I have a ring with two stones i dont know if they’re diamonds. Its a 18k ring weighs 4 grams.

Inside the ring theres like a square where it says 750.
Theres another square where it has .157 (PD or DD)

Does that mean Per Diamond? I thought it was Palladium but it already says 750 in a seperate box…


Hi Gabe,

The decimal could indicates total carat weight. There are rings that has a mixture of palladium and 18k gold.
