Gemstone Jewelry Buying Guide
Sapphires, rubies, emeralds and more — how to judge color, durability and price before you buy gemstone jewelry.
Start with hardness
The Mohs scale decides where a stone can be worn. Diamonds (10), sapphires and rubies (9) suit daily rings. Emerald (7.5-8) and amethyst (7) are better for earrings and pendants. Shop gemstone pieces.
Popular gemstones compared
| Stone | Mohs | Best wear | Care note |
|---|---|---|---|
| Sapphire | 9 | Every day | Very tough |
| Ruby | 9 | Every day | Avoid heat |
| Emerald | 7.5 | Occasional | No ultrasonic |
| Amethyst | 7 | Earrings | Sunlight fades |
Check color and treatment
Look for even color and ask if the stone is heat-treated or oiled, which is normal and lowers price. Always ask for clarity of origin and treatment disclosure. Ask about our gemstone pieces.

Which gemstone is toughest for daily wear?
Sapphire and ruby, both at 9 on the Mohs scale. Diamond is the only harder stone.
Are treated gemstones worth less?
Heat treatment is standard and accepted. Disclosure matters more than the treatment itself.
Can I clean gemstone jewelry in an ultrasonic cleaner?
Only for hard stones like sapphire and ruby. Emeralds and opals should never go in ultrasonic.
