Learn the most important factors in choosing a gemstone that will wear well, look right, and hold its meaning.
Precious vs. Semi-Precious Gemstones
If you've spent any time researching gemstone jewelry, you've likely encountered the distinction between precious and semi-precious stones.
The classification dates back to ancient Greece and was formalized in the nineteenth century, when diamonds, rubies, sapphires, and emeralds were designated as the "precious four."
Everything else was grouped as semi-precious by default:
- Alexandrite
- Tanzanite
- Aquamarine
- Morganite
- Tourmaline
- Opal
- Garnet
The problem is that the label was never really about objective value.
- A fine alexandrite is rarer than most rubies.
- A top-grade Paraíba tourmaline commands prices that rival sapphires.
- A Colombian emerald with significant inclusions may be worth far less than a clean, vivid aquamarine.
The categories don't account for any of that.
3 Ways to Determine Real Gemstone Value
What actually determines a gemstone's value and its suitability for a particular piece comes down to three things:
- Rarity in its finest form
- Durability for the way it will be worn
- The meaning it holds for the person wearing it
The Mohs hardness scale offers a practical starting point for durability. A gemstone rated below 7 requires more care and may not be the right choice for a ring worn daily. The Precious Four gemstones all rank above a 7 and can be worn daily without fear of surface scratches.
Rarity is more nuanced, varying by species, origin, color saturation, and treatment history.
And meaning to the individual, of course, can't be graded at all.
Don't let these categories narrow your options before you've had a chance to explore them. Some of the most extraordinary jewelry we've made at Neeter House has been built around stones that don't appear on anyone's "precious" list.
The Precious Four Gemstones
For centuries, four gemstones have stood apart from the rest by rarity and an ability to hold meaning across generations. Understanding what makes each one exceptional is the first step toward choosing a gemstone with confidence.
1. Diamonds
No stone carries more cultural weight than a diamond, and for good reason.
Diamonds are the hardest natural material on Earth (level 10 on the Mohs hardness scale), which makes them both practical and iconic. Their brilliance comes from how they bend and reflect light, a quality that varies significantly by cut.
What separates a forgettable diamond from an extraordinary one is the way it looks in natural light, on your hand, in person.

2. Rubies
A fine ruby is one of the rarest gemstones in the world. The most prized stones are deep, vivid red, known as pigeon's blood, historically associated with Burma's Mogok Valley.
Color is everything with rubies. A slight shift toward pink or brown can significantly change the stone's value. When the color is right, there's nothing quite like it.
Best for: bold statement pieces, anniversary jewelry
3. Sapphires
Most people think blue, but sapphires come in nearly every color — pink, yellow, green, and the rare orange-pink padparadscha. The finest blue sapphires from Kashmir and Ceylon set the benchmark for depth and velvety saturation.
Sapphires are one of the most durable choices for everyday wear, which is part of why they've become an alternative to diamonds in engagement rings.
Best for: unique engagement rings, understated luxury, alternative to diamonds
4. Emeralds
Emeralds are measured by a different standard than most gemstones. Inclusions, which would be considered flaws in a diamond, are expected in emeralds and are even given their own name: jardin, French for garden.
What matters is the saturated, slightly bluish green color that the finest Colombian and Zambian stones achieve in a way nothing else does.
Emeralds require more care than other precious stones, but for those drawn to their depth and history, that's a price they’re willing to pay.
Best for: vintage-inspired pieces, bold color lovers
How to Choose the Right Gemstone for Your Piece
Choosing a gemstone isn’t as simple as picking a favorite color. The right stone for a piece of jewelry depends on how it will be worn, what it needs to withstand, and what you want it to say.
1. Start with durability.
A gemstone's hardness determines how well it withstands daily wear, friction, and the occasional knock against a hard surface.
The Mohs scale runs from 1 to 10, and for anything worn regularly, a stone rated 7 or above is a practical baseline. Diamonds, sapphires, and rubies sit at the top of that range.
This isn't a reason to avoid softer stones. You just have to be thoughtful about how they're set and how often the gemstone jewelry will be worn.
2. Consider the metal.
Think about the relationship between a stone and its setting.
Warm stones (morganite, yellow sapphire, certain garnets) tend to deepen and enrich against yellow or rose gold. Cool-toned stones (aquamarine, blue sapphire, and white diamonds) often read crisper and more vivid in white gold or platinum.
There are no fixed rules here, but it's worth seeing the combination in person before committing.
3. Think about color in context.
Color looks different on the screen than it does in hand, and different in hand than it does against your skin.
Warm skin tones often pair beautifully with stones in the yellow, orange, and warm red family — citrine, padparadscha sapphire, imperial topaz. Cooler skin tones tend to complement blues, greens, and clear whites.
That said, personal resonance matters more than any formula. If a color moves you, that's worth paying attention to.
4. Let meaning inform the decision.
Birthstones, anniversary stones, and stones associated with a particular place or memory carry weight that no grading report can quantify.
Some clients come in knowing exactly which stone they want before they've considered anything else. A gemstone chosen for what it represents tends to remain in a family.
5. See it in person before you decide.
This is the one recommendation that applies across every category, every budget, and every type of piece. Color saturation, brilliance, and the way a stone interacts with light are nearly impossible to evaluate accurately on a screen.
What looks pale in a photograph may be luminous in natural light. What looks vivid in a product image may look different against your hand.
