Where do Tiffany diamonds come from? Are they 'synthetic' diamonds (also known as HPHT or CVD diamonds which are made in laboratories), or are they still 'real' diamonds took from the ground? I know it's very rare these days to find 'real' pearls since you only see cultured pearls on the market, or they must be really really expensive. But I was wondering if it's the same story with diamonds nowadays.
