According to Pinterest, it is Summer Waves quilt by Melinda Nentwig, pinned by Kathy Timmons. I haven'y found an actual pattern yet.

I believe the quilt is made of Snail's Trail blocks (the curvy ones) and some other simple blocks, set in a medallion setting.
edited to add: Found it. The center is different but this is the pattern.
