Hi- I love this ring but need to be able to swap

When you go into ANY jewelry store you see many,many styles and costs of different pieces of jewelry with the stones already set. ask the sales person to show you 2 or more pieces with the same amount of stones, can you see any difference in the flash or color of the stones, next, walk or turn away from the lighted showcase[s] maybe shield from the lites from above too, Now surely you can see the difference. Next ask for a loupe from the sales person hold it up to your eye [1/2 "from eye] bring into focus by moving the piece in or out from the loupe. now you will see the importance of cost comparing from different stores. The lighting plays a major role in displaying of jewelry.
