Outline & Structure: Need to write a content page of a Buying Guide for a Diamond Ring retail website. Should be written with SEO optimization in mind. Use key wards. I will provide some but need advice from the writer too. Therefore someone with good SEO experience is preferred for the job. Expect this to be between 700 to 1200 words.

Writing should be in very good UK English and grammatically correct but simple and engaging.
First para should give a nice little, catchy and inspiring few lines explaining why people buy Diamond and especially as a way to express love and a best way to show your love.
Second section should address what to look for without being ripped off by high streets sellers. This should mainly address the buyers new to Diamond.

Then briefly explain 4 Cs of Diamond. Explain with quality pictures. Explain what is important to the buyer in selecting a diamond.
Each 4 Cs should have a link to ‘learn more’ section that explains this in more technical terms each topic. Each section will be 500 words i.e. 500 x 4. (This will be in the second phase of the project. If you do a good job this will automatically come to you.)
Extra notes: I can give you links to some useful sites to get an idea
