What Are Gemstones? Understanding the Fundamentals
Definition and Basic Characteristics
A gemstone is a piece of mineral crystal that, when cut and polished, becomes suitable for jewelry or ornamental purposes. However, not every beautiful mineral qualifies as a gemstone.
Three Essential Qualities Define Gemstones:
- Beauty – Attractive color, luster, or optical phenomena
- Durability – Ability to withstand wear and maintain appearance
- Rarity – Limited natural occurrence that creates value
Some organic materials like amber, pearl, and coral are also classified as gemstones despite not being minerals.
The Difference Between Precious and Semi-Precious Stones
Traditionally, the gemstone world divided stones into two categories:
Precious Stones (The “Big Four”):
- Diamonds
- Rubies
- Sapphires
- Emeralds
Semi-Precious Stones:
- All other gemstones (amethyst, topaz, garnet, etc.)
However, this classification has become outdated. Many so-called “semi-precious” stones like alexandrite, paraiba tourmaline, or fine jade can exceed the value of modest-quality precious stones.
Modern gemologists prefer classifying stones by their actual market value, rarity, and quality rather than historical categories.
Types of Gemstones: A Comprehensive Classification
Natural vs. Synthetic vs. Treated Gemstones
Understanding these categories is crucial for making informed purchases:
| Type | Description | Value | Examples |
|---|---|---|---|
| Natural | Formed in nature, minimal human intervention | Highest | Unheated Kashmir sapphires |
| Treated/Enhanced | Natural stones improved through standard processes | Moderate to High | Heat-treated rubies |
| Synthetic | Lab-created with identical properties to natural | Lower | Lab-grown diamonds |
| Simulants | Materials that mimic gemstones | Lowest | Cubic zirconia for diamonds |
Important Note: Treated stones are still natural and represent the majority of the gemstone market. Treatment isn’t deceptive if properly disclosed.

The Four C’s: How to Evaluate Gemstone Quality
Similar to diamond grading, colored gemstones are evaluated using specific criteria. Understanding these factors helps you assess value and make better purchasing decisions.
Color – The Most Important Factor
For colored gemstones, color accounts for 50-70% of the value. Three components determine color quality:
1. Hue – The basic color (red, blue, green, etc.)
- Primary hue should dominate
- Secondary hues acceptable but shouldn’t overpower
- Example: Blue sapphire may have slight violet, but blue should dominate
2. Tone – How light or dark the color appears
- Scale ranges from colorless (0) to black (10)
- Most valuable stones fall between 4-7
- Too light appears washed out
- Too dark appears black or murky
3. Saturation – Color intensity and purity
- Highest saturation = vivid, pure color
- Lower saturation = grayish or brownish modifiers
- Vivid, highly saturated colors command premium prices
Ideal Color Characteristics by Gemstone:
| Gemstone | Ideal Color |
|---|---|
| Ruby | Pure red with slight blue undertone (“pigeon blood”) |
| Blue Sapphire | Pure blue, medium to medium-dark tone |
| Emerald | Vivid green with slight blue undertone |
| Amethyst | Deep purple with red flashes |
| Aquamarine | Medium blue without green |
Clarity – Understanding Inclusions
Clarity refers to the presence (or absence) of inclusions and blemishes.
Types of Clarity Features:
- Inclusions: Internal characteristics (crystals, fractures, clouds)
- Blemishes: Surface characteristics (scratches, pits, chips)
Clarity Expectations Vary by Gemstone Type:
Type I (Eye-Clean Expected):
- Aquamarine, blue topaz, citrine, zircon
- These should have no visible inclusions to the naked eye
Type II (Minor Inclusions Accepted):
- Ruby, sapphire, garnet, peridot, tourmaline
- Slight inclusions acceptable and common
Type III (Inclusions Expected):
- Emerald, red tourmaline, watermelon tourmaline
- Almost always included; heavily included stones still valuable if color is exceptional
Key Point: A “clean” emerald with vivid color is rarer than a flawless diamond. Clarity standards are stone-specific, not universal.
Cut – Maximizing Beauty
The cut determines how well a stone displays its color and how much it sparkles. Unlike diamond cutting, which follows standardized proportions, colored gemstone cutting prioritizes color display.
Cut Quality Factors:
- Proportions: Depth and width ratios affect color and brilliance
- Symmetry: Even facet alignment and shape
- Polish: Surface smoothness affecting luster
- Face-up appearance: How the stone looks when viewed from above
Common Cut Styles:
- Brilliant Cut: Maximizes sparkle (diamonds, colorless stones)
- Step Cut: Emphasizes color (emerald cut, baguette)
- Mixed Cut: Combines both styles
- Cabochon: Smooth, dome-shaped (opals, jade, star stones)
Signs of Poor Cutting:
- Visible windowing (seeing through the stone)
- Excessive weight retention at the bottom
- Asymmetrical or misaligned facets
- Poor polish showing scratches
Carat Weight – Size and Value
Carat is simply a unit of weight (1 carat = 200 milligrams or 0.2 grams). However, size perception varies by gemstone density.
Important Considerations:
- Price per carat increases exponentially with size for rare stones
- A 2-carat ruby isn’t twice the price of 1-carat; it’s 3-4 times more
- Density affects size appearance: Sapphire appears smaller than diamond at same carat weight
- Cut affects perceived size: Well-cut stones look larger than poorly cut ones
Size Categories:
| Category | Carat Weight | Best For |
|---|---|---|
| Melee | Under 0.20ct | Accent stones |
| Small | 0.20-0.50ct | Delicate jewelry |
| Medium | 0.50-2.00ct | Everyday wear |
| Large | 2.00-5.00ct | Statement pieces |
| Very Large | Over 5.00ct | Collectors, investment |

