LOT 1648 - MATCHING PAIR OF PENDANT EARRINGS ENLARGED
LOT 1648 – MATCHING PAIR OF PENDANT EARRINGS ENLARGED

The matching pair of pendant earrings are each set with a cultured pearl, with white body color and rose overtone, and excellent luster, orient and surface quality. The dimensions of the two pearls are 14.00 x 13.69 mm and 13.80 x 13.90 mm.
Calculating the variation in diameter of the two pearls, we can decide whether the pearls are spherical, near-spherical or button-shaped.
1. Variation in diameter = (1 – shortest diameter/longest diameter) x 100
= (1 – 13.69/14.00) x 100 %
= (1 – 0.978) x 100
= 0.022 x 100
= 2.2 %
2. Variation in diameter = (1 – shortest diameter/longest diameter) x 100
= (1 – 13.80/13.90) x 100 %
= (1 – 0.993) x 100
= 0.007 x 100
= 0.7 %
Variation in diameter of perfectly spherical pearls = 0% to 2%
Variation in diameter of near-spherical pearls = 3% to 19%
Variation in diameter of button-shaped pearls > 20%
Variation in diameter of the two pearls are 2.2% and 0.7% . The first pearl has a variation in diameter slightly above 2% but still less than 3%. Hence, it can still be considered as a spherical pearl. The second pearl has a variation in diameter of 0.7% falling within the range of 0% to 2%, and hence undoubtedly a spherical pearl.
Thus the two pearls in the pair of pendant earrings are both spherical pearls.
The circular surmount of the pendant earrings has a circular-cut diamond in the center from which radiates several baguette-cut diamonds and a layer of small circular-cut diamonds bordering the surmount.
