These gemstones are made from natural minerals, so it’s normal for them to have tiny imperfections. Cutting and polishing can also lead to slight size variations, especially between different batches.

Typically, bead sizes vary within 0.2mm to 0.75mm of the stated size, and bead hole sizes may differ by up to 0.2mm. For example, an 8mm bead strand may include beads ranging from 7.8mm to 8.75mm, with some beads measuring 8mm, 8.2mm, or 8.5mm. Similarly, a bead hole listed as 1mm may actually range from 0.8mm to 1.2mm. These small differences are generally not noticeable to the naked eye

Dyed: Gemstones are treated with color-enhancing substances, like dyes or colored oils, to improve or change their color. This method is often used for Dyed Jade.

Dyed & Heated: A combination of dyeing and heating is used to enhance or alter a gemstone’s color. Common examples include Red Agate, Black Agate, and Red Tiger Eye.

Electroplated: A thin metallic coating is applied to the gemstone's surface to change its color or add a shiny luster. Examples include Electroplated Quartz Crystal and Electroplated Lava Rock.
