Premium 18K Gold Plating
Our gold pieces are made with 18k gold that is at least 1 micron thick (which is 10x thicker than standard gold plating), layered over high-quality S925 sterling silver (never brass!).
Why Premium 18K Gold Plating?
- Lasting Shine – Long-lasting shine due to stronger and thicker gold layer
- Improved Tarnish Resistance – Extra thickness means greater resistance against tarnishing and wear
- Kind to Your Skin – Hypoallergenic, great for even sensitive skin types
- Accessible – Enjoy the timeless look and feel of solid gold, at a fraction of the price
S925 Sterling Silver
Our silver pieces are made with nickel-free sterling silver (also known as S925) and enhanced with coating for added shine. Sterling silver is an alloy made of 92.5% pure silver and 7.5% copper. It’s a lightweight metal that is highly durable and designed for everyday wear.
Why Sterling Silver?
- Tarnish Resistant – Durable and easily polished to regain shine
- Kind to Your Skin – Hypoallergenic, suitable for sensitive skin types
- Accessible – Sterling silver resembles white gold, at a fraction of the price
Cubic Zirconias
Cubic zirconia (CZ) is a popular choice in jewelry due to its affordability and versatility. Cubic zirconia can be cut into any shape and scores 8–8.5 on the Mohs scale. However, because cubic zirconia is less hard compared to moissanites and diamonds, it is more prone to scratching and losing its initial brilliance and clarity over time.
Moissanites
Moissanites score 9.25 on the Mohs scale, making it the second hardest gemstone used in jewelry after diamonds. This makes moissanites extremely durable and suitable for daily wear.
