I attempt to accurately represent and describe cut stones and rough
as to appearance, size, origin and fully disclose any known
treatments in its description. Because you view the images on a
different monitor with different settings, color is particularly fickle
to represent, but I do my best.

Volume/W e3  =  0.214
Cutting Remarks  -  Cut and polish the crown in the order shown and you should always have an easy set of meets for
each facet!  Don't rough in the Table, C13 or C14 until all the other facets are polished.  This is an easy heart to cut.  The
crown facets are cut and polished with at most, only two meet points for each facet! Just pick a pink or red stone and start
cutting!  Perfect for garnet and tourmaline.  These angles work without changes from R.I. of 1.54 to 2.17.
