Rare antique/vintage ring! Big in size and made in solid yellow approx 18k gold (no hallmarks!) and set with big pastel blue natural sapphire of a big size -8.20Ct! this sapphire is pastel in color and it appears that it changes color very slightly from aqua blue to blue with lilac in the evening!!8-9th photos to show how deep the stone (great as birthstone ring because the sapphire touches the skin/ being in contact with the skin while wearing on the inside!)! I was reading about properties of sapphires and found an interesting info: "The sapphire should be embedded or fixed in the gold or diamond in such a manner so that it touches the skin of its user to channelize its powers in the life of a human being." ? "it should be fixed in ring in such a way so that a part of stone touches the skin to circulate its positive energy in the life of a person." ? ? Please the last photo of the copy of the paperwork. this is lovely baypass older ring! it is rare in size and design! and sapphire is more of older cut, because the all of the faucets a little different and the stone is very thick(deep not shallow cut!). also the band is kind of very "rounded" at the back - I ve only seen these type of the bands in older rings mainly from England/Europe, so it us probably was made in that area! the size approx 6.8 USA weight of the ring is approx 7.4g also please see photo of a copy of the document - it will come together with the ring. the sapphire is so transparent you can see through! - please see photo next to a ruler- you can see 5 through the stone (even it is a deep cut!!) ? this ring is great as every day /engagement ring because of the design - it can be worn even with jeans, simple casual outfit as well as for a special occasions when combined with another (cocktail or evening) jewelry! also diamonds and sapphires the most durable stones so this is another reason for it to be a great everyday ring - because it is very durable for everyday wear!! also the gold was polished by professional jeweler (previous owner decided to do so not me - just want to mentioned) so the gold is very shiny and pretty as well. ? it can be sized up to 3 sizes if needed by a professional jeweler as band is thick and has enough gold to resize it up! comes in a ring case and can be gifted immediately! fast priority USA and International shipping and smoke free environment! please feel free to make an offer! ? thank you!
