April Birthstone Guide: Diamond, White Sapphire, and White Topaz Compared
Three clear, brilliant stones for one birthday. Here's how to choose between them by hardness, budget, and how you'll actually wear it.
If you're shopping for April birthstone jewelry, you have more options than you might think. Diamond is the official April birthstone, but white sapphire and white topaz are real, natural alternatives that share the same clear brilliance at very different price points. This guide covers what each stone is, who it's right for, and how to choose between them.
Diamond (Mohs 10) is April's primary birthstone and the most durable choice for rings and heirloom pieces. White sapphire (Mohs 9) is a real gemstone — corundum, like blue sapphire and ruby — and the closest natural alternative to diamond. White topaz (Mohs 8) is the most affordable, starting at $20, and works beautifully for everyday necklaces, earrings, and layering. All three are real, natural gemstones.
April's three birthstones at a glance
Diamond: The classic April birthstone
Diamond is the official April birthstone, recognized by both the American Gem Society and the Gemological Institute of America. It rates a perfect 10 on the Mohs hardness scale, making it the hardest natural substance on Earth and the most durable gemstone for jewelry that sees daily wear.
Diamond is pure crystallized carbon, formed under extreme heat and pressure deep in the Earth's mantle. Lab-grown diamonds share identical chemical, physical, and optical properties with mined diamonds and are an increasingly popular option for buyers who want the same brilliance at a lower price point. Both natural and lab-grown diamonds are certified by the GIA and IGI using the same grading criteria. At Erin Gallagher Jewelry, we hand-select both to G+ color and VS-F+ clarity.
Who diamond is right for
- Anyone who wants the most durable stone available for everyday wear, including rings
- Buyers who want heirloom-quality fine jewelry in 14K gold
- Milestone gifts: engagements, anniversaries, significant birthdays
- Anyone drawn to the symbolism of the world's hardest natural material
Prices at Erin Gallagher Jewelry start at $135 for diamond pieces in sterling silver, and from $210 for 14K gold. Browse our diamond jewelry, or read our full lab-grown vs natural diamonds guide.
White Sapphire: The natural diamond alternative
White sapphire is the colorless variety of corundum, the same mineral family as ruby and blue sapphire. It rates 9 on the Mohs hardness scale, making it the second hardest natural gemstone after diamond. That hardness sets it apart from other diamond alternatives: white sapphire is genuinely tough enough for daily wear in any jewelry type, including rings.
White sapphire is a natural gemstone, not a synthetic or lab-created simulant. It should not be confused with cubic zirconia or moissanite, which are different materials entirely. White sapphire has a distinct brilliance — slightly softer in sparkle than diamond, but with its own warm, natural glow. It's found primarily in Sri Lanka, Madagascar, and Myanmar.
Who white sapphire is right for
- Buyers who want a natural stone closest to diamond in hardness and appearance
- Anyone who prefers a genuine gemstone at a lower price than diamond
- Engagements, anniversaries, and meaningful gifts where durability matters
- Buyers who value the stone's connection to wisdom and clarity
Prices at Erin Gallagher Jewelry start at $225 for white sapphire pieces. Browse our white sapphire collection.
White Topaz: The most accessible April birthstone
White topaz is the colorless, purest form of topaz, a silicate mineral found in Brazil, Sri Lanka, Nigeria, and parts of the United States including Colorado. It rates 8 on the Mohs hardness scale, which is durable enough for necklaces, earrings, and bracelets worn daily with reasonable care. For rings that see heavy daily use, a harder stone is a better choice.
White topaz is a genuine natural gemstone, not a synthetic or lab-created material. Its name comes from the Sanskrit word tapas, meaning fire. It offers the same clear, bright look as diamond and white sapphire at a significantly lower price point, making it the most accessible entry into April birthstone jewelry.
Who white topaz is right for
- Budget-conscious buyers who want real gemstone sparkle without a high price tag
- Layering pieces, everyday necklaces, and earrings where durability demands are lower
- First jewelry gifts, "just because" moments, and stocking stuffers
- Anyone who wants to wear April's birthstone in multiple pieces at once
Prices at Erin Gallagher Jewelry start at $20 for white topaz charms, with necklaces and earrings from $95 and bracelets from $135. Browse our white topaz jewelry.

What the stones mean
All three April birthstones share the same symbolic connection: they're associated with the crown chakra, linked to clarity of thought, awareness, and honest communication. Diamond's name comes from the Greek adamas, meaning unconquerable, and it has symbolized strength and eternal love across cultures for centuries. White sapphire's association with wisdom and integrity dates back to ancient traditions that prized its connection to clear judgment. White topaz takes its name from the Sanskrit word for fire and is considered a stone of awareness and focus.
Hardness and everyday wear: what the numbers mean
Mohs hardness determines how resistant a stone is to being scratched. The scale runs from 1 (talc) to 10 (diamond). Here's what those numbers mean in practice for April birthstones:
- Diamond (Mohs 10). Cannot be scratched by anything except another diamond. The safest choice for rings worn every day.
- White sapphire (Mohs 9). Can only be scratched by diamond. An excellent choice for all jewelry types, including everyday rings.
- White topaz (Mohs 8). Can be scratched by diamond, sapphire, and other Mohs 9+ materials. Well-suited for necklaces, earrings, and bracelets. For rings, choose a protective setting (bezel over prong) and remove before activities that involve impact or abrasion.
One practical note: household dust often contains quartz particles, which rate 7 on the Mohs scale. Over time, white topaz in a ring setting may show light surface scratching from normal daily contact. Diamond and white sapphire won't.

Frequently asked
Is white sapphire a real diamond alternative?
Yes. White sapphire is a real, natural gemstone (the colorless form of corundum) and the second hardest natural stone after diamond. It's not the same as cubic zirconia or moissanite, which are different materials. Of all the natural alternatives, white sapphire is closest to diamond in both hardness and appearance.
What's the difference between white sapphire and white topaz?
Both are natural, clear gemstones, but white sapphire (Mohs 9) is significantly harder than white topaz (Mohs 8), which means it resists scratches better over time. White sapphire is also more expensive. White topaz offers a similar look at a lower price point but isn't ideal for rings that see heavy daily wear.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have identical chemical, physical, and optical properties to mined diamonds. They're certified by the same grading bodies (GIA, IGI) using the same criteria. The only difference is origin — they're grown in a lab in weeks rather than formed over millions of years underground.
Does April have more than one birthstone?
Diamond is April's primary and official birthstone, but white sapphire and white topaz are widely recognized alternatives. Some traditions also include rock crystal or clear quartz. At Erin Gallagher Jewelry, we offer all three primary options.
What zodiac signs fall in April?
April covers Aries (March 21 to April 19) and Taurus (April 20 to May 20). All three April birthstones work for both signs.
Which April birthstone is best for an engagement ring?
Diamond (Mohs 10) is the most durable and traditional choice. White sapphire (Mohs 9) is an excellent natural alternative that costs less and holds up to daily wear. White topaz (Mohs 8) is generally not recommended for engagement rings because it's softer and more prone to scratching with daily use.
