The heart is the second rarest shape seen in diamonds. Uncommon as it is, heart-cut diamonds are in soaring demand in wedding jewelry and engagement rings. Heart being the universal symbol of love finds a frontal place in wedding and engagement rings where a heart cut diamond makes a profound expression of love. But there was a time not long ago when only 1.6% of the diamonds certified by GIA was heart-cut. The number has gone up significantly since making it not so rare anymore, but to this day, heart shape remains to be one of the most uncommon shapes in diamonds.
A Quick Study of the Cut
The geometry of a heart cut is quite complex. When studied through a loupe, a diamond dressed in ideal heart cut reveals facets numbered between 53 and 58. The table depth of a heart-cut diamond should ideally be between 59 and 62.3%. The best cut heart shaped loose diamonds have no culet, although a very small culet is excusable. A tip for buyers, if you are thinking the ideal heart shape, look for internal measurements of 10 and 30% ratio from length to width. Watch out for heart-cuts that have a bow-tie effect, a flaw that results from a too shallow or too deep cut.
A Brief History
The introduction of heart shape in diamond cuts is as old as nearly 600 years. It was Galeazzo Maria Storza, the Duke of Milan and a certain NicodemoTranchedini di Pontremoli who founded the concept in 1463. The first known jewelry to have a heart-cut diamond on it is a gold ring which Mary, Queen of Scots presented to Elizabeth I of England in the 1560s. That perpetuated heart cut as the royal cut. Over the next centuries, heart cut diamonds made appearances here and there, popping up in some eras while fading totally in others until it swang back into trend in the 21st century.
Color Recommendations
The colors that look best in a heart cut are the warm tones that exist between grades G and H. The colorlessness that exists in diamonds between D and F do not have a significant impact in pronouncing the shape of heart shaped loose diamonds. That’s the reason why jewelers recommend picking diamonds from M, L, K and J for diamond cut.
In Jewelries
Heart shaped diamonds are widely used in jewelry like pendants, charms, bracelets, but most of all, they are used in engagement rings, where it has permanently acquired a central place.
