24K, as this is supposed to be pure gold, and 18K is about 75% pure. The more pure the gold alloy is, the higher the value.

The main difference between 24 karat gold and 10 karat gold is the purity. 24 karat gold is pure gold (99.9% gold) while 10 karat gold is only 41.7% gold with the rest being alloyed with other metals for strength and durability. As a result, 24 karat gold is softer and more prone to scratches and bends compared to 10 karat gold.
10K Gold Italy means that the object, and I am sssuming it is a piece of Jewelry was made in Italy and that the fineness of the gold is 10 Karat. The fineness of Gold is determined by Karat. Fine Gold is pure GOLD and is 24 Karat, there are 24 units to a Karat, therefore a 10 Karat piece is less than half pure gold., or 5/12 Gold. The gold is mixed with other metals called alloys.
24 karat gold is 100% gold, 18 karat gold is 75% gold, 14 karat gold is 58.3% gold, and 10 karat gold is 41.7% gold. The remaining percentage in each karat weight consists of other metals like silver, copper, and zinc, which are added to improve the durability and color of the gold.

10 karat gold is a combination of gold and other metals that is actually less than half gold. Because of that the value of 10 Karat gold is going to be much less than 'bullion' gold, probably as little as 25% of bullion gold because of the effort necessary to reclaim for pure gold from the mixture. I say that ten carrot gold is worth 60 to 1oo dollars
