  • Semi-precious gemstones include but are not limited to topaz, amethyst, garnet, peridot, citrine.

How do I know if the gemstone jewelry that I bought is a natural gemstone instead of synthetic one?

Authenticity of natural gemstones are regulated and certified by GIA (Gemological Institute of America) or IGI (International Gemological Institute). However, in jewelry commerce practice, not every piece of natural gemstone other than diamond comes with certificates.

Semi-precious natural gemstones include but are not limited to topaz, amethyst, garnet, peridot, citrine, do not normally come with certificates, so it is important to buy from reputable brands or retailers.
