In order to calculate the total weight, you could weigh the gold and the stone separately, since the weight measurement formulas are different for each.
Carots for the diamond. Grams for the gold or silver.
You may be able to estimate the carat weight of the diamond given its physical measurements -- if you do not know it -- and deduct that weight from the gramme weight of the metal. Conversion to a standard weight measurement is required: your jeweler may be able to help you with this challenge.
Depends on how big the ring is
Every diamond is valued by its cut, clarity, colour and carat weight, which together with the price of the metal in the ring would total the cost of a ring -- regardless of the year.
A 2 carat diamond cushion cut ring would make a beautiful engagement ring. The price of such a ring would vary from jeweler to jeweler; however, one could expect to pay from around $450 upwards.
Your answer depends on how much was paid for the ring in 2002 and the quality of the diamond(s) set in the ring.
$60
A 4 carat diamond ring would be ridiculously expensive. In the $100K mark I would expect. If someone is showing you their 4 carat engagement ring, it is probably cubic zirconia.
A diamond ring without any certificate does not make sense because you don't have any proof of the diamond's reality.
The value of a diamond depends on its cut, its clarity, its colour and its carat weight. A local jeweler can give you the answer you want.

A local jeweler can answer your question, since no two 0.5 carat diamond rings are exactly alike.
