![]() ![]() Tours of the mine are offered periodically on an extremely limited basis. The OdySea store also features a mine exhibit where you can learn more about the process. store, located at the OdySea in the Desert shopping complex in the Scottsdale area, or Sami Fine Jewelry in Fountain Hills. Cavano calls it a "labor of love," not necessarily profit.įour Peaks amethyst can be found at the Four Peaks Mining Co. The stones are tumbled, cleaned, sent overseas to be processed and, in the end, only "a few handfuls" are used in jewelry. There are no special machines and all mining is done by hand with a hammer and screwdriver to minimize potential damage to the six-sided crystals.Ĭavano said approximately one ton of amethyst leaves the mine each year and produces around 50 pounds of gemstones. Blank said he plans to work in the mine "until I can't do it no more." The couple is so passionate about their work they named their daughter Amethyst. "It's my life, it's who I am, it's what I do," he said. "My grandparents - they collected gems and minerals so I was just naturally drawn to them," Blank told ABC15. They spend roughly half the year, week on and week off, working eight hours per day inside the mine and living in a small, solar-powered home near its entrance. ![]() ![]() Mike Blank and his wife, Ty, are the site's only two miners. It's small and difficult to reach, only accessible by helicopter or a grueling three- to four-hour hike. The amethyst leaving Four Peaks has other trace elements including manganese and chromium. ![]() It takes "millions of years" for the stones to be formed, Cavano said, requiring natural deposits of silica, iron and hot water. The type coming out of the Arizona mine is known as "Siberian Red Amethyst" and, as you can probably guess, the only other place it's known to be found is in Siberia. There is speculation that amethyst from the mine was used in the Spanish crown.Īmethyst is quartz that contains other elements and is created through a natural process that gives it a purple color. Cavano said the site is believed to have been first discovered during the 18th century by Spanish settlers. Difficult templates include sequences with GC rich region, hairpin, shRNA and RNAi etc.With its distinctive deep purple color, Kurt Cavano knows the stones coming out of his mine are "really, really special." He holds the claim to the Four Peaks Amethyst Mine, nestled in an area around 7,000 feet between the third and fourth peaks.ĪBC15 was invited to tour the mine with a small group and learn more about its history. If that is the case, we will use Laragen's proprietary chemistry for difficult templates to get around it. For example, it is difficult to sequence a GC rich region with regular BigDye premix. Difficult Templates: Some templates are difficult to sequence.However, since PCR reactions is more robust than sequencing reaction, some primer may work well for PCR reactions, but not for sequencing reactions. If the primer works as a PCR primer, it usually works fine as a sequencing primer. Based on our experience, you should test your sequencing primer as a PCR primer first. Too much or too little primer may result in sequencing failures. Make sure that your primer concentration is correct. Direct access to both sequence and translation. Primer concentration: 10 pmole of primer is required per sequencing reaction. 4PeaksOverview Reading and writing of most common trace file formats, including ABI, SCF, CTR, ALF and ZTR.Elute with water or EB(10mM TrisHCL, PH8.0) EDTA inhibits sequencing reactions, Do not elute DNA with TE buffer.On the other side, too much DNA will also interfere with the reaction. Not enough DNA: Insufficient DNA will lead to insufficient signals or failed reactions.Do not overgrow the cultures and do not overload the spin column. We recommend Qiaprep Spin Column miniprep kit to prepare plasmid DNA. Contaminants are ethanol, protein, salt, PEG, EDTA and genomic DNA. Poor quality of template DNA: Contaminants in the DNA prep will interfere with the reaction and cause failures, noise and miscalls. ![]()
