Category: Colored Diamond

The striking blue hue of natural blue diamonds stems from elemental impurities absorbed during the diamonds’ deep underground formation millions of years ago. When boron atoms infiltrate the diamond’s carbon crystal lattice, they create acceptor energy bands within the mineral’s internal atomic structure. These unique energy bands absorb long-wavelength segments of visible natural light; the remaining unabsorbed short-wave light reflected to the human eye produces the characteristic cool blue shade that defines these rare stones. Due to the precise geological conditions required for boron to integrate evenly into diamond crystals, naturally occurring blue diamonds are exceptionally hard to find. Even diminutive natural blue diamonds of small carat weights can command valuations reaching tens of thousands of currency units.

Beyond colour performance, multiple core factors jointly dictate a blue diamond’s final market price, including carat weight, colour saturation, tone purity, clarity grade and cut brilliance, with colour characteristics consistently acting as the most decisive pricing factor.If you are captivated by the serene cerulean shade of clear skies and the profound dark blue of the deep ocean, collecting a genuine natural blue diamond is an unparalleled choice for gem enthusiasts. A massive price gap separates lab-created synthetic blue diamonds from naturally formed counterparts, with synthetic variants costing merely a fraction of the price of rare natural stones. Therefore, buyers must exercise extreme caution to avoid accidentally purchasing artificially treated or laboratory-grown blue diamonds when shopping. It is critical to verify an official GIA diamond grading certificate as authoritative proof of authenticity. Certificates for unaltered natural blue diamonds will clearly print the marking “natural” to distinguish them from treated or synthetic alternatives. For authentic blue diamonds sourced from the Argyle Mine, an exclusive laser engraving bearing the “Argyle” identification code is etched onto the stone’s girdle, serving as an exclusive origin authentication mark for collectors.

For buyers working within constrained budgets, or those who do not favour unmodified pure blue tones, there are numerous beautiful alternative fancy blue diamond varieties available on the market. Blue-purple, blue-grey and blue-green diamonds carry soft, unique mixed secondary hues, deliver mesmerising visual appeal, and feature far more accessible price points compared to fully saturated pure blue diamonds. These toned hybrid blue diamonds retain the elegant cool undertones that make blue gemstones desirable, while offering flexible options for collectors with diverse aesthetic preferences and spending limits.

In ten thousand diamonds only just one is colored diamond, including the orange diamond, blue diamond, red diamond, pink diamond, green diamond, yellow diamond and other fancy color diamonds, so when purchase colored diamonds is mostly focus on the intensity color, when buying colorless diamond refer to the 4Cs standard, such as cutting degree and clarity degree, compare with colored diamonds, when buying colored diamonds are not the most important factors, so the color, intensity and color richness is considered as the most important factor in buying color diamonds. The more vivid color, color diamonds are rarer and more valuable, for yellow diamond, there is fancy light, fancy, fancy intense and fancy vivid color degree.

Colored Diamond Weight

Except for color, the carat weight has the biggest influence on the value of fancy color diamond, found big colored diamond frequency is much smaller than small colored diamonds when mining, this makes big color diamond more valuable. Therefore, color diamond prices rising with the carat weight.

Colored Diamond Clarity

Due to the color diamond require have a natural color, the importance of its clarity is not as important as other colorless diamond. This is because the inclusions are covered by the color of the diamond.

Argyle diamond mine is one of the world’s most productive diamond mines, which is located in the kimberlite zone eastern part of western Australia, Argyle mine is the world’s main source of red diamond and pink diamond, and occupied ninety percent of the world pink diamond and red diamond annual output. Argyle mine also produces champagne, cognac color, purple and blue diamond.

Argyle diamond mine famous for the good quality fancy diamonds all over the world, the mine rock containing diamond was discovered in 1979, and the company began to impact mining in 1983. Argyle mine began operating in 1985, the colored diamond supply structure of the world began to change since that time, especially in the pink diamond market. Argyle mine produce 35 million carats diamond annually, which occupied one third of the world diamond, the five percent of the diamond is regarded as the gem grade.

The pink diamond from Argyle will be laser exclusive yards around the diamond waist, like this picture below, the diamond laser with argyle logo and unique numbers, and indicate the logo and numbers inside the GIA certificate, this is an important way to identify the argyle loose diamond.

Rio Tinto Group will be held the Argyle Pink Diamonds Tender every year, the pink diamonds are exhibited in the large diamond exhibition centre all over the world.

In 2001, Argyle diamond mine’s life close to end, Rio Tinto board of directors approved the building plan of underground mining field in 2005, which is expected to extend the age of the mine to 2018.

Fancy color diamond become more and more popular these years, many people think diamond is colorless and transparent, lots of people don’t know there is color diamonds in the world, in fact, the world of diamonds is not only one kind of color, who is also colorful. Most people think that the color of the diamond the whiter the more better, but economic value and collection value of color diamond are also very precious, because which is more rare than the normal diamond, so the fancy color diamond has more extraordinary charm. Although light color and color saturation is faint, the diamonds all can be named fancy color diamonds. Among these color diamonds, red and green is extremely rare, the next is red purple, orange, pink, purple and blue color. We often given priority yellow and brown color diamonds in jewelry market, the bright and beautiful yellow diamond has more economic value.

Green diamond, which is generated after crystallization generated when affected by underground radiation material, and result in green color finally, fancy green color loose diamond series including green with yellow, gray, green, olive green and chameleon colored diamonds.

