Saudi gold and Italy gold are marketing terms that have been used for generations and accepted by Filipinos as if there actually is a difference. But if you think about it, you’ll never actually hear international brands claiming their gold is “Saudi” or “Italy” or from anywhere else for that matter, and it's because GOLD IS GOLD. It’s only here in the Philippines that we differentiate it as if it’s accepted globally, probably because there are a lot of OFWs working there and “Saudi” became a name or quality of some sort for gold standards.
Quality will depend on the kind of alloy/metal mixed in the gold to make it 18k or 14k etc. You have to trust your jeweler that he or she is providing you with a good mix so that your pieces don’t tarnish over time. 24k is 100% gold, 18k is 75% gold, 14k is 58.5% gold - this is how you properly measure quality. We dare you to ask Cartier or Tiffany&Co. if the gold they use is Saudi or Italy and we guarantee they'll look at you perplexed.
Others may claim that different countries have different shades of gold. Again, color outcome is dependent on the kind of metal you mix into the gold, not the country.
A lot of jewelers can take advantage of consumers with fancy terms that have no backup explanations. PLEASE do your due diligence with research when it comes to gold and diamonds to help in making Filipino buyers more educated in the jewelry industry.

BUYERS NEED TO BE JUST AS EDUCATED AS THE JEWELER
