What it evokes
In tradition, diamond is the stone of firmness: it is credited with a resistance nothing can wear down, like its hardness, and crystal books link it to confidence and faithful love.
This reading is old. Its Greek name, adamas, means “untamable,” and Pliny says it makes iron bounce off the anvil. In 1913, Kunz sums up the virtues attributed to diamond: almost all come from its hardness and transparency, and it was seen as a pledge of victory, strength, and courage.
It serves as a marker: a sparkle you look at to remember to stay steady.
The traditions
- Rome, 1st century
Pliny places diamond at the highest price of all human things, long known only to kings. He reports that the anvil splits under the test, that this untamable strength earned it its Greek name, and that some called it ananchite, “nightmare-free,” because it was said to drive away idle terrors. He also notes that, according to belief, only warm goat’s blood can overcome the stone.
Pliny the Elder, Natural History, XXXVII, 15 (Littré translation) - Middle Ages
Kunz reports that Marbode saw in it a stone able to drive away the specters of the night, to be set in gold and worn on the left arm, and that another author, Rueus, called it a “stone of reconciliation” between spouses. Cardano, on the contrary, judged that it makes its wearer fearless but unhappy, and that it is better to fear it.
Gutenberg 57978, Kunz 1913, chapter “Diamond” - 1912 list
April goes to diamond in the American list of 1912. Kunz, who comments on it, doubts that the ancients knew diamond and suggests using it instead as a border around the month’s gem, as an ornament.

Nuances and sources
Each modern book links it to its own signs and chakras, with no agreement among them. Kunz doubted that the ancients knew diamond: an Orphic poem that speaks of adamas refers, in his view, to white sapphire or quartz. Trade names and imitations are numerous, and synthetic diamond is real diamond.

Diamond: your questions
How can you tell a diamond from a cubic zirconia or a moissanite?
By eye, the difference is slight. The site lists these imitations: cubic zirconia, synthetic moissanite, glass, and synthetic diamond, which is carbon just like the natural kind. Only a gemological lab, or at the least a tester at a jeweler’s, settles it with certainty. Be wary of a very low price, and ask for the words natural, synthetic, or imitation on the invoice.
Is a diamond indestructible?
No. Its hardness protects it from scratches, but a sharp, well-placed blow can chip it, and the site also advises against strong, prolonged heat. Kunz points out that in the 14th century it was not known that at very high temperatures it can burn up. Store it apart from other jewelry: it scratches many things, and a knock against another diamond can damage it.
Why is diamond the April birthstone?
Because the jewelers gathered in Kansas City in 1912 chose it for that month. According to Kunz, the ancients did not give it, since they did not know it: so it is a recent commercial choice rather than an ancient tradition. If its color does not speak to you, nothing obliges you to follow it.
