It’s diamond season. Almost 40 percent of American engagements happen between Thanksgiving and Valentine’s Day, with Christmas the most popular day to pop the question – and hand over a sparkly piece of ice. Jewelry stores do at least double their usual monthly sales in December.
Ask most people what the hardest material on Earth is and they will probably answer “diamond”. Its name comes from the Greek word ἀδάμας (adámas) meaning “unbreakable” or “invincible” and is from where we get the word “adamant”. Diamond’s hardness gives it incredible cutting abilities that – along with its beauty – have kept it in high demand for thousands of years.
As giant icebergs bob across the open seas they leave behind a trail of nutrient-rich meltwater, sparking new life in the world’s remotest and least hospitable oceans. This in turn means more carbon is taken from the atmosphere and stored below the waves. Massive icebergs may be a symptom of climate change – but they can also help keep it in check.
