Can you melt two diamonds together to make a bigger diamond?

I have two diamond rings, one size 1/2 ct and the other size 1/3 ct and I was wondering if the two diamonds could be melted together to make a bigger diamond?|||no|||No, you cannot fuse two diamonds. Diamonds *can* melt, just as everything can melt. But what almost always happens is that they *burn* releasing some carbon dioxide, but mostly just leaving behind a pile of carbon (which is how it was discovered that diamond is just a pretty lump of carbon).





This goes pretty well for most minerals other than naturals like gold, silver, and copper... all of which are native metals.|||Yes and no. It's possible to melt but you could not really fuse them together. The temperature required to do melt a diamond is more than 3500 degrees Celsius anyway. So....no idea how an ordinary consumer would get access to that kind of heat source.|||Not in Nature, but like with most household items, Crazy Glue and Ductape will fix most things!
