What Is 20 Carat Gold? Hallmark Number and Resale Value Explained
Gold purity directly affects durability, appearance, price, and resale value. While most buyers are familiar with 22K and 24K gold, 20 Carat Gold, also known as 20K Gold, is gaining attention for its balance between high gold content and enhanced strength. It sits comfortably between traditional jewellery gold and lower-purity designer gold.

Understanding what 20K Gold means, how it is hallmarked, and where it fits in the gold purity spectrum helps buyers make smarter purchasing and resale decisions. This guide explains 20 Carat Gold in detail, focusing on purity, characteristics, hallmarking, and practical usage.
What Is 20 Carat Gold?
20 Carat Gold (20K Gold) is a gold alloy that contains 83.33% pure gold, with the remaining 16.67% composed of alloy metals such as copper, silver, or zinc. Gold purity is measured on a 24-part scale, and 20 carats indicate that 20 out of 24 parts are pure gold.
This composition makes 20K Gold significantly stronger than higher-purity gold while still retaining a rich gold appearance and substantial intrinsic value.
Definition Overview of 20 Carat Gold
- Gold Content: 83.33% pure gold
- Alloy Content: 16.67% strengthening metals
- Purity Classification: High-purity gold alloy
- Common Name: 20K Gold
- Primary Usage: Jewellery and ornaments
Why 20 Carat Gold Exists in the Gold Market
Pure gold is naturally soft. As purity increases, durability decreases. The purpose of introducing 20 Carat Gold is to create a balance between gold richness and structural strength, especially for jewellery meant for regular wear.
20K Gold exists in the market because it:
- Offers better durability than 22K and 24K gold
- Supports intricate jewellery designs more effectively
- Reduces deformation, bending, and scratch damage
- Costs less than higher-purity gold while retaining strong value
This balance makes 20 Carat Gold particularly suitable for buyers prioritising longevity over maximum purity.
Physical Characteristics of 20 Carat Gold
20K Gold has distinct physical properties that differentiate it from both higher and lower karat gold.
- Colour: 20 Carat Gold displays a warm yellow tone that is slightly less intense than 22K or 24K gold due to added alloy metals.
- Strength: The alloy composition increases hardness, allowing 20K Gold to resist bending, dents, and surface scratches more effectively.
- Weight: Because of lower pure gold content, 20 Carat Gold weighs marginally less than higher-karat gold of the same volume.
- Finish: Despite lower purity, 20K Gold maintains a smooth, lustrous finish suitable for premium jewellery.
- Workability: Jewellers find 20K Gold easier to mould into complex designs without compromising structural integrity.
Is 20 Carat Gold Considered Pure Gold?
20 Carat Gold is classified as high-purity gold, but it is not considered pure gold in technical terms. Pure gold is defined as 24 carat or 99.9% purity.
Key points to understand:
- 20K Gold contains more gold than 18K but less than 22K
- It retains strong intrinsic value due to high gold percentage
- It is not used for investment bullion like bars or coins
- Its value includes both gold content and craftsmanship
Therefore, 20 Carat Gold is best suited for jewellery rather than pure investment purposes.
What Is the Hallmark Number for 20 Carat Gold?
Hallmarking certifies gold purity and protects buyers from fraud. In India, hallmarking is regulated by the Bureau of Indian Standards (BIS).
The hallmark number for 20 Carat Gold is:
- 833
This number signifies that the gold contains 83.3% pure gold, which corresponds exactly to 20K Gold on the carat scale.

