Gold-filled has a much thicker coating layer of gold compared to gold plating, and the coating is adhered with heat and pressure, so there is almost no worry that the coating will peel off like gold plating. Therefore, you can use it for a long time. Also, it is said that allergic reactions to metals are less likely to occur. ❥Please refrain from purchasing if you are looking for perfection as it is handmade. ❥Please handle the natural stones gently. ❥As they are natural stones, there may be cracks, inclusions, and chips. ❥Even with the same stones, the shape and color will vary. ❥The price may fluctuate depending on the supplier, even if the same stones are used. ❥The actual color may differ from the color displayed on your device. ❥Each piece is made with care♡ I would be happy if you could find your favorite among jazz's works♡
