Sometimes, when we're buying diamonds, we buy them one at a time. There are other occasions, where we are offered a group of diamonds, also known as a parcel, in such a way that it makes sense for us to buy the whole group, or most of it.
Let's say the cutter buys a grouping of rough diamonds. He knows his cost for this group of diamonds. If he sells them as a group, it does not matter what any one single diamond is worth.
In many cases, the cutters themselves need to buy a grouping of diamonds, and the diamonds have wildly different values.
Maybe some have stronger colors than others.
Maybe some are clean, while others have black spots.
Maybe the diamonds are of different sizes.
Maybe some of them finish as better cut diamonds than others.
In many cases, the cutters themselves decide to send each Diamond to GIA,in an attempt to maximum profit off of the whole business.
So, buying parcels is an opportunity, in many cases. Like every opportunity, it has its hazards.
The parcel that is the subject of this contest seems to be pretty uniform in color.
We are also considering a second parcel of diamonds. The other one has a couple of very light diamonds, and a couple of darker stones.
There is an I1 diamond, and 2 more I2 diamonds. If we buy them as a group, we need to know how much each is worth, to make sure it makes sense to buy all.
There's also this unique cut...is unique good?
