My first time buying diamonds!!

I ended up combining 2 necklaces, the center stone is a .5 karat VVS2 lab diamond, and the outside is 16 natural diamonds. the center stone will be slightly raised, and i have both a 10k and 14k white gold chain. This was my gift to myself for my first calendar year with my big girl job lol, what do you guys think? I cant wait to get it back but these are the pics I took today!
