April Birthstone Guide

Diamond, the April birthstone, captivates with its unmatched brilliance and durability.

What Is the Birthstone for April?

Diamond is the official birthstone for April. As nature's hardest substance, diamond stands as a fitting symbol for those born during this month of renewal and growth. Dating back billions of years, diamonds are among the oldest treasures on Earth.

The name "diamond" derives from the Greek word "adamas," meaning "invincible" or "unbreakable," reflecting its exceptional durability. This characteristic makes diamond not just a beautiful gemstone but also a powerful symbol of endurance and strength for April-born individuals.

April Birthstone History & Meaning

Diamonds were first discovered in India around the 4th century BC, and quickly became symbols of power, strength, and invincibility. By the Middle Ages, diamonds were believed to have healing properties, capable of curing ailments and warding off evil. The tradition of giving diamonds as a birthstone for April was solidified in the early 20th century, when the modern birthstone list was established.

For April-born individuals, diamonds symbolize eternal love, strength, and invincibility. The hardness and durability of diamonds make them a perfect symbol of an unbreakable bond, which is why they are often associated with marriage and lifelong commitment. Additionally, diamonds are believed to bring balance, clarity, and abundance to the wearer, attributes often associated with the refreshing clarity of the spring season when April occurs.

April Birthstone Color 

Diamonds are traditionally known for their clear, colorless appearance. Fancy-colored diamonds, which come in hues like blue, pink, yellow, and green, are also highly prized and can be even more valuable than their colorless counterparts. The color is determined by the types of trace impurities and structural irregularities in the crystal when the diamond forms.

The diamond's exceptional optical properties — including its high refractive index and dispersion — give it the remarkable ability to bend and separate light into the colors of the spectrum, creating that distinctive sparkle and fire that makes diamonds so desirable.

April Birthstone Durability

One of the defining characteristics of diamonds is their exceptional durability. Diamonds rank a perfect 10 on the Mohs scale of mineral hardness, making them the hardest known natural material on Earth. This hardness means diamonds are resistant to scratches and abrasions, making them ideal for everyday wear. 

This extraordinary durability is why diamonds have become such a powerful symbol of enduring commitment, particularly in engagement rings. For those born in April, this characteristic reflects an innate strength and resilience that serves them well throughout life's challenges.
