QUARTZ CRYSTAL CLUSTER W 2 SCEPTERS AND ROSE QUARZ, LAB GROWN IN CLEVELAND OHIO

Description: Quartz crystal growth is one of a few intriguing natural processes that has been copied from Mother Nature and implemented in the laboratory. Industrial growth of commercial quartz crystals for their unique piezoelectric and optical properties has produced the necessary components for electronic and optical devices for over 65 years already. XSTALSHOP (division of R&D XTALS, Inc) has recently adapted this hydrothermal growth process with the aim of creating natural-looking crystal specimens for mineral collectors, museums, researchers, educators, as well as objects d’art for other buyers. The term "hydrothermal" is used to describe a crystallization method utilizing superheated (about 660 F (350 C)), mainly alkaline aqueous solutions at very high pressure, exceeding 10,000 psi (>70 MPa). The crystals are grown in an airtight, thick-walled, steel vessel called an autoclave. We called that autoclave as "high pressure cooker". Pressure in the autoclave is built up solely by electrical heating. Crystals begin forming on "seeds", which are broken natural quartz clusters, and/or slices and pieces of natural or grown quartz crystals. Crushed pieces of naturally abundant milky vein quartz are the nutrient material for growth. This process is complex, very energy intensive, requires specific controls, and can be dangerous. It cannot and should not be done at home. Researchers from R&D XTALS have over 63 years of combined experience with hydrothermal growth techniques for quartz and several other crystals, and have the requisite educational background in geology and mineralogy. They also have the necessary patience to constantly monitor the batches of growing crystals over a long time from a few months to a few years. However, this is just a blink of an eye compared to the eons-long time scale required for some natural crystal growth. The shiny faces on each crystal are built up, molecular layer by molecular layer, undisturbed, and in full darkness. They have not been cut, polished, or touched in any way to enhance their beauty after growth. Close inspection may reveal faint traces of the seed inside individual crystals, but all of the external faces are natural shapes with natural luster. Some crystals or its pieces are hydrothermally etched after growth to reveal structural peculiarities and defects, which are important for scientific, educational, and industrial purposes. Quartz is a hard mineral and cannot be scratched easily, but it is brittle. Many our specimens are placed in a plastic display cases to prevent dust accumulation, protect crystals against chipping and breaking and protect skin against the cuts. The crystals can be cleaned with warm soapy water and air duster indefinitely, and they are insoluble in practically all chemicals. Just avoid touching the very sharp edges and points. These quartz crystals will last for a long time to educate you and decorate your mineral display at home or at mineral shows. Some sensitive people perceive positive energy coming from our quartz crystals (observed in many mineral shows). They use them for healing themselves and others; but everyone can find enjoyment and improved mood just by looking at these sparkling crystals and moving them in the light.You are bidding on one exquisite specimen of the lab-grown quartz crystal cluster with one copy of "Rocks & Minerals" magazine, shown on the pictures. This beautiful cluster was grown with broken, natural, milky quartz cluster as a matrix. Red color broken piece of "Pecos Valley Diamond" quartz was added to composition and developed into nice pinky "hay stock" cluster.One more crystallization run was used to develop two proprietary grown right-handed quartz scepters on the top and intergrown to the matrix. Water clear small matrix's crystals are randomly right- and left-handed crystals. An additional small chip of lab grown quartz was used as a peg support under bottom of the cluster to prevent its rocking in autoclave. The growth time for this cluster was about nine months total.Each specimen like this is absolutely unique and one of a kind. Specimen can be signed with crystal grower’s initials by diamond scriber for buyer request, right after cleared payment. Specimen measures are about 12.5 cm (W) x 9 cm (D) x 8 cm (H), weighs about 492 grams (1.1 pound).This specimen goes with one copy of "Rocks & Minerals" magazine, Volume 90, issued July/August 2015. Pages' 379-384 article, named "A Marriage of Science and Art - Creating Quartz Specimens in the Laboratory” would be signed with crystal grower's autograph by buyer request. Just contact seller via eBay after your win a bid to tell us, which name, if any, that article should be signed to and what marker's color you would prefer for it.You can find an additional information about quartz crystals and their growth on the Wikipedia website with key words: quartz, crystal, single crystal, piezoelectricity, crystallization, hydrothermal synthesis, seed crystal, crystal growth, etc. Mindat.org web site is very informative for quartz also.Thank you for buying our specimens.
