Hello! I'm not sure if I'm posting in the right area or even forums, but I am searching for an engagement ring. I'd like it to be very unique and I am searching for either a ring with a star cut (rising star or anything star-shaped) diamond or a loose star cut diamond. So far I've only found 2 star cut diamonds (on eBay) and they were red. Where can I find this rarity? Guide me please!

Hi Zoriah,

A single stone that is a star shape is going to be a tough nut to crack. The only star shapes that I have seen are numerous diamonds that have been cut to fit together in order to make the shape of a star. They are very uniqu and quite spectacular. I would start by calling some local jewelers in your area. See if you can shake anything from the tree that way. Good Luck.

Wow! I've never heard of a star cut diamond. What is it??? Is it cut like a star?

The ones I have seen are 5 individually cut diamonds that when placed together form a star. They are typically set in earrings or pendants.

They are made but very expensive due to the weight loss of the rough to cut a star diamond.


Rising Star Cut Diamond
Print Article

The Rising Star is a patented cut of Fancoldi Registered Trust Ltd.



PHYSICAL CHARACTERISTICS AND CUTTING ISSUES
The Rising Star was granted a design patent with the U.S. Patent Office in 1992 based on the new technique of achieving its cut; subsequent patents were registered in all diamond polishing countries. It was developed in Liechtenstein and is now cut in Israel. It is the first fancy-cut diamond to fully resemble a five-pointed star. The Rising Star is a full-depth stone with 56 brilliant facets (a round diamond has 57). Its diameter, depth and proportions are equal to that of a round diamond, taking into consideration the "missing" diamond pieces between the points. The cut is manufactured to be strong and durable.

It takes about three-and-a-half times as long to manufacture the Rising Star as it does to produce more traditionally shaped diamonds. The cutting and polishing of this cut is highly complex and risky. Prefaceting shaping is done with custom-designed, high-technology equipment. Polishing is done in every direction of the stone, as opposed to the polishing of a more traditional cut, which is done in two basic directions. Each polisher is trained to do only his or her aspect of the process. That is, the cutters who polish the bottom facets are not trained to polish between the points, etc.

Piqued rough is not used for the Rising Star to prevent breakage, cracking or exploding on the polishing wheel. Fine octahedron rough is used. The Rising Star is not cut for weight retention but for maximum brilliance and symmetry. About 75 to 80 percent of the rough is lost to produce this cut. Rising Stars are available in sizes from 3 to 20 mm and in all colors, including fancy colors, and clarities.

Nice picture Jan. I for one would not want to set that!

Here's another one of those oddball shapes. Horsehead diamonds??? Go figure!

[jan]

Yes and the wierd thing is that you need a 5 prong head. Hard to find. The 4 or 6 prong won't work.
