Donuts can be integrated into jewelry in many different ways. Mini donuts, for example, are ideal for incorporating into necklaces or placing in hoop earrings. The large donuts look eye-catching on a longer ribbon and can also be used in a variety of other ways with the help of a Donut Holder.
Gold river is not a naturally grown mineral, but synthetically produced Glass.
The fascinating process for producing gold river was discovered around 1626 by the Venetian glassmaking family Miotto: initially colorless glass is transformed into sparkling, colored jewelry glass by adding metal compounds, which can be cut and engraved.
In the absence of air and through very slow cooling, fine copper crystals can form in the melt, which later trigger the sparkle.
Gold river is also known as gold sandstone and aventurine glass. This is derived from the Italian term "per avventura" (by chance) and refers to the unpredictable distribution of the crystals.
