This is a natural flower amber (bursting amber) freeform bracelet. Core Material: Amber (mainly golden amber/golden honey amber) treated with an artificial "bursting" process, resulting in numerous flaky and flocculent red/gold bursting patterns inside, visually resembling "blooming petals," hence the name "flower amber." Color and Texture: Overall golden-orange to wine-red hues, high transparency; when light penetrates, the internal bursting patterns create a shimmering, iridescent effect. The surface is polished and rounded, with a warm luster. Bursting Process: Baltic amber naturally contains tiny air bubbles. Under high temperature and pressure, these bubbles are stretched into flaky and flocculent red/gold bursting patterns, which is the source of the "petal" texture you see. This is a high-quality Baltic bursting flower amber freeform bracelet. Natural Base: The prerequisite for "bursting" patterns is that it must be natural amber, thus retaining the physical properties of amber. The bursting patterns in natural amber are natural and irregular, making each bead unique. The total weight is approximately 11.9g, suitable for a wrist circumference of 14-16cm, with a bead width of approximately 11-12.5mm.
