February 2019 Newsletter: Heart Shaped Gemstones


There are few gifts as romantic as a fine piece of jewelry, and few gems as romantic as a heart shaped stone. With Valentine's Day approaching, let's look at what makes heart shaped gems so special.

Heart shapes are actually one of the rarest of the fancy cuts and are quite hard to find. Pear shapes are much more common, since pears can be attractive in different proportions, from a fat pear to a long elegant teardrop. But heart shaped gems are only attractive and well-formed when the proportions (height:width) are in the range of 1:1 to 1:1.2.

Heart shaped gems are so distinctive that there is a specialized vocabulary to describe the parts of the shape. The cleft is the V-shaped area between the two rounded ends or lobes of the heart. The slightly curved center where it widens on each side below the lobes is called the belly. As it begins to taper toward the bottom of the heart, the area between the belly and the point is called the wing, 

Parts of a Heart Shape Gem

A well-cut heart shaped gem will display balanced proportions and symmetry, with lobes that match in size and shape and curve smoothly to the point. The cleft can vary in depth, but should display a well-defined V shape.

Give your heart to your beloved this Valentine’s Day, and celebrate the day with a heart shaped gem. It will be a gift you’ll both treasure for years to come. Happy Valentine’s Day!

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

Could you explain the clarity grade "eye clean"? When is a gem considered eye clean? RM, USA

Eye clean is considered to be the key clarity grade in the gem trade, since its the minimum standard for a fine gem. A gemstone is considered to be eye clean when no inclusions are visible to the naked eye from a normal viewing distance (about 12 inches), when the gem is viewed looking down through the table.

Since most natural gemstones have some inclusions, you may be able to detect inclusions in an eye clean gem, either by inspecting the gem under a loupe or by examining the gem through the pavilion. The important thing about the designation eye clean is that it indicates that any natural inclusions in the gem will not be visible or detract from the beauty of the gem when set in jewelry.



All the best in gems,
