At DVN Jewelry, purity is not just a number — it is the foundation of design, durability, and manufacturing excellence.
Gold is one of the most beautiful and versatile metals used in jewelry. But what many customers do not realize is that the purity of gold directly shapes the final design, strength, finish, and long-term durability of any jewelry piece. At DVN Jewelry, choosing the right karat is a scientific process backed by years of manufacturing expertise.
In this blog, we decode the science behind 18K, 20K, and 22K gold, and how DVN selects the perfect purity to match every design and application.
🌟 Understanding Purity: What Makes 18K, 20K & 22K Different?
22K Gold (91.6% Pure): The Traditional Standard
22K gold has a rich yellow tone, making it the most preferred for bangles, chains, and traditional wear.
But due to its higher gold content, it is softer, which means designs requiring flexibility or slight movement work better than sharp, rigid structures.
Best for:
-
Classic bangles
-
Mangalsutras
-
Chains
-
Wedding jewelry
DVN Advantage:
DVN ensures accurate alloying to maintain perfect hardness while preserving the natural glow of 22K.
20K Gold (83.3% Pure): The Perfect Balance
20K gold holds a unique position between strength and purity. It gives the richness of 22K but offers more durability similar to lower karat gold.
Best for:
-
Patterned bangles
-
Lightweight designs
-
Contemporary jewelry
-
Everyday wear items
Why DVN Chooses It:
DVN uses 20K for designs where both refined color and structural strength are needed. It allows sharper cuts, better durability, and precise detailing.
18K Gold (75% Pure): Strength Meets Styling
18K is the strongest and most design-friendly among the three. It blends beautifully with gemstones and is widely used in modern, geometric, or intricate patterns.
Best for:
-
Fine detailing
-
Diamond/CZ jewelry
-
Casting jewelry
-
International styles
DVN Advantage:
DVN uses 18K in designs requiring advanced techniques like
-
micro-setting
-
complex CNC patterns
-
delicate textures
-
high-tensile assembly
🔧 How Gold Purity Shapes Design and Techniques at DVN
1. Purity Influences Strength
Higher purity means softer metal.
-
22K is ideal for curved, rounded, smooth designs.
-
18K & 20K are perfect for sharp edges, tight patterns, and precision work.
2. Purity Affects Stone Setting
-
18K grips stones more securely due to higher hardness.
-
22K may not hold micro stones tightly, so DVN adapts setting techniques based on the karat.
3. Purity Determines Manufacturing Technique
DVN selects purity based on the process:
-
22K for handcrafting & hollow work
-
20K for patterned bangles and everyday designs
-
18K for casting, CNC, laser-cutting & stone jewelry
4. Color & Finish Depend on Karat
-
22K offers deep yellow richness.
-
20K provides a slightly softer gold tone.
-
18K gives a subtle, modern gold shade ideal for global markets.
