Hello all. A few months back I bought my first rough opals from Ethiopia. After doing research, it was difficult to find a cutter here in the Washington D.C area, so I was forced to get them cut in Ethiopia. Since I am new, it’s very difficult for myself to judge the quality of the cut, and the quality and value of opals after being cut. I want to learn, any valuable input will be highly appreciated. Thank you.
Look at them with a 10X. The surface should be glassy smooth with no sharp sanding marks. It’s easy to get a smooth finish with cerium oxide, but some cutters get lazy and finish with 14k (or even 50k) so the finish will not perfect.
The cut looks like standard third-world commercial. Some of them have good color, but it’s difficult to judge from a single photo. However, a few are not much above potch.
I don’t know what you paid, but these may give you something to compare to.
List/Retail on the first two is about USD $3ct, the third lot is much nicer and is listed at USD $12ct retail.
Contact me directly for wholesale pricing please.
