Tanzanite and sapphire are two blue beauties that often get compared—but when it comes to price, things aren’t as straightforward as you might think. They both look luxurious, but which one actually costs more?
The Basics
Sapphires are a type of corundum and come in a range of colors, but the most prized are deep, velvety blues—especially the kind from Kashmir, Burma, or Sri Lanka. Tanzanite, on the other hand, is a type of zoisite that’s only found in one place on Earth: Tanzania, near Mount Kilimanjaro. Its signature color is a rich blue-violet that shifts slightly depending on the light.
So... Which Costs More?
In general, sapphires are more expensive than tanzanites, especially at the high end. Fine-quality sapphires can run into tens of thousands per carat, depending on origin, clarity, and saturation. Tanzanite is definitely valuable—especially in larger sizes—but it usually comes at a more accessible price point than sapphire.
But Here’s the Twist
Tanzanite is actually rarer than sapphire. Like, a lot rarer. It’s a single-source stone, and that mine in Tanzania? It’s running out. So while sapphire may be more expensive right now, tanzanite has long-term investment potential if scarcity keeps increasing.
Other Factors to Consider
Sapphire is tougher, scoring a 9 on the Mohs scale, making it perfect for everyday wear like engagement rings. Tanzanite is softer (around 6 to 7), so it’s better for earrings, pendants, or occasional rings. That durability also plays into the price—sapphire is harder to damage, so it's often seen as more “practical” for luxury buyers.
The Verdict
If you're after prestige and tradition, sapphire’s your go-to. If you’re into rarity, color play, and something a bit under the radar, tanzanite is worth a serious look. Price-wise, sapphire usually wins—but don’t sleep on tanzanite's future value.
