With years of experience, we handle items of assured quality. Each piece is crafted with care. Even those new to jewelry can purchase with confidence, knowing they have made a wise choice. ---------------------------------------- ▷*Maintenance Method* Jewelry can become soiled with sebum, sweat, and oils after use. If left unaddressed, this can diminish the jewelry's natural brilliance. After each use, gently wipe away any dirt with a soft cloth before storing. Oily substances and alcohol found in cosmetics, hairspray, and perfumes are detrimental to jewelry. Removing or putting on clothing while wearing jewelry can lead to damage or loss. Please handle with utmost care. ▷*Storage Method* Gemstones vary in hardness, from very hard materials like diamonds to softer ones like pearls. Storing hard and soft gemstones together can cause scratches due to friction. When storing, use small pouches or dividers in a jewelry box to ensure each piece is kept separately and prevented from clinking against others. ▷*Situations Requiring Caution* It is best to remove jewelry when it may get wet, such as during bathing. Soaps and water scale can tarnish the brilliance of gemstones. Furthermore, jewelry is susceptible to chlorine and sulfur, which can cause discoloration of gemstones and metal. Please be mindful of this.
