My only consideration for this particular purchase is that it is from a lot and I don't get to select the specific gem I want. However, I trust GemSelect and they all look good in the picture provided and are all the same approx. size and weight. My only real concern is the star in the star ruby, as I want one that is both clear and shapely.
