Betzalel Ambar, affectionately known as "Bez," is the visionary owner and driving force behind the esteemed jewelry company, Bez Ambar Inc., nestled in the heart of downtown Los Angeles, California. He rose to prominence in 1982 with his groundbreaking invention of the Quadrillion® cut, which has since become synonymous with the immensely popular Princess-cut diamond. With a successful career spanning over four decades, Bez has left a significant mark on the jewelry industry through his innovative diamond cutting techniques and setting craftsmanship. His extensive experience is evident in each meticulously crafted piece, showcasing skillful precision with an artistic touch.


Introducing the visionary Bez Ambar, who, in 1979, relocated to Los Angeles, California and founded the esteemed Ambar Diamonds Inc., a prestigious and highly sought-after purveyor of fine jewelry.

In 1982, Bez unveiled his labor of love: the Quadrillion® cut, now synonymous with the world-renowned Princess-cut diamond, a highly coveted style. With a solid background in the diamond cutting business, Bez shifted the company's focus towards jewelry design and distribution. A sample ring exhibiting the Quadrillion® cut heralded this transformation, subsequently propelling Ambar Diamonds Inc. to global recognition as a premier jewelry design firm. In 1985, the company received the distinguished DeBeers Award for the ATW Quadrillion® ring, an accolade honoring its achievements in the diamond industry.

Bez Ambar's innovative spirit continued to flourish in 1988, when he introduced the Laserset®, a rimless and prongless setting for square-cut diamonds. In 1992, he unveiled the "Boundless" setting, a comparable concept adapted for round diamonds.

Bez's unwavering dedication to innovation culminated in the creation of the Pavé setting in 1999, now known as the Micro-Pavé setting. His trailblazing contributions to the industry also encompass the Blaze® cut diamond in 2003 and the round Divine Cut® in 2015. Diamond connoisseurs frequently describe the scintillating appearance of a gemstone under white light as "Fire" or "Diamond Fire." This dazzling effect arises when light disperses into a spectrum due to each color traveling at distinct speeds, producing the mesmerizing visual phenomenon known as dispersion.

Diamond Cuts

Quadrillion® Cut

In 1982, The Quadrillion® cut was introduced to the world. Also known as the Princess cut, the Quadrillion® cut differs from other Princess cuts sold on the market today in the sense where they’re mostly cut for weight retention, whereas Bez’s, along with his fellow designers and partners, Israel Itzkowitz and Ygal Perlman, created a 49-facet square-cut design that accentuates brilliance without having its corners cut. Before the Princess cut was invented, most square cut-shaped diamonds were snipped along the 90-degree corners which kept the stones from having an overall luminosity.

Blaze® Cut

In 2003, Bez Ambar unveiled the Blaze® cut. The most distinctive feature of this new cut are the burst of colors it produces through its 9 crown (top) facets. The Blaze cut is a square cut diamond with 13 facets; 9 crown facets and 4 pavilion. There are 3 properties in a diamond that make it one of the most highly sought after gemstones; brilliance, scintillation, and dispersion, otherwise known as fire. Bez designed the Blaze cut to maximize a diamond's dispersion. Bez Ambar believes that the most beautiful property of a diamond is its ability diffuse white light into the multitude of colors that make up the visible spectrum. The larger facets of the Blaze® cut create a greater opportunity for the light to be broken up and therefore dispersers a fire 10 times larger than any other cut of the same size.

Divine® Cut

Unveiled in 2015, the Divine® Cut is Ambar’s latest creation. Like his previous cut, Ambar was awarded an international design patent, for the Divine® cut. After his previous accomplishments in square diamond cuts, Bez shifted his attention to round cuts with the aspiration to recreate the fire and beauty of a Blaze Cut in a round shape. The traditional round brilliant cut has 58 facets, while the divine cut has only 46, 22 crown facets and 24 lower pavilion facets. With this decrease of facets on the crown comes an increase in the size of Fire.

Diamond Settings

In 1988 Bez Ambar created the invisible setting for square cut diamonds. The idea came from the designer’s ambition to set diamonds without showing any of the metal that would traditionally interrupt the continuity of a piece’s brilliance. To make sure that no metal shows, Ambar created a petite and delicate groove under the girdle of the diamond with a laser and microscope to maintain his well-known precision. Using these groves Bez could hide any metal that would be seen in the more traditional settings.

In 1992, Bez Ambar invented and patented the "Boundless" setting. The "Boundless" setting allowed for invisibly set round diamonds. Using a technique similar to his invisible setting for square stones, Bez was able to omit the prongs or rims used to set round stones.


In 1999, Bez Ambar added an additional achievement to his already-extraordinary list, with what we know today as the Micro-Pavé setting. This impressive discovery changed the game in the jewelry industry. The concept entails using a microscope to graft thousands of microscopic stones in his Pavé settings onto a one-piece with sheer precision. The end result is a captivating design.