The Science Behind Gemstones
How Gemstones Form in Nature
Formation Processes:
Igneous Formation
- Crystallization from molten rock (magma/lava)
- Examples: Diamond (high pressure), peridot, tanzanite
- Deep earth conditions required
- Volcanic eruptions bring to surface
Metamorphic Formation
- Transformation under heat and pressure
- Examples: Ruby, sapphire, emerald, jade
- Existing rocks recrystallize
- Mountain-building processes
Sedimentary Formation
- Precipitation from water solutions
- Examples: Opal, turquoise, malachite
- Surface or near-surface formation
- Weathering and erosion processes
Crystal Systems and Their Impact
Seven Crystal Systems:
- Cubic: Diamond, garnet, spinel
- Hexagonal: Emerald, aquamarine, ruby, sapphire
- Tetragonal: Zircon, rutile
- Orthorhombic: Topaz, peridot, tanzanite
- Monoclinic: Moonstone, jade, kunzite
- Triclinic: Labradorite, turquoise
- Trigonal: Quartz, tourmaline, calcite
Why It Matters:
- Affects optical properties
- Determines cleavage directions
- Influences durability
- Creates unique optical effects
The Mohs Hardness Scale
Understanding hardness helps predict durability:
| Hardness | Minerals | Jewelry Suitability |

Frequently Asked Questions (FAQs)
How can I tell if a gemstone is real without professional equipment?
While definitive identification requires gemological equipment, several tests can provide clues. Real gemstones typically feel cool to the touch and stay cool longer than glass or plastic. They’re usually heavier than synthetic imitations. Under 10x magnification, natural stones show characteristic inclusions or growth patterns, while glass contains bubbles. Temperature changes affect real stones differently (they conduct heat slowly). However, for expensive purchases, always get certification from recognized labs like GIA or IGI. Many synthetic stones are chemically identical to natural ones and can only be distinguished through advanced testing.
Why do similar-looking gemstones have vastly different prices?
Price variations reflect numerous factors invisible to untrained eyes. Treatment status significantly affects value – an unheated ruby may cost 5-10 times more than a heated one of similar appearance. Origin matters at the high end (Burmese rubies vs. African rubies). Quality differences in color saturation, clarity grade, and cut precision create huge price gaps. A stone with vivid, pure color costs exponentially more than one with gray or brown modifiers. The seller’s markup varies greatly (retail jeweler vs. direct-from-cutter). Certification from prestigious labs can add to the price but provides important verification. Size increases value exponentially, not linearly.
What’s the difference between lab-grown and natural gemstones, and which should I buy?
Lab-grown gemstones are chemically, physically, and optically identical to natural stones but created in laboratories in weeks rather than forming naturally over millions of years. They cost 60-80% less than equivalent natural stones, have minimal environmental impact, and offer guaranteed ethical sourcing. Natural gemstones are geologically formed, each unique, with historical and rarity value that many collectors prefer. For everyday jewelry where appearance and durability matter most, lab-grown offers excellent value. For investment, collecting, or sentimental pieces, many people prefer natural stones. The choice depends on your priorities: budget, ethics, traditional value, or personal preference. Both are “real” gemstones – the distinction is origin, not authenticity.
How often should I have my gemstone jewelry professionally inspected and cleaned?
Frequency depends on wear patterns and stone type. For daily-wear rings (especially engagement rings), annual professional inspection is recommended to check prongs, settings, and stone security. Delicate stones like emerald, opal, or tanzanite benefit from inspection every 6 months if worn regularly. Professional cleaning can be done during these inspections. Between professional services, clean hard stones (diamond, ruby, sapphire) monthly at home with warm soapy water. Moderate-hardness stones need gentler cleaning every 2-3 months. Very soft stones (pearl, amber, turquoise) should only be wiped with a damp cloth after wearing. Emeralds may need re-oiling every 2-5 years. Always remove jewelry before activities that could damage stones.
Are treated gemstones less valuable, and should I avoid them?
Treated gemstones are natural stones that have been enhanced through accepted industry practices and represent the majority of the market. They are NOT less desirable when properly disclosed and fairly priced. Heat treatment (used on 95%+ of rubies and sapphires) is permanent, stable, and doesn’t affect durability – it simply brings out color that would otherwise be hidden. Emerald oiling is nearly universal and accepted. The key is appropriate pricing: treated stones should cost less than untreated equivalents. Problems arise only when treatments aren’t disclosed or when treated stones are sold at untreated prices. For most buyers, treated stones offer excellent value – beautiful, durable gemstones at accessible prices. Untreated stones are for collectors and investors willing to pay significant premiums for rarity.
