Presidium Synthetic Diamond Screener II
Enhanced with additional features, the Synthetic Diamond Screener II now tests for diamond melees as small as 0.02 carats with instantaneous results, through the measurement of UV absorption.
The Synthetic Diamond Screener II is developed by Presidium to help screen out Type IIa colorless diamond, which is likely to be laboratory-grown and created through chemical vapor deposition (CVD) or high pressure high temperature (HPHT) syntheses, from the natural Type Ia colorless diamond.
When subjected to this deep UV irradiation, Type Ia and Type IIa diamonds each absorb different amount of UV light. Type IIa diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in the light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.
Features
Advanced technology that measures a diamond���s UV light transmittance ability
2 color coded (blue/red) indicator light bars to give a low or high reading of UV light absorption with blue light indicating Natural Diamond and red light indicating Type IIa Diamond
Instantaneous clear results within 2 seconds
Blue light to illuminate the testing pad
A 5mm metal bar to conveniently raise the test probe for successive testing on loose stones
Test button will blink in red to alert if the device is unable to detect any stones on the photo-detector
Auto shutdown of interior LED light source for safe testing when lid of device is open or when Start Test button is not activated
USB port for alternative power source and connectivity
Exterior base foam padding to ensure non-slip sturdiness and prevent scratches to surfaces
Low battery indicator
Energy-saving auto power-off of device after 10 minutes without operation

Let customers speak for us
Great Quality bench for the price! PMC Supplies customer service was great. Very Easy to assemble and set up.
Excellent hands down! This is the best especially if you use resin of any brand any kind!
So far I’m loving this bench. I’ve had it less than a week but I am impressed not only by the workbench but by the customer care at PMC Supplies. The bench arrived in three boxes that were not too heavy that I needed help going upstairs. There were probably 20 wood pieces and a hefty bag of hardware, but in just about two hours I assembled the workbench myself. The top of the bench was cracked upon opening, which was odd since it was inside three boxes. When I contacted PMC Supplies about this, they offered to replace the top or refund part of my purchase price so I could repair it myself. In any case, the bench and shelf have plenty of room for nearly all my tools. I’ve been able to empty three medium to small tool bags and fully stock the bench. I’ve added a flex shaft mount and tool and I will be adding drawer pulls to the drawers to make them easier to open.
Pros
Easy to assemble.
Sturdy, all-wood construction.
Shelf has plenty of needed space for tools and storage.
Excellent customer service.
Cons
Wood is somewhat soft, maybe pine? Doesn’t really matter as any bench will show signs of wear over time.
Holes on shelves are too small for some tools, particularly hammers.
Top was cracked upon arrival but PMC Supplies made it right.
This is the perfect product for my sand casting applications! It packs the petrobond well - and easy to use. Highly recommend!
Works Perfect. Good Quality.. Will buy again
I have been on the lookout for a more affordable diamond coated tipped tweezers and I have finally found them! I'm not a jewelry maker but I use these for volume eyelash extensions. There is a lash company called Novalash that makes a pair but it is $104 and I couldn't fathom spending that on one pair. I went on the hunt like a hawk to find a pair of diamond dusted tweezers at a more affordable price and found them on your site. Please don't discontinue these tweezers and I would like to know if you are going to carry more straight tweezers with Diamond Coated tips? Thank you PMC supplies!
Great furnace great customer service.
I received the kit in 2 days. Crazy fast. I ran it through a bag of cans to see how it works. I could feed it a can every ±20 seconds. Works great. I'm confident this will be a good addition to my pour process.
This crucible is absolutely worth every penny! Been kicking the heck out of this thing for a year and a half, still rocking. I actually cracked it on the side from a thermal variance (my fault-newbie), and it healed itself again. The vitrification is essentially self healing. I am here to buy another, a larger one, right now.
Great furnace! I’m new to this hobby, so I wasn’t sure about this website or this product but both have been excellent! The furnace has had about 10 fires and other than some discoloration, no real issues. The stone in the bottom broke around the 8th fire but still does the job. This furnace can get hot enough to melt copper EASY. I haven’t tried anything else yet.
Absolutly perfect for brass and aluminum used several times and never have problems looks just like I just took out of the box 5 star
I love this furnace, I am very pleased with my purchase, it will be useful for a very long time. If unsure which furnace to get, this one will certainly not disappoint... Have fun!
Just as advertised, it works great to melt brass and copper in. I will purchase this again in the future.
Just as advertised, it works great! Speedy shipping and a great product for a great price!
