I am VERY grateful to StoneAlgo for saving me from a would-be terrible purchase. Highly recommend!
The cut score was a terrific way to hone in on the best candidates when faced with the overwhelming number of options available online.
By using the StoneAlgo calculator, I was able to find the best cut diamond at the best price. My diamond is breathtaking.
