Recent discussion of medals with precious stones brought to mind the ANA convention medalsissued in 1966. The convention badge had a name badge and hanging red, white and blue ribbonand hanging bronze medal.

The building shown on the badge is a representation of the Chicago Water Tower. The white dotin the field near the upper left is a small diamond chip as the 1966 convention was the 75-yeardiamond jubilee for the ANA.

Less frequently seen is the exhibitor medal. It features the convention badge with a reproductionat the top. The black dot on the badge near the left top is a hole that once contained a diamondchip. I don't know the story but I can guess that a previous owner removed the diamond thinkingit could be sold at a great price.

I suspect that owner found the diamond to be worthless and the medal without the diamond wasworth-less. The missing diamond could be replaced at little cost but I never made the effort.

During the time of high gold prices around 2010, I was a gold jewelry and scrap buyer for GroveCoin in Woodbury, Minnesota. My boss would handle the purchase of any large diamonds of ahalf carat or larger. Smaller stones that came with gold jewelry were inconsequential.

A customer would come in with a plastic bag and a mixed lot of chains, rings, tie tacks and cufflinks. I would sort the items, weigh 10K, 14K and 18K separately and make an offer that wasusually accepted. I explained that my offer was based on gold weight with no added value forany stones. Occasionally a customer would ask to have a diamond removed and we would give itback to them. The scrap went into a tub to be melted.

I heard from a customer who gave her wedding diamond to her young daughter who played withit in her sandbox.

It might take several months to accumulate enough scrap for a melt. A batch might include holedor damaged U. S. gold coins, odd denomination world gold coins and occasional gold medals.We tried to have the lot average 14K or higher.

The scrap would be melted, a bar poured and stones would float to the top and be imbedded in alayer of slag. As a service, the smelter would separate off the stones and colored glass and returnthose to us.

There was also a process to frost the stones with hydrofluoric acid (HF) to separate diamondsfrom cubic zirconium (CZ). We had glass vials with scrap diamonds sitting around for yearsbefore they would be sold.

The industry term for scrap diamonds is melee. It is measured in points with 100 points to a caratand five carats to a gram. There are melee buyers who travel the country and buy fromaccumulators like us. I recall a deal where we sold for $1 a point of $100 per carat. Yes, thatstuff has a value, but it takes hundreds of transactions over a period of years to accumulateenough for a sale.

We were left with a glass jar with hundreds of colored stones and bits of colored glass. Theremight be a market for that somewhere, but we never found that market.

A seller with a single small diamond removed from a medal is not going to find a market to sellthat stone.
