I really like the font(s) you've used here (#22) with the flourish embellishment. I would prefer to have a pendant or earrings over a ring in the graphic.
So, upon further reflection, I think just a shimmering stone would work! The name Tula Stone comes from a mythical stone which embodies the divine nature within humanity!
I like the layout of #24, with the graphic to the left, and the cursive font, but I prefer to have the two words "Tula Stone" be in the same font. Still liking the glimmers!
