If you are lucky enough to examine an all-natural blue diamond up close, you might observe distinct borders separating strongly filled blue locations from lesser saturated areas. Remarkably, there are rare hydrogen-rich blue rubies that do not have boron that may also be strongly zoned. Cutters have a lot to consider when they plan how to cut blue diamonds.
Of these three reasons, the existence of boron is without a doubt the most typical, so let's begin there. When a diamond has actually boron pollutants yet no quantifiable nitrogen in its crystal lattice, it is classified as a Kind IIb. Type IIb diamonds are extremely uncommon, representing only concerning 0.1% of all rubies, which discusses why blue rubies are so limited.
There is a direct connection in between the quantity of boron present and the saturation of the blue color and just a tiny concentration of the aspect is essential to trigger color expression. Type IIb diamond crystals might have just 0.01 ppm of boron, however many all-natural stones consist of somewhere between 0.24-0.36 ppm.
It is likewise intriguing that, unlike various other diamonds, blue boron-rich stones are excellent conductors of power. Boron is an unusual aspect which brings about the inquiry of where and how blue diamonds are taken in. There are a few ideas which assist researchers to answer this inquiry. It is understood that boron is concerning 100 times less concentrated in Earth's mantle than it is in the crust.
Lastly, little ruptures in the crystal are in some cases observed adjacent to additions. This might be discussed if the diamonds caught their additions in a setting of high stress which was consequently eased allowing them to expand a little and create tiny cracks in the rock. Every one of this details has led scientists to theorize that the gems form in a "superdeep" environment at depths of 410 miles or even more as the outcome of plate structural activity.
Always look for the basic GIA shade classification terms. While concerns like fluorescence modification with the numerous elegant shades that rubies can exhibit, some dimensions are universal.
It should be kept in mind that faint blue fluorescence is often difficult to identify in blue rubies since it can be confused with the reflection of the purple UV light being utilized to brighten it. If the grader has any questions, they will certainly assign a fluorescence grade of "none."Rubies as a whole don't phosphoresce, a phenomenon where the diamond proceeds to radiance momentarily after UV light brightening it has been switched off.
The Hope Ruby, for example, phosphoresces a red shade for up to several mins after being revealed to UV illumination. Remarkably, spectral evaluation of this phosphorescence reveals that red is not the only color the Hope Ruby glows. There is additionally a moderate eco-friendly shade which is concealed by the more powerful red.
It all depends upon the specific chemistry of the specific ruby. Hydrogen-rich blue rubies might fluoresce a chalky yellow shade which is much more strongly shared under long-wave UV light and lower under short-wave UV light. Stones with a strong grey part likewise may phosphoresce a yellow color. As pointed out above, some blue rubies have tiny inclusions which are a sign of an extremely deep growing environment.
That being stated, blue diamonds often tend to be rather tidy, if not inside perfect. As stated before, one abundant mineral that is usually discovered in blue diamonds is walstromite (CaSiO3).
Both high pressure/high temperature (HPHT) and chemical vapor deposition (CVD) methods may be made use of to grow artificial blue rubies and these treasures can be very persuading without sophisticated lab devices to confirm their beginnings. The HPHT procedure simulates the natural growing conditions for diamonds by subjecting carbon to extreme heat and stress in the visibility of a seed diamond.
Chemical testing shows that these gems have a tendency to have higher concentrations of boron in their lattice than natural gems with a variety of 0.82-1.12 ppm. Magnification might disclose sharp shade zoning as a result of inconsistent blending of chemicals. It has also been reported that HPHT blue diamonds do not have tatami pressure patterns which prevail in all-natural Type IIb rocks.
These diamonds may phosphoresce. CVD is nothing like the all-natural expanding process of rubies and involves aerosolizing the required chemical elements to encourage spontaneous ruby development around a tiny seed ruby. Blue is among the feasible shades that CVD rubies might take yet some state that their color might not be as saturated as HPHT rubies.
Often, artificial gems go through second therapies to induce/enhance their color. It has actually been documented that some Kind IIa anemic CVD diamonds have actually been irradiated to take on an environment-friendly blue color. There are a variety of things that can be done to present or improve a blue color in natural diamonds.
This isn't a terrific method since the coverings (regardless of what they are made from) will certainly scrape, peel, and tarnish in time. A lot more permanent techniques to get a blue shade is exposure to irradiation, potentially followed by annealing which is a securely controlled procedure of heating & cooling. Type IIb rubies may be treated with high pressure/high temperature level treatment (HPHT - not to be puzzled with the HPHT growth process) to eliminate brown and grey colors and boost blue.
The complying with mines have produced some remarkable rocks. The Argyle was perhaps one of the most famous diamond mine worldwide many thanks to the a great deal of fancy tinted rubies it generated. Know for pink and red diamonds, the Argyle additionally yielded plenty of blue diamonds, consisting of some ultra-rare hydrogen-rich stones during its operating years (1983-2020).
This big open-pit mine produces many diamonds, including some world-famous blues. Diamonds were initial discovered here in 1957, and mining started in earnest in the 1960s. Stressing the rarity of blue diamond discoveries, people were exceptionally delighted when a single 12.47-ct blue diamond was discovered in 2013. This 31.06 ct.
It is possible that it was offered Europe by Tavernier himself. The rock has had several proprietors, consisting of nobility like King Philip IV of Spain and Archduchess Maria Amelia of Bavaria. Nevertheless, equally as holds true for the Hope Ruby, there are voids in the history of this stone.
