Q&A: “Officially scared” about buying a diamond — help!

Well you officially scared me from buying a diamond, so many things to know and still you may not be getting what you think or even over paying. Im skeptical about this whole process but seeing that like most people in my situation; i have no knowledge of diamonds, really what do i have to lose by asking your help!
Im looking at buying a loose diamond because im buying the ring seperate. I was looking betweem 5,000-6,200 for price, was looking at ideal cut, F-E colour, vs2-vvs2 clarity, Size came depending on that stuff and where that put me for cost (but probably between .78-1.00).Id rather go really nice diamond and smaller carat, then big and not shiny.
I need your help cause i know nothing really. I want the best sparkle and want the other catagorys to be good enough that it cant be seen with the eye. Ive never looked at a diamond so dont know which colour is going to be noticably yellow and what inclusions im going to be able to notice. I want the best ring but dont want to pay for something that isnt noticable without a microscope!!Like is there a difference between ideal and hearts and arrows? I want it to sparkle but dont want to pay for something that isnt even noticable to her or anyone else. If you could help me cut in the areas that dont matter as much and arent noticalbe but would save me money so that i could get a bigger diamond without sacrificing the look and beauty of what she will be wearing i’d be so thankful. any help would be great, if you read this i thank you for your time.

Setting is Solitar,platnium, (petite trellis solitar from blue nile to be exact)and she wants princess cut diamond. Yes thats exactly what im looking for, something that shines and is sparkly but is clean and white. I dont care about how perfect it looks under i microscope, but rather flashy and no imperfections noticable to the eye. Any help you can give would be great. thx again

Ira, I emailed james allen and got pictures of the other diamond you said to look at. There looks like brown marks in the diamond, can you take alook and tell me what it is and if its a good clean diamond. Id rather go with a a higher colour like H then G, and have a smaller size stone. So if this one checks out with you ill probably buy it. thx

Its the same picture you sent me. The link is on the page u sent me. if you scroll down on this email and click the link the picture will come up.

Hey Ira, Thanks for all your help with everything. It’s a very kind thing you do helping guys like me with such a expensive purchase like a diamond with no clue with what we are looking at! I purchased the diamond you suggested so i look forward to getting it. With the little research i have done it looks like its a nice diamond and should be saving at least some money then if i were to buy from a retailer, or at least i hope so? Thanks for everything you do, and from all the clueless guys out there like me; we thank you for your time and expertise in such a difficult decision that we have to make.
