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 center point, 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.

SweetHeart - Cutting Remarks

Here is a "SweetHeart" of a heart with excellent optical performance that's not hard to cut. This is a very suitable design for a novice wanting to cut his or her first heart as well as pro cutters. Since designing "SweetHeart" I've cut and sold over a dozen of them to local jewelers and wholesale clients who are incorporating them in Valentine's Day gifts, which warms my heart as well because it is a fast design to cut.

Exercise some care in lining up the centerpoint of the pavilion with the axis of the dop, if you are a little off center, just transfer (after cutting of course) to a V-dop instead of a cone 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.

Here is a cutting tip from Donald Specht, I thought was a good idea... (thanks for the tip Don)

I cut one in a (synthetic) spinel and found a very easy way to make sure all the pavillion facets meet at the center point of the dop. I first cut all of them (P1-P7) at the steepest angle (38.6). This is not a temporary center point - it is the actual CP and it is exactly centered on the dop. It doesn't waste any material either. I then recut the facets using the correct angles. I find it very easy to see the recutting and to bring it up exactly to the tip of the CP. Works for me.
