If you are lucky adequate to take a look at a natural blue ruby up close, you may notice distinct boundaries dividing highly filled blue areas from lesser saturated areas. Interestingly, there are unusual hydrogen-rich blue rubies that don't have boron that might additionally be highly zoned. Cutters have a whole lot to take into consideration when they intend just how to cut blue diamonds.
Of these 3 causes, the existence of boron is by far the most typical, so let's start there. When a diamond has actually boron pollutants but no quantifiable nitrogen in its crystal lattice, it is identified as a Type IIb. Kind IIb rubies are exceedingly uncommon, representing only regarding 0.1% of all diamonds, which clarifies why blue rubies are so limited.
There is a straight relationship between the quantity of boron present and the saturation of heaven shade and just a little concentration of the element is required to cause color expression. Kind IIb ruby crystals might have just 0.01 ppm of boron, but lots of natural rocks contain somewhere in between 0.24-0.36 ppm.
It is likewise intriguing that, unlike various other rubies, blue boron-rich rocks are outstanding conductors of power. Boron is an unusual element which leads to the question of where and exactly how blue rubies are absorbed.
Ultimately, small tears in the crystal are occasionally observed beside incorporations. This might be explained if the diamonds captured their inclusions in a setting of high stress which was subsequently eased allowing them to broaden a little and cause small fractures in the stone. All of this info has actually led scientists to suppose that the gems develop in a "superdeep" atmosphere at midsts of 410 miles or more as the outcome of plate structural activity.
These terms can be utilized by any person any kind of method that they like. There is no assurance - in fact it is almost difficult - that two various gems described as "navy" by different vendors will certainly look anything alike. Always look for the conventional GIA color category terms. While issues like fluorescence change with the different fancy shades that diamonds can exhibit, some dimensions are global.
It should be noted that pale blue fluorescence is in some cases challenging to determine in blue rubies because it can be confused with the reflection of the purple UV light being used to brighten it. If the grader has any doubts, they will certainly assign a fluorescence grade of "none."Rubies as a whole don't phosphoresce, a sensation where the diamond remains to radiance momentarily after UV light brightening it has been switched off.
The Hope Diamond, as an example, phosphoresces a red shade for approximately numerous mins after being revealed to UV lighting. Interestingly, spooky analysis of this phosphorescence shows that red is not the only shade the Hope Diamond shines. There is likewise a mild eco-friendly color which is covered up by the stronger red.
It all depends on the precise chemistry of the individual diamond. Hydrogen-rich blue rubies might fluoresce a milky yellow shade which is much more strongly expressed under long-wave UV light and lower under short-wave UV light.
That being claimed, blue rubies tend to be rather clean, if not internally remarkable. As discussed in the past, one plentiful mineral that is often discovered in blue diamonds is walstromite (CaSiO3).
Both high pressure/high temperature level (HPHT) and chemical vapor deposition (CVD) techniques may be used to expand synthetic blue rubies and these treasures can be really persuading without sophisticated laboratory tools to validate their origins. The HPHT procedure imitates the all-natural growing conditions for diamonds by subjecting carbon to extreme warmth and stress in the presence of a seed diamond.
Chemical screening shows that these gems have a tendency to have greater focus of boron in their latticework than all-natural gems with a variety of 0.82-1.12 ppm. Magnifying may expose sharp color zoning due to inconsistent mixing of chemicals. It has likewise been reported that HPHT blue diamonds do not have tatami strain patterns which are typical in all-natural Kind IIb stones.
These diamonds may phosphoresce. CVD is absolutely nothing like the natural expanding procedure of rubies and entails aerosolizing the needed chemical parts to motivate spontaneous ruby development around a small seed ruby. Blue is among the possible colors that CVD rubies might take however some state that their color may not be as saturated as HPHT diamonds.
In some cases, artificial gems go through second treatments to induce/enhance their color. For instance, it has actually been documented that some Type IIa colorless CVD diamonds have been irradiated to tackle a green blue color. There are a number of points that can be done to present or boost a blue shade in natural diamonds.
This isn't a fantastic technique because the wrappings (regardless of what they are made from) will scrape, peel, and discolor over time. More permanent approaches to gain a blue color is direct exposure to irradiation, perhaps adhered to by annealing which is a tightly managed process of heating and cooling. Kind IIb rubies might be treated with high pressure/high temperature level therapy (HPHT - not to be perplexed with the HPHT development process) to remove brownish and gray colors and improve blue.
The adhering to mines have created some excellent rocks. The Argyle was maybe one of the most renowned diamond mine worldwide many thanks to the multitude of fancy colored diamonds it created. Know for pink and red rubies, the Argyle also generated plenty of blue rubies, including some ultra-rare hydrogen-rich rocks throughout its operating years (1983-2020).
This big open-pit mine generates several diamonds, consisting of some world-famous blues. Diamonds were very first discovered below in 1957, and mining began in earnest in the 1960s. Highlighting the rarity of blue ruby discoveries, individuals were incredibly delighted when a solitary 12.47-ct blue ruby was discovered in 2013. This 31.06 ct.
It is feasible that it was given Europe by Tavernier himself. The stone has actually had several owners, including nobility like King Philip IV of Spain and Archduchess Maria Amelia of Bavaria. Just as is the instance for the Hope Ruby, there are gaps in the background of this stone.
This recutting enhanced the shade grade from Fancy Deep Grayish Blue to Fancy Deep Blue. Some weight was compromised, the enhanced shade quality is said to have actually enhanced the approximated value of the rock. Called for its first owner Sir Philip Oppenheimer, the Oppenheimer Blue is a 14.62 ct.
