Trying to find Cabochon cut diamond

I'm trying to find a cabochon cut diamond. Yes, I'm absolutely crazy, and nuts, and am planning on destroying a perfectly good diamond. Now, with that said.. hi! I'm looking desperately for a cabochon cut, I've looked online all over for them, but to no surprise.. can't really find anything. It's going to be for an engagement ring, my girlfriend loves the look (her mom has one). Any recommendations? advice? warnings? btw, I'm in Orange County - California if that helps.

Here's an example of what I am referring to "from eBay". http://cgi.ebay.com/0-74-Carat-Fancy-Green-Natural-Uncut-Rough-Diamonds_W0QQitemZ5038551650QQcategoryZ3824QQrdZ1QQcmdZViewItem Hope this helps.

Probably what you're looking for is a faceted dome shaped diamond with a flat bottom, called a "rose cut". These are made in larger sizes predominantly by Indian companies, and a few others. If you do a google search you'll probably come up with something. Rich, Independent GG Appraiser Sarasota Gemological Laboratory

I've only seen those words written together once in a jeweler's shop, and can't tell for sure if they weren't joking; think of a pair of oval droplets with slightly uneven surfaces - more like some rosecuts with lots of small, irregular facets onto them barely visible due to the small slopes between them. Edited to add: Garry says it allot better than I could why smooth domes are very unlikely. Speaking of indian diamonds: since most diamonds are cut there anyway, nothing would come as a major surprise. However, I wonder if you were not directed to look for something related although not quite well described by 'cabochon cut' - the barely polished diamonds in polki jewelry could possibly be called 'cabs' although the shapes are not often symmetrical. I am sure someone could find much finer examples, but hopefully this gives some idea. As long as they are clean (any flow shows without those facets), well polished and properly set (foil backed, usually), why not. Modernistic designs work just as naturally (IMO) as these studied rough ones. Anyway, such stones would look like drops of water Of course your choice is unusual, but I can surely sympathise with that! I would love to hear how the search goes!

Garry H (Cut Nut) Ideal Rock Total Posts: 11,583 Last Post: 11/24/2009 Member Since: 8/16/2000	Technically one of the most complex tasks on earth. I have seen a diamond sphere polished to prove it is possible. Diamond hardness varies across the 3 crystal faces - it goes from hard to soft on each of the 3 possible faces (4 times for 100 or cube,twice 101 dodecahedra and three times for 111 octahedra). I have a friend who makes the worlds most advanced diamond record stylus - they sell for up to $10k - and they have parabolic shaped diamond needles. So it is possible - but it will cost you far more than a normal facetd diamond.

Because it is hard to cut it looks badly polished and people assume it is a soft stone, since it looks abraded. Some cabochon cuts have micro-facetsthis has been done on some black diamonds, which have a less defined and more likely to be cubic structure (easier to polish). Close observation and you can see the eye visible micro-facets. Garry Holloway FGAA DipDT HCA and Ideal-scope developer http://www.ideal-scope.com and http://www.HollowayDiamonds.com.au
