Loose Cat's Eye Opal Gemstones for jewelry making

Chatoyant Opal for Custom Jewelry

Cat’s Eye Opal is most often cut as a cabochon to enhance the sharp eye effect. These gemstones are ideal for statement rings, pendants, and collector pieces where the moving band of light can be fully appreciated.

Cabochon Cat’s Eye Opals

Because chatoyancy is best displayed on smooth, domed surfaces, most Cat’s Eye Opals are available in oval and round cabochons. Proper orientation during setting ensures the eye appears straight and centered.

Understanding the Cat’s Eye Effect

The cat’s eye phenomenon, also known as chatoyancy, is caused by parallel inclusions or internal structures that reflect light in a narrow band. In fine Cat’s Eye Opal, the eye should be sharp, bright, and clearly defined.

Wholesale Cat’s Eye Opal

We offer competitive pricing on single stones and parcel lots for jewelers and collectors. Our wholesale Cat’s Eye Opal selection includes calibrated sizes suitable for standard jewelry mountings.

October Birthstone Opal

As part of the opal family, Cat’s Eye Opal shares the distinction of being associated with October birthdays. These unique stones make meaningful gifts with both rarity and visual impact.

FAQs

What is a Cat’s Eye Opal?

A Cat’s Eye Opal is an opal gemstone that displays chatoyancy, a bright band of light resembling a cat’s eye. This effect moves across the stone when rotated under a light source.

Are your Cat’s Eye Opals natural?

Yes, all our Cat’s Eye Opal gemstones are natural. Any treatments or enhancements are clearly disclosed on each product page.

Why are Cat’s Eye Opals cut as cabochons?

Cabochon cuts enhance the visibility of the cat’s eye effect. A smooth, domed surface allows the band of light to appear sharp and continuous.

How durable is Cat’s Eye Opal for jewelry?

Opal has a Mohs hardness of approximately 5.5 to 6.5, so Cat’s Eye Opal is best suited for earrings and pendants, or protective ring settings.

What should I look for when buying Cat’s Eye Opal?

Look for a well-centered, bright eye with strong contrast against the body color. The sharper and more distinct the band of light, the higher the quality.

Do you offer calibrated Cat’s Eye Opals?

Yes, we stock calibrated Cat’s Eye Opal stones in popular sizes suitable for standard jewelry mountings.

My experience has always been fantastic. Today I saved 6 gems to email a customer looking for a particular color blend to fit into an east west setting, so her options were limited, but we found one she wanted, deleted all the others in the cart and order the gem she selected. It was helpful to be able to put them in the cart so I could save them until she selected the one she wanted without having to research all of them again.
