Burmese Pigeon Blood RubyBurma Pigeon Blood Ruby
Vibrant Crimson is the No. 3 on a 4 chart, as it has been on our website since 2001. GRS's DELFINITION OF "PIGEON'S BLOOD" The traditional gems markets were ruins of Burmese pigeon blood, 95% of which until recently came from the Mong Hsu source (mainly heat-treated), about 5% from Mogok and 1% from Namya, blended, heat-treated and untreated.
Mong Hsu non-heated Ruby are very characteristic of Mong Hsu to part with Mogok and only a small part of Mong Hsu's non-heated Ruby are of the blood colour of the dove due to the violet colouring. During the last years pigeon blood colours from Vietnam, Tajikistan, Afghanistan and Madagascar and only recently from Mozambique have been found.
About 20% of the high-quality bright shining colours from Mozambique (internal statistics on the basis of rocks that have been examined in GRS laboratories) are given the colour "pigeon blood" of the GRS model (indicated on the title page of the Gem Report). While Mozambique ruby may have slightly lower levels of fluorescent activity than Burmese ruby, some rocks may exhibit moderate to high levels of fluorescent activity when subjected to UV radiation (365 nm).
There are some lively pigeon blood colours from Mozambique and Burma that cannot be differentiated by the day. While most Mozambique ruins are hot, a significant part of the ruins of this source is heatless and of outstanding clear. Over the last 2 years, these have replaced Mogok jewels on the global markets, especially in large size between 5 and over 10 ct.
Mozambique's large-format ruby is incomparable in terms of both colour and light. There are two sets of Burmese and Mozambique jewels. Each GRS location has one rate (Switzerland, Hong Kong, Bangkok and Sri Lanka). GRS released the pigeon blood design for ruby, bluish cornflowers and king blues for sapphire in 1996.
Since 2001, the GRS has owned the top-level domain named pigeonblood.com. Used extensively in GRS coverage, the ink types have evolved from romanticising books to a global benchmark that is now used by almost all of our labs. Do other laboratories use the term "pigeon blood"?
It has been used by many other laboratories that are often quoted in today's auctions: the "auction catalogue": Can also be described in commerce as "pigeon blood" or poetically as "pigeon blood". Whilst this formulation will appear on the front page of the competition report, in the brief annotations of the catalogue it is often just substituted as "pigeon blood" colour by other laboratories or the colour level is directly indicated in the annex of other gemstoneports ("no waiver").
Our colour sorting has therefore become established on an international scale and is also used by other labs, although unfortunately it is used without a quotation from GRS and sometimes even requires the launch of the concepts on the notions. Colour gradations are allocated irrespective of the source of the stones. Contrary to the source, the named colour gradations can be assessed by the end user with ease (much simpler than the original opinion).
It is therefore advantageous for the end user to separate ink types from their source. Linking 2 factors (origin and colour sorting) can make it more difficult for the end user to assess the quality of the products (usually he cannot assess the source because of a shortage of advanced tools and colour references).
In the last 2 years, the retail sector has been accepting the colour "pigeon blood" for other sources than Burma, for example Mozambique. Consumers can readily match Burmese and Mozambique jewels to the blood colour of the dove and judge for themselves the precision by comparison and agreement or disagreement.
The overwhelming bulk of Burmese pigeon-blooded ruby is associated with Mong Hsu rocks (near the Thai border), a 250 km from Mogok. Burma's ruby output peaked between 2002 and 2008 and has now been superseded by Mozambique as the world's top ruby-manufacturer.
This pigeon blood brand is an outstanding successors to Mozambique jewels of the same family. Pigeon blood and the king blues are concepts that have succeeded in removing our original awareness and focusing our awareness on colour and appearance. It allows various gemstone manufacturers to compete fairly in the coloured gemstone markets, minimising the benefits of brand manufacturers such as Burma (Myanmar) and Kashmir (India) to domination of the ruby and saphire markets.
This is to let the retail sector know that our colour schemes are in the best interest of the end user and the entire gemstones sector. Savour our historic review of the development of today's globally recognized colour standard. Although the words "pigeon blood" and "royal blue" have historic literary origins that describe the ruby and sapphire, it has also been used by GRS labs for over a decennium to describe the colour of the world's most delicate ruby and sapphire.
In the following section you will find a brief overview of the bibliography in which our lab results with these colour concepts have been used. Most of our research was done in the field of art auctions. The information can be used to determine the value of jewels and saphires, as the results of the bids are posted on line or can be found in the GRS-Bibliothek.
Some of the articles that have been released, especially the articles that have been put in our auctions with our "pigeon blood" and "royal blue" colour gradations, are contained in this paper (Tab. 02, 03, 04, 05). First two GRS accounts ever released appear in a Christie's London catalog for the June 1996 sale for a Saphir and Diamant ring (lot 208, Peretti Gemlab AP-9602007, the former name of GRS) and for a ruby from Christie's in London 1997 (lot 91, GRL9704027, GRL was later re-named GRS).
Back then, we used our colour vocabulary only for select gemstones. Sotheby' s in Geneva, Switzerland, in May 2000, the first high-quality 22.54 ct Burmese ruby (lot 459) was beaten for CHF 1,600,000 without a bonus (equivalent to US$ 900,000 at the time) with a GRS certificate (1997 certificate, GRL9711067) and a second certificate from another lab.
