    Hi CS-ers, am new go colored stones and awful at reading photos so will really appreciate advice for this pair of tanzanites that are calibrated 8 mm. I’ve read that tanzanites are fragile so I’m looking for earrings. What do you think?

    If you like a touch of purple they're fine, but there is higher quality "sapphire blue" tanzanite on the market, but likely at a higher price.

    The tanzanites are a bit too purple and it’s likely you can get a better price for these. Tanzanites can be obtained at really good prices from Tanzanite wholesaler’s rather than the vendor you are using because they don’t specialise in tanzanites. Try top tanzanite in New York. You’ll get the same colours at a lower price or a higher quality pair within the same

    For $900, I would want them to match better and be a little more of the blue. Plus, if you aren't happy, depending where you are, you have to ship them back internationally.

    Thank you @prs, @Gemobsessed and @MrsKMB!

    These are not heated so will that account partially for the higher price (plus is there a cutter premium?)?

    Also I am keen on trichroic tanzanites which from what I’ve read is only in unheated stones? Or can you still see the blue/violets/reds in heated tanzanites too?

    Does anyone know where else has nice 7.5-8mm round pairs? I’m cool if the color is not super saturated blue which I understand is the top quality color. I’m quite partial to violetish-blue (and also more wallet friendly haha).

    Thanks so much for all your advice and honest opinions.

    Also for my learning benefit is there any window on the pair of tanzanites? Sorry so many noob questions... :geek:

    Unheated tanzanite is one of the few stones left on my wishlist. I think they are beautiful! I absolutely love it that they are pleochroic. I think these are underrated. I do think $900 for the pair is high. They should be more around $550-$700. If you are looking for the bluish purple, saturated tanzanite, this pair is not it. Those are heated almost 100% of the time.

    People wear tanzanite in rings all the time. I have one and my mom has two. You just can’t wear it as an everyday ring. Also, you need to take it to a jeweler who is used to setting soft stones.

    Yes I also like tanzanites cos of this pleochronic thing that they have plus I love the violetish blue colors too.

    Am not so much into rings I realize as I can be so careless though I’m still very keen to get a diamond ring upgrade for daily wear... anyway was reading about micro pits and other concerns so I think best that I stay away from tanzanites in rings... I do love earrings so I think studs and drops will work well for me...

    I think I found an example of what I would really love to have...

    Not a colored stone expert (at all!) but wanted to say that I love that last pair you posted. I love seeing the blue/purple! The
    cut looks amazing to me!

    The first pair is unheated course in one direction (left stone 08:00 - 02:00) green - heating will not remove this. The variety is sometimes called „mardi gras“ in trade. Nice cutting - price a bit high.

    Middle pair - a bit greyish?

    Last pair looks a bit unreal - photoshopped?

    I think they are beautiful but your preference is the main consideration. I also think that with colored stones there is less of a "PS quality" than members place on diamonds. Diamonds are mainly white stones that PS members judge by the 4 C's. But colored gemstones are different. There are so many individual preferences in color. We do have trade recommendations based on what is the highest valued color and saturation for colored stones which gives us a ballpark range for cost, but individual preference on color should be the main consideration when buying.

    Oh, you want the pleochroic! I still stand by the price being high and returning them might be a pain. I first saw those a few days ago, and really liked the colors, but I personally like stones to match better. That's just me. You need to get what you like! If you really like the first pair, reach out to the seller and see if he can do better. Usually, he will come down in price if you're really interested.

    Sorry, I find the original blue-blue tanzanites really boring compared to the unheated mix of colors that defy descriptions and are so variable that even the same stone looks different all the time. I had the pleasure to study an unheated purple-pink-green-blue-all-else colored 5 carat and the seller had to pry it off my hands (since I couldn't afford to buy it). It was a revelation of color-variety I had never dreamed of. If these are the gems that are heated blue, it is clearly a loss to the world, but perhaps it is the brown ducks that go for treatment?
