Pigeon Blooddove blood
e. have a primarily reddish colour. In other words, reds must make up at least 51% of the colour mixing.
It' not a ruby if it'?s not the colour of a ruby. Every member of the precious stone familiy Korund, which has a different colour than the one of colour reds, we call Saphir. The ruby may have one of a few possible secondaries. They are: rose, lilac and amber. Violet and oranges are the shades right next to reds on the colourwheels.
You' ll never find a Rubin with a little bit of alternate colour. Pink, a lighter, less richer colour is also possible. Its subtle colour or pigeon blood shows a violet second colour. There are two good causes why violet; one historic and the other on the basis of tint. When Vincent started to study gemmology in Burma, he found a trader who told him about "pigeon blood".
Lilac is a colour tone that lies between the colours blues and reds on the colourwheels. Myanmar's gemstones are in a very deep golden age. So, when a crimson ruby is captured in amber, the amber of the diamond removes the blues in the crimson and leaves an almost visual clean reddish (pictured above a 1.63 carats precious stone grade old mine Burma with a GRS "Pigeon's Bloom Certificate).
The Burmese target is therefore always bright green! Colour Science shows that the colour reds achieve their optimal level of satiety (brightness) at a rather deep shade, about 80%. Considering that 100% clay would be purely buck, 80% are quite obscure. On the other side, the colours rose and purple achieve their optimal level of satiety at relatively bright shades.
Rosa obvious, since by nature it is faler (less bright). Achieves its optimal level of satiety at 30-40% Ton. Violet achieves its optimal level of satiety at approx. 60% pitch. Optimal reds and violets blend quite well and are both in darkness. Violet, unlike rose, does not thin down the colouring.
The light colour of the reds would be brightened by light colours such as bright green and yellow and thus reduce the overall colour range of the reddish-rose or orange-red. Violet strengthens the diluted reds, oranges and roses. A few experts like a little too much or a little tangerine. This is a good point when you look at the effect of lemon in it. However, for good historic and scientific proofs, the colour is not pigeon blood.
Vinza (Tanzanian ruby) had come and quite disappeared, Mong Hsu had ceased to produce, but Mozambique had become an important new well. This necessitated an overhaul of my section on rubies. It is known in the industry as Montepuez Rubin. First picture above is a 2. 09 karat old Mogok nature-rubin.
It has a slightly cleaner reddish colour and shows less crimson than the second one, a 1.63 carats gemstone from the same area. However, both evaluated "pigeon blood" from GRS, Swiss Lab, Bangkok. This is the place that dates back to the Bronze Age, where the initial rocks were quarried when the word pigeon blood was first used.
Hsu rocks can certainly be pigeon blood colour, but since we are discussing a historic concept, I thought it would be best to use old mine artwork.