This was the first article to be auctioned in Hong Kong and was included in a Christie's catalog (lot 1620) in May 2000 with a GRS review (GRS2000-01277) for an "Antique Style Ruby and Diamond Butterfly Patch Bro". First ruby to exceed $3 million was traded with a GRS reported (along with other lab reports) at Sotheby's in Geneva (November 2000) for an unreheated Burmese ruby (lot 480, Superb Ruby and Diamond Ring, 32.67ct).
GRS pigeon blood" GRS grade The first GRS-certified pigeon blood ruby in the million US dollars class was sold by Sotheby's in May 2002 (lot 240, 8. 01 carat ruby, GRS No. 2002-03295). Our results have been released by the Auctioneers:: "Ruby is of Burmese origins, no evidence of thermic appreciation and that the color is bright ruby color (GRS-type "pigeon blood"), with the added commentary on rarity:
Sotheby' s in Hong Kong (May 2002), where an important set of Burmese ruby pendants rings was auctioned (GRS Review No. 2001-11585 of November 2001), the oldest GRS account "Pigeon Blood" released by an Auctioneer. In recent years, GRS-certified jewels with the blood colour descriptions of pigeons in important collars have been found more frequently in high-quality collars at Christie's between 2007-2012 in Hong Kong (every year between 2007-2012, see tab.
02, 03) and in Hong Kong by Sotheby's (2004, 2008 and 2010, see Tab. 02, 03), but also splendid circles with GRS-certified pigeon blood ruins were auctioned off in catalogs such as "Ruby an Diamond Ring by Wallace Chan" (Christie's, Hong Kong, May 2009, Lot 1724) (see also Tab. 01).
Over a 10-year time span, the continued publication of pigeon blood ruins in auctions has shown that the general opinion has valued this description for the most precious pigeon blood ruins in the auctions. Launched by GRS in 2001, it was only around 2006 that we discovered a study called "Pigeon Blood" in 2012 from another recognised lab (Christie's, Hong Kong, November 2006, lot 2918) and one of the youngest internationally recognised laboratories to adapt our approach (Christie's Hong Kong, May 2012, lot 3801).
Recently new refills have also been producing pigeon blood coloured Ruby (A Review of Beauty and Rarity of Mozambique Ruby). This gorgeous non-heated pigeon blood ruby has already attracted the interest of the audience and will definitely open a new era in the story of the world's most precious jewel.
Auctioneers of international renown showcase the best they have to sell. Tiffany and Bulgari's first GRS-certified jewels in jewelry were auctioned at Sotheby's in Switzerland in 1998. Cartier's first GRS-certified ruby jewelry was auctioned in 1999 and the range of stamps has been extended over the years ((see Table 01).
Whereas most of the GRS bulletins and sapphire bulletins, a finite number of spinel, peridot, alexandrite, garnet and Tourmalin were released for the GRS, few bulletins for hot stone were included in the catalogue. Sotheby' s and Christie's have included them in catalogs for Hong Kong and Melbourne sales (see Table 02).
GRS residual sorting was used in the catalogs to describe these jewels with our abbreviations H(a) and H(b) in Hong Kong and New York (e.g. Sotheby's December 2004, lots 230 and 232, Ruby and Diamond counterpart necklace). Auctions catalog stated that the jewels were marked with GRS No. 2004-070559, which states: "The ruby is of Burmese origins; reinforced by high temperatures, low residues".
In 2003 a set of ruby and diamonds was sold at Hong Kong Auctions with the GRS2003-02484 Review (lot 619). Between 1996 and 2012, no great interest was paid to ruby heating in the auctions. In February 1998, GRS Type "Royal Blue" Sotheby's in St. Moritz released the first GRS document with the colour code "royal blue" (GRL9712003).
The GRS was quoted and described the gem as "intense king blue". Auctions at Christie's in New York found the oldest GRS reported GRS model "Royal Blue" listed in an online catalog (October 2000, Lot 622, A Sapphire and Diamonds Ring, GRS-2000-04168). Sotheby' s November 2001, lot 406, Geneva, Switzerland, saw the sale of the first GRS-certified premium grade King Bluish Saphir, with an outcome of several million dollars.
GRS 2001-04395 as "The Saphir is of Burmese origin", no reference to the thermic improvement and the specific commentary: "This is an extreme rarity of colour diversity ("royal blue"), outstanding clearness and brilliance as well as a lack of heattreatment. It is imperative that the newly set records have definitely brought the "Royal Blue" brand and buyer's focus to bear on important emerging saphires.
The Burmese origin is mostly supported by the auctions, but not only. The GRS report for Sri Lanka, Madagascar, both hot and off. Tables 04 and 05 show a choice of saphirs called GRS types "royal blue". Today, these new saphires are almost the only sources of the world's most important saphires.
They can also reach the best "royal blue" colour and will predominate the prospective markets after the Burmese spring continues to prove depleted and it can be seen next year, after Burma has opened its door to investment, whether the landmines can be put back into operation after a long disruption time ( "Jewellery News Asia - GRS Expedition to the landmines Mogok Ruby, Sapphire and Spinel").
