If you are fortunate adequate to examine a natural blue ruby up close, you might observe distinct borders separating strongly saturated blue locations from minimal saturated areas. Surprisingly, there are uncommon hydrogen-rich blue diamonds that do not have boron that may likewise be strongly zoned. Cutters have a great deal to take into consideration when they plan how to reduce blue diamonds.
Of these three reasons, the existence of boron is by much the most common, so allow's begin there. When a diamond has actually boron pollutants yet no quantifiable nitrogen in its crystal latticework, it is categorized as a Kind IIb. Type IIb rubies are extremely uncommon, standing for only regarding 0.1% of all diamonds, which explains why blue rubies are so limited.
There is a direct connection in between the amount of boron present and the saturation of the blue shade and just a tiny focus of the component is needed to create shade expression. Type IIb ruby crystals may have just 0.01 ppm of boron, yet several natural stones have somewhere in between 0.24-0.36 ppm.
It is likewise fascinating that, unlike other rubies, blue boron-rich stones are excellent conductors of electricity. Boron is a rare component which causes the concern of where and exactly how blue rubies are taken in. There are a few clues which help researchers to address this concern. To start with, it is recognized that boron is about 100 times less focused in Planet's mantle than it is in the crust.
Small tears in the crystal are occasionally observed nearby to inclusions. This might be explained if the rubies captured their inclusions in a setting of high pressure which was subsequently alleviated enabling them to increase a little and trigger tiny cracks in the rock. Every one of this info has led scientists to think that the treasures form in a "superdeep" atmosphere at depths of 410 miles or more as the outcome of plate structural activity.
These terms can be utilized by any person any means that they such as. There is no certainty - actually it is virtually impossible - that 2 various gems explained as "navy" by different vendors will look anything alike. Constantly seek the standard GIA shade classification terms. While problems like fluorescence change with the various fancy shades that diamonds can exhibit, some measurements are global.
It must be noted that pale blue fluorescence is occasionally difficult to identify in blue diamonds because it can be confused with the reflection of the purple UV light being made use of to brighten it. If the grader has any questions, they will designate a fluorescence grade of "none."Rubies in basic don't phosphoresce, a phenomenon where the ruby remains to radiance momentarily after UV light illuminating it has actually been shut off.
The Hope Diamond, for circumstances, phosphoresces a red color for as much as a number of mins after being exposed to UV illumination. Interestingly, spooky evaluation of this phosphorescence shows that red is not the only color the Hope Diamond shines. There is likewise a moderate green color which is covered up by the stronger red.
It all depends on the exact chemistry of the specific ruby. Hydrogen-rich blue rubies may fluoresce a chalky yellow color which is a lot more highly shared under long-wave UV light and lesser under short-wave UV light.
That being stated, blue rubies often tend to be rather tidy, if not inside remarkable. You may see some opaque black inclusions or clear, creamy colored, or reflective graining. As discussed previously, one bountiful mineral that is typically discovered in blue diamonds is walstromite (CaSiO3). Other permutations of CaSiO3 may likewise be existing.
Both high pressure/high temperature level (HPHT) and chemical vapor deposition (CVD) techniques might be utilized to grow artificial blue diamonds and these gems can be extremely persuading without sophisticated research laboratory tools to validate their origins. The HPHT procedure resembles the natural growing problems for rubies by subjecting carbon to extreme heat and pressure in the visibility of a seed ruby.
Chemical testing reveals that these gems tend to have higher concentrations of boron in their lattice than all-natural gems with a series of 0.82-1.12 ppm. Zoom might disclose sharp color zoning as a result of inconsistent mixing of chemicals. It has additionally been reported that HPHT blue diamonds do not have tatami stress patterns which are common in natural Kind IIb stones.
These rubies may phosphoresce. CVD is nothing like the natural expanding procedure of rubies and includes aerosolizing the necessary chemical elements to motivate spontaneous diamond development around a tiny seed ruby. Blue is amongst the feasible shades that CVD diamonds might take however some state that their color may not be as saturated as HPHT diamonds.
Occasionally, artificial gems are subjected to additional therapies to induce/enhance their color. For example, it has been recorded that some Kind IIa anemic CVD rubies have been irradiated to tackle an environment-friendly blue color. There are a variety of things that can be done to introduce or boost a blue shade in natural diamonds.
