colored gemstone certification?

I have been looking for a sapphire engagement ring. I have seen a few that are AGTA certified. Is this a reputable lab for colored stone certification? If not, who is? Does GIA not certify stones besides diamonds?
Thanks in advance for your help,
Amanda

AGTA is a very recognized lab, and GIA also does colored stones as well.

What shape and color of sapphire are you looking for?

Do you think one lab is better than the other? Do the GIA certs indicate the stone's origin?

I began looking for an emerald cut blue sapphire.... but given the range of blue colors I have seen, the shape is much less important to me than the color. I'm looking for the perfect medium blue.

I think they are both comparable for lab reports.

Here are a couple that we have available.
One is a 1.71 ct. and the other one is 2.31 ct. The 2.31 ct. is the one on the left with the wider corners.

AGTA certification is authority certificate,but for gemstone AGL certification is well known. I came across Angara.com while searching for certified gemstones. They provide AGL certified gemstones. Also the website have design your own gemstone engagement ring section, where you can build your own engagement ring with selected gemstone.

Are you affiliated in some way with Angara? Or have you purchased from them?
A quick search of thier loose sapphires shows all are heat treated the & certs they provide are thier own. I did not see any AGL certs.

Are you only looking for unheated sapphires? In an emerald cut it may give you more of a hazy or cloudy look. The heat treatment kind of burns up the silk in the stone making it look more clear.

Well, yes, I had been hoping to find an untreated stone.

You should compare some, unheated and heat treated. I actually think the heat treated look better. It's a permanent treatment as well.
