If you are fortunate sufficient to examine a natural blue diamond up close, you may see distinctive boundaries dividing highly filled blue locations from lower saturated zones. Surprisingly, there are rare hydrogen-rich blue rubies that don't have boron that may additionally be strongly zoned. Cutters have a great deal to consider when they plan how to cut blue rubies.
Of these 3 reasons, the visibility of boron is by far one of the most typical, so allow's start there. When a diamond has actually boron impurities yet no quantifiable nitrogen in its crystal latticework, it is identified as a Kind IIb. Type IIb rubies are exceedingly uncommon, standing for only regarding 0.1% of all rubies, which discusses why blue diamonds are so limited.
There is a direct relationship in between the amount of boron existing and the saturation of the blue shade and just a little focus of the element is necessary to trigger color expression. Kind IIb ruby crystals might have as low as 0.01 ppm of boron, yet several natural stones have someplace between 0.24-0.36 ppm.
It is additionally fascinating that, unlike other rubies, blue boron-rich rocks are outstanding conductors of electrical energy. Boron is a rare aspect which causes the inquiry of where and just how blue diamonds are soaked up. There are a couple of hints which aid researchers to address this concern. It is understood that boron is regarding 100 times less focused in Earth's mantle than it is in the crust.
Lastly, small ruptures in the crystal are often observed adjacent to inclusions. This might be discussed if the rubies captured their incorporations in a setting of high pressure which was ultimately alleviated permitting them to expand a little and create tiny splits in the stone. All of this information has actually led researchers to suppose that the treasures create in a "superdeep" environment at midsts of 410 miles or even more as the outcome of plate structural activity.
Constantly look for the basic GIA color classification terms. While problems like fluorescence modification with the numerous fancy shades that diamonds can display, some measurements are global.
It should be noted that pale blue fluorescence is sometimes challenging to determine in blue diamonds due to the fact that it can be confused with the representation of the purple UV light being used to illuminate it. If the grader has any doubts, they will certainly assign a fluorescence quality of "none."Rubies as a whole do not phosphoresce, a sensation where the diamond continues to glow momentarily after UV light illuminating it has been turned off.
The Hope Diamond, as an example, phosphoresces a red color for approximately numerous mins after being exposed to UV illumination. Interestingly, spooky analysis of this phosphorescence shows that red is not the only shade the Hope Diamond shines. There is additionally a mild green color which is covered up by the stronger red.
It all depends on the precise chemistry of the individual ruby. Hydrogen-rich blue rubies may fluoresce a milky yellow color which is more strongly revealed under long-wave UV light and lower under short-wave UV light.
That being claimed, blue rubies often tend to be fairly tidy, otherwise internally remarkable. You may see some nontransparent black inclusions or clear, whitish, or reflective graining. As pointed out before, one abundant mineral that is often found in blue rubies is walstromite (CaSiO3). Other permutations of CaSiO3 might also be existing.
Both high pressure/high temperature level (HPHT) and chemical vapor deposition (CVD) approaches may be made use of to expand artificial blue rubies and these gems can be very convincing without innovative lab equipment to validate their origins. The HPHT process imitates the natural growing problems for rubies by subjecting carbon to intense warm and pressure in the presence of a seed ruby.
Chemical screening reveals that these treasures tend to have higher focus of boron in their latticework than all-natural treasures with a series of 0.82-1.12 ppm. Magnification may reveal sharp color zoning due to irregular mixing of chemicals. It has additionally been reported that HPHT blue diamonds do not have tatami strain patterns which prevail in natural Type IIb rocks.
These rubies may phosphoresce. CVD is absolutely nothing like the natural expanding process of diamonds and includes aerosolizing the essential chemical components to encourage spontaneous ruby development around a tiny seed diamond. Blue is amongst the feasible colors that CVD rubies might take but some state that their color might not be as saturated as HPHT diamonds.
Occasionally, artificial gems undergo second therapies to induce/enhance their shade. For example, it has been documented that some Type IIa anemic CVD rubies have been irradiated to tackle an eco-friendly blue shade. There are a variety of things that can be done to introduce or boost a blue shade in natural diamonds.
This isn't a terrific technique because the wrappings (whatever they are made from) will certainly scratch, peel off, and stain with time. Extra long-term methods to get a blue hue is direct exposure to irradiation, perhaps adhered to by annealing which is a securely controlled process of heating and air conditioning. Kind IIb rubies might be treated with high pressure/high temperature treatment (HPHT - not to be perplexed with the HPHT development process) to eliminate brownish and grey colors and boost blue.
The complying with mines have actually generated some remarkable stones. The Argyle was probably the most renowned diamond mine on the planet many thanks to the multitude of fancy tinted rubies it produced. Know for pink and red diamonds, the Argyle additionally produced plenty of blue rubies, consisting of some ultra-rare hydrogen-rich stones during its operating years (1983-2020).
This huge open-pit mine generates several diamonds, consisting of some world-famous blues. Rubies were initial found below in 1957, and mining started in earnest in the 1960s. Emphasizing the rarity of blue ruby explorations, people were extremely thrilled 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 lots of proprietors, consisting of nobility like King Philip IV of Spain and Archduchess Maria Amelia of Bavaria. Just as is the instance for the Hope Ruby, there are spaces in the history of this stone.
This recutting improved the color quality from Fancy Deep Grayish Blue to Fancy Deep Blue. Some weight was compromised, the enhanced shade quality is said to have boosted the estimated value of the rock. Named for its very first owner Sir Philip Oppenheimer, the Oppenheimer Blue is a 14.62 ct.
With a clarity grade of VVS2, the Zoe shows up completely clean to the naked eye. This gem held the record of the highest possible price-per-carat expense for a blue ruby till the sale of The Blue Moon of Josephine exceeded it. This 20.46 ct. oval blue diamond comes from the Orapa Mine in Botswana.
Currently, it is possessed by the Okavango Ruby Business that have provided the gem to a gallery to be shown openly. While the Tavernier Blue weighed over a hundred carat weights, faceted blue diamonds typically don't exceed fifteen carats.

Boron in turn adds strongly to the blue look of the diamond, which is additionally connected to exposure to high pressure during the development process. Under cross-polarized light, The Mediterranean Blue displays a kind of stress referred to as cross-hatched or "tatami" pressure, generally 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 example of one of the rarest shade feelings observed in a ruby." A cushion-shape was picked in honor of many historic rubies, such as the Rgent and Cullinan II rubies, the cutter put the gem in a continuous dialogue with these fabled gems of the past.
