Rose Tear 120a-96 Cutting Notes

This meetpoint design for a rose cut tear incorporates identical plan views for both hemispheres. Begin by cutting a 12-sided cylindrical preform. The height of the preformed cylinder must be at least 1.58 times greater than its maximum width for you to have enough material when you get to the course 5 and e (pole) facets. When you cut the course 1 facets for the A hemisphere, create a level 'girdle' (equator) line dividing the height of cylinder proportionately, allowing 2.15 times more for the z dimension of the B hemisphere as the A hemisphere.

Transfer when you've finished the first hemisphere, and repeat the course a-e sequence on the second hemisphere.

If you cut a Rose Tear 120a-96 of your own, be sure and let me know what you've cut and how you made out.

Shown at left is a caged Rose Tear pendant cut from CZ by George Ellis. George reports "Getting the length to width is important from the start. I missed it a little and was about 2mm too short. I just added an extra set of facets on the tip along the ridge lines to the point to get rid of the slight stub. George's Rose Tear weighs approximately 58 carats and is just under an inch in length.

New faceter, so everyone gets rocks for Christmas... ;)"



Depicted below is a 34.4 carat Rose Tear cut by Jim Foster (a.k.a. Swarfmaster). It was cut from garden glass having particular appeal to visitors at Lotusland, a botanic garden in Santa Barbara, CA., because of glass displayed in the garden. Jim reports it cuts a remarkably bright stone and he also sells earrings and pendants faceted from garden glass at Lotusland. Nice work Jim!

Shown at left is a caged Rose Tear pendant cut from CZ by Dewayne Glover. Dewayne's Rose Tear weighs 25 carats and is 0.3 x 16.5 mm in size. Dewayne reports "As with the other cutter I was a little short, but I dropped the last tier to 40 and was just fine I think 1.58 isn't generous enough for the L/W my next attempt will be 1.75.

I managed to cut all the tiers without any over or undercuts. However the meet between the hemispheres had me concerned since I didn't have a girdle to rely on. Turns out my fears where unfounded it turned out brilliant; folks just need to sneak up on it and watch the cheater to keep the meet level."
