Now you are looking at off-brand labs - you need to stick with AGS 0 or GIA XXX stones. Run the numbers through the HCA https://www.pricescope.com/tools/hca and request idealscopes for those scoring under 2.
Or post your budget and goals and let us HELP you, for pete's sake!!!!!
If you think you can bet a better deal buying a diamond graded by one of the off labs, think again.
Color and clarity grades dramatically affect the price, even when you can I can't see the difference.
That's why it's really important to be able to trust the grades issued by the lab.
A diamond that got grades of F VS1 from a flakey lab may get grades of I SI2 or worse from a reputable lab like GIA or AGS.
So while you think you are getting a good deal buying a diamond graded by Blah Blah Blah Labs, you are almost certainly over paying compared to what the price would be for the same diamond if it was graded by GIA or AGS.
There are no bargains with diamonds, only ripoffs of poorly-informed customers.
