Yes, that would change the debate! And if it's stamped 18K, but only gold plated, it's a fraud.
I am a little bit surprised: this setting is especially customized for this pearl shape, and each flameball shape is different. But now, everything is profitable to be produced by low-paying workers.
Even a lot of luxury jewels, so much expensive, are made by poor hands payed with a handful of rice. It's a shame.
