Petalite, or a really pale sunstone, would be my guess...
I have a palm sized Petalite stone, beautifully shaped and ever-so-gently blushed in colour, and it cost $11, but that was in a stall at a gem festival where people knew what they were selling... It's not an expensive stone, compared to my other pieces the same size...I'd go with Stilbite (which is a Zeolite) but it does look a lot like Petalite as well - the only thing that makes me think it isn't Petalite is because of how expensive a palm would cost in that size.

The reason I thought it could be either petalite or sunstone is because kduphily mentioned the shimmer, and sunstone has a definite shimmer or sparkle, and can be as pale in colour as this specimen, but my petalite also has a very gentle sheen or glimmer, with a very pale and soft rose quartz pink.... Best wishes... I hope you find your answer kduphily.
