Significance of Gemstone Inclusions & Color in Astrology

For selecting an astrological stone color, inclusion plays a vital role. In ancient astrology, specific gemstone colors are linked with planets, while gemology examines gemstone color, inclusions, transparency, and treatment to assess a stone’s physical characteristics. Understanding both of them will help to make a more informed gemstone choice. 

However, gemstone quality and astrological suitability are not the same thing. A natural and high-quality stone is not only always ideal for the individual birth chart. 

Why Do Gemstone Inclusions & Color Matter in Astrology?

Every stone is linked with particular planets; therefore, color and quality are essential. From a gemological perspective, color is assessed through hue, tone, and saturation, while inclusions are internal characteristics that can reveal information about a gemstone's formation, identity, and sometimes treatment.

This means choosing an astrological gemstone should not be reduced to rules such as "the darkest gemstone is the best" or "the stone must be completely flawless."

Instead, a natural gemstone is identified by these factors: 

• Natural or synthetic origin
• Color and color uniformity
• Transparency
• Clarity and inclusions
• Treatment
• Cut and finish
• Durability
• Astrological suitability

What Are Inclusions in Gemstones?

Gemstone inclusions are internal characteristics present within a gemstone. They can form during crystal growth and may include mineral crystals, needles, fluids, gases, cavities, and fractures.

Some common types include

• Crystal inclusions: Mineral crystals trapped inside the host gemstone.
• Needle inclusions: Fine, elongated crystals that may appear as needles or silk.
• Fingerprint inclusions: Partially healed fractures that create fingerprint-like patterns.
• Fluid inclusions: Tiny cavities containing liquid and sometimes gas.
• Cloud inclusions: Groups of minute inclusions that create a hazy appearance.
• Fractures or feathers: Internal breaks that can affect clarity and, when surface-reaching, durability.

Inclusions are not automatically defects. GIA notes that they can help gemologists identify natural, synthetic, and treated gemstones and, in some cases, determine likely geographic origin. Certain internal features can also create desirable optical effects such as asterism and chatoyancy.

Do Inclusions Prove a Gemstone Is Natural?

No. The presence of inclusions alone does not prove that a gemstone is natural. Gemologists examine the type, combination, and arrangement of inclusions along with other physical and analytical characteristics.

Therefore, a seller's claim that "this gemstone has inclusions, so it must be natural" should not be considered sufficient proof. A reliable laboratory report is a much stronger way to establish a gemstone's identity and treatment status.

Are Gemstone Inclusions Good or Bad for Astrology?

There is no single rule that every inclusion makes an astrological gemstone unsuitable.

Traditional gemstone astrology may regard prominent defects, cracks, and certain visible imperfections as undesirable. Gemology, meanwhile, looks at whether an inclusion affects the stone's appearance, transparency, structural integrity, or durability.

These inclusions need closer attention

• The large or prominent dark inclusions
• Surface-reaching cracks or fractures
• Large cavity inclusions
• Heavy cloudiness that reduces transparency
• Inclusions that affect the gemstone's appearance
• Fractures that may compromise durability

Inclusions which are may be acceptable

• Tiny internal crystals
• Fine needles
• Minor fingerprint-like features
• Small natural growth characteristics
• Inclusions that do not affect stone appearance or durability

The perfect inclusion also differs from one gemstone to another. Some gems naturally have more inclusions, so judging each stone by the same “eye-clean” process will not be justified. GIA's research similarly notes that some gems are rarely eye-clean and that inclusions can sometimes be part of their characteristic appearance.

Does Gemstone Color Matter in Astrology?

Yes, color has an important role in traditional gemstone astrology. Planetary gemstones are traditionally associated with particular colors:

Gemstone	Traditional Planet	Common Color
Ruby	Sun	Vivid red
Pearl	Moon	White to creamy white
Red Coral	Mars	Rich red to reddish-orange
Emerald	Mercury	Vivid green
Yellow Sapphire	Jupiter	Bright yellow
Diamond	Venus	Colorless to white
Blue Sapphire	Saturn	Strong blue
Hessonite	Rahu	Honey to orange-brown
Cat's Eye	Ketu	Greenish, golden, or honey tones

Understanding Hue, Tone & Saturation in Gemstones

Hue

Gemstone hue reflects the basic color of the gemstone; for example, a blue sapphire stone may have slight violet or green hue influence in it. 

Tone

Gemstone tone symbolizes how light or dark the stone color appears. A darker gemstone is not always better. If a stone is excessively dark, its transparency and visual brightness may get reduced. GIA states the ideal combination of hue, tone, and saturation differs from stone to stone. 

Saturation

Saturation stands for the strength or intensity of the stone color. Therefore, evaluating color requires looking at all three factors together rather than judging a stone simply by how dark or bright it appears.

