Heart puffy heart, Gold stone brown (synth.), 4.5 cm

The worldwide spread of the heart symbol through art, playing cards and religious heart worship has made it probably the most popular non-geometric symbol. To this day, the heart is considered the symbol of love and partnership.

Gold stone is not a naturally grown mineral, but synthetically produced Glass.
The fascinating process for producing Gold stone was discovered around 1626 by the Venetian glassmaking family Miotto: initially colorless glass becomes sparkling, colored decorative glass that can be cut and engraved by adding metal compounds.

In the absence of air and through very slow cooling, fine copper crystals can form in the melt, which later trigger the sparkle.

Gold sand stone is also known as Gold sand stone and aventurine glass. This is derived from the Italian term "per avventura" (by chance) and refers to the unpredictable distribution of the crystals.
