Five Different Colors of Opal Stones ~ Pink, Blue, Yellow, Orange & Green

Five Colors of Opals

Besides the more familiar base colors of white and black, we will explore five other base colors of opals: pink, blue, yellow, orange, and green. Pink opal only occurs as a common opal (no play of color) but the others can occur as both common opal and precious opal formations (with a play of color). We'll explore their origins, rarity, and some famous examples that have captured the world's imagination.

1. Pink Opal

Pink opal, often referred to as the "stone of hope," is primarily found in Peru, which is renowned for producing the most vibrant and uniformly colored pink opals. These opals range from a soft blush to a deep rose hue, reminiscent of a serene sunrise. Pink opals are a type of common opal and do not exhibit play of color. Instead, they possess a soothing, milky appearance.

Pink opals are relatively rare, with significant deposits found in Peru, Mexico, and the United States (particularly in Oregon and Idaho). Australian pink opals, which are actually opalized radiolarite, are also notable but less common.

While pink opals may not be as well-known as their black or fire counterparts, their unique beauty has made them a favorite among collectors and jewelry designers. The Peruvian pink opal, in particular, is highly prized for its intense color and clarity.

2. Blue Opal

Blue opal is another stunning variety, with colors ranging from deep teal to light sky blue. Peru is again a major source, producing both common and precious blue opals. The Peruvian blue opal, often referred to as the "Andean opal," is known for its tranquil, ocean-like hues. These opals can sometimes display a subtle play of color, adding to their allure.

Blue opals are relatively rare, with notable sources including Peru, Brazil, Slovakia, and the United States (particularly in Nevada and Oregon). The Paraiba opal, a rare blue-green variety, is especially sought after.

One of the most popular blue opals is the "Owyhee blue opal" from Oregon, known for its striking pastel blue shades. These opals are a recent discovery and have quickly gained popularity for their unique color and beauty.

3. Yellow Opal

Yellow opal, with its sunny and cheerful hues, ranges from pale lemon to deep golden yellow. This variety is primarily found in Australia, Ethiopia, and Mexico. Yellow opals can exhibit a vibrant play of color, making them highly desirable for jewelry.

Yellow opals are considered rare due to their limited sources and the specific conditions required for their formation. The presence of iron oxides gives these opals their distinctive yellow color.

While there are no widely known famous yellow opals, their bright and inviting color makes them a favorite among gemstone enthusiasts. The Mexican fire opal, which can exhibit yellow hues, is particularly notable for its fiery play of color.

5. Green Opal

Green opal, with its lush and verdant hues, is primarily found in Australia, Brazil, and the United States. These opals can range from pale mint green to deep forest green and may exhibit a subtle play of color.

Green opals are relatively rare, with significant deposits in Australia and Brazil. The unique conditions required for their formation make them a sought-after variety.

One of the most famous green opals is the "Olympic Australis," discovered in Australia. Weighing an astounding 17,000 carats, this opal is one of the largest and most valuable ever found.
