Post subject: | treatments - before and after |
Sorry if this has already been posted, but I'm just stunned by this website! http://www.thenaturalsapphirecompany.com/Sapphires/Education/Photos/ It makes lack of treatment even more important to me now. P. S. I thought heating alone could never alter the color so drastically as BE diffusion, but I was obviously wrong! |

great link, m4!! definitely an eye-opener, eh? i agree with you about how lack of treatment is now more important to you!! if i ever purchase a sapphire or ruby, i would like to have a laboratory gem report as well as a county of origin report. i hope you don't mind but i posted it in the "synthetics and treatments" section on GO for my5fireflies under the "Lattice diffusion corundum advise" post. love the term, "sandpaper quality," for very low-quality corundum, lol!! |

No, of course I don't mind you posting this like elsewhere, as it's very educational and it's a shame more people doesen't know about these things before buying. It's probably a very similar case with most other gemstones, i.e. not only limited to corundum varieties. P. S. Just imagine an ad that goes something like: "...this exquisite, sandpaper grade sapphire is accented by ten shimmering frozen spit diamonds..." |

hey let's not forget the vast majority of sapphire IS heat treated, and you will pay big BIG bucks at thenaturalsapphirecompany for their stones. |
