This 51.72 carat round brilliant-cut diamond is quite exceptional. When it comes to stones of significant size, diamond cutters will generally try to keep the maximum weight from the rough.

Here, however, the master craftsmen who cut the stones has chosen a round brilliant cut, which show off the diamond's exceptional physical characteristics to maximum effect. Find out more here .

What makes a diamond pink?

Luscious and rare, this Fancy Vivid Purplish Pink diamond is so exceptionally saturated it displays mysterious flashes of red.
