Bagpuss, That's a real beauty! I have only seen a couple other picture of diamonds described as Swiss cut, but they don't look like the picture you posted.  The diamonds on the sides of the emerald is supposed to be Swiss cuts. More pictures can be found on this site -- Nelson Rarities Rings I'm hoping Oldminer will found this thread and give us his opinion.

Bagpuss, Is that your ring? It's beautiful. If not, where is that picture from? I'm in the market for an old cut and that one is just lovely. Any stats beyond carat weight? Thanks!!

I found this quote: "Swiss Cut is halfway between a brilliant and an eight cut, with 34 facets in total." win "... (Corporations) have all the benefits of voters, without the guidance of a conscience. ... Corporations they will bring this country down." |

This is from some guy who did his thesis or dissertation on diamonds ... Table Cut: It is a rather simple cut: an octahedron with one vertex truncated to expose a square face, or a table. Introduced in the early 15th C until mid 17th C, though it was found in Indian and other native jewelry. This is probably the simplest cut, which is not too surprising in the view that diamonds are pretty much impossible to cut and polish with tools available at that time period. Rose Cut: AKA the Crowned Rose cut, Full Holland cut, or the Dutch cut. Looks like a hemisphere, with a flat base. It has polished flat facets in a regular pattern symmetric about the axis. It could be as few as 3 facets, as many as 24. Senaille Cut: Irregularly faceted and shaped Rose cut. Pichere: Irregularly shaped chips of diamond. Peruzzi Cut: The first cut that has recognizable facets. Named after Vincenzio Peruzzi, who was credit for inventing this cut around 1700. The 56 facets are arranged in a very similar manner as the modern round cut, but stretched over a differently shaped stone. It is square, or almost square (instead of round), the table is small, the culet is large, and has higher crown and deeper pavilion. Looks like halfway between a table cut and round cut. Old Mine Cut: You may actually run across this in old jewelry. It is similar like Peruzzi, but the corners are rounded. Again it has high crown, deep pavilion, small table compared to the round cut. Looks like an intermediate between Peruzzi and brilliant. Cushion Cut: same as the Old Mine Cut, except that is used for colored stones as opposed to diamonds. Single Cut: AKA the Eight Cut. Used for stones that too small (< 5 pts) to be cut into a stone with more facets. It is approximately the same shape as the brilliant, ignoring the facets: it is round, has similar crown height, pavilion depth, table size, small (or no) culet. But the crown is composed of eight trapezoidal facets, one side of which forms an edge with the table, the opposite edge is on the girdle, and the two remaining opposite sides of the equal length form edges with adjacent identical crown facets. The pavilion facets are just acute isosceles triangles, with bases on the girdle, and the opposite vertices on the culet. This makes the total of 16 facets plus a table. Swiss Cut: Used for smaller stones as well. It is halfway between the brilliant cut and the single cut. Again, similar dimensions to the modern cut. The crown has 8 isosceles triangular facets which have bases on the girdle and apices that form the octagon of the table, and has another 8 isosceles triangles which have bases on the table to form edges of the table's octagon and apices on the girdle. On the other side of the girdle are eight isosceles triangular facets, which pretty much share the base with the former crown triangular facets. The rest of the pavilion is taken up by eight rhomboidal facets, whose two adjacent sides form an edge with the neighboring identical facets and with the corners between these two edges forming the culet; the other adjacent sides form an edge with neighboring aforementioned triangular facets, with the corner between the two sides on the girdle. That makes it 32 facets, a culet, and a table. Native Cut: a nice way of saying an irregularly cut brilliant cut. win "...