With a clarity grade of VVS2, the Zoe appears completely clean to the nude eye. This treasure held the document of the greatest 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 originates from the Orapa Mine in Botswana.
Presently, it is possessed by the Okavango Diamond Company who have actually lent the treasure to a gallery to be displayed openly. While the Tavernier Blue evaluated over a hundred carats, faceted blue diamonds normally do not exceed fifteen carats.
Most of the most exciting rubies on the planet are blue, from the renowned Hope Ruby to the $80-million Wittelsbach-Graff Ruby. myGemma is a BBB A+ ranked company that offers a fast, secure service for offering your blue rubies. and one of our professionals will be in touch quickly with a preliminary cost deal.
Shade refers to the real color of your diamond. Numerous blue rubies show tones of gray, green, or violet. The more pure heaven shade of your diamond, the greater its worth. Tone represents exactly how light or dark the shade of the ruby is, and saturation refers to the stamina or weak point of the shade.
Fancy color diamonds are ranked from elegant light to elegant to expensive dark to expensive intense to fancy deep to elegant vivid, depending upon the saturation and tone of the diamond's shade. Where your blue diamond drops on this range will greatly establish its worth. The cut of a diamond can affect the intensity of its color, modifying its value.
The quality of a ruby refers to just how flawless the ruby is. The fewer incorporations, or problems, that your ruby consists of, the greater its worth. Put simply, the higher the carat weight of your ruby (i.e. the larger it is), the better it is. The market conditions have a huge impact on the cost you will receive for your blue ruby.
When you have actually chosen the finest selling alternative for your demands, it is time to sell. Fill up out the on-line type to start the process and obtain payment in as little as 24 hours.
The earliest well-known blue diamonds were discovered in the Kollur mine in the Golconda region of India. Famous blue rubies from this area consist of the Idol's Eye (15th century) and the Hope Ruby (17th century). Historically, blue diamonds were recuperated mainly in India and Brazil. For the last 100 years, they have additionally been arbitrarily and intermittently found in the Premier Mine (because relabelled the Cullinan Mine) in South Africa.
Like various other tinted rubies, blue diamonds are valued based on the clarity and strength of the color initially, followed by the size and lastly the cut quality. Blue diamonds are among the rarest colored diamonds. Blue diamonds obtain their shade from the component boron yet nitrogen likewise plays a function in establishing the intensity of the shade.
Colors are classified by the shade or the actual color of the ruby consisting of secondary colors such as greenish-blue, grayish-blue and violet-blue. Tone is an additional variable that can vary from very light to very dark. Finally the saturation is the toughness of the shade. A blue ruby with high saturation or more vivid are better on the market.
Sotheby's recommends only getting blue rubies with a GIA certification. The cutting process for blue diamonds is not comparable to near-colourless rubies, or any kind of other coloured diamonds for that issue. Blue rubies typically happen as uneven, asymmetrical crystals. Heaven colour may additionally be unevenly distributed throughout the harsh crystal.
A high level of experience and experience are for that reason required to reduce and polish a blue diamond. To attain the very best feasible visual appearance, expert ruby cutters typically make alterations to conventional reducing designs. Blue Ruby Rings with Pink Diamond Accents Annually, Sotheby's has the possibility to market some of the rarest blue rubies at typically record breaking costs.
Boron in turn contributes strongly to the blue look of the ruby, which is additionally associated to exposure to high stress throughout the formation process. A cushion-shape was chosen in honor of many historical rubies, such as the Rgent and Cullinan II rubies, the cutter placed the gem in a continuous discussion with these storied treasures of the past.

Famous blue diamonds from this area include the Idolizer'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 randomly and intermittently located in the Premier Mine (since relabelled the Cullinan Mine) in South Africa.
Like various other colored diamonds, blue diamonds are valued based on the clarity and strength of the shade first, adhered to by the size and ultimately the reduced quality. Blue rubies are amongst the rarest tinted diamonds. Blue rubies obtain their shade from the aspect boron but nitrogen additionally contributes in identifying the strength of the color.
Shades are classified by the shade or the real color of the diamond consisting of second tones such as greenish-blue, grayish-blue and violet-blue. Tone is one more factor that can differ from very light to very dark. The saturation is the toughness of the color. A blue ruby with high saturation or more dazzling are extra desirable out there.
Sotheby's suggests just acquiring blue diamonds with a GIA certificate. The reducing process for blue diamonds is not analogous to near-colourless diamonds, or any other coloured diamonds for that matter.
A high degree of experience and expertise are consequently required to reduce and brighten a blue ruby. To accomplish the very best possible visual look, specialist ruby cutters commonly make modifications to traditional reducing styles. Blue Diamond Rings with Pink Diamond Accents Annually, Sotheby's has the possibility to sell several of the rarest blue rubies at frequently record damaging prices.
Boron subsequently adds strongly to the blue appearance of the ruby, which is also associated with direct exposure to high stress during the development process. Under cross-polarized light, The Mediterranean Blue presents a kind of pressure referred to as cross-hatched or "tatami" stress, frequently seen in type IIb rubies. The Mediterranean Blue diamond started as a 31.93 rough diamond sourced in South Africa and is called "an impressive instance of one of the rarest color sensations observed in a diamond." A cushion-shape was selected in honor of many historic rubies, such as the Rgent and Cullinan II rubies, the cutter placed the gem in a recurring discussion with these fabled gems of the past.
