This is an amazing ring because it is heavy meaning there's a lot of 18K gold used in its constuction.  The settings is in 18K white gold and the buckle is 18K yellow gold.  There are 30 princess cut SI clarity and G color (better than HI) diamonds for a total of one carat.  The diamonds extend 3/4 inch around the ring.  The ring has a modified square shape on the outer edge.  It is truly unique and for a special person.  This stunning ring is size 6 but can be sized up or down.
