Teal Sapphire Price Guide — What They Cost and What Drives the Range

Teal sapphire — the blue-green variety of corundum that has become one of the most commercially sought-after sapphire colors over the past decade — occupies a distinctive position in the sapphire market. It is significantly less expensive than fine blue sapphire of equivalent quality, frequently available unheated without the premium that unheated blue commands, and produces some of the most visually striking engagement ring stones available. For buyers who want vivid, naturally unheated sapphire color at meaningful size without the per-carat cost of fine blue, teal is the most compelling value in the sapphire market.

This guide covers what teal sapphires actually cost in 2026, what drives the price variation within the teal category, how color ratio and saturation affect value, and what realistic budgets will get you across quality tiers and carat weights.

What Teal Sapphire Is — and Why Most Is Unheated

Teal sapphire is a blue-green corundum whose color is produced by a combination of iron (driving the blue component) and trace elements that shift the hue toward green. The specific ratio of blue to green varies significantly across the teal range — from strongly blue-leaning teal (often called "ocean teal" or "deep teal") to more balanced blue-green ("true teal") to more strongly green-leaning ("green-teal" or "forest teal").

Most teal sapphire on the market is naturally unheated — not because treatment is impossible, but because the iron-driven color mechanism of teal sapphire is generally stable at high temperatures and heat treatment produces minimal improvement. This means the unheated status of most teal sapphire does not carry the same scarcity premium it does for blue sapphire. An unheated teal is the norm, not the exception — which is why teal prices do not include the 2×–5× unheated premium that fine unheated blue commands. This is one of the primary reasons teal offers such strong value per carat relative to blue.

Ceylon (Sri Lanka) is the primary source of fine teal sapphire, with material also coming from Australia (typically darker, stronger green), Madagascar (variable), and Tanzania. Ceylon teal typically shows the most balanced, vivid blue-green color and commands the highest prices within the teal category.

What Drives Teal Sapphire Prices

Color ratio and balance

The ratio of blue to green in a teal sapphire is its single most important quality factor from a pricing perspective. The most commercially valued teal ratio is approximately 50% blue, 50% green — or what the market describes as "true teal" — a vivid, balanced blue-green with neither component dominating. Stones strongly skewed toward blue (more than 70% blue) price closer to blue sapphire in character; stones strongly skewed toward green (more than 60% green) can trend toward lower demand in some markets. The balanced ratio is the most universally sought and commands the premium within the teal category.

Saturation and tone

As with all sapphire colors, vivid saturation with medium to medium-dark tone commands the highest prices. Very dark teal that appears nearly navy or forest green face-up, or very light teal that looks washed out, trade at significant discounts to vivid, well-saturated material. The best teal sapphires display their blue-green character with intensity across lighting conditions — including under warm indoor light where some teal stones shift color significantly.

Color shift behavior

Teal sapphires can show color shift behavior — appearing more blue under cool daylight and shifting toward green under warm incandescent light. This is a characteristic feature of teal, not a defect, and the degree of shift affects how the stone is valued. Stones with dramatic shifts may be marketed as a feature; buyers who want a consistent color across lighting should assess the stone under multiple light sources before purchasing.

Cut and face-up size

As with all sapphire, well-cut teal stones with minimal windowing and good depth percentage command meaningful premiums over weight-optimized native cuts. A teal sapphire cut for face-up performance will display its blue-green color evenly and vividly; a window-heavy stone will show a pale, transparent zone across the face. See our cut quality guide.

Teal Sapphire Price by Quality Tier (2026)

Good and Fine quality figures reflect current listed prices in our collection as of August 2026 — our stock currently runs 1.08ct to 2.12ct, all naturally unheated. *Commercial and Very fine/exceptional tiers are broader market guidance; we don't currently stock teal at either end of that spectrum. Figures are not fixed quotes and will move with inventory.

Example from our collection: a 1.08 ct AGCL-certified unheated teal sapphire from Madagascar, round cut — $788 ($730/ct). View this stone. A 1.75 ct GIA-certified unheated teal, cushion cut — $1,575 ($900/ct) (view). Our finest currently in stock: a 2.08 ct GIA-certified unheated teal, round cut — $2,912 ($1,400/ct) (view).

These prices represent direct-source pricing. Traditional retail through high-street jewelers typically runs 40–80% higher for equivalent material. The teal category has also seen meaningful price appreciation over the past five years as demand has grown — buyers who purchased fine teal in 2019–2021 at lower prices have seen significant appreciation in their stones' market value.