Does a Darker Gemstone Give Better Astrological Results?

Not necessarily. Traditional astrology gives importance to the appropriate color of a planetary gemstone, but there is no universal rule that making the color darker automatically makes the gemstone more powerful.

From a gemological perspective, an overly dark gemstone may actually lose transparency and visual appeal. The ideal color depends on the gemstone itself.

A better evaluation considers:

Hue + Tone + Saturation + Transparency

For example, the color expectations for a ruby should not simply be transferred to an emerald or blue sapphire. Each gemstone has its own quality characteristics.

Gemstone Color vs Clarity: Which Matters More?

It is better not to treat color and clarity as competing factors. A gemstone with excellent transparency but a dull color can be less visually pleasing than a vivid-color stone with minor inclusions. In some cases, the excessive inclusion, fractures, and cloudiness of the stones reduces their transparency and durability. That’s why a buyer's goal should be balance, not perfection. 

Why Inclusions and Color Differ Between Gemstones

These are the biggest mistakes buyers do while buying precious gemstones. They apply the same quality rule to every gemstone. 

Ruby

An attractive red color is an important quality consideration. Minor inclusions can occur naturally, but excessive inclusions may reduce transparency and visual appeal.

Blue Sapphire

Blue Sapphire is traditionally associated with Saturn. Strong color, transparency, and clarity all contribute to its appearance. A very dark stone should not automatically be considered superior.

Emerald

Emeralds commonly contain visible inclusions. Their internal characteristics can be part of the stone's natural appearance, so the focus should be on whether inclusions significantly affect transparency or durability. GIA identifies color as a major factor in emerald quality and notes that highly transparent stones with attractive green color are particularly prized.

Cat's Eye

Cat's Eye demonstrates why inclusions are not always undesirable. Its characteristic chatoyancy is produced by aligned internal features. In this case, the internal structure contributes directly to the optical effect that makes the gemstone distinctive.

These examples show why the statement "all inclusions are bad" is too simplistic.

Do Natural Astrological Gemstones Need to Be Flawless?

It is not necessary; natural stones usually carry internal inclusions formed during their growing process. Some inclusions are only visible under magnification, while others mirror them without magnification. However, it is important that these inclusions not affect these factors: 

• Gemstone beauty
• Gemstone transparency
• Gemstone durability
• Overall quality

Also remember that "natural" does not mean "untreated." A gemstone can be natural but subsequently treated to alter its color or clarity. Inclusions can sometimes provide important clues about treatments, but proper laboratory examination is needed for reliable identification.

Choose Astrological Gemstone Based on Color & Inclusions

If you are looking for an astrological gemstone according to your birth chart, consider these factors: 

1. Confirm astrological suitability

Check whether the gemstone is traditionally appropriate for the native birth chart or not. 

2. Verify natural origin

It is advised to never rely on the visible inclusion to determine stone authenticity. Choose a stone with authentic certification and a laboratory report. 

3. Evaluate color

Before buying, look at the hue, tone, saturation, and color uniformity on the stone. Never assume a dark-colored stone is automatically best. 

4. Check clarity and transparency

Always buy an attractive gemstone without excessive cloudiness or major clarity problems. 

5. Examine inclusions

The minor inclusions are normal, while the large fractures, cavities, and surface-reaching cracks deserves more closer attention. 

6. Check treatment disclosure

The natural gemstones can still be treated to enhance their color and brillance. Always ask whether the stone is treated or not. 

7. Evaluate the gemstone as a whole

Never choose a stone based on carat, color, and price only. Consider origin, color, clarity, inclusions, treatment, transparency, and overall appearance altogether. 

Astrology vs Gemology: What Does Each Evaluate?

It is important to understand where the two disciplines differ.

Gemology evaluates	Traditional astrology considers
Natural or synthetic origin	Planetary association
Color characteristics	Traditional planetary color
Clarity and inclusions	Traditional gemstone quality
Treatment	Traditional suitability
Transparency and durability	Birth chart suitability
Physical identification	Appropriate planetary gemstone

A laboratory certificate can establish important physical facts about a gemstone, but it cannot determine whether that gemstone is suitable for an individual's horoscope. That is a separate astrological consideration.

Final Thoughts

The significance of gemstone inclusions and color in astrology becomes clearer when traditional Jyotish principles and modern gemology are considered together.

Color has a traditional connection with planetary gemstones, while inclusions can provide valuable information about a gemstone's natural formation, clarity, treatment, and identity. Neither should be judged in isolation.

The best astrological gemstone is therefore not necessarily the darkest, clearest, largest, or most expensive stone. It should be appropriate for the birth chart and carefully evaluated for its natural origin, color, transparency, inclusions, treatment, and overall quality.
