GIA Certified 18.95 Carat Internally Flawless Type II-A Heart-Cut Diamond Ring
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. Set in 18k white gold with an astonishing heart shape diamond sitting in the center. Flanked by 1.5 carats of bullet cut diamonds. All 20 carats shine bright enough to light a room, The diamond is an extraordinarily rare “Type II-A” diamond, which signifies a lack of nitrogen atoms in the diamond. They are known to be exceptionally colorless and are the purest and most valued types of diamonds. The diamond is classified by GIA to be a type II-A diamond with a “K” color and “IF” clarity. See GIA appendix letter and certificate details in the image slots. Center Stone Details: - Carat: 18.95 - TYPE IIA *see appendix - Clarity: Internally Flawless - Color: K - Cut: Heart-Brilliant - Measurements: 16.07 x 18.15 x 11.05 MM - Polish: Very Good - Symmetry: Very Good - Origin: Golconda ________________________________ Ring Details: - Type: Three Stone - Gross Weight: 9.10 Grams - Metal: 18K White Gold - Total Carat Weight: 20.46 CTTW - Ring Size: 7 (adjustable) ________________________________ Side Stone Details: - Cut: Bullet - Carat: 1.51 - Color: F-G - Clarity: VVS1 ________________________________ 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...
