World of Blue Gemstones

Blue gemstones have been revered for their captivating beauty and symbolic significance throughout history. From the deep, oceanic blues to the delicate, sky-like hues, blue gemstones encompass a wide range of shades that evoke feelings of tranquility, mystery, and sophistication. In this article, we will embark on a journey through the mesmerizing world of blue gemstones, exploring their characteristics, origins, symbolism, and popular uses.

The Spectrum of Blues

Blue gemstones come in a vast array of shades, each with its unique charm and character. Some of the most coveted blue gemstones include

1.Blue Diamond

Blue diamonds are considered one of the rarest and most expensive substances on our planet. This coloration is usually not bright and often has obvious shades in gray and green tones.

According to the GIA classification, blue diamonds are divided into the following colors with shades: Blue, Greyish Blue, Greyish Greenish Blue, Greyish Violetish Blue, Greenish Blue, Violetish Blue, Grey-Blue, Green-Blue. The intensity gradations are as follows: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark. The most expensive color is Fancy Vivid Blue.

When searching for custom blue diamonds, we study current market offers from reliable suppliers and offer only the most attractive specimens with GIA certificates that confirm the suitability of the color. It is worth bearing in mind that the weight of blue diamonds is usually represented by specimens up to 1 carat.


Known for its rich, royal blue color, sapphire is one of the most popular blue gemstones. It symbolizes loyalty, wisdom, and nobility. The most famous sapphire engagement ring is the one worn by Princess Diana, which now adorns the hand of Catherine, the Duchess of Cambridge.

In addition to the royal blue color, there are also light blue shades of sapphires: Pastel Blue and Light Blue.

Violet and greenish shades, as well as obvious zoning on the side of the stone's ground, reduce the price. Sapphires are often heat-treated. This sometimes removes the hues and also makes light blue sapphires richer and cleaner. 

 Blue sapphire gemstone can be an excellent investment.

3.Paraiba Tourmaline

Paraiba blue tourmaline is the most valuable variety from the tourmaline mineral group. They were first found in the state of Paraiba in Brazil, after which they were named. They appeared on the world market in 1988. Paraiba tourmalines are famous for their rare neon blue color. Scientists attribute their coloring to the content of copper impurities. Violet and green tints lower the price, so heat treatment is often used to eliminate them. The main colors of these tourmalines are: blue; greenish-blue; greenish-blue. Intensity: Medium; intense; strong; intense; deep.

These days, most Paraiba tourmalines come for sale from deposits in Mozambique. The color of stones from there usually lies in the light greenish-blue range. Specimens from Nigeria have also been discovered recently, but they are rarely found on sale. Brazilian specimens are the most expensive and are of investment interest. They are characterized by the brightest coloration. And only among them we single out the darkest colored gradation "Deep Blue". Unfortunately, Brazilian specimens are rarely larger than 1-2 carats. A good quality Paraiba tourmaline is a stone that is sure to impress.

4.Blue spinel

 Blue spinel is one of the rarest spinels. The most expensive is Vietnamese cobalt spinel, which has a unique neon blue color. Usually, such spinels are rarely cut larger than half a carat. Most blue spinels, however, are not as bright, are colored with iron impurities and can reach larger sizes. In addition to Vietnam, blue spinels come from Sri Lanka, Burma, and Tanzania. The main shades of blue spinel are: violet-blue; blue; and slightly greenish-blue.

An important advantage of spinel is that it is extremely rare to be refined. It is similar to sapphires in its properties and can be a great alternative to them.  Blue spinel is a stone that will be appreciated by connoisseurs.

5.Blue opal

Blue opal is a stone that does not occur very often. In the best specimens, a play of color in the form of bright multicolored shimmering spots can be seen against the background of the base color.  The main patterns are: "honeycomb" - opalescence is represented by cells in the form of bee honeycombs; "pinfire" - many small multicolored dots; "harlequin" - the rarest type, in which the pattern of colored spots resembles the costume of a harlequin.

In the most expensive specimens of blue opal, bright spots of the red-orange range should be observed. In general, the more large multicolored spots in the stone, the higher it is valued. There are opals without color play. Such specimens come, for example, from Peru.  In this way, blue, greenish-blue and violet-blue primary colors are distinguished. 

Opals are very beautiful and each specimen is unique.

6.Blue aquamarine

Aquamarine is a variety of blue-colored beryl. The name of this "semi-precious" stone is translated from the Latin "aqua marina" as "sea water". The coloring of aquamarines is often very light. It is best seen in large stones. The top aquamarine has a deep blue color called "Santa Maria". Aquamarines are usually free of inclusions and cracks. Read more about aquamarines in our article.

7. Blue topaz

Some of the most popular stones in jewelry are blue topazes. Stones acquire shades of blue color as a result of irradiation of colorless and brownish topazes. In some cases, this is followed by heat treatment.

In commerce, 3 types of blue topaz are distinguished: "Sky Blue" - light; "Swiss Blue" - medium; "London Blue" - deep color.

The price of these topazes is not high and it almost does not increase with increasing weight. From the advantages it is also worth noting that even in large size they usually do not contain any inclusions. Blue topaz is a stone that can be worn every day.
