925 Sterling Silver
The 7.5% Alloy in S925 Silver: More Than Just "Other Metals"S925 silver consists of 92.5% pure silver and 7.5% other metals (typically copper). This precise ratio is deliberate.
Core Function: Pure silver (e.g., S999) is too soft for daily-wear jewelry. The added copper and other metals significantly increase the alloy's hardness, strength, and wear resistance, enabling the jewelry to withstand daily use, maintain its shape, while retaining good malleability for processing.
Our Practice: At NAGOSA, we strictly control the composition of this 7.5% alloy to ensure consistent performance during casting, shaping, and polishing, guaranteeing the structural integrity of the product from the source.
Brass
Characteristics: Copper is a highly ductile metal with a distinctive reddish-brown color.
Aesthetics: Copper is favored for its warm and rustic hue, adding a unique and vintage charm to jewelry.
Care: Copper will develop an oxide layer over time, but this oxide layer is often appreciated for its antique appeal.
Stainless Steel
Features: Renowned for its exceptional durability, corrosion resistance, and competitive price.
Aesthetics: Stainless steel boasts a stylish and modern look, making it a popular choice for contemporary jewelry.
Durability: Resistant to fading, scratches, and rust, making it suitable for everyday wear.
Gemstone
We specialize in crafting custom jewelry with a complete spectrum of stones—from the timeless allure of natural diamonds, sapphires, and emeralds to the vibrant palette of semi-precious stones and the brilliant consistency of lab-created gems.
More than just sourcing, we provide strategic guidance. We help you select the perfect stone to match your brand’s identity and budget, whether it’s for a high-value luxury piece or a trend-driven collection.
Pearls Jewelry
For centuries, pearls have reigned as the "Queen of Gems," symbolizing purity, wisdom, and timeless elegance.
Unlike mined stones, each pearl is a unique organic creation, formed by mollusks through a remarkable natural process.
At NAGOSA, we understand that selecting the right pearls is both an art and a strategic business decision.
This guide will navigate you through the world of pearls—from understanding their origins to making informed choices for your jewelry line。
