Recutting and Repair
Before and After photos of a typical "native cut" gemstone where weight is emphasized over optical performance.



Here is a terrible example of faceting technique in the ďBeforeĒ photo. Isnít it strange how such awful looking stuff can be sold with a 70% window? The material is very unusually patterned amethyst. Nevertheless it was turned into a very striking unusual gemstone when cut properly in a pattern more suited for itís color zoning condition.


  Here is what was done with a typical native cut Heliodor with a huge window which obviously was cut to sell carats with no regard for beauty. Now it can be worn with pride.


The pavilion of this gem zircon was recut leaving
the face-up size unchanged.


A spinel with obvious window recut with 13 properly
placed new pavilion facets. Weight loss was 9% with
no change in size.




Here is a 3.35ct badly abraded Tanzanite which was native cut with a very shallow crown and a very large table. Recutting with proper crown proportions allowed the stone to reveal more optimum beauty.



This 10.3ct Aqua has seen much wear and reveals a window from the original cutting many years ago. A complete recut using modern faceting thinking and execution gives the stone a new life.



Here is a badly windowed aquamarine "look alike" cut to simulate an aqua. Turns out the material is blue topaz. Now we have a brilliant cut topaz worthy of being called a gem.



An unusual green sapphire showing original "Native cut" with little green showing, with lots of darkness and an obvious window, and the much improved color and brilliance after recutting only the pavilion . Weight is 5.28 ct after repair. Weight loss was 17% with no change in the 12 x 9.3 mm face-up size which reveals how much extra weight the original cutter left on at the expense of optical performance.



Here is Blue topaz cut originally to resemble a more expensive aqua marine in the typical step cut design so common with aqua marine. But , as is frequently the case, the native cutters leave too much bulk on the pavilion to increase weight and leave a window right down through the middle of the stone. The client had let the stone languish for years in a draw because of it's appearance and then decided to have it converted into a real gem. Now it is a brilliant topaz, worthy of the name Gem, not some poor looking imitation of an aqua marine. We lost less than 10% face-up size and about 30% in weight going from the step bar cut to the pointy brilliant design. It is about 13 x 11 mm and 12.35 ct.
