A bit of a jewellery question but chemistry related. I want to encase a synthetic ruby (corundum, Al2O3) in silver by melting the silver around it. Either in a furnace or by casting. The MP of silver is 960 °C.
The ruby will be facteded and polished. Now, in theory the ruby should be unharmed given that its MP is double that of the silver and is much harder. However, would there be any damage to its optical properties?
