How does Asha compare to other diamond simulants?

Mainly due to its proprietary 'Amorphous Diamond Treatment' (ADT) that coats and infuses into its underlying CZ core, no other simulant approaches Asha in diamond-like appearance.

(Asha being prepped for the ADT process)

Here is a chart overview of the Asha as compared to other competitors products:

	Asha®	Diamond Nexus®	Russian Brilliants®
Composition	Enhanced CZ	Plain CZ	Plain CZ
Patent pending		No	No
Raman testing		No	No
Goniometry testing		No	No
XPS testing		No	No
Brilliancescope® testing		No	No
Light Analysis Testing		No	No

The ADT of Asha also offers additional hardness, toughness and scratch resistance; standard CZ is approx. 8.5 on the Mohs, Moissanite is 9.25 and the ADT of v5 Asha is 9.7-9.8 (note that the Asha itself is approx 9.0 since it is a combination of ADT and CZ). The ADT also offers enhanced luster and it gives the Asha the ability to handle light as a diamond does.

Standard CZ is somewhat porous, skin oils, soap and dirt can stick to and quickly be absorbed into the stone clouding and dulling its appearance, even within a few hours of wear. Asha’s ADT is non-porous, and with its coefficient of friction less than that of Teflon, non-stick, so skin oils, etc. are not absorbed and can be easily cleaned away.

CZ is made of thicker molecules than diamond so more light is slowed down while passing through which moves additional light from the non-visible spectrum into the visible spectrum and the first color the human eye can see is blue, and this is the reason many standard CZs have an awful bluish cast or haze. This bluish cast should not be confused with reflection, as an example: looking at a diamond or sim in sunlight on a clear day and the stone looks blue simply because it is reflecting the blue of the sky. The ADT of Asha filters out much of this additional light, giving it closer light return to that of a diamond.

CZ has less brilliance (white light return) than a diamond but more fire (colored light return) and is singly refractive, as diamond is. Moissanite has more brilliance, fire and luster than diamond but is doubly refractive (each single facet edge looks like two) which can lend a ‘fuzzy’ appearance to the stone in many lighting conditions.

Asha is also unique in that we have published the results of multiple independent lab tests (Raman, XPS and contact angle goniometry) to further show the difference our amorphous diamond treatment makes. You may wish to view the details of these tests and their results here:

Asha, with its ADT, offers what no other simulant can, a diamond-like luster and a beautiful balance of brilliance and fire.
