TRAINING 13: GOLD COLORS EXPLAINED – HOW TO CREATE WHITE, ROSE AND YELLOW GOLD AND HOW THEY DIFFER IN JEWELLERY MAKING
INTRODUCTION TO THE TRAINING FOR JEWELLERS
Welcome to this jewelry workshop focused on gold colours and their practical differences in gold jewellery making. While gold is most commonly associated with its classic warm yellow tone, combining pure gold with other metals allows jewellers to achieve a wide range of colours — from cool white gold to warm rose gold. Understanding how different gold alloys are created and how they behave during processing is essential for professional jewelry making. Knowledge of gold content directly affects soldering, forming, polishing, durability, and final aesthetics of your jewellery collection.
Jewelry Training Goals:
Understand how alloying metals influence gold colour
Learn the compositions of white, rose, and yellow gold
Discover key differences in processing, soldering, and finishing gold jewellery
This online jewelry course is divided into 4 modules.
MODULE 1: GOLD PURITY AND ALLOY COMPOSITION
Pure Gold (24K)
Contains 99.9% gold
Extremely soft and highly malleable
Rarely used alone in European jewellery design due to low durability
Gold Alloys
To improve hardness and achieve different colours, gold is alloyed with metals such as copper, silver, palladium, nickel, or zinc.
Common gold purities – fineness:
9K (375) – 37.5% gold
14K (585) – 58.5% gold
18K (750) – 75% gold
The alloy composition determines:
color
hardness
melting temperature
workability
Conclusion:
Gold color is always the result of alloying metals. The type and proportion of added metals define both the appearance and mechanical properties of the final material.
MODULE 2: GOLD COLOURS – WHITE, ROSE AND YELLOW GOLD
Yellow Gold
Composition: gold + silver + copper (sometimes zinc)
Characteristics: closest to natural gold color
More silver → lighter tone
More copper → deeper, warmer yellow
Rose Gold
Composition: gold + higher copper content
Characteristics: warm pink to reddish hue
Higher copper = deeper rose/red tone
Popular in modern and romantic jewellery designs
White Gold
Composition: gold + whitening metals (palladium or nickel)
Nickel white gold: harder, durable, but may cause allergies
Palladium white gold alloys: more expensive, slightly warmer white, hypoallergenic gold
Often rhodium plated for bright white finish
Conclusion:
Each gold color is defined by its alloy. The choice of alloy for gold jewellery affects not only appearance but also hardness, durability, and processing behavior.
MODULE 3: PROCESSING AND SOLDERING DIFFERENCES
Hardness and Workability
Yellow gold: most malleable, easiest to form
Rose gold: harder due to copper, requires frequent annealing
White gold: hardest, especially nickel-based alloys
Melting Temperature
Varies depending on alloy and purity
White gold often melts at higher temperatures than yellow or rose gold
Accurate temperature control is critical to avoid discoloration
Soldering Gold
Always match solder color to alloy color
White gold requires specialized solders and higher temperatures
Rose gold needs copper-balanced solder to maintain color consistency
Polishing and Finishing Gold Jewelry
Yellow gold: easy to polish, but softer at lower carats
Rose gold: may darken slightly if not properly finished
White gold: usually rhodium plated after polishing
Conclusion:
Each gold color requires adjusted soldering techniques, temperature control, and finishing methods to achieve professional results.
MODULE 4: PRACTICAL GUIDELINES FOR JEWELRY MAKERS
Choosing Gold for Jewelry Designs
Yellow gold: best for complex soldering and traditional designs
Rose gold: ideal for delicate, romantic jewellery — requires careful annealing
White gold: perfect for diamond settings and modern jewellery collections
Working With Suppliers
Always confirm alloy composition and recommended processing parameters
Consistent suppliers ensure stable color and quality
Care and Maintenance
Yellow gold: easiest to maintain
Rose gold: avoid harsh chemicals
White gold: periodic rhodium re-plating recommended
Skill Development
Test different alloys in practice
Record soldering temperatures and annealing cycles
Experience builds confidence and precision
SUMMARY OF JEWELLERY MAKING ONLINE COURSE
Different gold colors are achieved through alloying pure gold with silver, copper, palladium, or nickel. Yellow gold is the most malleable, rose gold is harder due to copper, and white gold requires specialized soldering and finishing techniques. Choosing the right gold alloy affects not only aesthetics but also durability, workability, and customer comfort. As a jeweler, with proper preparation, matching solders, and precise processing, you can create high quality jewelry in a wide range of gold colors.
