ABOUT THE ITEM

Paraíba tourmaline is an exceptionally rare type of tourmaline prized for its vivid, neon-like bluish-green hues.

In 1988, gem miners in Paraíba, Brazil, uncovered intensely saturated blue and green tourmalines unlike anything previously seen.  Their extraordinary color is caused by trace amounts of copper, often accompanied by manganese.  Since this initial discovery, copper-bearing tourmalines with similar colors have also been found in other parts of Brazil, as well as in Nigeria and Mozambique.  Even when mined outside the state of Paraíba, these gems are still referred to as Paraíba tourmaline if their distinctive color is due to copper content.

Colors range from neon blue, blue-green, and greenish blue to mint green, and more rarely violet or purple.  Paraíba tourmalines are often heat-treated to enhance or adjust their color.

This elegant 18K white gold designer cocktail ring showcases a rare pear-shaped Paraíba tourmaline, weighing an estimated 2.50 carats by formula.  Its striking neon green-blue hue attracts the eye instantly.

The Paraíba tourmaline is framed by a three-row diamond surround, totaling approximately 0.60 carats.  The diamonds are well matched, grading G-H color and VS2-SI1 clarity, and compliment the oceanic hues of the tourmaline nicely.

The mounting is presently a size 7, and is hallmarked "750" along with a maker's mark inside the ring shank.

The ring is accompanied by GIA Tourmaline Origin Report No. 5231665065.

You're unique and rare!  Why shouldn't your jewelry be, too?

Good Multipurpose Hub, Some Limits on Power Draw
I use this with a Dell Latitude 7430 with a 65W charger, and it works fine as a docking hub. The only problem I've encountered is when rebooting, the boot will pause with a warning message to tell me that the laptop may encounter reduced performance because it isn't able to receive the full 65 watts. I don't get that warning if I'm not running the power supply through the hub. Otherwise, if I just use the hub as a port extender everything is fine. It has a compact design and is reasonably lightweight. It would be ideal for travel. Like my other Anker hubs, it's well constructed and doesn't feel cheap although it's good value for money.

I don't know how I ever lived without it.
I'm very happy with this device. My laptop doesn't have an ethernet port and only has one USB-C SuperSpeed port, so I bought an ethernet to USB-C cable to connect my ethernet switch to the Anker and into my laptop's USB-C port, and it works great. I don't need a fast internet connection for the things I do, so my service is only a 50mbps symmetrical up/down connection, and that's what I get even while transferring files from my external between other devices, charging my phone, and using composite devices. I bought the Anker 100W Compact and Foldable USB C Charger for it and it charges my S24 extremely fast. It's very well built, yet super lightweight. I love the sleek, slender design. It's the perfect size to easily slide into a pocket, store in a desk drawer, or keep handy in a laptop case or backpack. Using it is easy. Just plug it into your computer and plug your devices into it. Just make sure you have a power supply for it if you're charging or powering other devices, using external storage, or running anything else that taxes USB power. I have had ZERO connectivity issues with it — no random disconnect/reconnect blips, no failed transfers for huge amounts of data that have taken up to 45 minutes, no static his or crackle when my headset is running through it... no problems at all. It's actually kind of spooky now that I think about it... I can't recall a time I've ever had a similar device that didn't have some nuance that got under my skin, like a loose connection, random disconnections, having to reinstall the drivers all the time, or having to troubleshoot just to get it connected for the first time. The most stress I've put it through was with my keyboard connected, ethernet running through it, my S24 charging and transferring about ~20gb of pictures and videos to my 2T external HD at the same time that my laptop was transferring about ~500gb of media and documents to the HD, too, and I was surprised by how warm it DIDN'T get. My only complaint is trivial and unique to my situation — I wish output cord was longer. About six inches would do. My laptop sits up on an adjustable stand that clamps to my desk, and the end where the output cord is hangs a few inches off of my desk. This puts extra stress on the USB-C port and can wear it out faster or damage it. I haven't had a use for the HDMI port yet, but I eventually will. I use all of the other ports for my work and personal devices, though. These include: a 2tb external hard drive; a Poly Blackwire 3320 Series headset; a dongle for a wireless mouse/keyboard combo or a wired keyboard and a dongle for a wireless mouse; my Galaxy S24 charges and transfers files through it super fast; I have several thumb drives ranging from 20gb to 512gb that I regularly use; I recently bought an RCA/S Video-to-USB converter to digitize old home movies I plug into it, too.

Anker wins again.
Worked well for usb hub but hdmi was not reliable. Disappointed because usually Anker products are good quality. UPDATE: Anker voluntarily offered a refund so my faith in Anker has been fully restored.

Perfect with a MacBook
The Anker USB C Hub works great with my MacBook Air. I paired it with the Anker 100W MacBook charger which plugs directly into the USB C Hub so I only have to plug in one cable like a true docking station. My Apple MagSafe charger stays in my briefcase so I always have a charger when I'm away from my desk. I also plug in my external monitor and an external hard drive. I highly recommend this product!

Great All-in-One Hub, With Few Limits
Style: 8 in 1 【2 HDMI + Ethernet】
This is a solid USB-C hub if you need to expand your laptop’s ports. It covers all the basics—dual HDMI, USB ports, Ethernet, and SD card slots—all in a compact design. Setup is plug-and-play, and it’s been reliable for everyday use.  The dual monitor support is a big plus, but keep in mind on Mac, both screens will mirror instead of extend.  Downsides: it can get a little warm with heavy use, and you’ll need your own power adapter to get full charging performance. Bottom line: Great value and functionality for most users—just know the limitations depending on your device.
