Q&A: Help choosing a 1 Ct. Oval Diamond for a White Metal Engagement Ring

Saw an oval diamond online and it appears to be a great deal. Wondering what your thoughts are on this specific diamond. Like most guys, I know nothing about diamonds or what to look for. I’m reading through several articles on this site, but I’m not sure I’m going to be prepared just by reading a few articles.

Thanks in advance for your help. 

 Do you think they sell anything worth buying? What ratio should I be looking for so I understand what too deep is? Everything appeared to be in good order when looking at the 5 C’s. Just shows you how naive I am. Any suggestions? 

 Thanks for helping me avoid this mistake. Where would you recommend that I look for a decent oval diamond around 1ct? I live in the northeast and would welcome any recommendations locally or online. Thanks in advance. 

Just getting around to making this purchase. I was looking to up my budget to about $5,000 for the diamond. Can you make recommendations on where that extra $$$ should be spent. I found this diamond and wanted your opinion. is it worth the extra money?

Thanks for all your help. 

 I’m going to be making this purchase next week. I’m actually selling a car that’s going to pay for this ring. I’m hoping it’s still here in the next few days. If you think there’s anything better than this one that’s popped up let me know.

You made this purchase much easier for me and have educated me considerably. Thanks again.

I actually pulled the trigger on this diamond and bought it this weekend. Would you recommend a platinum or white gold band for this? I’m getting a very thin band. Trying to replicate a picture of diamond that my gf really loves:

Thanks in advance for your help with selecting the appropriate band.
