14K A Lifetime Gold That Continues to Shine

This alloy contains 58.5% pure gold. While not as common in Japan, it is widely appreciated worldwide for its ability to complement any skin tone. It offers high strength and doesn't easily deform or fade. With a higher pure gold content than 10K, it features a soft, delicate color tone that 18K cannot achieve, while maintaining excellent strength, resistance to deformation and discoloration. It's also less likely to cause metal allergies. All our 14K products are stamped with the industry-standard "14K" mark.

Silver925 Adding Brilliance to Everyday Life

925 Sterling Silver is a lightweight metal made with 92.5% pure silver. Highly durable, it's perfect for everyday wear. All products carry the industry-standard "925" stamp.

CZ diamond An Accessible First Choice Gemstone

With exceptional transparency and strong light reflection, CZ diamonds boast a beauty that's indistinguishable from real diamonds to the naked eye. Being synthetic stones, they lack the inclusions found in natural stones, offering a clear, high-purity brilliance.

COATING

As the final step in production, products are covered with two layers of "special protective film" using our proprietary technology. The first layer is quartz, applied to prevent metal oxidation. This is followed by a Lotus Effect layer that enhances dirt and water resistance. Inspired by lotus leaves, this coating provides water and oil repellency. Made from organic silicon compounds used in soft contacts, lenses, and baby bottles, the material has minimal allergy risks. These two special protective layers prevent jewelry corrosion while enhancing overall brilliance. The coating is available in two colors

Silver 925 is coated with a layer of 18K pure gold, featuring the characteristic depth and subdued golden color of 18K gold. With five layers of coating including our proprietary protective film, it offers excellent durability.

Silver 925 is coated with a layer of rhodium, a precious metal. Rhodium is extremely hard and resistant to scratches and wear, and its beautiful shine has earned it the name "platinum coating."

FOR EARRINGS

We ensure quality through patented technology1 obtained by our production factory. We have acquired ISO 9001 certification2 for managing the process of providing products and services to customers. We prioritize not only quality but also price and delivery time balance. We use production factories that have received certification for quality risk management.

Structure and Durability：
Existing clip-on earrings use spring force to press against the ear, which can cause pain and headaches. DAUGHTERSJEWELRY adopts a form that secures according to ear thickness, making it less likely to cause ear or head pain even with prolonged use. Unlike existing structures where even strong pressure can slip off due to improper fit, DAUGHTERSJEWELRY uses inversely tapered figure-eight shaped contact surfaces that hook onto the earlobe to prevent falling off. The metal parts have also passed a 2,000-cycle durability test*3 for opening and closing.

Wearing and Design：
Unlike conventional brands requiring adjustment during wear and frequent checking, these can be easily attached by simply pinching with one hand. Additionally, springs and metal parts are completely invisible when worn, making them look exactly like pierced earrings from any angle (360 degrees).
