I forget what size...maybe around a 4ct? But from the pics I've seen here, they look real similar to the jubilee. Jonathan, what's the difference? In cut...not price . Thanks!!!

valeria101 Ideal Rock Total Posts: 14,048 Last Post: 4/30/2006 Member Since: 8/29/2003	The two cuts are really different models, the step cut crown of the lucida is quite far from the brilliant-like one of the regent, the table shape is different too (square for lucida, round for the regent)... The pavilion design is somewhat closer, but not too much - the Lucida design had lareger facets on the pavilion. The cut diamgram of the Regent is not relesed (as far as I know), but you may want to check the GemAdviser models at GOG. The Lucere is considered the closest by facet pattern. See below: Jonathan has posted Gem Advisor files of the Lucere some time ago. I could not find the post, but have the file, if you want it. With the Gem Adviser, you can line up the 3D models on your screen and have a rather good look. Ana "The greatest experts are only as good as the sum total of what they have seen." [Souren Melikian]

limey Cut Rock Total Posts: 264 Last Post: 7/14/2004 Member Since: 3/4/2004	Lucida has a step cut crown, the Jubilee has a more conventional crown and a pavilion similar to a round brilliant. The general look of the Jube is that of a well cut round H&A diamond but within a square. And it is unmistakably a square. I don't know how well the Lucida performas on the various light measurement technologies but the Jubilee performs as good as the best cut rounds. GOG also sells the Lucere which is similar to the Lucida but without the Tiffany tax. http://www.goodoldgold.com/lucere.htm

valeria101 Ideal Rock Total Posts: 14,048 Last Post: 4/30/2006 Member Since: 8/29/2003	But of course Tiffany would not need to demonstrate their diamonds are great I definitely like those step cut facets, whenever they appear. So I did pay some attention to these mixed cuts... Here's the impression: One Lucere produced the results for cut quality listed below. The other chart represents a Regent (bot from Jonathan, of course). It seems that the step cut crown works well for the Lucere - the stone has the same high contrast brilliance as one may expect from a traditional step cut (and not from brilliant cuts like the RBC or the Regent), and higher light return. Now... of the two measures for light return I wold rather look at the "stereo" since stones are not observed motionless when worn. This makes little difference for brilliant cuts, but allot of difference for step cuts. An Asscher will match the "stereo" light return, but probably fall behing allot for the mono (given it's larger facets, I would think). I would call both the Lucida and Lucere an attempt to improve brilliance and keep the look of a step cut in place. Since the models are so close, they should be expected to achieve matching optics. The branded Asscher does the same, I would think, only more true to tradition. Ana "The greatest experts are only as good as the sum total of what they have seen." [Souren Melikian]

researcher Ideal Rock Total Posts: 2,440 Last Post: 5/26/2008 Member Since: 4/27/2004	I can't tell you much about the difference in cuts, but thought I'd let you know that it probably had to be below 4 cts because I was just shown a 3.22 ct stone, H in color, VS2 clarity for $92,000. Interestingly, I purchased a princess of the same weight, I in color, SI1 clarity for under $18,000 that faces up just as white, is 100% eye-clean, and scored VH-VH-VH on the BS. Crazy, huh? If I were in the market for another stone I would DEFINITELY choose the jubilee over the Lucida--they're most likely better performing stones.

You've gotten some good spot on answers except Valeria confused your request with a Regent instead of a Jubilee. Gotta give her credit though as her answers are always well researched and I love how she demonstrates her points with graphics. You're hired Valeria! Just to add to the bit that has been posted (as both Valeria and limey have pointed out) the most obvious difference is the step cut crown on the Lucida/Lucere vs the brilliandeered crown of the Jubilee. The other difference would be the angles to which the crown and pavilion facets are cut on each. Now I have not had the opportunity to analyze a Lucida loose but I have seen them mounted. I would not make a blanket statement that all Lucida's have such and such an appearance but the few that I have seen ranged from glassy looking to have very good fire/brilliance. Ie. the facet structure/arrangement on each Lucida is the same (as it is with the Lucere) but the varying proportions to which they are cut will affect each individual diamonds light output which will of course affect to a certain degree it's face up appearance. I'd love to get my hands on a loose Lucida and run it through our excruciating optical torture tests for review. Rhino Good Old Gold
