Blue coloured stones

Fourteen famous blue stones

Gems in this rare natural shade are always in great demand for jewellery. People have adorned themselves with blue stones for centuries, but the quality and variety of precious minerals available today are many. Operators specialized in stone analysis evaluate the colour considering hue, tone and saturation. Precious stones often have a secondary shade in addition to a primary one or as translucent rocks. For blue stone, common secondary shades are green and purple. In general, a purer blue hue is desirable, and when a stone moves away from blue it is considered less valuable. However, greenish blue and purplish-blue stones are still quite attractive. Blue sapphires with slight purple hues are still the reference colour. Color Of Precious Stones, Semi-precious Stones & Jewellery

Other gems, such as paraiba tourmaline, most commonly show secondary green hues. Blue shades reach maximum saturation or intensity, in medium-dark tones, about 85%. This is called the gamma limit. Vivid saturation is a mind-blowing colour. Darker tones will appear as ink or steel, while lighter tones may appear washed out or grey. However, beautiful blue stones are found in a wide range of tones, from light, light blue colours to dark and deep colours.

Colour purity

Degrees of purity are much less important in blue-colored stones than in colourless stones. Since colour can mask inclusions this makes them less noticeable. However, it will be best to avoid large inclusions or fractures, as they can certainly make the stone more fragile. For blue gems with lighter tones, a higher degree of purity will improve the appearance of the gemstone. In these cases, it is better to avoid dark inclusions, as they will be immediately noticeable in a light shade stone.

If you are looking for a blue stone for a ring, the following types are the best you can find. Each of these stones has a score of at least 6.5 on the Mohs hardness scale, thus making them scratch-resistant. Better yet, they are less likely to break if they accidentally fall or bump into an object. These gems will withstand daily wear and tear, making them ideal as engagement rings. With regular cleaning, they will also continue to look as good as the day you bought them.

The varieties of blue stones

The 13 famous blue gemstones

When most people think of a blue-colored gemstone, usually the first name that comes to mind is aquamarine, but today a large number of other azure gems are available. Natural blue stones are available in different shades and shades of colours including the milky moonstone gem with blue reflections. Currently, many gems are generally made in the laboratory to enhance colour or to create different colours. Often the blue stone has a different name, this only to create the perception of a higher value. For example, many people think that the Swiss Topaz celestial stone is of Swiss origin while the mines from which this blue gem is extracted are in India and other countries, so when it comes to precious minerals do not be fooled Before buying a stone, think about the exact shade of blue you are interested in and what you will use it for (jewellery, collection, furnishing object).

The hardness of a specific type of gemstone often defines its use. A softer gemstone is probably best suited as a pendant, but not in a ring. You will find that each type of gem has its own unique properties and attractions. It is not surprising that colour is the most important factor in the evaluation of a stone. In fact, in percentage terms, the colour of the gem contributes to about 50% of its final value.

Light blue stones: the importance of carat weight

Weight (in carats), cut and purity directly influence the colours of the blue stones. But as far as beauty is concerned, the question remains highly subjective and, ultimately, depends on the observer. This does not mean that there are no criteria for judging the colour of the stones; On the contrary, they exist, but they should never prevail over personal preference. It no longer surprises anyone that the colour of a gemstone is more attractive, the greater its value. Some people think that the blue colour of the stone symbolizes the sky and the sea and that this means truth, sincerity and inspiration. An ancient legend says that offering an engagement ring with blue stones can bring continuity to married life. It is said that various colours, tints and shades of blue have different meanings. For example, slightly darker blue can often be seen as a sophisticated and innovative colour, while a light hue symbolizes loyalty and credibility.

Green precious stones

11 important green gems

Since ancient times the question: what is the green stone called? The answer was emerald, which has always been synonymous with “green”. However the varieties of valuable gemstones there are so many other stones of green colour, which offer you many alternatives to the classicism of emeralds. Find out how to evaluate the colour and quality of green stones and which gems are the best to wear every day in jewellery. Gemologists evaluate colour by considering hue and saturation. In a green gemstone, the primary shade is logically green, but often the gems also have other shades called secondary. Green stones may have secondary shades of blue or yellow. In general, a pure shade of green is the most desirable (and most expensive). For secondary shades, most people prefer a hint of blue to a more yellowish stone. Yellow-green stones can still be quite attractive but will not reach the maximum price quotes. Green colours are more saturated or intense in medium-dark tones. Darker gems can quickly become too dark to appreciate their colour. Lighter tones, on the other hand, can be lively and bright. In conclusion, green semi-precious stones with the brightest and most saturated colours are the most desirable and expensive.

