The price of an amethyst bracelet mainly depends on four aspects:

Color: Naturally produced amethyst is beautiful because it contains iron, manganese and other minerals. The main colors of purple are lavender, purple-red, deep red, bright red, deep purple, blue-violet and other colors. Deep purple-red and bright red amethyst bracelets are the most expensive, while purples that are too light are more common. Within the same type of crystal, different parts of it have different textures and colors

. If it is a single color, the color must be uniform. If there are shades of light on the same crystal, the tone and texture must be beautiful and generous.

Material selection: For good amethyst raw materials, there should be no gas-liquid inclusions distributed in the form of star points, clouds and flocs. It is better if the raw materials are pure, smooth and crystal clear. Natural amethyst usually has natural ice cracks or white cloud impurities. Amethyst with gem value is produced in geodes of volcanic rock, pegmatite, limestone, and shale.

Technology: Bracelets are abrasive products. A well-made amethyst bracelet should be exquisite, which can not only fully display the external beauty of the amethyst bracelet, but also maximize its inner beauty, including Crystal clear and clever color. For bracelets and necklaces, check whether the holes are straight, whether the thickness of the holes is uniform, and whether there are any small cracks. The hole wall must be clear and transparent without "white marks".

Polishing: The quality of polishing directly affects the value of the amethyst bracelet. The crystal must be polished with emery during the processing process. Rough production will leave traces of friction on the surface of the amethyst. A good amethyst bracelet naturally has better transparency and luster, which is what we often call "fire head and foot".
