Hello Everyone! My name's Bennie Ulibarri owner of Gemshow Lapidary™ Currently I work in the gold and diamond exploration field doing private consulting for large companies on a fee and royalty basis. I do everything from finding the targets to field evaluation to filing and monumenting the claims. I'm an avid hiker , inventor ,gemcutter and genuine Colorado miner. Opals are my favorite stone to work with, in either the bezel making and setting or the cutting and shaping, even just playing with the rough :) When I first began cutting opals a good friend of mine let me borrow Paul Downing's "The opal book". I couldn't get over some the standards mentioned in this book!. Mr Downing's book is where I learned valuable lapidary principles specifically for opal cutting. Invaluable info! , like When a light bulb reflects back off the dome of an opal, if the bulb reflection stretches ,the reflection stretches from a flatspot. Several years ago I invented technology for cutting my Opals and I'm proud to announce all my stones don't even have one flatspot in the polish , even under the powerful magnification of the microscope, All our stones have a Flawless Surface. Did you know Opal Auctions is the only place to buy Screamin Bright™ Gems and Jewelry, we are only making 2,000 pieces bearing the Screamin Bright™ trademark. All stones bearing this Trademark are serial numbered collector pieces, pending review with the USPTO in March-April we will move from ™ to ® proofmarks, There are very Strict conditions to be a Screamin Bright™ stone as they are all Hand graded by me personally ,Without any special circumstances these opals show the loudest colorplays and I show them with white background and only one light bulb , Each piece cut and graded by Bennie Ulibarri founder of Gemshow Lapidary™ includes a hand written letter of authenticity . Serial numbers are starting at 2000 and counting down to 1. in the distant future we may have an interactive "who owns it now" databank.that can be updated ,basically registering new ownership. And we will be glad to authenticate any Screamin Bright Stone... Screamin Bright pieces are always going to be extra nice in hand. All of our opals are cut and shaped with my very own Flawless Dome Felt™ and silicon carbide and polished with Über Cerium Oxide™ Old school is new school
