You can't go wrong with WhiteFlash.

I'm a repeat customer. Engagement ring, pendant etc. Always a top notch sales and customer service team. The customer service is impeccable - from recommendations - setting and shipping security, etc. Can't speak highly enough for the organization. When I was shopping for an engagement diamond - I even got to speak with one of their gemologists who pulled the stones I was considering from inventory - examined them and discussed the pros and cons with me. They have wonderful stuff and the craftsmanship is stellar.
