They said that they are selling "Real Jade", does it mean that they are selling Type A jade?

May be or may be not.  Usually they will say that they are selling "Real Jade" or "Real Jade with Natural Color".  They may be selling Type A jade or may be not.  Treated jade (Type B jade) is still 100% real jade with 100% natural color.  It is just not Type A jade because it has been artificial treated.  For more information about the difference, please click here.

How can I tell if I am buying a Type A jade in the market?

If the seller cannot guarantee it is Type A Jade in writing or a certificate issued by authorized institute, most likely they are not a Type A Jade, no matter what they say.  Be sure to buy jade from a reliable source.  For more information about different types of jade, please click here.

You can't tell by naked eye, even experts are not certain.  Special equipment and technique are required to identify.  If you really want to know, bring it to a authorized gemological institute to have it tested.
