If you are lucky adequate to take a look at an all-natural blue diamond up close, you might see distinct borders dividing strongly filled blue areas from lower saturated zones. Interestingly, there are unusual hydrogen-rich blue rubies that don't have boron that might also be highly zoned. Cutters have a lot to consider when they plan just how to reduce blue diamonds.
Of these three reasons, the existence of boron is without a doubt one of the most typical, so let's start there. When a diamond has actually boron impurities but no measurable nitrogen in its crystal lattice, it is categorized as a Type IIb. Kind IIb diamonds are extremely unusual, standing for only regarding 0.1% of all rubies, which explains why blue diamonds are so limited.
There is a straight connection between the amount of boron existing and the saturation of heaven shade and only a tiny concentration of the element is necessary to create shade expression. Type IIb ruby crystals may have as low as 0.01 ppm of boron, yet many natural rocks have someplace in between 0.24-0.36 ppm.
It is additionally interesting that, unlike other diamonds, blue boron-rich stones are outstanding conductors of power. Boron is an unusual element which results in the inquiry of where and exactly how blue diamonds are absorbed. There are a few ideas which assist scientists to answer this concern. First of all, it is recognized that boron is about 100 times less concentrated in Planet's mantle than it is in the crust.
Lastly, tiny tears in the crystal are occasionally observed beside incorporations. This might be clarified if the rubies captured their additions in an environment of high pressure which was consequently eased permitting them to expand a little and cause little cracks in the rock. Every one of this info has actually led scientists to theorize that the treasures form in a "superdeep" environment at depths of 410 miles or even more as the outcome of plate structural task.
These terms can be used by anybody any kind of way that they such as. There is no certainty - actually it is nearly difficult - that 2 various treasures referred to as "navy" by different sellers will certainly look anything alike. Always seek the basic GIA shade category terms. While concerns like fluorescence change with the various fancy shades that rubies can show, some measurements are universal.
It ought to be noted that faint blue fluorescence is occasionally tough to recognize in blue diamonds because it can be perplexed with the representation of the purple UV light being utilized to illuminate it. If the grader has any kind of uncertainties, they will certainly appoint a fluorescence grade of "none."Rubies as a whole don't phosphoresce, a sensation where the diamond proceeds to radiance for a brief while after UV light brightening it has actually been transformed off.
The Hope Diamond, for example, phosphoresces a red shade for as much as several minutes after being revealed to UV lights. Remarkably, spectral analysis of this phosphorescence shows that red is not the only color the Hope Diamond shines. There is additionally a mild green shade which is masked by the more powerful red.
Everything depends upon the specific chemistry of the specific diamond. Hydrogen-rich blue diamonds may fluoresce a milky yellow color which is a lot more strongly expressed under long-wave UV light and minimal under short-wave UV light. Rocks with a solid gray element likewise may phosphoresce a yellow color. As stated above, some blue rubies have microscopic incorporations which are a measure of a super deep growing environment.
That being said, blue diamonds tend to be quite clean, if not inside flawless. As stated previously, one abundant mineral that is commonly discovered in blue diamonds is walstromite (CaSiO3).
Both high pressure/high temperature (HPHT) and chemical vapor deposition (CVD) techniques may be utilized to expand artificial blue diamonds and these treasures can be very persuading without sophisticated lab equipment to validate their origins. The HPHT procedure simulates the natural expanding problems for diamonds by subjecting carbon to extreme warmth and pressure in the existence of a seed diamond.
Chemical screening shows that these gems often tend to have greater concentrations of boron in their latticework than natural treasures with a series of 0.82-1.12 ppm. Zoom might expose sharp color zoning as a result of irregular mixing of chemicals. It has likewise been reported that HPHT blue diamonds lack tatami stress patterns which prevail in all-natural Type IIb rocks.
These rubies might phosphoresce. CVD is absolutely nothing like the all-natural growing procedure of diamonds and includes aerosolizing the essential chemical parts to motivate spontaneous ruby growth around a little seed ruby. Blue is amongst the feasible colors that CVD diamonds might take yet some state that their color might not be as saturated as HPHT rubies.
Often, artificial gems are subjected to second treatments to induce/enhance their color. For instance, it has been documented that some Kind IIa anemic CVD diamonds have actually been irradiated to take on an eco-friendly blue shade. There are a number of things that can be done to introduce or improve a blue shade in all-natural rubies.
This isn't an excellent approach due to the fact that the wrappings (no issue what they are constructed from) will certainly scratch, peel off, and discolor gradually. Extra long-term approaches to gain a blue color is exposure to irradiation, possibly adhered to by annealing which is a snugly regulated procedure of heating & cooling. Type IIb rubies may be treated with high pressure/high temperature treatment (HPHT - not to be confused with the HPHT growth process) to eliminate brown and gray shades and boost blue.
The complying with mines have generated some impressive rocks. The Argyle was perhaps the most famous ruby mine in the world many thanks to the lot of elegant colored diamonds it created. Know for pink and red rubies, the Argyle likewise produced many blue rubies, including some ultra-rare hydrogen-rich stones throughout its operating years (1983-2020).
