demantoid that has a deep green color and no visible inclusions can fetch a very high price. Smaller stones with yellow or brownish tints are less valuable, whereas larger stones with the right color saturation and clarity command a higher price.

Appearance and Origin: Blue Garnet

The Blue Garnet is a rare gemstone that resembles the sapphire with a greenish tint. The color of Blue Garnet ranges from blue-green to greenish-blue, and its unique coloration is due to the presence of Vanadium and Chromium.

This gemstone is mainly found in Madagascar, where the discovery of the blue garnet caused a great sensation in the gemstone market. Interestingly, the blue garnet wasn’t discovered until the 1990s when a group of local miners found it in the Androy district of Madagascar.

The gemstone’s rarity made it an instant hit among gemstone enthusiasts, collectors, and jewelers alike.

Value: Blue Garnet

The Blue Garnet is a valuable gemstone, and its worth can exceed $2,000 per carat. The value of Blue Garnet depends on the color, clarity, and size of the gemstone.

It is important to note that the vast majority of blue garnets are small, with sizes ranging from 0.1 to 0.5 carats. The highest quality Blue Garnets are those that exhibit a deep blue-green color, have a transparent appearance, and no visible inclusions.

This quality garnet can only be found in the most exclusive markets and can fetch an extremely high price. Garnets that have a lighter or paler color and visible inclusions are less valuable.

In conclusion, Royal Demantoid and Blue Garnet are rare and valuable gemstones that are sought-after by collectors and enthusiasts around the world. Their unique and distinctive characteristics make them stand out from other gemstones.

The rarity of these gems and their exquisite attributes make them a treasure to behold and a worthwhile addition to any gemstone collection.

Black Opal and Poudretteite – Exquisite and Rare Gemstones

Gemstones are objects of beauty, and some of the most valuable and rare gemstones are unsung heroes in the jewelry industry. Some of these gemstones are not as well-known as diamonds or rubies, but they are highly prized by collectors and enthusiasts.

In this article, we will explore two such gemstones, Black Opal and Poudretteite. Appearance and Rarity: Black Opal

Black Opal is a gemstone that is well-known for its colorful play-of-color.

The stone is mainly found in Australia, with the most significant deposits situated in the Australian state of New South Wales. Black Opal gets its name from the dark background color of the stone that accentuates the rich, bright colors of the rainbow displayed on its surface.

Black Opals are one of the most valuable and rare types of opals. Their unique characteristics make them highly sought after by collectors and enthusiasts worldwide.

The rarity of Black Opals is mainly due to the conditions that are required for their formation, as they require hot, dry desert climates to come into being. Black Opals are admired for their striking play-of-colors that span the spectrum.

They are very different from the more common Opal varieties, with much more intense and deep colors. The complexity of their colors, combined with the rarity and natural beauty, makes them one of the most sought-after opals in the world.

Black Opals are a valuable gemstone that can range in price from $1,000 to over $10,000 per carat, and the value is dependent on several factors. The most significant determinants of Black Opal’s value include its color, clarity, size, and quality of the play-of-color.

Appearance and Rarity: Poudretteite

Poudretteite is a comparatively new and rare gemstone that was discovered in 1987 in Quebec, Canada. The stone is known for its delicate and sophisticated pink shades, which range from soft-pink to purplish-pink.

Poudretteite is produced at Mont Saint-Hilaire, near Montreal, and is a byproduct from pegmatite minerals. Poudretteite is often compared to Pink Sapphire due to the similarity in their color.

However, the amount of Poudretteite is far less than Pink Sapphire, making it an even more valuable stone that is highly prized by collectors and enthusiasts. Poudretteite has an average hardness of around 5 to 6 on the Mohs scale, which makes it relatively soft and unsuitable for daily-wear rings.

This makes it challenging to set into jewelry designs and very expensive to produce pieces.

Value: Poudretteite

Poudretteite is a rare and valuable gemstone that can reach up to $3,000 per carat. The value of Poudretteite depends on the color, clarity, and size of the gemstone.

The most valuable Poudretteite is one that exhibits a rich and saturated pink color with a transparent appearance and no visible inclusions. Due to its rarity, Poudretteite is mainly found in small sizes, such as less than a carat.

Larger pieces are exceedingly rare and, by extension, more expensive. In conclusion, Black Opal and Poudretteite are two of the rarest and most unique gemstones in the world.
