87.5% pure · 21/24 · hallmarked 87521K is 87.5% gold, stamped 875, and it is the Middle East's own standard — uncommon in Europe or America, dominant from Cairo to Kuwait. The extra alloy over 22K buys enough hardness for daily wear while keeping the warm yellow that reads as gold rather than as pale metal.
It is the karat most Arab jewellers quote first, and the one most likely to be in the window with a per-gram price on a card. If you are comparing shops in this region, comparing their 21K gram price is the closest thing to a like-for-like test, because nearly all of them carry it.
Because it is the regional default, it also has the deepest resale market here: a 21K piece sold back in Amman, Riyadh or Cairo is priced against a number the shop quotes every morning, with no need to convert from a standard the local trade does not use.
The dominant retail karat in Indonesia is 22K, so 21K is usually a deliberate choice here — bought for what it does better, not because it is what the shop happened to have.

Indonesia gold market
Indonesia's retail gold market centres on 22K gold (91.7% pure), quoted locally per gram in IDR. As a free-floating currency, the IDR means prices also reflect daily IDR/USD exchange-rate moves. Indonesian jewellery spans 22K to 24K, and cast bars from state miner Antam are the benchmark investment product.
