Davi_el_mejor: No. The cut stone is not from the rough of my avatar which is a 53 carats. This 2.5 carat spinel is much stronger red and flashy (even the picture was taken under fluorescent bulbs). This is the second time I encounter this kind of red stone despite of many had been passed through my hands.
Enerchi: Thank you for the term "I Love Lucy" red lipstick. That is the purpose of my post: What are the other terms would you be using for this color? Locally the people call it "traffic light" or "flag" red.
Antoine, thank you for posting your lovely spinel. The saturation is amazing, and the cut looks very good.
Just out of curiousity, how much does the color shift in different light sources (sunlight, flourescent light, incandescent light)? It looks like it has a slight orange modifier, but I realize it may look different in real life, and under different lights.
Also, does this spinel, or Thai spinels in general, have red fluorescence?
Pregcurious, this spinel is from LucYen, Vietnam. It can be mistaken for a pigeon-blood ruby under daylight, indoor it shows more orangey. It happened that some rare specimen are strongly fluorescent, especially under long UV. These stones normally beam out across the room in a late afternoon.
