Blue Rainbow Tahitian Teardrop Pearl Pendant set in 18K YG w/ Bezel set Diamond

As with all of the pieces that I list with pearls, this design is from the collection of my mother who worked for Yonamine pearls in Tokyo Japan for many years.I inherited many stunning and eclectic pieces and this is one from the collection. Unless otherwise specified all color is natural and no artificial enhancements have been made to the pearls. This show-stopping pendant features a gorgeous natural color Tahitian pearl (~13mm wide × 16mm tall) with a rare blue color and rainbow luster/highlights.The bail for the pendant is solid 18 karat yellow gold and is stamped "18K" as well as "001" denoting the point weight for the diamond.The pendant weighs ~4.75 grams total with a full ~1 gram coming from the gold alone. It measures ~28mm(1 inch) from top to bottom. The bail is a curved tube shape and measures ~5mm at the opening.***Please Note***The listing is for the pendant ONLY. Any chains or other pieces of jewelry that might be used to display /showcase the pendant is not included with the listing.I also have other listings that would pair well with this pendant so please take a look if you have the time and feel free to ask any questions :)