This isn't a great approach due to the fact that the coverings (regardless of what they are made of) will scrape, peel off, and blemish over time. A lot more irreversible approaches to acquire a blue color is direct exposure to irradiation, possibly adhered to by annealing which is a securely managed procedure of home heating and cooling. Type IIb rubies may be treated with high pressure/high temperature treatment (HPHT - not to be confused with the HPHT growth process) to get rid of brown and grey colors and improve blue.
The complying with mines have actually produced some outstanding stones. The Argyle was perhaps the most popular diamond mine on the planet many thanks to the big number of fancy colored rubies it generated. Know for pink and red rubies, the Argyle likewise generated several blue rubies, including some ultra-rare hydrogen-rich rocks throughout its operating years (1983-2020).
This large open-pit mine generates many rubies, including some world-famous blues. Rubies were very first uncovered below in 1957, and mining started in earnest in the 1960s. Highlighting the rarity of blue ruby explorations, people were very excited when a single 12.47-ct blue ruby was discovered in 2013. This 31.06 ct.
It is possible that it was brought to Europe by Tavernier himself. The stone has had many proprietors, including aristocracy like King Philip IV of Spain and Archduchess Maria Amelia of Bavaria. Simply as is the case for the Hope Diamond, there are voids in the history of this rock.
This recutting enhanced the shade grade from Fancy Deep Grayish Blue to Fancy Deep Blue. Although some weight was compromised, the improved shade quality is said to have actually boosted the approximated value of the stone. Named for its first owner Sir Philip Oppenheimer, the Oppenheimer Blue is a 14.62 ct.
With a clarity quality of VVS2, the Zoe appears flawlessly tidy to the nude eye. This gem held the record of the greatest price-per-carat expense 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.
This diamond has yet to be cost public auction. Presently, it is owned by the Okavango Ruby Business that have lent the gem to a gallery to be shown openly. While the Tavernier Blue evaluated over a hundred carats, faceted blue rubies normally do not go beyond fifteen carat weights. Indeed, a lot of the significant treasures cost auction consider under 10 carats.
A lot of the most captivating rubies on the planet are blue, from the popular Hope Ruby to the $80-million Wittelsbach-Graff Ruby. myGemma is a BBB A+ rated company that offers a fast, secure service for offering your blue rubies. and one of our experts will be in touch quickly with an initial price offer.
Tone refers to the real color of your diamond. Several blue diamonds exhibit tones of grey, environment-friendly, or violet.
Fancy shade rubies are placed from elegant light to fancy to expensive dark to expensive intense to expensive deep to fancy vibrant, depending upon the saturation and tone of the ruby's color. Where your blue diamond falls on this scale will mostly establish its worth. The cut of a diamond can influence the strength of its color, modifying its value.
The quality of a diamond describes how remarkable the diamond is. The less additions, or imperfections, that your diamond contains, the greater its worth. Just placed, the higher the carat weight of your diamond (i.e. the larger it is), the better it is. The marketplace conditions have a huge effect on the cost you will receive for your blue ruby.

The earliest recognized blue diamonds were located in the Kollur mine in the Golconda area of India. Famous blue diamonds from this area consist of the Idol's Eye (15th century) and the Hope Diamond (17th century). Historically, blue diamonds were recovered mostly in India and Brazil. For the last 100 years, they have actually also been arbitrarily and intermittently found in the Premier Mine (since relabelled the Cullinan Mine) in South Africa.
Like various other colored rubies, blue diamonds are valued based on the clearness and strength of the color initially, adhered to by the dimension and lastly the reduced top quality. Blue rubies are among the rarest tinted diamonds. Blue diamonds obtain their color from the aspect boron however nitrogen likewise contributes in figuring out the strength of the color.
Colors are classified by the tone or the actual color of the ruby consisting of second hues such as greenish-blue, grayish-blue and violet-blue. Tone is another element that can differ from extremely light to very dark. Ultimately the saturation is the toughness of the shade. A blue ruby with high saturation or even more brilliant are preferred out there.
Sotheby's suggests just acquiring blue rubies with a GIA certification. The cutting procedure for blue rubies is not comparable to near-colourless diamonds, or any kind of other coloured rubies for that matter. Blue rubies normally take place as uneven, unbalanced crystals. The blue colour might also be unevenly distributed throughout the harsh crystal.
