That has beautiful colors! It can be difficult to date these, especially from just a photo. I can make a guess that it is more on the contemporary side of the 20th century, post WWII. The fringe on your shawl is plain and straight and the antique shawls usually have more intricate fringes with varying degrees of fancy braiding, tassels, thicker fringes, or longer fringes, etc. I just get a more modern era vibe from your shawl. It is lovely regardless of age.
I will wait to see what others think.
