The sapphire is a precious gemstone, and a variety of the mineral corundum. It’s also the birthstone of people who were born in the month of September. Let’s face it, September is one of the best months of the year, because it’s not quite summer, and not quite winter yet… It’s just right in so many ways. With all of the beautiful gems on this goggle, and with the blue lens, not only will your eyes look like sparkling sapphires while you wear them, but the people around you will thank you for looking so awesome.
