How We Calculate Turquoise Value

Cabochon Value = Weight x Base Rate x Mine Premium x Color x Treatment Discount
Jewelry Value = Stone Value + Metal + Artisan Premium + Design Complexity

Commercial: $1-$5/ct | Fine Natural: $5-$30/ct | Gem Grade: $30-$200/ct | Lander Blue: $200-$500/ct

Frequently Asked Questions

What is the most valuable turquoise?
Lander Blue turquoise from Nevada is generally considered the most valuable, with gem-grade specimens reaching $200-$500+ per carat. The mine produced only about 100 pounds of turquoise before being depleted, making it exceptionally rare. Bisbee turquoise, Persian turquoise, and high-grade Sleeping Beauty are also highly valued varieties.
What is stabilized turquoise?
Stabilization is a process where porous, soft turquoise is impregnated with clear resin to improve hardness and color stability. Most turquoise on the market (estimated 90%+) is stabilized. Stabilized turquoise is significantly less valuable than natural, untreated turquoise of comparable appearance, typically selling for 50-80% less per carat.
How can you tell if turquoise is natural?
Natural turquoise has subtle color variations and will absorb a small drop of water, darkening temporarily. Stabilized turquoise resists water absorption. Under magnification, natural turquoise shows a natural texture, while stabilized specimens may reveal tiny resin-filled fractures. Professional gemological testing using infrared spectroscopy can definitively identify treatment status.
Does turquoise matrix affect value?
Matrix (the host rock visible within turquoise) can either increase or decrease value depending on the pattern and mine origin. Bisbee turquoise is famous for its dark chocolate-brown matrix that creates dramatic spiderweb patterns, which adds significant value. Sleeping Beauty turquoise is prized specifically for its clean, matrix-free appearance. The desirability of matrix is highly dependent on the specific mine and collector preferences.
Is turquoise a good investment?
High-grade natural turquoise from named, depleted mines has appreciated significantly over the past few decades. Bisbee and Lander Blue specimens have increased 300-500% in value since the mines closed. However, the market is highly specialized, and liquidity is limited compared to precious stones. Knowledge of mines, artists, and authentication is essential for investment-grade purchases.

Understanding Turquoise Value and Quality

Turquoise is one of the oldest gemstones known to humanity, prized for over 6,000 years across cultures from ancient Egypt to the American Southwest. Today, fine natural turquoise is increasingly rare as many historic mines have been depleted, driving collector values to unprecedented levels for top-quality specimens.

The turquoise market is uniquely complex because value depends not only on traditional gemstone quality factors (color, clarity, size) but also heavily on mine origin, treatment status, and in the case of finished jewelry, the artist who created the piece. Understanding these factors is essential for making informed purchasing decisions.

Mine Origin and Provenance

Unlike most gemstones where origin affects value modestly, turquoise mine origin can create 10-50x price differences between specimens of similar appearance. The most valuable American mines include Lander Blue (Nevada), Bisbee (Arizona), Number Eight (Nevada), and Lone Mountain (Nevada). Many of these mines are now depleted or closed, making their turquoise increasingly scarce and valuable.

Sleeping Beauty turquoise from Globe, Arizona was one of the most commercially important sources of clean, matrix-free blue turquoise. The mine's closure to turquoise production in 2012 has driven prices upward for remaining inventory. Persian turquoise from the Nishapur mines in Iran has been prized for millennia and remains among the most valuable origins globally.

Color, Matrix, and Treatment

The most valuable turquoise color is a pure, medium-toned blue sometimes called "robin's egg blue" or "Persian blue." Color should be even throughout the stone without mottling or pale areas. Blue-green shades are generally less valued than pure blue, though personal preference plays a significant role in the market.

Treatment status is perhaps the single most impactful value factor. Natural, untreated turquoise that is hard enough for jewelry use without stabilization represents less than 10% of the market and commands significant premiums. Stabilized turquoise, while perfectly suitable for jewelry wear, sells for a fraction of natural prices. Color-enhanced or reconstituted turquoise represents the lowest value tier.
