Enhancing adamantine weapons

[LordTrevaine]

I'm sure this has probably been discussed before, but my SearchFu just isn't up to it!

In PFS, please can anyone confirm this is legal (ignoring fame just at the moment) :

1. Adamantine weapon (dagger, greatsword, prosthetic arm, etc) = 3000gp plus cost of weapon (no masterwork cost, as it has to be anyway and this is figured into the 3000)

2. +1 Adamantine weapon = +2000gp. Total cost = 5000gp + base weapon cost

3. Adding an ability with an additional cost rather than an enhancement value, like Transformative (+10,000gp) = +10,000 + 5000 + base weapon cost. Therefore a +1 Transformative Adamantine Longsword = 15,015gp.

Is this all correct?

This checks out to me assuming it is a small or medium weapon.

It's also good to keep in mind that while the adamantine weapon is always available, and the +1 adamantine weapon is also always available, the +1 adamantine transformative weapon isn't, and you'll need enough fame to buy it.
