If you're planning to buy or sell tourmaline, one of the first questions you’ll ask is:

What is the tourmaline price per carat?

The answer depends on color, clarity, origin, and rarity. In this guide, we’ll break everything down in simple terms so you can understand how pricing works and avoid overpaying.

What Is Tourmaline?

Tourmaline is one of the most colorful gemstones in the world. It comes in almost every color — green, pink, blue, red, and even multicolor (watermelon tourmaline).

It is also the birthstone for October, along with Opal.

Because there are many varieties, tourmaline prices vary widely per carat.

Why Tourmaline Prices Vary So Much

Let’s understand the factors that affect tourmaline price per carat.

---

1. Color (Most Important Factor)

Color is the biggest price driver.

• Neon blue Paraiba = extremely expensive

• Deep red Rubellite = high value

• Pure vivid green = strong demand

• Pale or brownish tones = lower price

For example, neon blue Paraiba tourmaline from Brazil is among the most expensive gemstones in the world.

2. Clarity

Tourmaline usually contains inclusions.

• Eye-clean stones = higher price

• Visible cracks/inclusions = lower price

Some varieties like rubellite often have inclusions, but if they are clean, prices rise significantly.

---

3. Origin

Certain origins increase value:

• Brazil – Famous for Paraiba

• Mozambique – High-quality Paraiba & Rubellite

• Afghanistan – Fine green and pink tourmaline

Origin matters especially for collectors and high-end buyers.

4. Carat Weight

Larger stones cost more per carat.

Example:

• 1 carat green tourmaline = $150 per carat

• 5 carat high-quality stone = $300+ per carat

Big, clean stones are rare — and rarity increases price.

Most Expensive Tourmaline: Paraiba

Paraiba tourmaline is the rarest and most expensive type.

Why?

• Electric neon glow

• Copper-bearing composition

• Extremely limited supply

High-quality Paraiba tourmaline can reach $20,000+ per carat.

Is Tourmaline a Good Investment?

Yes — especially rare varieties like:

• Paraiba

• Fine Rubellite

• Indicolite (deep blue)

However, investment depends on:

• Natural & untreated stone

• Proper certification

• High-quality color

For commercial jewelry buyers, green and pink tourmalines offer good value at affordable prices.
