While reviewing my references for ideas and approaches to heart shaped cuts, I noticed a marked scarcity of Barion hearts. Due to their single fold symmetry, hearts can be tedious and time consuming to cut. A Barion heart offers a number of advantages over more conventional heart designs, not the least of which are the reduction of elevation angle changes required to cut the pavilion, and increased optical performance.

'B' Still My Heart - Cutting Remarks

Shown at left is the prototype 'B' Still My Heart, a 16mm stone cut from a piece of pale, pinkish Brazilian Ametrine.

I have had a lot of good feedback from the "SweetHeart" cut and quite a few people asked me for a Barion heart. Here it is... "B Still My Heart" design is based on a round pavilion. The L/W is 1.0 for all practical purposes. Basically you cut to center point and then shape it to a heart. Because it employs an essentially round pavilion, the light return is outstanding for a Quartz heart. This also cuts well in Topaz and Tourmaline with no changes. I recommend a large light to medium colored stone - aim for a target size of 14 mm or larger.

The under girdle "cheeks" formed by the barion facets P12-19 are evident in the edge-on view of 'B' Still at right.

If you cut this in light material, don't be afraid to tangent ratio and raise the crown angles some if you want to chase dispersion. This design has plenty of brightness to trade off against increased dispersion when cut in light materials. If your material is darker, the high light return of "B Still" will be employed to maximum advantage and effect. I'll be on the lookout during the upcoming Tucson show for some primo rhodolite for some Garnet "B Stills" for local jewelers and wholesale customers.

Enjoy cutting your "B Still My Heart"... 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.
