California Coast Cyan Blue Sea Glass
Actually, this sea glass is somewhere between blue and green. It's an equal mix of both, a color known as cyan. Is it turquoise? Perhaps.
The word turquoise (from the French word for Turkish)comes from a blue/green mineral of that name. However, turquoise leans slightly towards green.
It is accurate to say that it is cyan, though, and because cyan was formerly known as "cyan blue," we are putting it here on the blue page.
Our two grandaughters, Arianna and Kiley, found this very nice medium cyan or "turquoise" sea glass on La Selva beach near Santa Cruz, California. Although the beach is very sandy where they live, there are bluffs all along the beach that erode a little every year and so adding whatever glass shards may have been discarded on the tops of the bluffs in past years.
So, although the kids are recycling the old "trash" that they pick up on the shore, the beach is also being "fed" fresh shards that should become true collectible beach glass in future years, especially if the sea level rises a few inches over time.
Blue shards of beach glass comes in many hues and intensities, some of which are more familiar in beach glass (from old glass) than others.
The piece shown above is a remarkably-refreshing cyan or "cyan blue" color.
