What are the most desirable colors for these gemstones?

[RockHugger]

Honestly, I like the different colors of stones. In tanzanite, I LOVE the green/blue type. I have a couple that change from green to blue when you shift them and they are my favorite. It veries by person honestly. Technically, a dark sky blue is best of sapphire, grass green for emerald, and deep velvet blue for tanzie. I dont like those colors o n any of them LOL.

what is not desirable in a blue sapphire?
if the blue sapphire has a secondary greenish hue, that is not desirable right?
grey tones are not good too right?

Any tinge of green is not desirable in a blue sapphire, same with yellow. Grays are also not raved about because it means that the saturation is lacking.

These various gems were all described as ''stop light'' or ''pure red'', but I think they all look pretty different, lol. Although a part of that might just be photo taking skills (these are all different vendors)

Personally I like the color of #1 best, whatever it''s called!

This is what I would call a ''stop light'' red!

Looks plenty red to me too.

Found this but still I am not 100% sure if this is a good velvelty blue for tanzanite or is it too dark? (still training my eyes!!

)

The stone possibly has a slight window. Colour wise, the tone appears too dark and not saturated enough.

since someone talked about stop light red
could you give me your opinions on this colour?
what do you guys think?
AJS 0.64 Spinel
Stop light red enough?
Hows the price ? is about 155usd/ct

could someone refresh my memory on what are the $$/ct for different grades spinel and blue sapphire?
Wildfish has a list of $/ct prices but i just wanted to gather people''s opinions

I agree. The other thing is that it''s just a tad too grey. It''s dark (and too dark in some areas) BUT the photo has been taken from an odd angle. On the plus side you can see that there are areas of purple peeping through. Is it possible to ask for more photos? Perhaps one on the hand? That would give a better idea of how the gemstone might look once set because if it''s dark now, without being set, there''s a very real possibility that it will become too dark once set.

With a very good Tanzanite, you don''t want to see any hint of grey. You want it to be a rich, warm, almost velvet colour if that makes sense.

I don''t know if this helps but compare the one you''ve found with the pictures I posted above. Can you see how the one you''ve found is overall much darker and doesn''t have the areas of intense blue?

LD, it helps! Now that the pics are together I can tell the difference so easily! And I can see what you are saying about the touch of grey in the dark stone! Thank you!

Chrono, thanks for nailing it! I needed that confirmation!

I do not intent to buy this stone, just wanted to test my eyes on what I am seeing, as you can see I am not 100% there yet!

I will be in Cape Town, South Africa early ''10 and I might have the chance to shop for some african stone like tanzanite, so I am trying to start training now that I get it right colorwise. One more Q, what else do I need to know when I am buying in SA? Any advice? Or anyone else knows?

Yummm, I so adore that emerald cut tanzanite!

My tanzanite has a touch of grey, but it's unheated, so I don't mind so much. Still, I'd LOVE to have something the color of that emerald one day.

Have fun in SA Megeve!

Megeve - glad it''s helped. Why don''t you have a look at Multicolour.com as they have tons of Tanzanite. You can see the difference in all the colours on there. There''s a fabulous bluish violet one on then at the mo but you can also see the lighter colours etc. Lapigems is another good place to look - typically their gemstones are very highly saturated and some can be a little dark BUT on the whole they''re lovely.

MTG - Glad you like it! Heating Tanzanite tends to drive off the brown but many stones (heated and unheated) retain grey so I''m not sure that the lack of heating is responsible for it.

MTG,
I think your tanzanite looks great, especially for an unheated stone.
