This heart works well in tourmaline, topaz, peridot, garnet, spinel, sapphire, zircon… with no changes. It is easy to cut. Be sure when you cut to centerpoint, that it is centered on dop. 1-12cts. |

Shown above left is a 9.3 mm SweetHeart cut from rose Malaya garnet. It weighs 3.64 carats. At center is a 16mm, 7.9 ct SweetHeart cut from some lilac colored Brazilian amethyst. Above right is an 11.8 mm SweetHeart cut from some top Nigerian pink tourmaline. It weighs 5.76 carats. This design exhibits striking dispersion with the amethyst as well as tourmaline. All stones cut by Jeff Graham. |
Exercise some care in lining up the centerpoint of the pavilion with the axis of the dop. This design is so close to 1:1 in L/W that there is nothing unusual as far as dopping. The bottom all cuts to centerpoint, and establishes the girdle line. It is really a nice heart shape and reads well from a distance with lots of flash and dispersion. Because of the way I designed the pavilion, it can be cut in tourmaline, topaz, peridot, garnet, spinel, and sapphire with no changes.
Enjoy cutting your SweetHeart! Drop me an email to let me know your results and what you’ve cut, or feel free to inquire if you have any questions or need some help regarding this design – Jeff.
