White Diamond Ring: Many people call transparent or colourless diamonds white, not even suspecting the existence of true white faceted diamonds. Impurities create a snow haze with various shades in white diamonds. You can look at such a stone for a long time, finding new forms in it. Natural white diamonds, like transparent ones, look very beautiful on a dark background. Jewellery with such stones looks elegant.

Black Diamond Ring: The name “carbonado” comes from the word “carbo” – coal. This term was introduced when these minerals were discovered in Brazil. Carbonado is a type of cubic black diamond. These are fine-grained, porous aggregates of black, grey or even dark green colours. Black diamonds are synthesized on an industrial scale at a pressure. Nickel is used as a catalyst. Until recently, black diamonds were considered exclusively technical.

Yellow Diamond Ring: Among fancy colour diamonds, yellow diamonds are relatively common. And if even a faint yellow shade is undesirable for colourless diamonds and reduces the price of a gemstone, then for fancy diamonds the price of a carat will increase depending on the intensity of the yellow colour. The colour scheme of “yellow” diamonds is quite wide, stones are found from “light yellow” to “vivid yellow” shades.

Pink Diamond Ring: The pink diamond is a type of diamond, the source of the pink colour which is explained by the enormous additional pressure that these diamonds undergo during their formation. Pink diamonds are a subcategory of diamonds called fancy colour diamonds. Pink diamonds range from flawless to inclusive, like white diamonds. Throughout the history of gem mining, several pink diamonds have been discovered with impeccable internal purity.

Emerald Rings

Emerald Ring: Emerald is a mineral, a gem of a beryl group. It also belongs to the first group of minerals. In nature, it is rarely possible to find a completely transparent gem. And such emeralds are valued very highly. Currently, the largest number of all emeralds is mined in Colombia. The main quality criteria for an emerald are its colour, and then transparency. An ideal emerald is a transparent gemstone of evenly distributed saturated colour.

Ruby Rings

Ruby Ring: Ruby is a mineral, a type of corundum, which belongs to the class of oxides, trigonal Synonym. The ruby hardness is 9 on the Mohs scale. In hardness, it is second only to diamond. The colours of this gemstone range from bright red to dark red and even purple-red. With this, blue corundum is sapphire.

Blue Sapphire Rings

Blue Sapphire Ring: Sapphire is a gem of various shades, one of the varieties of corundum. In mineralogy, sapphires of exclusively blue colour are called corundum, in the jewellery industry – any colours except lilac-red. The blue sapphire owes its deep blue colour to the presence of titanium and iron compounds in the molecular structure. It should be also mentioned such a type of gem as star sapphire, as they are quite rare and highly valued.

Pink Sapphire Ring

Pink Sapphire Ring: Pink sapphire is considered the rarest and most expensive. In its physical properties, it does not differ from the rest. The palette of tones starts from the delicate colour of a tea rose to a bright, almost purple. The price depends on the purity of the stone and its shade. The pink sapphire is more transparent and saturated in colour, the more expensive it is. In turn, lighter tones are sometimes more expensive than the brightest gems.

Yellow Sapphire Rings

Yellow Sapphire Ring: Yellow sapphire is one of the most popular transparent noble varieties of jewellery-grade corundum mineral. The properties of the stone, not counting the colour, are the same as those of blue sapphire and ruby. The colour palette is limited to golden hues: from light, pastel yellowish to saturated yellow-orange. This colour is mainly due to an admixture of iron.

Tanzanite Ring: Tanzanite is an extremely rare and expensive stone that belongs to the silicate group. The official name of the mineral is zoisite. The colour of tanzanite varies from sapphire blue to deep purple. Existing yellowish-brown specimens are not popular in the jewellery industry. Also, tanzanite has an alexandrite effect and changes colour depending on lighting and even the viewing angle.

Morganite Ring

Morganite Ring: Morganite is a rare variety of beryl mineral with an admixture of manganese. The colour palette of morganite varies from pale pink to red-violet. Sometimes the mineral may have a yellow or peach colour. The more pink the stone is, the more expensive it is. Orange shades reduce the price of the sample. Due to its optical properties, stones look great in jewellery.

Peridot Ring

Peridot Ring: Peridot is a green mineral that is often called chrysolite in jewellery practice. The physical properties of peridot differ little from the properties of quartz. However, the relatively high price of peridot does not allow the use of a mineral as widely as regular quartz. Peridot is traditionally used for jewellery, while quartz is a popular industrial material. Mineralogical museums of the world are full of interesting examples of peridot.

