Here's an example of a necklace that took me maybe 40 minutes to create, almost from scratch. There are some imperfections with the sizing / spacing, but those are all fixable within the notecard program (I was just too lazy to do it right). And afterwards, I was able to custom-fit them to three different avatars, within a few minutes.
The centerpiece was made separately, by using the BRACELET setting to rez the sapphires in a simple circle. I then linked the ring of sapphires with a large diamond, and made that a separate link, called "diamondcenter."
The notecard program looks like this:
ODDLINKS
LINKTYPE FLAT
LINK diamondcenter~13.5~<180,>~<-0.00003, 0.00011, 0.03778>
LINK diamond 1.9mm~1.861572~<180,>~<-0.00002, -0.00005, 0.00946>
LINK diamond 5.7mm~5.699158~<180,>~<0.00001,>
LINK round sapphire~1.861572~<180,>~<-0.00002, -0.00005, 0.00946>
LINK diamond 5.7mm~5.699158~<180,>~<0.00001,>

ENDREPEAT

Translated, line-by-line, the notecard program reads:
- use an odd number of links, so that the center piece will be centered
- rez the center piece, then a 1.9 mm diamond, then a 5.7 mm diamond, then a sapphire, then another 5.7 mm diamond
- then, repeat the following, until we're almost at the side of the necklace, 80 degrees from the front
- sapphire
- 1.9 mm diamond
- then, rez a silver tube
- since we're now at the end of the notecard, just finish up the necklace using the silver tube
But the point of this exercise wasn't to generate a perfected necklace, but just to illustrate that it took less than an hour of time to generate a fairly decent necklace. And that once generated, it could be resized to custom-fit most any avatar.
