20 18 all say that ultraviolet rays are difficult to control. How to use purple "gems"?

I believe that the color of 20 18 announced by PANTONE some time ago-ultraviolet color UITRA VIOLET has swept everyone's circle of friends! After reading a lot about UITRA VIOLET, today I want to go on to introduce those little-known purple gems. In fact, it may be a bit inaccurate to say that it is a gem, because most of the things to be introduced next are semi-precious stones or jade (hereinafter referred to as gems or jade), and the high-quality ones all have the charm of top-class gems.

Sugilit

Millennium stone

Hardness: Mohs hardness is 5.5-6.5.

Specific gravity: 2.75-2.80

Refractive index: 1.66- 1.68

Crystal form: hexagonal system

Characteristics: sphalerite is a rare mineral, its color is mainly light pink to deep purple, and some sphalerite is dark blue. Its color is glass to waxy luster, translucent to opaque, and most sphalerite has irregular spots, showing several different colors.

High-grade jewelry series

Material: platinum, diamond, amphibole.

Sugiyama is a young jade facing the market, because it was discovered by Japanese lithologist Sugiyama Kenichi in 1944, and then entered the market, and now it has become a relatively common jade. Although sphalerite is not a gem, its unique color characteristics have attracted the attention of jewelry designers. For example, in 2009, sugilite was used in the Reines et Rois Haute Joaillerie series designed by Dior's chief senior jewelry designer Victoire de Castellane.

High-grade jewelry series

Material: platinum, diamond, amphibole.

In this series, Victoire designed ten pairs of brooches and rings for the king and queen. We can see that sugilite is carved into the shape of a skull and placed under a platinum crown full of diamonds, which is gorgeous and ironic. Rococo-style shape design with different shapes of diamond inlay, coupled with the skeleton-like main stone carved from rare gems, makes each work reveal a strong sense of luxury, and the design of skull is in sharp contrast with the precious metals and gems that never decay. Because sphalerite is a kind of ore suitable for carving, high-quality sphalerite is often carved into different forms.

mauve jadeite

Violet jade is actually a kind of color in jade, and violets with pure color and good water head are extremely rare. Jade and jade may still be very traditional images that young people don't like, as shown above.

However, the color of violet is more special. After carving the jadeite, craftsmen used different materials to design it, which made the jadeite which looked antique undergo a gorgeous transformation.

Victoria amethyst relief brooch

Material: gold, emerald, enamel, amethyst.

Amethyst should be the most familiar purple gem, which is widely used in all kinds of jewelry. I believe many people have bought amethyst bracelets because it is said that amethyst can increase popularity, drive away bad luck and protect love. But amethyst is not only used for beaded jewelry, but also high-quality amethyst is carved as a gem and embedded in precious metals. Just like the Victorian amethyst relief brooch we show here, the head of a western maid carved from amethyst is embedded in a gold base made of filigree technology, and the periphery of amethyst is decorated with enamel and emeralds.

Queen Alexandra's amethyst crown

Material: platinum, diamond, amethyst.

The crown on it is a gift from Tsar Alexander III to Queen Queen Alexandra. This crown comes from Cartier, with amethyst as the main gem, and the base is made of platinum, and diamonds are inlaid on the ears of wheat as decoration. It seems that amethyst once had a very high position in history.

spodumene

Zilihui kunzite

Features: kunzite is a pink or lavender gem, and kunzite is usually lighter in color. In order to improve the color density, people will heat the brown-toned gems to 150C.

(Gemstone information comes from "Collection of Jewelry Materials Applications")

Material: 18K gold, silver, purple lithium, pearl, white diamond, tourmaline, etc.

Zilihui is also a relatively young gem, which is lavender because it contains manganese. Kunzite was first discovered by a mineralogist named George Frederick Kunz, who is also a famous American jewelry brand Tiffany &; Chief designer of co. George Frederick Kunz used purple lithium glitter in Tiffany's jewelry works, which caused a good response. Then purple lithium glitter powder is loved by jewelry designers and is often used in different high-end jewelry.

Cordierite [mineral]

(Gemstone information comes from "Collection of Jewelry Materials Applications")

Material: 18K gold, cordierite, amethyst and diamond.

Cordierite is very close to sapphire in color, so it is called water sapphire. Craftsmen will use it instead of sapphire, and even some merchants will sell high-quality cordierite as sapphire to customers. Cordierite and amethyst are used in the above 18K platinum mixed gem ring.

Material: 18K gold, pearl, shell carving and cordierite.

Because cordierite can help people identify the direction of the sun, it is called "Viking compass" by the Vikings. The brooch on it is like telling the relationship between cordierite and the sun and the moon.

topaz