This recutting boosted the shade grade from Fancy Deep Grayish Blue to Fancy Deep Blue. This treasure held the record of the highest possible price-per-carat expense for a blue ruby up until the sale of The Blue Moon of Josephine exceeded it. This 20.46 ct. oval blue ruby comes from the Orapa Mine in Botswana.
Currently, it is possessed by the Okavango Diamond Firm who have actually offered the gem to a gallery to be displayed publicly. While the Tavernier Blue weighed over a hundred carat weights, faceted blue rubies generally do not go beyond fifteen carat weights.
Most of one of the most exciting rubies worldwide are blue, from the famous Hope Ruby to the $80-million Wittelsbach-Graff Ruby. myGemma is a BBB A+ ranked firm that supplies a quick, secure solution for offering your blue diamonds. and among our experts will certainly communicate soon with a preliminary cost offer.
Color refers to the real color of your diamond. Lots of blue rubies show tones of grey, environment-friendly, or violet. The more pure the blue shade of your diamond, the greater its worth. Tone represents how light or dark the color of the ruby is, and saturation refers to the toughness or weakness of the shade.
Fancy shade diamonds are placed from fancy light to fancy to elegant dark to expensive extreme to expensive deep to fancy vivid, depending upon the saturation and tone of the ruby's color. Where your blue diamond falls on this scale will mainly determine its worth. The cut of a diamond can impact the strength of its shade, altering its worth.
The clearness of a diamond refers to how remarkable the ruby is. The less incorporations, or flaws, that your ruby contains, the higher its well worth. Basically, the greater the carat weight of your ruby (i.e. the larger it is), the much more important it is. The market conditions have a big influence on the rate you will receive for your blue ruby.

The earliest well-known blue rubies were discovered in the Kollur mine in the Golconda area of India (Orange County 2ct Diamond Ring). Famous blue diamonds from this region consist of the Idolizer's Eye (15th century) and the Hope Diamond (17th century).
Like other colored diamonds, blue rubies are valued based upon the clearness and strength of the shade first, complied with by the dimension and finally the cut top quality. Blue rubies are among the rarest colored diamonds. Blue diamonds obtain their shade from the element boron yet nitrogen likewise plays a function in determining the strength of the shade.
Colors are categorized by the color or the actual color of the diamond consisting of secondary shades such as greenish-blue, grayish-blue and violet-blue. Tone is an additional factor that can differ from extremely light to really dark. The saturation is the strength of the color. A blue diamond with high saturation or even more dazzling are preferred in the market.
Sotheby's suggests just purchasing blue rubies with a GIA certification. The reducing procedure for blue diamonds is not analogous to near-colourless diamonds, or any various other coloured rubies for that matter. Blue rubies generally occur as uneven, unbalanced crystals. The blue colour may also be unevenly dispersed throughout the rough crystal.
A high level of experience and expertise are therefore required to cut and brighten a blue ruby. To attain the ideal possible aesthetic look, expert ruby cutters typically make alterations to traditional cutting styles. Blue Diamond Rings with Pink Diamond Accents Every year, Sotheby's has the possibility to offer several of the rarest blue diamonds at usually record damaging prices.
Boron in turn contributes strongly to heaven look of the ruby, which is likewise associated with direct exposure to high stress throughout the formation process. Under cross-polarized light, The Mediterranean Blue displays a kind of stress known as cross-hatched or "tatami" strain, generally seen in type IIb diamonds. The Mediterranean Blue ruby started as a 31.93 rough diamond sourced in South Africa and is explained as "a remarkable instance of among the rarest shade sensations observed in a ruby." A cushion-shape was picked in honor of lots of historic rubies, such as the Rgent and Cullinan II diamonds, the cutter positioned the treasure in a recurring dialogue with these fabled treasures of the past.
The earliest recognized blue rubies were located in the Kollur mine in the Golconda region of India. Famous blue rubies from this area consist of the Idolizer's Eye (15th century) and the Hope Ruby (17th century). Historically, blue diamonds were recouped primarily in India and Brazil. For the last 100 years, they have also been arbitrarily and sporadically discovered in the Premier Mine (given that relabelled the Cullinan Mine) in South Africa.
Like other colored diamonds, blue diamonds are valued based on the quality and intensity of the shade initially, complied with by the dimension and ultimately the reduced quality. Blue rubies are amongst the rarest colored rubies. Blue rubies obtain their color from the component boron yet nitrogen additionally plays a duty in establishing the strength of the shade.
Shades are identified by the hue or the real shade of the diamond consisting of secondary shades such as greenish-blue, grayish-blue and violet-blue. A blue diamond with high saturation or even more vibrant are much more desirable in the market.
Sotheby's recommends only getting blue diamonds with a GIA certificate. The cutting procedure for blue diamonds is not comparable to near-colourless diamonds, or any kind of other coloured diamonds for that matter.
A high level of experience and knowledge are as a result required to reduce and brighten a blue ruby. To attain the ideal feasible aesthetic appearance, specialist ruby cutters often make adjustments to standard reducing designs. Blue Ruby Rings with Pink Ruby Accents Yearly, Sotheby's has the chance to sell a few of the rarest blue diamonds at usually record breaking costs.
Boron in turn adds highly to heaven look of the ruby, which is likewise connected to direct exposure to high stress throughout the formation process. Under cross-polarized light, The Mediterranean Blue presents a type of stress understood as cross-hatched or "tatami" stress, commonly seen in kind IIb rubies. The Mediterranean Blue diamond began as a 31.93 rough diamond sourced in South Africa and is called "an amazing instance of among the rarest shade sensations observed in a ruby."
