With years of experience, we handle jewelry of assured quality. Each piece is crafted with care. Even those purchasing jewelry for the first time can do so with confidence, knowing they won't make a mistake and will be delighted with their purchase. ---------------------------------------- ▷*Maintenance Method* Jewelry can become soiled with sebum, sweat, and oils after use. If left unaddressed, this can diminish the jewelry's original brilliance. After each use, gently wipe away dirt with a soft cloth before storing. Oils and alcohol from cosmetics, hairspray, and perfume are detrimental to jewelry. Removing or putting on clothing while wearing jewelry can lead to damage or loss. Please handle with care. ▷*Storage Method* Gemstones vary greatly 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 keep each gemstone separate and prevent them from bumping into each other. ▷*Scenes Requiring Caution* It is best to remove jewelry when it may get wet, such as during bathing. Soaps and water stains can dull the brilliance of gemstones. Additionally, jewelry is susceptible to chlorine and sulfur, which can cause gemstones and metal to discolor, so please be aware.
