• Benzgem - Clearly Believable & Realistic - Guaranteed!

BENZGEM is distinguished by its Excellent Cut and Unique Color.


In absence of the Very Best Cut, there is no "Realistic Look", there is no "Believability": being hand cut is not enough, Gemstone hardness is not enough, Fine Gold and Platinum settings are not enough!

The creation of a convincing Diamond replacement, is predominantly the Stone and the Stone's Quality of Cut.

I Guarantee IT!





We Design, Hand Cut and Polish our own Jewelry Stones to the Best Diamond Quality Standards.

  • Each Jewel is handled in the same fashion as its Genuine Counterpart resulting in an eminently credible Benzgem; Designed, Hand Cut, and Polished as Real Diamonds and Gemstones are.
  • Benzgem was created Exclusively by GuyDesign® for the sole purpose of being the Most Believable and Realistic Alternative to a Mined Diamond.
  • We utilize the same Facet Designs in Use for the BEST Genuine Diamonds, we do not add facets, nor do we omit them. Side by side our Benzgem Imitation Diamond and Genuine Diamonds Look identical, Same Color and Just as Brilliant.
  • With Benzgem, You will Feel and Experience the Opulence of wearing a Genuine, Natural, Mined "Rock"

Custom Benzgem Simulated Diamond Options:

An Equally as Important Consideration is the COLOR, Our "Signature G-H-I-J Color" simulated Diamond is Guaranteed to coordinate and match the Fine Diamond jewelry you already own.

  1. Our Exclusive, Signature GIA, G-H-I-J Color Equivalent simulated Diamond, contains a hint of Yellow for the Most Believable and Realistic Look and Feel of Real.
  2. Type IIa Diamond color Equivalent if you so prefer. The Vera Krupp Asscher Cut Diamond, made popular by its celebrity owner, Elizabeth Taylor, was a Type IIa Diamond. This "Color" is much Whiter than our Signature Color, it is several shades whiter than the internationally recognzed GIA Color Grade D-E-F. Our Type IIa Diamond color Equivalent contains no yellow at all, not even a hint of yellow. This color grade is definitely rarefied in its appearance, very icy, very cold, and in the Diamond world - it is extremely Expensive.

We Manufacture our own Diamond Settings here, in the USA.

We employ American workers who Design, Cast, Polish and Set our Gemstones into the Best Diamond Quality Jewelry settings.
