this is a 18k rose gold vermiel adjustable size 5-10.5 natural earth mined 2.3ct. Columbian emerald ring brand new. thus is another ring designed and hand picked by us . this ring really shows off the solitair 2.3ct. natural Columbian emerald as it is the only stone and it truly pops in the rose gold setting. I really have never been a fan of rose gold but when we had the stone put next to this setting it just screamed yes please and what a marriage it made this ring is just stunning and the perfect color of this hand picked stone seems to look even better set in the rose gold so we had to do it. we are doing this to bring you some of the nicest stones usually out of price range from average person at a price many can afford. this ring comes with the certificate from the laboratory showing authenticity and pedigree of the stone thanks to my great childhood friend JON thank you brother. we bought so mantle stones we got them at Un worldy prices. many more pieces to come. also thank you Mike for the settings and for setting the stones for us!! remember anything bought from now till new years gets a free gift of our choice at least the same price of what is purchased and they will be top end jewelery not unreliable stuff that we couldn't sell.
