Choosing alternative engagement stones is a thoughtful way to express a love story that’s anything but expected. These gems offer color, character and symbolism that help a ring reflect your unique story rather than tradition alone.
These stones also appear throughout many engagement ring alternatives, giving modern couples more freedom to choose a ring that reflects their style. Below, we highlight 10 beautiful choices worth considering for your gemstone engagement ring in 2026.
1. Blue Sapphire

Blue sapphires offer brilliant depth of color and an enduring association with sophistication and loyalty. Sapphires are also a 9 on the Mohs Scale of Hardness, meaning they’re exceptionally strong and ideal for everyday wear.
Even though you can find sapphires in many colors, the vivid blue is one of the most recognizable gemstone hues. It brings both contrast and elegance to engagement rings, especially when paired with diamond accents that enhance its natural radiance. Whether you’re drawn to vintage designs or classic solitaires, sapphires are one of the best stones for engagement rings.
2. Emerald

Emeralds rank between 7.5 and 8 on the Mohs Scale of Hardness, offering dependable durability with attentive care. Its popularity comes from its intense green color, long linked to romance, renewal and timeless elegance.
No two emeralds look exactly alike. Their internal characteristics give them individuality, making them appealing if you want a stone with natural personality. Emeralds shine most in simple designs that let their striking color take center stage, though halo and side-stone settings also enhance their vibrant glow.
3. Ruby

Ruby makes a confident statement on the hand. Whether paired with diamonds or set atop a simple band, its vivid hue adds drama in a way that feels timeless. It’s cherished for its bold red color, which symbolizes passion and protection.
Ruby ranks 9 on the Mohs Scale of Hardness, giving it long-term resilience and exceptional wearability. Because of its durability, ruby works beautifully for people with active lifestyles who still want a gemstone with personality.
4. Morganite

Morganite is beloved for its soft peachy-pink color. This stone creates a warm, romantic glow. Its pastel color creates a dreamy effect without being overly bold.
This stone pairs effortlessly with rose gold, and the combination has become a favorite among people wanting a ring with understated elegance. Additionally, Morganite ranks between 7.5 and 8 on the Mohs Scale of Hardness, making it suitable for engagement rings with gentle care.
5. Tanzanite

Tanzanite is one of the most distinctive gemstones on the market because it comes from a single source: a small area in the Merelani Hills of northern Tanzania, near the foothills of Mount Kilimanjaro. Its rarity adds to its appeal, making it an exciting choice for anyone wanting a ring with a sense of exclusivity and depth.
It’s also popular for its unusual and gorgeous shifting color that moves between rich blue and violet. Keep in mind that tanzanite ranks 6 to 7 on the Mohs Scale of Hardness, which means it benefits from mindful everyday wear.
6. Topaz

Topaz ranks an 8 on the Mohs Scale of Hardness, giving it durability and versatility across a range of ring styles. It’s admired for its broad color spectrum, available in yellows, pinks, reds, purples, greens and browns. Yet, the bright blues are the ones that continue to trend.
From London blue to sky blue, topaz offers striking shades that feel modern and vibrant. If you’re browsing unique stones for engagement rings, this gemstone opens the door to colorful and expressive designs.
7. Pink Sapphire

Like blue sapphire, pink sapphire ranks a 9 on the Mohs Scale of Hardness, making it an excellent choice for vivid style and practical wearability. Its romantic, colorful presence and its ability to stand up to daily life draw jewelry lovers.
Pink sapphire ranges from barely-there blush to bright magenta. It offers the same durability of a traditional blue sapphire with a look that feels lighthearted and expressive. Couples seeking non-traditional engagement ring stones often gravitate to this uplifting shade.
8. Aquamarine

Many couples choose aquamarine because it provides a soft color without overwhelming the design. This makes it a beloved option among today’s diamond alternatives, especially for those who want something light and airy.
Aquamarine ranks 7.5 to 8 on the Mohs Scale of Hardness, making it a dependable choice with proper care. Its pale blue tone offers a calm, icy look that serves as a subtle alternative to diamonds.
9. Amethyst

Amethyst ranks a 7 on the Mohs Scale of Hardness, offering moderate durability for engagement rings worn with care. It’s popular for its rich purple color, which makes any ring feel expressive and distinctive.
From deep plum to soft lavender, amethyst provides a wide range of purple hues to explore. Its versatility makes it appealing for people who want a gemstone that stands out without feeling overly bold. For a regal look, consider a setting in your perfect shade of gold.
10. Garnet

Garnets are popular for their warmer and moodier tones—from deep red to vivid orange—as well as their affordability when compared to rubies. They rank 6.5 to 7.5 on the Mohs Scale of Hardness, offering moderate durability with a wide range of bold, deep colors.
