Diamonds are a girl's best friend and online stores are the best friend of diamond ring buyers. Diamonds always look better when they are sparkling on your hand. By purchasing from online stores you will find all the information that you will not be able to find in local jewelry stores. Online stores also allow you to shop with privacy and comfort from your home.
Everybody has to take a picture of some alcohol right? so here is mine. Used a bit of off camera flash here, the canon 430ex is directly behind the bottle shooting up at 1/4 power. Camera is at f16 1/250 and 50mm. the bottle is sitting on dark polished granite which is where I am getting the really nice reflection.

FEATURES OF SINGLE CRYSTAL SAPPHIRE
1. Sapphire has a high optical transmittance, so it is widely used as microelectronic tube dielectric material, ultrasonic conduction element, waveguide laser cavity and other optical elements, as window materials for infrared military devices, space vehicles, high-intensity lasers and optical communications...
2. Sapphire has high rigidity, high strength, high working temperature, abrasion resistance, corrosion resistance characteristics, so it is often used in harsh environments, such as boiler water gauge (high-temperature resistance), commodity bar code scanner, bearing and other precision manufacturing (wear resistance), coal, gas, well detection sensors and detector windows (anti-corrosion)...
3.Sapphire has the characteristics of electrical insulation, transparency, good thermal conductivity and high rigidity, so it can be used as the substrate material of integrated circuits, such as LED and microelectronic circuits, ultra-high-speed integrated circuit.

LOOK AT WHERE SAPPHIRE WAFER APPLIED
1. Semiconductor LED industry (MOCVD epitaxial GaN substrate)
In general, C-plane sapphire is needed in this area. R-plane or M-plane mainly used to grow non-polar/semi-polar plane epitaxial layers to improve the luminescence efficiency.
2. The growth of III-V or II-VI compound semiconductor.
3. Microelectronic IC applications especially Very High-Speed Integrated Circuit, SOS
Generally, it is a silicon heteroepitaxial deposition on R-plane sapphire.
4. Hybrid microelectronics
Hybrid microelectronics products are mainly HIC and MCM. It has high requirements on the substrate, while sapphire's characteristics such as stable dielectric constant and low dielectric loss make sapphire wafer the most commonly used substrate for HIC and the main substrate for MCM. Generally, the A-plane sapphire wafer is needed.
SAPPHIRE WAFER PROCESSING
At the very beginning, we have a crystal boule.
Crystal growing: Produce high-quality sapphire monocrystals via furnace.
Sapphire ingot processing: Drill out the ingot, Ground the ingot, Quality inspection.
Then we get the sapphire ingot.
Orientation: Position the ingot on the sawing machine.
Sawing: Cut the ingot into thin wafers.
Lapping: Lap the wafer to remove the scratched layer and improve its flatness.
Chamfer: Trim the edge of the wafer into an arc to improve the mechanical strength, to avoiding stress concentration.
Polishing: Reduce the surface roughness to reach the epitaxial wafer grade.
Cleaning: Remove dirt from the wafer surface.
Quality inspection: Inspect wafer with a high precision instrument to meet customer's requests.
Finally, we get the sapphire wafer.