Teal Sapphire Price by Carat Weight

The 1.00ct–2.00ct rows reflect current listed prices in our collection. *0.50ct and 3.00ct+ rows are broader market guidance — we don't currently stock teal at either size; our range runs 1.08ct to 2.12ct.

Within the sizes we actually stock (roughly 1ct to 2.12ct), teal price escalation with carat weight has been modest — per-carat pricing clusters in the $700–$1,600 range across that whole window rather than climbing steeply the way fine blue or padparadscha does. That is itself part of teal's value proposition: a buyer can move up in size within our current stock without paying a steep per-carat premium for the privilege. Above 2.12ct, or below 1ct, expect wider variation since we're not able to verify those sizes against current listings.

Teal Sapphire vs. Blue Sapphire — Price Comparison

The price differential between teal and blue sapphire of equivalent quality is significant and consistent:

Teal figures reflect current listed prices in our collection. Blue (unheated, GIA) figures are based on our GIA-certified unheated blue stock, which currently starts at 2 carats — see our 1-carat sapphire pricing guide for the full breakdown of that extrapolation.

For buyers who appreciate vivid, naturally unheated Ceylon color and want the most stone at a given budget, teal is the strongest value proposition in the sapphire market. The price premium for blue exists because of historical prestige and demand — not because blue is visually superior in all settings. In rose gold or yellow gold, a fine vivid teal can outperform blue in terms of the finished ring's overall visual impact.

Does Teal Sapphire Need a GIA Report?

Unlike padparadscha (where GIA certification is mandatory for the premium) or unheated blue (where GIA confirmation is strongly recommended for stones above $1,000/ct), teal sapphire's value equation is somewhat different. Since most teal is naturally unheated, the treatment status question is less fraught — but confirmation from a reputable source is still valuable for any stone above $1,000 total value.

At Crescent Gems, all teal sapphires include our full treatment disclosure and most include independent laboratory documentation. For stones above $2,000 total value, GIA or equivalent documentation is our standard recommendation. See our GIA report guide for the full framework on certification decisions.

What Teal Sapphire Looks Like in a Ring

Teal sapphire is one of the most versatile colored stones for engagement ring design because of how differently it reads across metal colors:

• Rose gold: The most popular combination — warm pink-gold against the blue-green teal creates a sophisticated complementary contrast that photographs beautifully and wears elegantly. This is the dominant aesthetic for teal engagement rings in the current market.
• Yellow gold: Warms the teal toward its green component, creating an earthy, vintage character — a teal in yellow gold looks rich and jewel-like in a way that distinctly differs from the modern-contemporary rose gold aesthetic.
• Platinum / white gold: Emphasizes the blue component and creates the coolest, most contemporary look — clean, vivid, and striking.

Frequently Asked Questions

How much does a teal sapphire cost?

A 1-carat teal sapphire in our current collection runs $700–$1,400/ct for good-to-fine, naturally unheated, vivid blue-green Ceylon or Madagascar quality — for example, a 1.08 ct stone at $788 ($730/ct) up to GIA-certified stones around $1,400/ct. Commercial-grade material can be found for less in the broader market, though we don't currently stock it. At 2 carats, our finest currently in stock runs about $1,400/ct — notably, we haven't seen a strong per-carat premium for size within the 1–2.12ct range we carry. These prices reflect direct-source pricing; traditional retail typically runs 40–80% higher.

Are teal sapphires always unheated?

Most commercially available teal sapphires are naturally unheated — the iron-driven color mechanism of teal is generally stable at the temperatures used in heat treatment, making treatment less effective and therefore less commercially practiced. This is one reason teal does not carry the large unheated premium that applies to fine blue sapphire. Always verify treatment status with your seller; at Crescent Gems all teal sapphires include full treatment disclosure.

Is teal sapphire a good investment?

Fine teal sapphire has seen meaningful price appreciation over the past five to seven years as the market has discovered the color category. Whether this appreciation continues depends on demand trends that cannot be predicted. As a pure investment vehicle, gemstones are illiquid assets with no guaranteed market. As a meaningful stone with genuine rarity, beauty, and direct-source provenance, fine teal sapphire has strong intrinsic value. See our collector and investment gemstone guide.

What is the best teal sapphire color?

The most commercially valued teal color is vivid, balanced blue-green — approximately equal parts blue and green, in medium to medium-dark tone with strong saturation, minimal grey modifier. Stones that skew strongly toward blue or strongly toward green are less universally sought, though personal preference varies. See our teal sapphire guide for the full color framework.
