This is an Abalone/Paua 4-sided obelisk. There are rectangle, square and triangle tiles overlaying a 4-sided obelisk base of acrylic, lucite, stone or glass, I am not sure which. It is highly iridescent with blues, greens, pinks, pearls, and browns. The photos do not do the iridescence justice. When it is in daylight or other bright light, it is highly reflective and the iridescence pops. There are no chips, cracks, or missing pieces. There is normal abalone/Paua undulations in the tiles. It is approximately 5 3/4" tall and the base is 1 1/2 " by 1 1/2". The edges are sharp and it comes to a sharp point at the top. Three of the base corners are sharp and one is slightly rounded. I collected obelisks at one time. I am downsizing and am selling most everything. Non-smoking household.
