Surgical Stainless Steel 316L Gold Coating Stone: Strawberry Quartz ◎ Natural Stone: Some stones may have cracks, chips, or inclusions. There are individual differences in size, shape, and color. Please enjoy them as the natural charm of the stone. Some stones may change color in sunlight or are sensitive to water. After using them in accessories, it is recommended to clean them with a soft cloth, store them in a zip-top bag, and avoid sunlight. I hope you will cherish each and every one of them as their own unique personality. ( ⁎ᵕᴗᵕ⁎ )❤
