Although there are gemstones in all colors, in some cases there are rarer colors that are difficult to find and therefore are more valuable and attractive when used in jewelry pieces. Without a doubt, we are talking about gemstones that take on greater value when they are part of a collection or a beautiful statement, perhaps in an engagement ring, wedding ring or in a beautiful necklace.
However, these are gems that in most cases are unattainable. But what colors are the rarest and most unattainable in the world of jewelry? This is surely a question that many have asked themselves and possibly you too. So we invite you to discover it below.
red diamonds
Among the rarest colors in gemstones, red is certainly one of the rarest, especially if it is a pure, unshaded red. Although there are some gemstones that exhibit this beautiful color in diamonds, it is even more rare to find it.
That scarcity is something that makes them the most valued stone, especially since there are barely 30 natural red diamonds in the world. Which were found mainly in Africa, Australia and Brazil, and are currently in the hands of true collectors.
While artificially colored red diamonds are easy to buy, buying red diamonds larger than a half carat is nearly impossible. Since most of the specimens found do not exceed this size. As for the color of these diamonds, for a long time it was thought that this was due to impurities. But it was discovered that they are actually created by an atomic anomaly called «plastic malformation», which makes them even more particular.
A detail in its favor and that gives it an unparalleled beauty is that red diamonds become more dynamic than rubies, and they look better when they are under sunlight. To get an idea of how valuable these diamonds are, a red diamond known as Moussaieff sold for $8 million in 2011. This is so far the largest red diamond in the world.
Orange Pink Sapphires
The orangey pink of sapphires is one of the rarest colors in the gemstone world. Since it is only found in those known as Padparadscha sapphires. Which are beautiful gemstones only found in Sri Lanka, Vietnam and Tanzania. However, to qualify as a Padparadscha, a sapphire must fall into an exceptionally narrow range of colors, making true Padparadschas highly desirable among jewelers and collectors.
purple diamonds
Second in rarity only to red diamonds, purple diamonds are an incredibly unique stone. Due to their versatility and rarity, purple diamonds are a popular choice in high-end jewelry. The more intense the shade of purple, the rarer the stone. As with red diamonds, it is unusual to find purple diamonds in larger carats, especially with any sort of commendable clarity.
amber blue
Found in the Dominican Republic, blue amber is a little-known variety of amber. Although significantly more affordable than other rare gemstone varieties, there is something simply irresistible about blue amber. Appearing like common amber under artificial light, blue amber glows a deep shade of blue under natural sunlight and turns a brilliant cerulean hue under ultraviolet light.
That said, it is not difficult to understand why it is one of the rarest and most appreciated colors in this type of gemstone.
pink diamonds
As with their red and purple counterparts, pink diamonds are a rare find. Although somewhat more common in smaller varieties, large, clear pink diamonds are highly desirable. Stunning rose gold settings, pink diamonds are becoming a popular choice in high-end engagement rings. When shopping for your pink diamond, beware of offers that seem too good to be true, as artificially colored pink diamonds are extremely common.
pure green emeralds
While all emeralds are green, pure green emeralds are rare, particularly in vivid hues and without inclusions. Among the most attractive gemstones to behold, emeralds in their most valuable form are remarkably eye-catching. Almost impossible to confuse with other gemstones, emeralds are a must have for any passionate jewelry collector. When shopping for emeralds, avoid stones with strong yellow or bluish hues. The perfect emerald should be a bright, light green with no hint of cloudiness or glassiness.
black opal
Although most opals are usually a creamy white color. Black opal exhibits one of the rarest colors in this gemstone family, making it a stunning gemstone. Since it is interwoven with different colors and shades so that no two pieces are the same.
The darker versions look like stones that have captured a cloudy midnight storm lit by a full moon. The most colorful versions begin to look like a clear, colorful night sky, as if entire stars and galaxies have been captured in stone. Few stones inspire the imagination so much at a glance.
Black opal is so rare that 97% of the world’s supply is produced in Australia. Specifically in the mines located in the Lightning Ridge area of New Wales in South Australia. In this type of stone, the darker the black opal and the brighter its inclusions, the higher its value.
The aurora australis is the most expensive black opal in the world. This stone sold in 2005 had 180 carats and was valued at 763,000 US dollars.
Red Beryl
Also known as red emerald or bixbite, what makes this stone especially valuable is its color. Since common beryls are generally colorless originally, this type of beryl becomes highly appreciated. But, it is one of the rarest colors, as there is only one red beryl crystal for every 150,000 diamonds. Being difficult to find beryls larger than 2 or 3 carats. It is found almost exclusively in Utah, United States and its value can reach more than 10,000 dollars per carat.
