Anything is 'worth' what someone will pay you for it.
On the Fancy Diamonds site, we found a .81 carat natural Fancy Green diamond with a VS1 clarity listed for about US$45,000 (the smallest we could find).
If you have a green diamond to sell, best practices dictate that you pay for a certificate from the GIA organization, to verify that your diamond is a natural green stone. (There are several shades of green, and a myriad of green-combination colours of diamonds.) The certificate, as well, will verify the carat weight, the cut and the clarity of the stone. With these details, you can value your stone.

Anything is worth whatever someone will pay you for it. Best practices dictate that you pay for a certified gemologist to document your diamond, as to its colour, carat weight, clarity and cut. This will help you establish a fair market value for your diamond. As you can see from the link, below, there are many shades of natural 'green' diamonds.

Any diamond is worth whatever someone will pay you for it. Z4 is not a common notation that describes a gem-quality diamond.
I think you are asking if a natural clean diamond is worth as much as a natural diamond that is Not considered clean? The answer is no. A clean diamond means that it is clear from imperfections. Now this can mean clear to the naked eye, or clear under a microscope. Of course the diamond that is clear under the microscope is much worth more than a diamond that is only clear to the naked eye.
Your answer depends on the quality of the diamond you're buying/ selling.

A diamond is worth what it's worth, regardless of where and how it's set in jewelery. A diamond's worth depends on its carat weight, its colour, its cut and its clarity.
