About Us


Quality and Value since 1950


Kingsbury Jewelers was established in 1950 in the heart of the theatre district of New York City. The original location was at 1504 Broadway across the street from the famous landmark the Paramount building. My father founded Kingsbury Jewelers after he spent years designing fine jewelry for some of the finest and well known jewelry companies. He prided himself with providing his clientele with the finest diamonds, semi-precious and precious gems from around the world. Kingsbury Jewelers offered quality, one of a kind masterpieces designed for the elite buyer by appointment only.




In the 1950’s the Metropolitan Opera was located near my father’s store. My mother had recently moved from Argentina where she began her opera career as a child prodigy. The Metropolitan Opera brought the Argentine star, Delia Rigal to the United States where she continued to gain world acclaim singing on one of the world’s most famous opera stages- the Metropolitan Opera. The Opera was always on the quest to find new jewelry designers who could create breathtaking masterpieces for the stars to wear on stage during their performances. As destiny would have it, the Opera referred my mother to meet with a potential new jeweler at Kingsbury Jewelers. She met the very handsome and debonair proprietor, my father. Working closely with my mother he was able to envision and create the magnificent jewels the opera stars needed to adorn themselves. It was my father who designed beautiful handcrafted pieces worn by some of the greatest opera stars on the stage. The rest is history!

According to Wikipedia, Cubic zirconia (or CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO4). It is sometimes erroneously called "cubic zirconium".

Because of its low cost, durability, and close visual likeness to diamond, synthetic cubic zirconia has remained the most gemologically and economically important competitor for diamonds since 1976. It is marketed under brand names such as "Tru-Diamonds". Its main competition as a synthetic gemstone is the more recently cultivated material, synthetic moissanite.

Cubic zirconia is crystallographically isometric, an important attribute of a would-be diamond simulant. During synthesis zirconium oxide would naturally form monoclinic crystals, its stable form under normal atmospheric conditions. A stabilizer is required for cubic crystals to form, and remain stable at ordinary temperatures; this may be typically either yttrium or calcium oxide, the amount of stabilizer used depending on the many recipes of individual manufacturers. Therefore the physical and optical properties of synthesized CZ vary, all values being ranges.

It is a dense substance, with a specific gravity between 5.6 and 6.0 — at least 1.6 times that of diamond. Cubic zirconia is relatively hard, at about 8 on the Mohs scale— slightly harder than most semi-precious natural gems. Its refractive index is high at 2.15–2.18 (B-G interval, compared to 2.42 for diamonds) and its luster is adamantine. Its dispersion is very high at 0.058–0.066, exceeding that of diamond (0.044). Cubic zirconia has no cleavage and exhibits a conchoidal fracture. Because of its high hardness, it is generally considered brittle.

Under shortwave UV cubic zirconia typically fluoresces a yellow, greenish yellow or "beige". Under longwave UV the effect is greatly diminished, with a whitish glow sometimes being seen. Colored stones may show a strong, complex rare earth absorption spectrum.

There are a few key features of cubic zirconia which distinguish it from a diamond:

Dispersion: With a dispersive power greater than diamond (0.060 vs. 0.044) the fire of cubic zirconia is more prismatic.

Hardness: Cubic zirconia has a rating of approximately 8 on Mohs hardness scale vs. a rating of 10 for diamonds.

Specific gravity: a cubic zirconia will weigh about 1.7 times more than a diamond of the same size.

Flaws: Contemporary production of cubic zirconia is virtually flawless, whereas most diamonds have some sort of defect, be it a feather, included crystal, or perhaps a remnant of an original crystal face (e.g. trigons).

Refractive index: Cubic zirconia has a refractive index of 2.176, compared to a diamond's 2.417.

Cut: Some cubic zirconia gemstones are cut with facet shapes which differ from those typically used for diamonds. This difference would be visible under close inspection with a loupe.

Color (or more precisely, the lack thereof): Only the rarest of diamonds are truly colorless, most having a tinge of yellow or brown to some extent. By comparison, cubic zirconia can be made in most cases entirely colorless: equivalent to aperfect "D" on diamond's color grading scale.

Thermal conductivity: Cubic zirconias are thermal insulators while diamonds are among the most efficient thermal conductors, exceeding copper. This makes telling the difference between diamond and cubic zirconia quite easy for those with the right instruments.
