This is a wonderful pair of stones:2 CZ but not like other cz…On the market you can buy cz in different quality: A, AA, AAA, AAAA, AAAAA…and so on.. But above all there is one cz which is much beautiful than all others.. The “HEARTS AND ARROWS” CZ. It is the cut that makes the quality. The cut is perfect, really perfect and when you put the cz in a special machine that calculate the perfection of a cut, you can see hearts and arrows, which is the only way to know if the cut is perfect…This is the best CZ in the world and when comparing with other cz , you can see right away the difference…We have the PINK"HEARTS AND ARROWS” cz in 5,75mm,6,75mm, 8mm…It does not exist in size bigger than 10mm.
