Jet-black stone - NYT Crossword Clue

Introduction

Today's clue, "Jet-black stone," is a classic example of a straightforward definition clue often found in crossword puzzles. It's a test of direct vocabulary and general knowledge, and for many solvers, the answer will come to mind almost instantly. Let's dig into why this clue works so well and how to approach it if you get stuck.

Clue Analysis

The clue is composed of two key parts:

• "Jet-black": This is a very specific and intense descriptor for the color black. It's named after the mineraloid jet, which is itself a black gemstone. The clue uses this adjective to point you toward a famously dark stone.
• "stone": This tells us we're looking for a mineral, rock, or gemstone.

Putting them together, the puzzle is asking for the name of a well-known stone that is characteristically jet-black. The answer is a four-letter word, a common length for this particular entry in crosswords.

Thinking Approaches

For a clue this direct, there are a few ways your brain might work:

1. Instant Recall: This is one of those clues where the association is so strong that the answer, ONYX, might pop into your head immediately. This is common for high-frequency crossword answers.

2. Mental Rolodex: If it's not immediate, you might start listing black stones you know. Your list could include: jet, obsidian, tourmaline, or onyx. From there, you'd check which one fits the letter count provided by the grid.

3. Crossings are Key: If you're drawing a blank, don't panic! This is what the crossing clues are for. Even one or two letters can unlock the answer. For example, if you get the 'X' from a down clue, there are very few four-letter words for a black stone that end in 'X'. This process of elimination makes the answer clear.

Background Context

Onyx is a variety of layered chalcedony, which is a form of silica mineral. While it is most famous for its uniform black color, onyx naturally occurs in bands of various colors. When the bands are reddish-brown and white, it's known as sardonyx.

Historically, onyx has been used for millennia in jewelry, especially for carving intaglios and cameos, where the contrasting layers can be used to create a striking visual effect. Its deep, consistent black color has made it a symbol of elegance and sobriety.
