By Gad & Co.
Located in Miami, FL
This 18.95 Carat, Internally Flawless Type II-A Heart-Shape Diamond is the archetype of luxury. It embodies the essence of “Miracles of Nature.” That such beauty can be found in the greatest depths of our Mother Earth is what inspires us all.

GIA Appendix Letter:
Scientists classify diamonds into two main "types" - type I and type II - based on the presence or absence of nitrogen which can replace carbon atoms in a diamond's atomic structure. These two diamond types can be distinguished on the basis of differences in their chemical and physical properties.
Type II diamonds contain little if any nitrogen and they are subdivided into two groups (lla and Ilb) both of which are quite rare (less than 2% of all gem diamonds).
According to the records of the GlA Laboratory, the 18.95 carat Heart Brilliant diamond described in the GIA Diamond Grading Report has been determined to be a type lla diamond...
