Heart necklace 
 
Necklace are small stones made off opal.
Heart is made of rock crystal 
 
Opal is a gem formed from silica-rich waters. It takes its name from the Sanskrit word Upala which means precious stone. Later, it would be called Opallios during Roman times. There are two kinds of Opal – the common opal and the precious opal. Opal meaning is amplification, hope, and purity.
 
Rock crystal may be said to be associated with new beginnings. It is the birthstone for April, when signs of spring begin to emerge, and the gemstone associated with Monday, the beginning of the work week. It is, perhaps, a harbinger of all things possible.
