Precious and semiprecious Gemstones deep blue

A number of gemstones occur in blue colors with different color depth and hue. A few gems are found with nearly the blue depths of the earth from space. The only gem I think is the closest to the color you suggested is Lapis Lazuli. Since many commercially available semi-precious gems are dyed and otherwise treated to create colors of the stone, I will first describe stones that are found naturally in the deep blue.

Lapis Lazuli is a gem to use since ancient times. Just think 'the blues used by the Egyptians who used both ancien lapis and blue glass ornament. It is a precious stone "massive", means that it is in crystals, but rather made up of many small particles glued together.

The best blue Deep Purple comes from Afghanistan and is very close to the color of the oceans. Recently, a module named "lapis" denim has been offered, but this is the blue-gray material that has been rejected because of poor quality years ago. Some types of lighter and more gray lapis come from Chile

"Gem grade" lapis is not a precious stone, but will not be cheap. Gem grade is richer in color, generally without pyrite (Fools Gold) projection and pure color throughout the gemstone cutting. Some people consider pure dark blue lapis without the sparkles of pyrite the best while others give value of pure stone with a dark blue uniform and eye-pleasing display of pyrite.

The pyrite in lapis gives a golden gleam of every speck of this fools gold. Going a bit 'down quality, lapis with the pure blue color may have white streaks. These stones will look like your picture suggested by the clouds added to the blue.

The more the lapis varies from dark blue pure lower the value becomes. The so-called "denim lapis" is a marketing term used to sell this stone. Personally, although much lower price than higher grades, the mix of good material "Denim" works well in jewelry is less expensive and quite appealing. The material is colored something like stone-washed blue jeans and I suppose that is where the name "denim lapis" originated. "Sodalite" is close to the color of lapis but generally more blackish with variations with white material in the rock.

"Lazulite" is a rare mineral that forms crystals of a deep blue depths. This is not a semi-precious stone, and is of greatest interest to mineral collectors. Lazulite the mineral giving Lapis its rich color. Another mineral collectors choice is "azurite", a mineral that is a deep blue semi-precious stone, but it adds color to a little 'gems mixed green and shades of blues as "Eilat Stone", a stone soft enough sometimes sold as semi-precious. The stones of which are the main show the dark blue color you choose. For use in jewelry, only Lapis Lazuli and Sodalite qualify in the range of colors.

To see more of lapis or any stone of which this response, simply search the Web. To the best stones, I suggest you say something like "lapis gem grade". Stones cut like opals, lapis, tiger eye, black onyx, etc., are called "cabochons". Cabochon cut stones are flat or domed, unlike faceted stones such as diamonds, sapphires, blue topaz, etc. As a note, some sites call stones "gem grade" when in fact the stones are of lower quality. Also, be aware that many cabochons stones are dyed and treated to make it look kind of down material like natural stone most precious.

Other blue stones like "Agate" will sometimes show blue but the majority is more than a pale blue to medium blue. Any likely have dyed dark blue. "Tanzanite" is a multi-faceted jewel, cut crystal. The color varies from pale blue to electric blue. This is not inexpensive in better grades. "Lolitas" is a multi-faceted jewel that is not very expensive, but it shows a deep blue purple stone well cut. The color varies depending on which direction you look through the gem.

"Spinel" is mostly thought of as a stone "class rings" and a lot of artificial joint is used in those rings. Spinel is a natural stone rarely, but a deep blue color is beautiful. Spinel may also be red. "Tourmaline" is a multifaceted gem and colors are all over the rainbow.

A kind of blue is called "Indicolite" pale blue and can be very, very dark. Other blue stones believed to have precious gems are too light or blue to meet the sea view from space: blue topaz (treated to get the dark blue), Aquamarine (pale blue), turquoise and blue zircon (heat-treated to make blue).

A note on semi-precious and precious stones: Some of the "gems" like sapphire may cost less than a gem quality lapis or spinel, for example. The price all depends on the quality of the particular stone. Overall, the level of quality for quality, precious gems like diamond, sapphire and ruby ​​will be much more expensive than other stones. A semi-precious stone can vary a few dollars to several hundreds or thousands of dollars depending on quality, for example, "Opal".

Some of the semi-precious stones like "Agate" will command higher prices for the stones very beautiful, but also compete more closely with the precious gems. What we like is all in the eyes of the wearer! Lapis, like the ocean seen from space is a lovely gem .......
