April birthstone: Diamond
Diamond illustration
April’s birthstone is diamond: famous, hard, and carrying more advertising history than almost any other rock on the list.
What diamond is
Diamond is crystalline carbon. On the Mohs scale it tops everyday jewelry materials, which is why it survives decades of wear when well set. Clarity, cut, and color (the usual grading conversation) matter more for price than for the simple fact of “April birthstone.”
How April got diamond
The modern Western list assigns diamond to April. Romantic marketing did the rest. Older traditions sometimes favored other April associations; jeweler lists are the version this site reports.
Birth month vs zodiac gems
Aries and Taurus overlap April. Their gem folklore is separate from the month stone. You can enjoy both without pretending they are the same chart.

Common questions
What is the April birthstone?
Diamond is the primary April stone on the modern Western jewelry calendar.
Are lab-grown diamonds still April birthstones?
Chemically they are still diamond. Birthstone tradition cares about the material name, not where it was grown. Preferences about natural vs lab-grown are personal and ethical, not geological.
Does April only mean colorless diamond?
Colorless stones dominate gift marketing, but fancy colored diamonds exist. Most April birthstone jewelry you see is still clear or near-clear.
