(most gemstones in America are glass or plastic fakes ) real gemstones are graded just like diamonds.
The Blue Topaz Gemstone for this ring is approximately 5ct and stone quality of VVSI-SI2 in either a Pear or Oval Cut.
The Ronaldo gemstone rings are in limited supply and are very hard to build.
The ring design is over 3000 years old and we wrap the shank for a very thick shank that you will not find very often.
Ronaldo recommends you use the rings that you have as a guide for the perfect fit, do not guess.