Topaz Ring: Topaz is a semiprecious transparent stone, a mineral belonging to the class of silicates. Topaz is the hardest mineral in its class. It has a strong glass lustre with a pearly shimmer. Topaz crystal can have a variety of colours: there are stones of blue shades, blue topaz, pink topaz. However, with prolonged exposure to sunlight, the stones lose their colour, so the minerals found near the surface of the earth are usually almost colourless.

Amethyst Rings

Amethyst Ring: Amethyst is the most valuable variety of quartz, known since ancient Egypt. The colour of amethyst can be very saturated and depends on the impurities of iron in the mineral. The stone may lose colour under the influence of high temperatures: when heated, the amethyst becomes very pale, but can again return colour when it cools, and at 300-500 ° C the amethyst becomes colourless forever.

Tourmaline Ring: Tourmaline is one of the most famous minerals, including a collection of the most beautiful and most valuable jewellery stones, such as rubellites and paraiba tourmaline. The chemical formula of tourmaline is complex, there are many variations. Each of them has its own type of tourmaline, of which there are more than a dozen. Basis – aluminium silicate and boron. The rest of the composition can be very diverse. Mohs stone hardness is 7.5. Tourmaline is sparkling, often transparent, however, muddy specimens are also found.

Aquamarine Ring: Aquamarine is a solid mineral with a glass sheen and belongs to the beryl family, best known for its precious emeralds. The colour palette is from deep blue to almost transparent pale turquoise, which is caused by impurities of iron. Sometimes among aquamarine, there are specimens with the effect of asterism or “cat’s eye”. Such specimens are extremely rare and of particular value.

Citrine Ring: Citrine is a type of quartz mineral that differs from ordinary quartz only in colour. A relatively inexpensive semiprecious stone. The colour of the stone varies. It is a pale yellow, juicy lemon, bright honey. Colour depends on impurities, ferric iron, tetravalent silicon and trivalent aluminium. This mineral is easy to process, it is durable, hard, scratches the glass. Natural citrines may have cloudy zones, inclusions of opaque quartz, and cracks.

9 Karat White Gold: To obtain white, silver and palladium are added to jewellery alloys of 9-carat white gold, and less often nickel. Then the jewellery is covered with rhodium. Such jewellery gets a special brilliance and can compete with 18-carat gold. 9-carat white gold is the most affordable jewellery option. The cost of such gold may be higher because often jewellery made of 9 carats white gold is inlaid with precious accents.

18 Karat White Gold: 18 carat white gold, which is more expensive, has a high purity equal to 75% of the gold content. White gold is specially mixed with metals that make the alloy look whiter. It is also worth noting that white gold is plated with rhodium, which gives the jewellery a special shine.

9 Karat Yellow Gold: 9-carat yellow gold contains 37.5% pure gold in the alloy. The colour of gold is affected by ligature. For yellow gold, it is zinc, copper and silver. Usually, 9-carat yellow gold has a rather dull colour. Products from this material have properties that are not characteristic of metal products: first of all, they are light and hard. In this regard, this material is widely used in the inlay of everyday things of constant use.

18 Karat Yellow Gold: 18-carat yellow gold includes 75% pure gold in the alloy. 18-carat alloys contain more gold, and therefore are cleaner and softer. That is why such jewellery, as a rule, wears out faster. The ligature in yellow metal products may contain mixtures of copper, nickel, silver, or palladium. It is because of the ligature additives that the products come in various shades.

Platinum: Platinum is a chemical element, a precious shiny noble metal of silver-white colour. Up to a third of all platinum produced is used in the jewellery industry. Platinum is one of the rarest metals: its average content in the earth’s crust is 5⋅10−7% by weight. Even the so-called native platinum is an alloy containing from 75 to 92 % platinum, up to 20 % iron, and other metals.

Palladium: This element belongs to transition metals and two noble metals of the platinum group (light platinoids). The simple substance palladium under normal conditions is a silver-white ductile metal. This precious metal exists in nature in the form of compounds: according to scientists, palladium is part of about 30 minerals. In a native form, the element is also found, but very rarely.

18 Karat Rose Gold: To achieve a saturated colour of jewellery of 18 carats rose gold, a ligature is added to the composition where copper and zinc are present. Thanks to these materials, rose gold is obtained, which, in addition to appearance, receives improved characteristics. Products from it look luxurious and noble.

Silver: Silver is a malleable, ductile noble metal of grey-white colour, which is easy to process. A certain part of noble and non-ferrous metals is found in nature in a native form. The facts of finding not just large, but huge silver nuggets are known and documented. Silver is cheaper than platinum and gold, but not inferior to them in elegance and beauty.
