THE MOST COMPLETE INFORMATION PACKAGE YOU'LL FIND ON THE NET CONCERNING
YOUR DIAMOND PURCHASE.

Here at the UDIS we sift through the hype and get down to the hard cold facts concerning the stats and data on each and every stone you're going to consider purchasing.

In the tradition of living up to our name, when you view diamonds for sale on the UDIS you will review ...

• The diamonds Lab Report (GIA, AGS, etc.)

• The diamonds Sarin/MegaScope analysis (the labs can make mistakes you know). I double check all stones via a computerized analysis pertaining to the diamonds cut dimensions. The computer automatically assigns the AGS proportion cut grade to any diamond it analyzes.

  * Recommended software for viewing some of the data we feature.*
  Virtual Models: On many of the stones featured there are virtual models you can view which also give quality assessment of the cut and the diamonds light return via the studies and software of Moscow State University. The free GemReader software has been updated so the links on some of the diamonds are of the old version which will not install.  Get the new updated GemReader software at this link.
  Sarin Web Viewer: Sarin's latest Web Viewer can be downloaded via this link.  You must have IE 5.0 or higher running a Windows PC to view the various & awesome Sarin Reports generated via the DiaMension 2000 and the new DiaVision software. If you are running a different browser or a Mac contact us and we'll give you any details you want on the proportions either via screen shots or MegaScope.
   

• Microscopic Pictures of any stone you'll consider under 10x - 63x magnification with dark-field illumination. When diamonds are analyzed in the labs it is performed under microscopic examination with dark-field illumination.  Websites are popping up offering pictures under magnification with overhead lighting or soft light. Don't fall for it ... overhead light masks inclusions and imperfections. Dark-field LIGHTS UP inclusions and imperfections making the critical analysis easier. Don't you want to know what's making your diamond the clarity it is? To see an example see my homepage on clarity.

• LightScope™ Analysis.  The LightScope™ is one of today's most advanced gemological pieces of equipment that shows both laymen and gemologist JUST HOW MUCH light is coming out of the diamond in relation to how much light is leaking out of the diamond. It also shows us the intensity of the light being reflected (as indicated by blacks and dark reds). The better the cut quality the less leakage and more perfect it's internal pattern will be!  The LightScope also lets us analyze a diamonds optical/internal symmetry.

• Hearts and Arrows Images.  When appropriate, with Ideal cut diamonds actual pictures are taken of each diamonds Hearts and Arrows pattern letting us know diamonds internal symmetry, and the exactness to which it's precision has been cut on a 3 dimensional basis.

• BrillianceScope analysis.  This latest piece of lab equipment tells us how much white light, colored light and scintillation is coming out of a diamond.  

• Free laser inscription of any diamond. Some diamonds are already laser inscribed via AGS labs (as in the example below). Our H&A diamonds accompanied by GIA Reports are not inscribed by default (unless there is a picture showing otherwise). If you would like your diamond laser inscribed simply ask and we will do at at no additional expense. When we do inscribe a diamond we inscribe it like the image in the 2nd photo.

Some sites offer maybe one of two of the services above we provide for our clients but add to that the refund, exchange, trade-up and buy back policies we offer to our clients and we're pretty tough to beat.

The diamonds listed here are the stones that we have in house.  As we are consistently purchasing for stock it's almost impossible to always have every diamond in house listed here for sale. If you'd like to know what else I have in stock that may pertain more to your needs, please don't hesitate to either call me at 516-798-5151 or drop me an email. 

NOTE: NO DIAMONDS LISTED FOR SALE ARE CLARITY ENHANCED, LASER TREATED, COLOR TREATED or anything of the sort in any way unless otherwise noted.

About "Diamonds For Sale"
Before viewing diamonds for sale here OR IN ANY JEWELRY STORE, IT IS HIGHLY RECOMMENDED that you at least read through the rest of our tutorial especially our chapters on cut. I and other jewelers/gemologists will be using terminology relating to the diamond that quite frankly will be alien to you unless you understand the terms related to cut, clarity, color and weight.

Every week we buy diamonds.  If you've taken the time to acquaint yourself with the various rigorous tests I put a stone through before I make a buying decision, I'll have you know that I'm not going to waste my time putting up diamonds here that I can't offer for competitive prices.  Not only are you going to get the most competitive world market prices on diamonds here BUT YOU ARE GOING TO SEE WHY THEY ARE THE PRICE that they are.  I've had some of the toughest shoppers put me to the test.   You can read some of their testimonies here, but for your own conscience let me familiarize you with "our refund/exchange policies" which are at the top left of this page.
