Types of Diamonds Available at Cross


Exceptional ideal-cut diamonds are why so many come from throughout New England and across America to buy their diamond engagement rings from Cross.

THE ROYAL IDEAL - This is the diamond that when she walks into any room anywhere in the world there can be no diamond more brilliant, more beautiful then hers. A Cross Royal Ideal diamond is the ultimate in cutting precision possessing fire, light & life exceeding all others. We specialize in colorless and near colorless Royal Ideals that are triple excellent and are of classic Tolkowsky proportions.

These diamonds are the epitome of consistency and performance. Each 1/3 carat and over is accompanied by either AGS or GIA certification as well as a Cross Appraisal attesting to its quality and value. (ExExEx)

SIBERIAN WHITE IDEAL - Siberian White Ideals possess all of the critical angles and proportions to achieve maximum brilliance and shine. They have tighter proportions then American Ideal and are near colorless and submicroscopic clarity. Siberian Whites are some of our most sought after diamonds. (Ex)

NEW AMERICAN IDEAL - Very nice cutting reflecting the new liberalized GIA & AGS Performance Standards including Hearts & Arrows, and many other name brand diamonds. All color and clarity grades. (Ex)


For all diamonds sold by Cross, we provide final transfer of ownership papers, appropriate certification as well as appraisal documentation to enable you to obtain insurance coverage. Proper documentation represents the pedigree of your diamond and is an important part of your family's historic record.

Cross Goes Far Beyond the Sarin
We own a state-of-the-art, $25,000, Sarin diamond computer analysis machine. It is capable of a complete analysis and computer printout detailing diamond proportion specifications. The Sarin Computer System can be programmed to determine Ideal proportions and infinitely minute diamond proportion deviations from Ideal allowing the most detailed mathematical qualitative documentation for diamond cutting ever available.

It is important to note the American Gem Society (AGS) classic Ideal cutting standards shown here are the tightest in the jewelry industry. The Sarin can also be programmed to American Gemological (AGL) or (EGL) cutting standard, a bit looser than AGS standards with either numeric or word descriptive cut grades. When a Sarin is programmed to other systems than AGS standards, the grades are typically looser. Therefore any Sarin report and its conclusions of a final grade are not necessarily a guarantee of proper cutting. Specific Sarin proportions and percentages must be compared against the classic Ideal AGS cutting percentages and angles chart. Finally, a Sarin machine does not evaluate polish and symmetry characteristics. This must still be done by the human eye. While a Sarin analysis can pinpoint true Ideal proportions to AGS standards, it is a purely mathematical analysis. As grades deviate from Ideal the Sarin does not accurately assess beauty. Cross' diamond cut grading system follows Sarin proportions for Ideal Cut grade.

Cross' system is based on beauty and brilliance, rather than mathematical formulas, therefore Cross Cut Grades for 1-10 are likely to differ from Sarin grades. Sarin currently produces three models of diamond measuring machines. Cross has the top of the line. The same model used by the world's finest cutting factories and in all American and international gem grading laboratories. The other two Sarin machines produce less accurate reports, especially the retail counter top model. It is important to remember that any Sarin machine can be programmed to appear to draw almost any conclusions. The proof of Ideal proportions is in direct correlation to the American Gem Society classic Ideal standards. Final proof of Ideal Cutting still relies on the human eye.

Impeccable Craftsmanship
Cross is known throughout America for the finest cut diamonds, superbly crafted mountings, but even more important: the final step, diamond setting. We have three master diamond setters on staff who are the best in America. While most diamond setters are on piece work, Cross diamond setters are on salary. The first rule of our diamond setting shop is, "take whatever amount of time is necessary to set the diamond most securely and most beautifully." This philosophy results in rings that sing with brilliance and beauty, rings that are made for a lifetime of love.
