I recently got interested in the domain name buy and sell market. I quickly noticed that there are tons of great keyword specific domain names available in the extension .org.uk.

I recently purchased these 2:
diamondrings.org.uk
diamondearrings.org.uk

I have a long list of other good ones that are available. Can I get some feedback on whether this is a wise investment opportunity or not.

Thanks in advance,
Mike

haven't heard of any big sales of them, ive noticed some nice ones in the past but wasnt inclined to buy them.

You can give it a shot and see how it goes, but I wouldn't try and invest more then you can handle. For the most part though most high quality domain names are already taken. Only way for them to become high quality is then if they were once owned by a very successful website.

or you build them and make them popular.

with enough time, work and money, you can make any domain valuable. 'how much" is the key question.
how much to make it worth how much?
to be real valuable requires some major brand recognition.

just don't invest so heavily you hurt yourself if the domain goes no where.
most don't amount to much.

The problem is that org.uk is a tld not so researched.
