What other sites are like Polygon? Looking to start a websit

[oxcorp]

Hello All,

I am new to the site.

I am looking to set up an online diamond site, I have been looking at using Polygon. Would love to hear about other services that are similar.

I have a good database of clients to market to and will be concentrating only on the New Zealand market.

Any help would be much appreciated.

Thanks Ox
