Israeli born, Betzalel Ambar, known to many as “Bez”, is the owner and operator of the prestigious jewelry company, Bez Ambar Inc., located in Downtown Los Angeles, California. His claim to fame is for his 1982 invention of the Quadrillion® cut, which is most notably known as the popular Princess-cut diamond. Bez has had great success with his innovative diamond-cutting and setting work in the jewelry industry for over four decades. His longtime experience shows in his work, where each piece is made with fine precision with an artistic flair.

Meet Bez Ambar. Who in 1979, moved to Los Angeles, California. There, he opened and established Ambar Diamonds Inc., the go-to, high-end, fine jewelry company.

In 1982, he revealed his five-year invention of the Quadrillion® cut, better known as the world-famous Princess-cut diamond, and one of the most popular diamond styles on the market.

Bez was well-connected to the Israel Diamond Exchange, and what started out as a diamond distribution business, the focus shifted onto jewelry design and distribution where a sample ring was created to showcase what is now known as the Quadrillion® cut. From that point on, and with much success, Ambar Diamonds Inc. quickly emerged as a world-renown jewelry design company. In 1985, Ambar Diamonds went on to win the highest of achievements in the diamond world and received a DeBeers Award for his ATW Quadrillion® ring.

With continued success, in 1988, Bez Ambar gained notoriety yet again with his rimless, prongless setting for square-cut diamonds with the creation of the invisible setting setting known as Laserset®, and in 1992, he introduced a similar version called “Boundless”, which he invented for round diamonds.

In 1999, Bez’s innovations continued with the invention of the Pavé setting, which we now know as the Micro-Pavé setting, and his other brainchildren which included the Blaze® cut diamond in 2003, and the round Divine Cut® cut in 2015. Known to diamond aficionados as Fire or Diamond Fire, is when a stone is exposed to white light, each of its colors travels at different speeds which then separates the colors into a spectrum. This is called dispersion, and that’s what gives it that fiery look.

With God-given talent and jewelry design ingrained in his blood, In 1995, Bez Ambar went on to win the prestigious De Beers Award for his ATW Quadrillion® ring for both its ingenuity and innovation.

A millennium is such a rare occurrence. Many of us were here to witness this unique time and to celebrate this special lifetime event, Mr. Ambar created and welcomed the Millennium Necklace. This gorgeous choker-style necklace was designed using Bez’s invisible setting, also known as Laserset®, along with a thousand of his patented, Quadrillion® cut diamonds that were set into four, flawless, dazzling rows.

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.

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.

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.

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.
