Frequently Asked Questions about Buying Gold Granules

Do you sell these granules by the gram?

Yes, the purchase of our gold granules is done per gram. You can select the exact amount of gold to melt for your jewelry.

What is the price of this gold to melt?

The price of 750 gold per gram  is directly linked to the official metal price. As a raw material, it is the most direct price for 18k gold you can find, before the cost of "shaping" (the jewelry manufacturing work).

Can I use these granules to create rose or white gold?

No, this is an 18k yellow gold alloy for creation, already prepared. Trying to create your own gold alloy by adding other metals is a complex operation that would alter the 750‰ fineness and is not recommended without metallurgical expertise.

Are these granules easy to use for gold casting?

Yes, absolutely. The quality of our grain is specially studied for gold casting for jewelry. Its purity and shape ensure homogeneous melting, making it ideal for beginners as well as professionals seeking consistent results.
