At Koumian Jewellery, the authenticity and quality of our jewelery is a top priority. That's why we want to help you identify whether a piece of jewelry is indeed gold by offering you helpful tips and techniques.
Marks of Authenticity:
Stamp: Look for a stamp on the piece of jewelry that indicates the purity of the gold. Common seals are:
750 for 18 carat (75% gold)
585 for 14 carats (58.5% gold)
375 for 9 carats (37.5% gold)
the real gold.
