What Differentiates Benzgem from other Imitations & Simulants?

  1. Unlike the Others, Benzgem's Color is in the rough; it is not an amorphous coating or plating. The rough is a Realistic White, tinted in the G-H-I-J Color Range - THE Color of 95.% of all Natural Mined Diamonds
  2. 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 are.
  3. Like all Genuine Natural Diamonds, each Benzgem is Singly Refractive, and therefore, Sparkle like Natural Diamonds. Benzgem's luster, like diamond, is Adamantine, Benzgem is Tough, its Hardness is below 9.00 (Mohs hardness rating for a steel hammer is 6.50. Diamonds can cut into a steel hammer, but a hammer is Tough and can crush a diamond. Do not confuse Hardness with Toughness. Moissanite and Diamond can both fracture)..
  4. Innovative, Exquisite, and Exclusive, Benzgem is THE closest to any Genuine Mined Diamond available on the market

What are the Benefits of owning a Benzgem?

  1. Benzgem was created Exclusively by GuyDesign® for the sole purpose of being the Most Believable and Realistic Alternative to a Mined Diamond.
  2. You will Feel and Experience the Opulence of wearing a Genuine, Natural, Mined "Rock"


Love the sparkle, but what is the Advantage of Benzgem's G-H-I-J Color?

  • The main advantage is the Natural and Believable Diamond look it imparts.
  • Benzgem's G-H-I-J Color Range Jewels remain the same color whether indoors or out. No Fluorescence.




  • Other diamond simulations are unrealistic in their Underlying Body Color. Colorless Cubic Zirconia is two or more shades Whiter than the Whitest Diamond grade of "D", Colorless.
    "D" is the Top Level of White occuring 1 in every 100000 Carats of Genuine Diamonds.
    Cz's in the Marketplace, on the other hand, are the Best color attainable, comparable to the Rarified Type IIa Diamond color. Cz's body color contains no yellow, [Natural Coloring Agent found in a Genuine Diamond] therefore exhibits an artificial bluish Glow in Sunshine and under Flourescent Lighting...A very unrealistic body Color.
  • Moissanite's body color, on the other hand, is too green or too yellow and is Doubly Refractive, unlike Diamond.

Photo of a Very Large Moissanite. Notice the Overall Blurred appearance of this stone. This is double refraction in action. Diamonds, Most Imitation Diamonds, Russian Formula Fianit and Glass, are all Singly refractive, thus more Diamond like.





I already own Diamonds. How do I know Benzgem will Match what I already have?

  • I Guarantee it... Benzgem's G-H-I-J Color Grade, is both Natural and Believable.
  • It's color will match and coordinate with the Diamond Jewelry you already own.
  • Benzgem's Clarity is SI1 [clean to the naked eye] or better.


That all sounds well and good, what if I need ring sizing or repair?

  • Benzgem combined with our Natural Diamond Semi-mount is completely serviceable.
  • Sizing and any repair work can be performed without removing all of the diamonds in the Semi Mount.
  • Removal of stones is standard procedure, as a result, most Artificial Diamond jewelry remain unused and in a state of disrepair.


I've noticed the Use of Genuine Natural Diamond Semi-Mount, why is this so?

  • We believe the Most Believable Fake Diamond in the world is so deserving of a Genuine Natural Diamond Semi-Mount.
  • This arrangement will Satisfy Your Desire for a Natural Mined Diamond with the added benefit of not having to wait for that Great Big Dream Diamond You've always wanted. It really is a small price to pay for a Dream Come True.
  • In the future should you grow out of Your Benzgem, your Genuine Diamond Semi-Mount, like all diamond jewelry, has a resale value. Sounds like a win to me!


Is there a Sample available?

  • This Jewel is too Expensive to give away as a free Sample. Please see the top of this Store Page for BENZGEM SAMPLE. You will find all that You request, here.


I've noticed Made to Order Jewelry Available for Purchase but did not see a Loose Stone Purchase Option; Are Loose Stones available for Purchase?

  • Due to high demand, we are giving this request special consideration.
  • Allowing them for purchase Loose was not our intention as our Benzgem by GuyDesign® Jewels are very special.
  • The Individual Jewel stones are very pricey alone. Our Wish was to create beautiful Fantasy Jewelry for You, Dream Jewelry actually.

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.

    I have the Simplest tastes... I am always Satisfied with the Best

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.

Most Designs, if not All Jewelry will accommodate the following Diamond and Gemstone Shapes:

Genuine Diamond Semi-Mount Options:

Our Semi-Mount Diamonds are the Very Best, Precise Fully Faceted Cuts - No Diamond "CHIPS" here!

  1. Our recommended minimum - GIA Grade G-H Color - These diamonds are "Near Colorless" and will appear "White" face up.
  2. Our recommended minimum - GIA Grade SI1 Clarity - these diamonds are Slightly included and will appear Clean and Transparent to the unaided EYE.
  3. Upgrade - GIA Grade G+ Color - These diamonds are "Near Colorless" and will appear "White" face up.
  4. Upgrade - GIA VS Clarity - These diamonds are Very Slightly included and will appear Clean and Transparent to the unaided EYE.

Gemstones come in all Sizes, Types and Colors.
