Opal Selection Guide

Opals, with their stunning play-of-color and unique patterns, are among the most enchanting gemstones available. However, selecting the perfect opal can be a complex task given the variety of types, colors, and qualities. This comprehensive opal selection guide will answer your questions and help you choose the ideal opal for your needs.

1. What Are the Different Types of Opals?

Answer: There are several types of opals, each with unique characteristics:

• Black Opal: Known for its dark body tone, which enhances the play-of-color. Found primarily in Lightning Ridge, Australia, black opals are among the most valuable.
• White Opal: Also known as light opal, these have a white or light body tone. They are common and found in South Australia.
• Boulder Opal: Contains fragments of opal within the host rock. These opals are durable and often display vibrant colors.
• Crystal Opal: Known for its transparent to translucent body, which can exhibit brilliant play-of-color. Crystal opals are highly prized for their clarity.
• Fire Opal: Distinguished by its vivid orange, yellow, or red body color, with or without play-of-color. Mainly found in Mexico.

2. How is Opal Graded?

Answer: Opal grading involves evaluating several factors:

• Color: The intensity and range of colors. The more vibrant and diverse the play-of-color, the more valuable the opal.
• Clarity: The transparency and purity of the opal. Eye-clean opals with minimal inclusions are more desirable.
• Pattern: The arrangement of colors within the opal. Rare patterns like harlequin and flagstone increase the gemstone’s value.
• Body Tone: The underlying color of the opal when it’s not displaying play-of-color. Darker body tones generally enhance the visibility of the play-of-color.
• Cut: The precision and quality of the cut, which affects the gem’s overall appearance and brilliance.

3. What Should I Look for in Opal Color?

Answer: When selecting an opal, consider the following color aspects:

• Intensity: Bright, vivid colors are more appealing and valuable than dull or faint ones.
• Color Range: Opals displaying a wide range of colors, especially reds and blues, are highly prized.
• Evenness: Consistent color distribution without dull or dead spots is preferred.

4. How Important is the Pattern in Opals?

Answer: The pattern is a significant factor in determining an opal’s value and appeal:

• Harlequin Pattern: A rare and highly sought-after pattern featuring a mosaic of large, blocky colors.
• Pinfire Pattern: Consists of tiny, pinpoint flashes of color scattered throughout the gem.
• Ribbon Pattern: Bands or ribbons of color running through the opal.
• Flash Pattern: Large areas of color that appear and disappear as the opal is moved.

5. What About the Opal’s Body Tone?

Answer: The body tone of an opal affects how its play-of-color is perceived:

• Black or Dark Tone: Enhances the play-of-color, making it appear more vibrant.
• White or Light Tone: Produces a softer, more subtle play-of-color.
• Crystal Opal: Can range from transparent to translucent, often showcasing brilliant play-of-color.

6. How Should I Choose an Opal Based on Its Cut?

Answer: The cut of an opal impacts its brilliance and overall appearance. Look for:

• Symmetry: A well-proportioned and symmetrical cut enhances the gem’s beauty.
• Polish: A high-quality polish brings out the opal’s luster and play-of-color.
• Shape: Common shapes include oval, round, and freeform. Choose a shape that complements your intended use.

7. Are There Treatments to Consider?

Answer: Some opals undergo treatments to enhance their appearance:

• Dyeing: Used to enhance or change the body color. Treated opals are generally less valuable.
• Smoking: A treatment to darken the body tone, enhancing the play-of-color.
• Stabilization: Involves impregnating the opal with a clear resin to improve durability. Common in boulder opals.

8. How Can I Ensure the Opal is Authentic?

Answer: To ensure you’re buying a genuine opal, consider the following:

• Certification: Purchase from reputable dealers who provide certification from recognized gemological laboratories.
• Inspection: Examine the opal under various lighting conditions to assess its play-of-color and clarity.
• Consultation: Seek advice from a professional gemologist or experienced jeweler.

9. How Should I Care for My Opal?

Answer: Proper care ensures the longevity and beauty of your opal:

• Cleaning: Use mild soap and water. Avoid harsh chemicals and ultrasonic cleaners.
• Storage: Store opals separately in a soft cloth or padded jewelry box to prevent scratches and dehydration.
• Handling: Avoid exposing opals to extreme temperatures and direct sunlight for extended periods.