Diamonds were very first discovered right here in 1957, and mining began in earnest in the 1960s. Emphasizing the rarity of blue ruby explorations, people were incredibly excited when a solitary 12.47-ct blue diamond was unearthed in 2013. Just as is the situation for the Hope Diamond, there are spaces in the background of this rock.
This recutting enhanced the shade quality from Fancy Deep Grayish Blue to Fancy Deep Blue. This treasure held the record of the greatest price-per-carat cost for a blue diamond up until the sale of The Blue Moon of Josephine exceeded it. This 20.46 ct. oblong blue ruby comes from the Orapa Mine in Botswana.
Presently, it is owned by the Okavango Diamond Business who have actually lent the gem to a gallery to be displayed publicly. While the Tavernier Blue evaluated over a hundred carats, faceted blue rubies typically do not go beyond fifteen carat weights.
A lot of the most exciting diamonds in the globe are blue, from the famous Hope Diamond to the $80-million Wittelsbach-Graff Ruby. myGemma is a BBB A+ ranked firm that uses a quick, secure solution for offering your blue rubies. and one of our specialists will certainly communicate soon with a first cost deal.
Color refers to the real color of your ruby. Numerous blue rubies show tones of gray, green, or violet. The even more pure heaven shade of your ruby, the greater its value. Tone signifies how light or dark the shade of the diamond is, and saturation describes the toughness or weakness of the shade.

The earliest recognized blue diamonds were located in the Kollur mine in the Golconda region of India. Famous blue diamonds from this region include the Idol's Eye (15th century) and the Hope Diamond (17th century). Historically, blue diamonds were recuperated mostly in India and Brazil. For the last 100 years, they have likewise been arbitrarily and occasionally located in the Premier Mine (considering that relabelled the Cullinan Mine) in South Africa.
Like other tinted rubies, blue diamonds are valued based upon the quality and strength of the color first, followed by the size and lastly the reduced quality. Blue diamonds are amongst the rarest colored rubies. Blue diamonds obtain their color from the element boron but nitrogen likewise plays a duty in figuring out the strength of the color.
Colors are categorized by the tone or the actual color of the ruby consisting of additional tones such as greenish-blue, grayish-blue and violet-blue. A blue diamond with high saturation or more dazzling are more preferable in the market.
Sotheby's advises only buying blue rubies with a GIA certification. The cutting procedure for blue diamonds is not similar to near-colourless diamonds, or any various other coloured rubies for that matter. Blue diamonds typically take place as irregular, unbalanced crystals. Heaven colour may also be unevenly distributed throughout the rough crystal.
A high level of experience and competence are as a result needed to cut and brighten a blue diamond. To achieve the ideal feasible aesthetic appearance, expert diamond cutters typically make adjustments to standard cutting styles. Blue Ruby Rings with Pink Diamond Accents Every year, Sotheby's has the opportunity to sell several of the rarest blue diamonds at commonly record breaking rates.
Boron in turn contributes strongly to heaven appearance of the diamond, which is additionally associated with exposure to high pressure during the formation procedure. Under cross-polarized light, The Mediterranean Blue displays a sort of stress referred to as cross-hatched or "tatami" strain, commonly seen in type IIb diamonds. The Mediterranean Blue diamond started as a 31.93 harsh ruby sourced in South Africa and is referred to as "an impressive instance of among the rarest shade experiences observed in a ruby." A cushion-shape was picked in honor of several historical rubies, such as the Rgent and Cullinan II diamonds, the cutter put the treasure in a recurring dialogue with these storied treasures of the past.

Famous blue diamonds from this region include the Idol's Eye (15th century) and the Hope Diamond (17th century). Historically, blue diamonds were recuperated mainly in India and Brazil. For the last 100 years, they have actually also been randomly and sporadically located in the Premier Mine (because renamed the Cullinan Mine) in South Africa.
Like other tinted diamonds, blue rubies are valued based upon the quality and intensity of the color first, adhered to by the size and ultimately the cut quality. Blue diamonds are amongst the rarest tinted rubies. Blue diamonds get their color from the component boron but nitrogen likewise contributes in determining the intensity of the color.
Shades are categorized by the shade or the real color of the diamond consisting of additional colors such as greenish-blue, grayish-blue and violet-blue. Tone is another element that can vary from extremely light to very dark. Ultimately the saturation is the stamina of the color. A blue diamond with high saturation or more dazzling are much more preferable on the market.
Sotheby's advises just buying blue diamonds with a GIA certificate. The reducing procedure for blue rubies is not similar to near-colourless diamonds, or any type of various other coloured diamonds for that matter. Blue diamonds normally occur as irregular, asymmetrical crystals. Heaven colour may also be unevenly dispersed throughout the rough crystal.
A high degree of experience and knowledge are for that reason needed to reduce and polish a blue ruby. To attain the best feasible aesthetic appearance, expert ruby cutters frequently make alterations to typical cutting designs. Blue Ruby Rings with Pink Ruby Accents Annually, Sotheby's has the chance to sell several of the rarest blue diamonds at typically record breaking rates.
Boron in turn contributes highly to the blue appearance of the diamond, which is additionally connected to exposure to high stress throughout the formation process.