The clarity in a green stone

Clarity can be an important factor in the overall quality of the hard green stone. Keep in mind that clarity in a gemstone doesn’t simply refer to transparency, but rather to the unique natural imperfections of each mineral. In general, these are less noticeable in a darker stones than in lighter ones. However, avoid stones with large inclusions or fractures, as they may be more prone to breaking. In addition, large or dark imperfections in the centre of the gem are easily noticed, so avoid gems with this type of imperfections. However, if you are looking for a large stone of this colour for a ring to wear every day, the following are the best options; each of these has at least a hardness of 6.5-7 on the Mohs scale and this makes them resistant to scratches and accidental impacts. These green hard stones will withstand daily use, making them ideal for your jewellery. So remember to clean your green stones regularly and they will continue to shine like the day you bought them.

The main characteristics of a precious stone

Minerals and gems can be identified by various properties. Characteristics commonly used to identify minerals include colour, hardness, crystal shape, texture, cleavage, density (or specific gravity), and magnetism. Hardness refers to the resistance of a substance to scratch. The Mohs hardness scale (named after the Austrian mineralogist Friedrich Mohs) lists 10 reference minerals arranged in ascending order of hardness. Note that this is a relative hardness scale: talc with value =1; a diamond with value =10. Diamond is actually over four hundred times harder than talc.

Features of stones and minerals

Splitting is defined as the breakdown of a mineral along planes of atomic weakness. Specific gravity is the ratio of the mass of a given volume of a mineral to the mass of an equal volume of water. Specific gravity refers to the feeling of heaviness of a mineral (density). Magnetism is a property of minerals that contain iron. Below is a list with the images and names of most of the precious stones known so far. Because the world of Gems and Minerals is constantly evolving and, almost every year new Gems are discovered, often rare, new gem names are often assigned by the discoverers themselves. Many precious minerals form beautiful crystals, but the most valuable is found in the Olympus of the most precious stones.

Stone processing

Uncut stones often look like quite ordinary rocks. It is only when they are cut and polished that they get the brilliance and shine that give them their value. Historically, gems have been divided into precious and semi-precious classes. There are a number of semi-precious gems, many quite beautiful, but diamonds, rubies, sapphires and emeralds continue to qualify as top-of-the-value stones. At one time amethyst was also considered a gem of high commercial value, but later large reserves were found in Brazil and its value today has fallen slightly. So now we will try to guide you through the fascinating world of minerals, offering you a collection of information and not only under the aspect of mineralogy.

Classification of stones and minerals by colour

In mineralogy, colour is one of the primary diagnostic properties of natural compounds, of great importance in geological prospecting for the identification of minerals. The colour of gems and semiprecious stones is one of their main qualitative characteristics. A distinction is made between the colour of minerals in individual crystals and in ore agglomerates, the colour of minerals in transparent thin sections (under a microscope), the colour of minerals in smooth sections (in reflected light) and the colour of fine powder of hard stone. A comparative assessment is usually used to describe the colour of stones and minerals.

Precious minerals and colour

The colour of the mineral is compared to the colour of some commonly known object or substance (indigo blue, apple green, lemon yellow and blood red) or to “standard colour” minerals, such as vermilion red and emerald green. The colours of metals or alloys are also used as a standard to describe the colour of precious minerals: tin white (arsenopyrite), steel grey (molybdenite), brass-yellow (chalcopyrite) and copper red (native copper). Methods for objective colour assessment of minerals and gems using standard colourimetric characteristics are being developed.

Many minerals have the property of showing different colours in different crystallographic directions, especially under polarized light or changing their colour properties according to the colour temperature of the source that illuminates them. The study of the colour of crystals provides information about the crystal chemical and genetic characteristics of precious stones and is useful in the synthesis of high-quality precious mineral analogues of natural gemstones.

Types of stones and minerals

There are over 3,000 different types of minerals, but only about 50 are commonly used as high-value stones in jewellery. What are the peculiarities that make a hard stone as precious? In general, a precious stone is a beautiful, rare and durable stone (resistant to abrasion, fracture and chemical reactions). Some minerals can be very beautiful, but they can be too soft and scratch easily. Others are too common and have a defined status in semi-valuable jargon. Most gems have good hardness (above 5 on the Mohs scale) and a high refractive index (the higher the refractive index, the greater the brilliance).

All stones recognized as precious have some inclusions and never reach perfection; even the seemingly perfect diamond. Most gemstones are silicates which can be very stable and hard minerals. Some gems are oxides and only one gem, a diamond, is composed of a single element, carbon. In conclusion, we can observe that there are also many stones that are not true minerals, but that are types of materials chemically but finally recognized as such.
