Claim:
A ready-made gem setting for holding gems having a crown, a pavilion, and a girdle, the gem setting comprising: a base; and two walls that extend outward from the base by a distance so as to extend beyond the crown of the gems, the walls defining a channel between the walls, wherein each of the walls includes a concave groove in a groove plane, each groove facing toward the channel and including a curved upper portion and a curved lower portion, or an angled v-shaped profile, for holding a portion of the gem girdle, such that when a gem including a crown is set into the channel, the upper portion of each groove extends over the crown of the gem to hold the gem in the setting such that, if the gem and channel together are placed in an upside down position, the gem will not fall out of the channel, and the upper portion of the groove has a different radius of curvature than the lower portion of the groove.
