What online store to buy diamond ring?

Check out Hello Noemie. They have several carat sizes of eternity bands, in both mined and lab diamonds.

Personally, for an unbranded everyday piece of jewelry, I would go for lab diamonds and save some money. It’s not like these types of pieces will increase in value over time, so I’d spend the smallest amount of money that would get me what I want.

I am planning to get new diamond studs soon and will be getting lab diamonds.
 
Costco has well priced and high grade diamonds. I’m not fond of lab grown.

Another vote for Costco - they have some beautiful diamond eternity bands in a range of carat sizes and at unbeatable prices for the quality. I have two 2 ttcw bands in 18k yellow gold and platinum which would have cost triple the price from a high street jeweller here in the UK and am thrilled with them.
