Can you upload the photos to the posts? The mods will pull your links--PS doesn't allow links to other image hosting sites.
You can also post a link to the vendor's website for people to look. Just make sure the stone is on hold first so that it doesn't get poached by a lurker.
The diamond looks good Ted from what I can see, I can tell who the vendor is and they will be honest about whether it is eyeclean to your standards or not. The images need uploading however as it is against policy to link from those sites.
