As long as it shows some red, it's a rubellite, hence the meaning of the name "ruby like". Red is a dark toned pink. Whether it holds its colour or not is altogether a different matter.

Take a look at it in incandescent or other indoor lighting. It may tend to go brown.MakingTheGrade|1301021237|2879676 said:Barry tends to shy away from the "marketing" terms, which I appreciate as it makes things less confusing. He typically just lists the stone type, and sometimes the location if he knows it.
When I asked him, he said it looks amazing in natural light. What kind of lighting does most tourmaline lose its color in?
I don't really place much importance in the labels, I just bought it because the color jumped at me, but I was still curious.![]()

I wasn't sure that I believed this and so got out a box of rough pinks and red tourmalines and had a look. The end result is that you're right , some of them do turn brownish under incandescent light. After a bit of messing around with this it turns out that those pink/red tourmalines which turn brownish to some degree are those which have a green tint, typically on the A-B axis. The increased red/orange color in the incandescent light interacting with the green component in the gem is perceived by our eyes as brown. Cool. I think that the reason that most rubellite's don't turn brown is that they have the same colors on all axes or pale cross axes and so any brown just gets overwhelmed by the increased red displayed in incandescent lighting. The downside is that I have a few distinctly greenish cross axis pink tourmalines that just became mineral specimens.![]()
Thanks for the observations, Michael. That makes a lot of sense.Michael_E|1301073574|2880126 said:tourmaline_lover|1301062187|2879945 said:Did he say how it looks in incandescent light? Flygirl is correct as pink/red family tourmalines tend to "brown out" in incandescent light.

"...There are red and pink tourmalines in many nuances, which include a tender pink, a fine shocking pink, an intense violet and a bold ruby-red. However, only a few of these are entitled to call themselves 'rubellites'. The name comes from the Latin 'rubellus', which means reddish. Rubellites are not merely red or shocking pink tourmalines. There is an important criterion for this especially beautiful gemstone, and that is the way its colour behaves in daylight and artificial light. Many gemstones change their colour depending on the light source. A true rubellite does not. It shines just as intensely in artificial light as it does in daylight. The colour of most other pink or red tourmalines, by contrast, displays a more or less clearly visible tinge of brown in artificial light."
