Always Worth the Extra Cost

Posted on Jun 6, 2017 in Journal, Notes & Quotes | No Comments

The quality of cutting is often overlooked when pricing a colored stone unless it is a native cut. However, a precision cut gem will always present a far brighter and more desirable appearance than is observed in an average make. Precision is cutting is always worth the extra cost and a premium must be considered […]

Dangerous Feathers

Posted on May 25, 2017 in Gemcutting, Journal, Recut & Repair | No Comments

Gemstone repair is one of the services I offer to the jewelry trade. All gemstones (diamond included) will take wear over time, especially if they’re used in rings. Happily, the great majority of the stones can be repaired with minimal loss. But occasionally the damage done cannot be removed. For example: I recently received an […]

Sneaky Synthetic Sapphire

One of my clients purchased a fine selection of larger sized sapphire rough from Umba, Tanzania. The stones were all nicely shaped and great colors. But in reviewing the stones for cutting, I noticed one that didn’t seem quite right. It seemed to be a water-worn sapphire cobble, but the fracture pattern on one side […]

Old European Cut

As you may know, the Old European Cut (OEC) design was a 19th century evolution of earlier, simpler designed use for diamonds. Eventually the OEC was superseded by better performing designs, especially by what we now call the Standard Round Brilliant (SRB). While it is completely true that the SRB optically out-performs the venerable OEC, […]

Q&A: Heating Zircon

Question: I am curious about the process of changing the color to colorless. I had read online that the color can be changed by heating at home, is this so (or just silly internet advice)? I am considering changing its color if so… Answer: Yes, you can heat zircon yourself and without special equipment. Many […]

Recut Project: Untreated Yellow Sapphire Round

All large sapphires are rare. In today’s market, untreated sapphires of any fine color are very rare indeed. Sizable round, untreated, fine color sapphires? Well, suffice to say that they’re almost impossible to source when you want one. That’s why I invested in this large, untreated yellow sapphire at the AGTA show in Tucson this […]

Spessartite Garnet Recutting Project

Last month I received a very large spessartite garnet from one of my wholesale brokers — over 18ct! Spessartite this large is rather rare, but because of the cut and obvious inclusions, it just wasn’t selling for him. So, after some discussion, we decided the stone would be best recut to a more salable shape […]

Recut Project: Yellow Sapphire Square Cushion

I just wrapped up a fun recutting project. A client needed a 6mm square cushion yellow sapphire with fine color, high clarity and untreated (if possible). I was able to find a badly proportioned square at Tucson this year and was reassured by the vendor it’s untreated. I’ll be sending the stone to the AGL […]

Danburite Asscher Wedding Project

Posted on Jan 19, 2015 in Gemcutting, Journal | No Comments

Last Summer, I was commissioned by Drew of DWDesign in Janesville, WI to cut a danburite asscher for a wedding ring set. Drew requested a portion of the rough from the main stone be cabbed for the man’s ring. It was a little unusual, but I didn’t think much of it at the time. Now […]
