Solid gold jewelry has been treasured across cultures and centuries—not only for its beauty, but for its permanence. As Olaeda prepares to introduce more solid gold designs in 2026, this guide is designed to help you understand exactly what solid gold is, how purity is measured, and why it remains one of the most meaningful jewelry investments you can make.

Whether you’re buying your first solid gold piece or building a collection meant to be passed down, education is the foundation of confident purchasing.

What Does “Solid Gold” Really Mean?

Solid gold jewelry is made entirely of gold alloy throughout the piece. It is not plated, coated, or bonded over a base metal. This distinction matters.

Because pure gold is naturally soft, it is mixed with small amounts of other metals (called alloys) to improve durability while preserving intrinsic value.

Key takeaway: Solid gold never wears away. With proper care, it can last for generations.

Gold Karats Explained: How Purity Is Determined

Gold purity is measured using the karat (K) system, based on a 24-part scale. The higher the karat, the greater the percentage of gold in the piece.

24K Gold – 99.9% Pure Gold

• Purity: 99.9%

• Color: Deep, rich yellow

• Durability: Very soft

• Best for: Investment gold, ceremonial pieces, collectors

24K gold is the purest form of gold available. While highly valuable, it is too soft for most everyday jewelry and is rarely used for wearable designs.

22K Gold – 91.6% Gold

• Purity: 91.6%

• Color: Saturated yellow

• Durability: Soft, but stronger than 24K

• Best for: High-value heirloom and cultural jewelry

22K gold offers exceptional purity and visual richness, often chosen for special-occasion pieces intended to be cherished rather than worn daily.

18K Gold – 75% Gold

• Purity: 75%

• Color: Warm, luxurious yellow

• Durability: Excellent balance of strength and purity

• Best for: Fine jewelry and heirloom-quality everyday wear

18K gold is widely regarded as the gold standard for fine jewelry. It offers substantial intrinsic value while remaining durable enough for regular wear—making it ideal for legacy pieces.

14K Gold – 58.5% Gold

• Purity: 58.5%

• Color: Slightly lighter yellow

• Durability: Very strong and scratch-resistant

• Best for: Daily wear, engagement rings, active lifestyles

14K gold is the most popular choice in North America. Its durability makes it a practical option while still retaining long-term value.

10K Gold – 41.7% Gold

• Purity: 41.7%

• Color: Pale yellow

• Durability: Highly durable

• Best for: Budget-conscious jewelry

While legally classified as gold, 10K contains less intrinsic gold value and is typically lighter in color.

Understanding Gold Markings & Hallmarks

Authentic solid gold jewelry is stamped with hallmarks that indicate purity and authenticity.

Common stamps include:

• 999 or 24K – Pure gold

• 916 or 22K – 91.6% gold

• 750 or 18K – 75% gold

• 585 or 14K – 58.5% gold

• 417 or 10K – 41.7% gold

You may also see:

• A maker’s mark identifying the brand or jeweler

• A country of origin stamp

Hallmarks are an important indicator of value and transparency.

Solid Gold vs Gold-Plated & Gold-Filled Jewelry

Not all “gold” jewelry is created equal.

• Gold-plated: A thin layer of gold over base metal; will wear off

• Gold-filled: Thicker gold layer bonded to base metal; longer-lasting, but not permanent

• Solid gold: Gold alloy throughout; never wears away

For longevity, resale value, and heirloom potential, solid gold is unmatched.

Is Solid Gold Jewelry a Good Investment?

While jewelry should never replace traditional financial investments, solid gold offers tangible, enduring value:

• Gold historically retains value over time

• Solid gold can be resold or melted based on market prices

• It is wearable wealth—beautiful and functional

When thoughtfully designed, solid gold jewelry exists at the intersection of sentiment and security.

Why Solid Gold Is the Ultimate Heirloom

Solid gold jewelry is uniquely suited to be passed down because it:

• Does not degrade or expire

• Can be resized, repaired, or redesigned

• Carries emotional and material value

Heirlooms are not about trends—they are about permanence. Solid gold tells a story that grows richer with time.

Caring for Solid Gold Jewelry

To keep your pieces beautiful:

• Clean gently with warm water and mild soap and or a polishing cloth

• Store separately to prevent scratching

• Remove during heavy physical activity

With minimal care, solid gold jewelry will last for decades.
