Question:  What Are the Most Common Treatments Applied to Onyx?

Answer : The most common treatment for Onyx is dyeing, used to enhance or even out its color, especially to achieve a deep, uniform black. Onyx may also undergo heat treatment to alter or intensify its natural colors, and surface treatments like polishing and waxing to improve luster.

Question: Can Onyx Lose Its Color Over Time?

Answer : Dyed Onyx can sometimes fade, especially if frequently exposed to harsh chemicals or intense sunlight. However, natural, untreated Onyx tends to retain its color over time. Proper care and maintenance can significantly prolong the color life of treated Onyx.

Question:  Is Onyx Always Black and White?

Answer : While the classic Onyx features black and white banding, Onyx actually comes in a variety of colors, including red, green, and blue. These colors can be natural or a result of dye treatments.

Question: How Can I Tell if Onyx Has Been Dyed?

Answer :  Identifying dyed Onyx often requires professional gemological equipment. However, uneven color distribution or a concentration of color in cracks or pores can be visual indicators. When in doubt, it’s best to consult with a gemologist.

Question: Does Treating Onyx Diminish Its Value?

Answer : Yes, typically, treated Onyx, especially dyed Onyx, is less valuable than its natural counterpart. However, the skillfulness of the treatment and the stone’s overall appearance can mitigate this impact to some extent.

Question: Are There Any Special Care Instructions for Treated Onyx?

Answer : Treated Onyx should be kept away from harsh chemicals and prolonged exposure to direct sunlight. It’s also recommended to clean it with mild soap and water, avoiding ultrasonic cleaners.

Question (Myth) : Onyx Is a Fragile Gemstone and Easily Damaged.

Debunked: Onyx, being a variety of chalcedony, has a good degree of hardness (6.5 to 7 on the Mohs scale). While it’s not as hard as diamonds or sapphires, it’s still relatively durable for everyday wear if properly cared for.

Question (Myth) : All Onyx Is Naturally Black.

Debunked: While black is the most familiar color, Onyx naturally occurs in a range of colors including whites, reds, and greens. Black Onyx, especially the deep black variety, is often the result of dye treatments.
