Some people like some people dont like the use of pink ruby instead of pink sapphire... But on a scientific way the coloration of a ruby is due to chromium, the coloration of pink sapphire also. There is nowere a clear definition of what is the difference (Usually around 1% of chromium gives red and 0.3 gives pink... but what will we say for a stone with 0.75 or 0.8?) and the fact to say that the stone have to be red is a little bit reductive: red under which light? Under London cloudy sky or under Singapore Bright sky? Some stones looks red in London and Pink in Singapore... So? This is why I dont see any problem in the use of "Pink Ruby" or "Pink sapphire" An other thing: When speaking with crystals or star stones, there is no pink sapphire: only ruby... To my opinion as I'm working in a gemological laboratory: "pink ruby" is completly acceptable and less confusing than "Pink Sapphire". but some people love "pink Sapphires"... Anyway!

CGUY Rough Rock Total Posts: 58 Last Post: 3/27/2005 Member Since: 5/29/2004	yea !! Rubies are red but this is really pink in color . so we can say its a pink sapphire .. I have put this ring on the scanner and scanned it . As far as hardness goes for ruby its 9 and for sapphire also the hardness is 9. Lets looks at another pic of my collection of Red Ruby . Now this is a "Red Ruby" and its red in color but that ring is pink in color. Plz look at this link to see red ruby http://coolguynamek.bravehost.com/red.JPG Coolguy

strmrdr Ideal Rock Total Posts: 23,296 Last Post: 10/9/2009 Member Since: 11/1/2003	Ruby is red colored sapphire. The red color is more highly prized so it has its own name and a price that goes with that name over the price of sapphire. My problem is with calling pink sapphire a ruby is that there is a price premium for ruby. If its priced for what it is I dont care what its called but all too often sellers are calling pink sapphires a ruby so they can charge more for it. This is not being honest with the buyer. Nothing will convince me to stop spreading the word on this :} ........... Karl has joined the diamond trade and is now posting as Karl_K

Nicrez Ideal Rock Total Posts: 3,230 Last Post: 10/21/2009 Member Since: 1/21/2004	Ahhh Storrm, always raising a bit of dust. eh? In the US, GIA and quite a few others will only allow certain reds of corrundum to be considered "Ruby". Some dealer, especially in Asia, will debate over pink sapphire being "pink rubies". It's most likely the same as seeing art one way or another. Mogok IS right about the concentration of Chromium, so it's a matter of what DEFINES a Ruby ( color or chemical content) to one person, versus another (and who you are selling it to!) The ruby that you posted seems to have a Burmese saturation. Thai and Afghani gems tend to be darker and less saturated, so that would be my guess of it's origin, possibly even Tanzania as an alternative. Interesting to have it appraised to see it's origin, and it's classification here in the US. I assume it will be considered by most as Pink Sapphire here. I also suggest that when selling (if ever) make sure it's to someone who prizes a Pink Ruby over the Pink Sapphire. Actualy, natural pink sapphire is not very common, and if rarity dictated price, pink sapphire would be more expensive than it is. According to GIA, Pink Sapphires are categorized as ranging from tones 2-5, and from saturations ranging from 1-6. Also I believe that a pink sapphire may show a light orange-red florescence of a weak orangy red. Ruby I believe has strong florescence, as well as their spectra MAY be different... That's what I get from the GIA books. So, depending where you get it certified, you may have a difference of opinion... Good luck!

Vincent Pardieu Cut Rock Total Posts: 408 Last Post: 3/7/2008 Member Since: 1/21/2004	Hello... Ruby and pink sapphire spectrums are the same as their spectrum in both cases is only due to chromium. The only difference between them ( Except the price...) is the chromium concentration. Now some rubies and pink sapphire does not have a pure chromium spectrum as they can host some iron, manganese, vanadium, titanium.. Iron if present is sufficient amount will cut the fluorescence and make the stone more brownish as in Thai and african rubies or if there is some titanium present and if the iron is in the correct Fe2+ state the stone might be purplish... Rubies and pink sapphire can go to orange and purple due to the presence of other elements in addition to chromium. Its not easy to put a barrier between ruby and pink sapphire or between ruby and purple or orange sapphire... The controversy is permanent and rampant. Pink ruby is just more scientifically correct. So why not? Even if I prefer the sound of "pink sapphire" on a personal feeling. Vincent Pardieu, "travel addicted gemologist". www.fieldgemology.org