Red diamond, which may be caused by deformation of crystal structure and mixed nitrogen, there is just one degree in red diamond color, which is fancy red (and no vivid, fancy intense and lightred degree). The red diamond series including red with brown, pink with red, red with purple, and so on. Red diamond is the most rare among fancy color diamond, and only a handful of gemstone can be rated as red diamond, only the pure blood red without other additional in it, the blood red color is gorgeous, so which is the extremely precious and rare color diamonds.

Yellow diamond, canary yellow and fancy vivid yellow bright color or bright color yellow is because of containing a single original nitrogen, squeezed into the carbon atoms in cubic crystal system closely packed in the diamond lattice, the yellow color is due to the lattice of carbon atoms and nitrogen replacement, so appear yellow color, this type of color mostly from colorless to pale yellow, GIA specified color grading after Z just can named yellow diamond, this color series varieties much more than other colors, but the top brilliant color yellow diamond is too little.

Pink diamond, Due to the phenomenon of twin crystal, crystal distortion and dislocation in crystal structure, the pink diamond series including brown with pink, orange with pink, red, pink with purple or bright red color.

Purple diamond, it is between red and blue color, because the purple diamond absorption green to yellow light waves in the visible light region, so there is common phenomenon of twin crystal structure, the pure purple colored diamonds almost is almost no adjective, but can be found the pink with purple and violet with pink color loose diamond.

Black diamond, a lot of dark opaque inclusions led to the black color, but the black diamond still have adamantine luster, the darker the more precious.

Orange diamond, due to crystal structure defects and nitrogen atoms, the orange diamond vice color is yellow, brown, pink and red, the pure orange diamond is very rare in nature, the diamond series including deep brown orange, orange pink and orange red.

The blue diamond, Mostly due to this kinds of diamond containing boron element, blue color diamond series including grey with blue, green with blue, blue with grey color.

Chameleon diamonds. gray, yellow and green olives combinations, the chameleon diamond is discoloration colorful appeal like the chameleon, stored in a dark place, after a slowly frozen, chameleon diamond will change to olives color, and then in only a few seconds or minutes, restore original color and lustre.

Grey diamond, due to internal lattice deformation dislocation or carbon atoms, grey color diamond series consists of dark grey, the lottery gray and gray green.

The world’s largest flawless blue diamond’s which is 13.22 carat, the pear-shaped blue diamond was estimate of $21 million to $25 million.

Green diamond

Green diamond is very rare, each layer by natural radiation caused by change of lattice structure in the diamond. There was a story said that a diamond cutter, came to a mine bought a green stone, after come back want to cut it into a lot of green diamond to sell, he didn’t think the cut into the white, originally this diamond just received radiation surface, they didn’t turn green, and lost a lot of money.

Blue color diamond

Diamond contains trace elements of boron in the process of formation, and with well electrical conductivity, so present with the sky blue, blue to deep blue color, among them with deep blue is the best. Blue diamond may happen with a gray or black color, if the blue diamond appears green or blue with green color, because contains nitrogen impurities in crystal. Deep blue diamond is a rarity and is extremely rare of them, South Africa’s remier mine is the main origin of blue diamond.

Yellow color diamond

When some carbon atoms are replaced by nitrogen atoms in diamond, the diamond began to absorb blue and purple light, and will present a yellow color. Yellow diamond also referred to as the gold diamond, which is one of the most common color in colored diamonds, usually present a yellow, golden yellow, faint yellow and amber color, golden yellow especially the most precious within them, and which is also known as the canary yellow, fancy vivid is the top grade in yellow color diamonds.

Are you fond of jewelry? If yes, you are probably familiar with the different types of jewelry pieces and designs. If you are not aware of this, you should know that the custom jewelry designs are extremely popular among consumers who are looking for alternative pieces today. Continue reading to find out about some of the advantages of choosing custom-made jewel pieces.

First and foremost, it is important to mention that custom jewelry pieces are not always the best choices for everyone. But, they are definitely the designs to choose if you want the option to design jewelry to match your budget, fashion and style.

Some of the Advantages of Custom Jewelry

All jewelry designs will not suit every woman. The choice of jewelry designs usually varies significantly from one individual to the next. These days, the local jewelry stores and the online retailers carry many traditional designs as well as the latest fashion pieces. Therefore, the best option is always to opt for the custom jewelry as this will allow you to add your own designs. This way, you will get the desired fashions and styles.

With custom jewelry, you can also choose your own gemstones and precious metals. For instance, you have the option to decide whether to get a ruby or diamond stone for a custom ring. If you want a gold bracelet with sapphires or diamonds, a design with large stones within the 1 – 3 carat might be a stretch for your budget. So, you might want to get a similar bracelet design with sterling silver if you can’t afford one of the sturdy gold types. Bear in mind that the light bracelet can snap and bend, plus inadequate metal weight means that loose gemstones could get lost.

The price is another great advantage of buying custom jewelry. There is no doubt that you might find items that you like in the stores, but the prices are way out of your spending budget. On the other hand, you might find jewel pieces to match your budget, but you are not too fond of the style. Choosing the custom-made jewel pieces will give you more control over the amount that you would spend as well as the weight and designs of your jewelry. It’s definitely not like choosing jewelry that you will find on display in the shops.

At the end of the day, you should understand exactly what to expect from the custom made jewelry pieces to enjoy all the benefits. Perhaps the most interesting thing about custom-made or handcrafted jewels is that you are getting to wear unique pieces. You will definitely feel proud to tell others that you are wearing custom jewelry with your own designs.

If we are plan to design the colored diamond jewelry by ourselves, choose the Leibish company, which can realize your dream.
