Gemstone rings are more than beautiful accessories—they often symbolize love, commitment, and milestones. Whether you’re choosing a gemstone engagement ring, a gift, or an heirloom piece, it’s essential to understand how well that stone will hold up to everyday wear.
This guide explores the Mohs Hardness Scale, gemstone toughness, and which stones are suitable for daily use. With a detailed infographic and expert insights, this post will help you make confident decisions when shopping for gemstone jewelry.
TL;DR:
- Diamonds, sapphires, and rubies are the best gemstones for daily wear due to their high hardness and toughness.
- Emeralds, topaz, and aquamarine are beautiful but better for occasional use due to their risk of chipping or internal inclusions.
- Soft stones like opal, moonstone, and turquoise are too fragile for daily rings and should be reserved for protected settings.
- Consider hardness and toughness when choosing gemstones for engagement rings or everyday jewelry.
Understanding the Mohs Hardness Scale
The Mohs scale ranks minerals from 1 to 10 based on their resistance to scratching. It’s an essential reference when evaluating gemstones for durability. However, hardness is just one part of the picture. Some stones may rank high on the scale but still chip easily due to internal flaws or cleavage planes.
Here’s what the scale means in context:
- Hardness 9–10: Excellent scratch resistance (diamond, sapphire)
- Hardness 7–8: Moderate resistance; safe with care
- Hardness <7: Prone to scratches and not recommended for daily rings

Gemstone Durability Guide: Mohs Hardness and Daily Wear Suitability
Hardness vs. Toughness: What’s the Difference?
Many buyers confuse hardness with durability. But the full picture includes:
Property | Definition | Example |
Hardness | Resistance to scratching | Diamond (10) |
Toughness | Resistance to breaking or chipping | Jade is tough but soft |
Stability | Resistance to heat, light, chemicals | Opals are unstable under dry conditions |
A diamond, for example, is tough but can still cleave if struck at the wrong angle. Meanwhile, emeralds, despite being reasonably hard (7.5–8), are brittle due to internal fractures called inclusions.
Best Gemstones for Daily Wear
- Diamond (10/10)
- The hardest natural material on Earth
- Excellent scratch resistance and fair toughness
- Timeless and perfect for engagement rings
- Sapphire (9/10)
- Second only to diamonds in hardness
- Available in many colors (including pink and white)
- Durable and classic, great for heirloom rings
- Ruby (9/10)
- A variety of corundum (same family as sapphire)
- Excellent for daily wear but may have inclusions that require careful setting.
- Spinel (8/10)
- Often confused with ruby or sapphire
- Excellent durability, underrated in fine jewelry
Gemstones Better Suited for Occasional Wear
Emerald (7.5–8)
- Iconic green hue, rich history
- Prone to fracturing; often treated with oil to mask inclusions
- Best in protective settings like bezels or pendants
Aquamarine (7.5–8)
- Gorgeous blue tone
- Can be worn often with care
- Avoid direct impacts or extreme temperatures
Topaz (8)
- Beautiful sparkle, comes in many colors
- Has cleavage planes—can chip with a single knock
Soft or Fragile Gemstones: Handle with Care
These gems are visually stunning but not recommended for rings worn daily:
- Amethyst (7) for light wear; best in earrings or pendants
- Citrine (7) Similar to amethyst in durability
- Peridot (6.5–7) Can abrade and chip
- Tanzanite (6–7) Rare and vibrant but brittle
- Zircon (6–7.5) Can chip; often confused with cubic zirconia
- Moonstone, Opal, Turquoise (5-6) Visually striking but too soft and unstable for rings
If you love these stones, choose necklaces, earrings, or cocktail rings to be worn occasionally.
How to Extend the Life of Your Gemstone Jewelry
Even the most durable gemstones benefit from proper care:
- Use protective settings like bezels for softer stones
- Avoid ultrasonic cleaners on porous or treated gems
- Remove rings before exercising, gardening, or using chemicals
- Store separately to avoid scratches from harder gems
FAQ: Gemstone Durability
Can I wear my emerald engagement ring every day?
You can, but it’s risky. Emeralds are brittle and often contain inclusions. Use a protective setting and avoid daily physical activity with the ring on.
Which gemstones are safest for active lifestyles?
Diamond, sapphire, and spinel are the best options. They resist scratches and are tough enough to withstand knocks.
What’s the most fragile gemstone commonly used in rings?
Opal. It’s soft (5.5–6.5), porous, and highly sensitive to dryness, heat, and chemicals.
Is the Mohs scale enough to judge durability?
No—it’s just one piece of the puzzle. Always consider toughness (resistance to breakage) and stability (resistance to light, heat, and chemicals).
Conclusion: Choose Wisely for Forever Jewelry
If you’re selecting a gemstone for an engagement ring or a piece meant for daily wear, prioritize stones that rank high on the Mohs scale and have good toughness. While aesthetics and symbolism are important, understanding gemstone durability helps ensure your jewelry remains stunning and intact for decades.
