When it comes to choosing an engagement ring, diamonds have long been the traditional choice. However, as tastes evolve and people become more conscious about price, ethics, and uniqueness, diamond alternatives are rising in popularity. Whether you're looking to save money, make an ethical choice, or stand out with a distinctive gem, there are several stunning options available.

Here are the 7 best diamond alternatives to consider for your engagement ring.

1. Moissanite

Why choose it: Brilliant, durable, and affordable
Mohs Hardness: 9.25
Price: ~10–20% of a diamond’s cost

Moissanite is arguably the most popular diamond alternative, and for good reason. First discovered in a meteor crater, this gemstone has a fiery brilliance that even outshines a diamond. Lab-created Moissanite is now widely available, offering a nearly colorless look with exceptional sparkle.

Not only is it stunning and durable (suitable for daily wear), but it's also an eco-friendly and conflict-free option. Moissanite’s affordability allows couples to choose larger stones or more elaborate designs without exceeding their budget.

Best for: Those who want maximum sparkle at a fraction of the price.

2. White Sapphire

Why choose it: Natural, affordable, and timeless
Mohs Hardness: 9
Price: ~10–30% of a diamond’s cost

White sapphires are another fantastic diamond alternative. They offer a classic, clear appearance and are naturally occurring. While they don't sparkle as much as diamonds or Moissanite, they still hold a soft, elegant glow.

White sapphires are a great choice for traditionalists who prefer a natural gemstone and are looking for a subtle yet refined appearance. They’re also durable enough for everyday wear.

Best for: Lovers of natural stones with timeless appeal.

3. Lab-Grown Diamonds

Why choose it: Real diamonds, ethically made
Mohs Hardness: 10
Price: ~30–50% cheaper than mined diamonds

Lab-grown diamonds are real diamonds—physically, chemically, and optically identical to mined ones. The difference? They’re created in a controlled environment, meaning they have zero ethical concerns, no environmental degradation, and a much lower cost.

These diamonds are increasingly popular among eco-conscious and socially responsible couples. Since they’re indistinguishable from mined diamonds, lab-grown options are ideal if you want all the sparkle and status of a real diamond without the baggage.

Best for: Traditional look with modern values.

4. Morganite

Why choose it: Romantic pink hue and affordable pricing
Mohs Hardness: 7.5–8
Price: ~10–15% of a diamond’s cost

Morganite has gained popularity for its soft pink to peach tones, which symbolize compassion and love. It's part of the beryl family (which also includes emerald and aquamarine), and its blush color is a refreshing twist on the traditional engagement ring.

While not as hard as diamonds or Moissanite, Morganite is still durable enough for most wearers, especially with proper care. Its affordable price and romantic vibe make it a go-to for couples who want something feminine and unique.

Best for: Romantic souls who love a touch of color.

5. Aquamarine

Why choose it: Cool, oceanic tones and natural clarity
Mohs Hardness: 7.5–8
Price: ~5–15% of a diamond’s cost

Aquamarine, with its light blue hue and serene glow, is a beautiful and refreshing diamond alternative. As a cousin to emerald and Morganite, it's also part of the beryl family and is valued for its clarity and calming color.

Though slightly softer than a diamond, Aquamarine is suitable for an engagement ring with the right setting and regular care. It's an especially great option for those who want a non-traditional but elegant look.

Best for: Beach lovers and fans of soft, unique tones.

6. Cubic Zirconia (CZ)

Why choose it: Very affordable and diamond-like in appearance
Mohs Hardness: 8–8.5
Price: ~1–2% of a diamond’s cost

Cubic Zirconia is one of the oldest and most accessible diamond alternatives. It’s man-made, inexpensive, and closely resembles a diamond at a glance. While it lacks the fire and durability of diamonds or Moissanite, it still shines beautifully.

CZ is best suited for budget-conscious couples or temporary rings. Over time, it may show signs of wear or dulling, but at such a low cost, replacing it is easy.

Best for: Budget-minded buyers or temporary/placeholder rings.

7. Spinel

Why choose it: Naturally brilliant and available in many colors
Mohs Hardness: 8
Price: ~5–20% of a diamond’s cost

Often mistaken for ruby or sapphire in history, Spinel is a naturally occurring gemstone known for its high brilliance and wide color range—from colorless to red, blue, pink, and violet. White Spinel is the variant most commonly used as a diamond alternative.

Spinel is durable, eye-catching, and lesser-known, making it a great pick for couples who want a gemstone that feels special and unique without being too unconventional.

Best for: Unique personalities and lovers of under-the-radar gemstones.

Factors to Consider When Choosing a Diamond Alternative

Before selecting your alternative gemstone, keep the following in mind:

  1. Hardness and Durability: Engagement rings are worn daily, so the gem should be resistant to scratches and chips. Choose stones with a Mohs rating of 8 or higher.

  2. Brilliance and Fire: If sparkle is important to you, opt for Moissanite or lab-grown diamonds. If you're okay with a more subtle look, white sapphire or aquamarine may be perfect.

  3. Color: Many alternatives offer beautiful colors (e.g., Morganite, Aquamarine, Spinel). Decide whether you want a colorless gem or something more personal.

  4. Ethics: Lab-grown options or non-conflict natural stones provide peace of mind for socially conscious buyers.

  5. Budget: Some stones can help you save thousands of dollars. Prioritize what matters most—appearance, durability, origin, or symbolism.
