The name comes from the term for the holiday at the same time as Christmas. My dictionary lists this as a legal spelling & I liked it. When I originally published this it was in December 1995 and under the name "hexbari2". Not a really catchy name. I liked the idea of giving this away as a holiday gift, it has a Star of David in it, and it was the right time of the year, so Hanuka it is!

This is one of my earlier, but more successful gem designs. I suggest this with higher RI material of lighter color. I've cut this mostly with sapphire and pink ruby, but I've also seen gems cut by others in tourmaline. They all were breathtaking. The gem is best cut under 12 mm. I've cut it as small as 4 mm, so size is not much of a problem. It is also a good beginners cut.

The only place you are likely to run into problems is with the culet c facets. Don't cut these all the way to the B facets. They cut very fast and you can finish the meetpoint up when polishing. If you don't it WILL overcut. Enjoy!
