I think it’s a star sapphire?

I posted this in the antique forum before I thought to post here. This was found on EBay looking for moonstone but it has a six ray star that moves depending on the light. I’m pretty sure it’s a star sapphire but wanted to get some expert input: TIA!

not saying it isn't a pink star sapphire, but it reminds me of rose quartz, which when cut in cabochon can exhibit asterism

It’s pretty! Can’t say if it’s a star sapphire. As Mary said there are some other gems that show asterism.

@marymm @Dreamer_D thanks for your thoughts, maybe I’ll get it looked at but just wanted to see what folks here thought, I know identifying gemstones through pictures is not really possible. Still it’s pretty and I’m happy with it whatever it ends up as.

Yes. Here are some star rose quartz spheres:


These were not sold as star rose quartz, just as rose quartz spheres at rock shops, max price $15. I used a flashlight to spot the starry ones. If I'd stuck to rose quartz, rather than 'graduating' to star sapphire, I be a lot richer. Note that 'rose' quartz isn't always very pink - see the lower left and centre stones.

As I recall, @Glitterara scored a star sapphire sold as moonstone:

Thank you, dreamer! I couldn't believe my luck when I found it--the seller told me it was "a star something, I forget what." I said, "Star sapphire," but she said "No, that's not it--star moonstone, I think," and sold it to me for not much more than the value of the gold. It's one of my very favorite rings.

But hers was pale blue:

Adding my latest star sapphire, an Edwardian stickpin conversion. The pin had already been snipped off when I got it; my jeweler found an empty antique ring setting that fit it pretty well to add to the back. It's maybe 5 or 5 1/2 carats, nicely transparent blue-gray, with some zoning (a transparent stripe). The star is sharper in person--it's hard to get a good photo.

As always, you can't tell from pictures, but star rose quartz seems more likely for yours. It's definitely worth having checked.
