A couple of years purchased a very fine diamond ring from this store.
Update...
Don't know why they don't seem to have the fine diamond engagement rings in the stores in Phx & Glendale.
My diamond I purchased was an F color, with xlnt cut & it was called a regal diamond.
They might still have the fine diamonds available if you inquire or go online and look for a quality diamond.
Lately I've noticed that Costco & Sam's carries "I " color diamond engagement rings which is a lower quality color.
Here's is a hint about diamonds the whiter & clearer the higher the quality .
For those interested in quality.
In my view, you can't go wrong in quality in regards to diamonds which is my experience.
And most women will love it since DIAMONDS are a girl's best friend :)
