Hello Valeria,
the thread indicated is about the Regente.
The PeLLegrina is not the PeRegrina which is said to mean “The Pilgrim"
and is a large pear-shaped white pearl of 203.84 grains The pearl was purchased in 1969 for $37,000 by actor Richard Burton for his wife, Elizabeth Taylor, who still owns it.
While the PeLLegrina is 111.5 grains in weight, perfectly spherical
But none picture can be found
I just applied to Christies who sold it in 1987
Meanwhile if someone knows more, I am still interested
Thanks in adavannce
