More photos

Thank you for the reply Sharafi.
Can you tell if jufti knots were used on the last two?
And I'd like to know what they are worth. I can't find any
similar online for comparison and of course I'd like to know if I paid the right price.
Thanks again for your help.

Thank you for replying Little Persia.
When laid side by side the knot density on the two Nains appears slightly tighter than the Isfahan.
I agree that the workmanship is better on the Isfahan, no knot out of place, silk foundation with very crisp details. The number of colors is more than double that in the Nains, which I think are on cotton.

Not actually seen the knot count images, was just going on the face of the rugs from the photos and to me it looks like more commercial 9LAA quality (basically going by eye); the Isfahan looks clearer which perhaps suggests better workmanship even if it's not as fine.

I don't doubt it's fine, it's plain to see. I was basing my comments on home15.jpg (I didn't open every image, just a selection), to me on the face or the rug it looked fuzzier than the Isfahan.

Thanks again Little Persia,
Not the best photo.
The rug measurements in inches are:
Isfahan 92"x61"
Blue Nain 81" x 51"
All over Nain 77.5" x 51"
The Nain signatures look very similar if not exactly like one confirmed as real on a site showing one real and several fakes, but I leave that call to the professionals here.
From the discussion, no debate so far, the Isfahan is a confirmed Enteshary. If the Nain signatures are genuine and new, as Sharafi has stated, what are these three rugs worth?
Will I need a rider on my insurance or do I have nice new doormats?

Jufti knot needs an experienced eye to see because it is basically taking a set of two warps instead of one to knot across. I am almost sure that the Nains are Jufti knots because the use of this kind of knotting is prevalent in Nain. In terms of how fine it looks it will not look too different but it is less dense so it will not wear as well.

With all due respect to Little Persia I think they are both 6la Nain. They are quite fine and I think they are Habibians. As I said it is not the father that controls the weaving anymore and the quality is not the same as the Habibians that were being produced about 40 years ago.

Having just come back from Iran I can tell you the the price of these goods have rocketed there, so my valuation is based on what is available here in the shops and to some extend the pricing in Iran.

Your Isfehan is about $7500 and your Nains about $6000 each. I certainly would not be surprised to see them at about 20% higher price than this in some of the shops.
