This Jadeite Jade Black & Green Ring & Necklace Set in Yellow Gold Plated features natural jade stones with a total carat weight of 147. The set includes a necklace and ring with square-shaped jade stones in black and green colors. The jewelry is handmade and signed by the maker, with a metal purity of 14k yellow gold plated sterling silver. This set is perfect for various occasions such as engagements, weddings, anniversaries, birthdays, and more, offering a touch of beauty, luck, and fairytale fantasy with its retro theme.  Size up because the thick jade band causes a suction on finger.  I can weat the size 10 on my size 9 and 8 fingers comfortably.
