彩虹透明寶石 14 件組 by Papoose Toys by Colours of Australia

The light catches these gems beautifully, and the 3cm size is perfect for little hands to build with. The colors are rich and even, though I do notice the tiny notch on each one from manufacturing—it's barely visible and doesn't affect play at all.

My daughter immediately started sorting them by color—the 7 different shades are so vibrant and clear. I was a little worried about the small notch from manufacturing, but honestly it’s barely noticeable and doesn’t affect how they look or play. Perfect size for little hands to stack and build.

The gems are a nice size at 3cm and the colours are exactly as shown, though I wasn't expecting the little notch on each one until I read the note. Still, they're sturdy enough for sensory play and the kids don't even notice the mark.
