Hi Eri
We have both genuine and simulated stones.
All genuine stones are unique and come in various colors. Some are lighter than others and, depending on the stone, some will have more inclusions. They are also very difficult to photograph and accurately depict on a website
Simulated stones are created in labs so they wont have the same variations of a genuine stone.

I hope this helps.

Natural stones are just that. Natural. They are very difficult to get twin stones, as everyone is different. That being said, for a more cookie cutter twin stone, it might be better to get a simulated/lab created stone. I have bought Natural Emeralds for years and I have never had the stones look EXACTLY like the photos or like each other. That is what makes the difference between Natural VS Simulated. My personal opinion is to buy the Natural Stone and enjoy the differences in the stones!
