Topaz Price

Hi,
is there anyone who can guide about the price of a Brown Topaz 389.00 carat…Modified round brilliant…it is certified.

Brown topazes are relatively common. According to our Price Guide listing for topaz, stones of this color and size could run from $20 to $80 per carat. Cut quality and clarity will have the most impact on this stone’s value. Any eye-visible inclusions in a brown topaz will lower its value.

Thank you… and where i can go or where i can send the pictures for sell? I would like to sell,but first i wants to know quality and price