20 Carat Gold vs Other Gold Purities (Overview)
| Gold Purity | Gold Content | Durability | Typical Use |

20 Carat Gold is suitable for buyers who:
- Want jewellery stronger than 22K gold

However, for bullion investment or highest resale efficiency, higher-purity gold may be more suitable.
What Is the Resale Value of 20 Carat Gold?
The resale value of 20 Carat Gold depends primarily on its gold purity, current market price, and overall condition. Since 20K Gold contains 83.33% pure gold, its resale value is lower than 22K or 24K gold but higher than 18K gold.
When selling 20K Gold jewellery, buyers evaluate only the gold content, not the design or emotional value. This makes understanding resale dynamics essential before purchasing.
How Is the Resale Value of 20K Gold Calculated?
Gold buyers follow a systematic and transparent process to calculate the resale value of 20 Carat Gold.
- Live Gold Market Rate: The current 24K gold rate is used as a reference, then adjusted proportionally to 83.33% purity.
- Net Gold Weight: Only the weight of the gold portion is considered, excluding stones, clasps, or non-gold components.
- Purity Percentage: Since 20K Gold equals 83.33% purity, buyers multiply weight by this factor during valuation.
- Hallmark Verification: BIS-hallmarked 20 Carat Gold receives quicker and more accurate valuation.
- Stone Deduction: If jewellery contains gemstones, their weight is deducted from the total weight before valuation.
- Testing Method Used: XRF testing ensures accurate purity assessment without damaging jewellery.
- Local Market Competition: Cities with more organised gold buyers may offer slightly better resale rates.
Does 20 Carat Gold Have Deductions During Resale?
Yes, 20K Gold resale involves certain deductions, mainly because it is jewellery-grade gold.
Common Deductions Applied
- Making Charges: Making charges paid during purchase are not recovered during resale.
- Stone and Gem Weight: The weight of stones or non-gold materials is deducted from the total.
- Purity Adjustment: Buyers value only 83.33% gold content, not the full weight.
- Minor Melting Charges: Some buyers apply small fees if jewellery must be melted.
- Non-Hallmarked Discount: Slight deductions may apply if the jewellery lacks BIS hallmarking.
What Is NOT Deducted
- Age of Jewellery: Old and new 20K Gold carry similar value if purity is unchanged.
- Surface Wear: Scratches or dents do not significantly affect value, as gold is melted.
20 Carat Gold vs 22K Gold vs 24K Gold (Resale Comparison)

| Resale Value per Gram | Moderate | High | Highest |
| Making Charge Loss | High | High | None |
| Investment Suitability | Low | Moderate | Excellent |
| Jewellery Durability | High | Moderate | Very Low |

- Jewellery-Based Investment: The value of 20 Carat Gold depends more on wearability and craftsmanship rather than long-term storage or pure price appreciation potential.
- Long-Term Wear Value: 20K Gold delivers returns through extended usability and durability, offering practical value rather than relying solely on gold price appreciation cycles.

FAQs
What is the hallmark number for 20 Carat Gold?
The hallmark number for 20 Carat Gold is 833, which confirms the gold contains 83.33 percent pure gold. This purity mark is issued under the Bureau of Indian Standards hallmarking system in India. A BIS hallmarked 20K Gold item also includes the BIS logo, assaying centre mark, jeweller identification, and year code. These markings ensure authenticity, protect buyers from fraud, and help sellers receive accurate valuation during resale transactions for jewellery and ornaments across Indian retail and resale markets nationwide.
Does 20K Gold have good resale value?
20K Gold has moderate resale value because only 83.33 percent of its weight is pure gold. During resale, buyers deduct making charges, stone weight, and alloy content. Hallmarked 20 Carat Gold generally receives better pricing and faster evaluation. Although resale value is lower than 22K or 24K gold, 20K Gold still performs better than lower purities like 18K, making it a reasonable option for jewellery owners planning future resale through organised gold buyers and transparent valuation processes nationwide today consistently.
Is 20 Carat Gold suitable for daily wear?
Yes, 20 Carat Gold is suitable for daily wear because it is stronger than higher purity gold. The added alloy metals improve hardness and resistance to bending or scratches. This makes 20K Gold ideal for rings, bangles, chains, and earrings worn regularly. It offers a good balance between durability and gold richness, making it popular for jewellery that must withstand frequent use without losing structural integrity over long periods of time in everyday conditions safely and reliably for users worldwide.
Is 20 Carat Gold a good investment choice?
20 Carat Gold is not considered ideal for pure investment purposes. Investment gold typically requires very high purity for easy valuation and liquidity. Since 20K Gold contains alloy metals, its resale involves deductions. It is better suited for jewellery value rather than wealth storage. Investors seeking long term appreciation, inflation protection, and quick resale usually prefer 22K or 24K gold bars or coins instead for secure portfolio diversification and stable long range financial planning goals globally today across markets worldwide.
Why is hallmarking important for 20 Carat Gold?
Hallmarking is important for 20 Carat Gold because it confirms purity and authenticity. A BIS hallmark assures buyers that the gold contains 83.33 percent pure gold. Hallmarked 20K Gold is easier to resell and valued more accurately. Without hallmarking, buyers may apply conservative pricing or require additional testing. Therefore, purchasing BIS hallmarked jewellery protects consumers and improves trust, transparency, and resale outcomes during gold transactions with professional buyers across India and organised markets consistently over time and usage cycles nationwide.
