Comments: Platinum is one of the rarest metals in the world.  It is more expensive than gold because only 160 tons of platinum are mined annually, as apposed to 1500 tons of gold. Also platinum is more dense than gold, so the same ring will weigh significantly more in platinum than gold (precious metals are priced by weight). 

The Old European Cut diamond is the standard round brilliant that was made between 1890 - 1930. As a predecessor to the modern brilliant-cut , the Old - European cut diamond strongly resembles the modern brilliant cut diamond and is very popular among antique and vintage jewelry collectors. 

The rose cut originated in the 1500s and was commonly used through the Georgian and Victorian eras. Like other antique cut diamond cuts, they were cut by hand and meant to glow under candlelight. The shape of the rough diamond influences the shape the diamond will be cut into.
