Because me and the recipient of this pendant were quite pleased with it. Granted, it's not Mikimoto in quality...or price. However, the coloration and luster is even, there are no blemishes discernible to the naked eye,  the shape is good and the setting seems solid.  Essentially, the item I received was entirely consistent with the product page description here and in most respects exceeded my expectations.

The pendant may be a little weighty for the delicate white gold plated sterling silver chain so on occasion it has to be repositioned but at the risk of salaciousness that only draws more attention to the abundant cleavage the real pearl of my eye, not that that area needed any further assistance. The chain clasp tends to stick somewhat and I don't exclude replacement of the 18" chain in the future but that possibility doesn't diminish the value for me.

The pendant is attractively packaged in a tasteful velvet lined box. The vendor also provided a cloth storage pouch and a pearl care instruction card along with a certificate of authenticity. I only kick myself for not having the confidence to order matching earrings at the same time.
