About Signity Star.
Signity Star is a high grade cubic
zirconia cut to
ideal standards for maximum reflection.
As noted in the dispersion
column Signity Stars are bright and sparkly and display more fire than the best grade of diamonds.
Let's review the benefits of setting a mounting with Signity Star
CZ.
First of all fire, the sparkly:
Signity Star's have more
fire than diamonds at .065 dispersion compared to
diamonds .044.
They are the most brilliant CZ on the market, second to
none.
They are amazingly white, bright and sparkly.
Why? How is this possible?
Cut:
Signity Star's excellent cut is equal to ideal cut
diamonds, the best cut for reflection.
Their cut is so accurate a star is visible through the
top of the crown with a diamond scope.
Color:
Signity Star is equal to
"D" Color of diamonds,
the whitest diamond grade.
Clarity:
Signity Star's clarity is equal to internally flawless, extremely rare
diamonds.
More
considerations.
Setting charges:
Less risk thus labor rates to set Signity Star's are less than
diamonds.
Color: Signity Star's are
whiter than most diamonds on the market as "D" color
diamonds are rare.
Most important!
Cost: Signity Star's
cost much less than diamonds.
Those are very good
reasons to use Signity Star's for accents.
Hmm?
Is this comparison fare? Probably not.
After all diamonds grade variance is extremely wide, hence, diamonds extreme grading system.
This comparison is of Signity Star's one and only grade
up against the best grade of diamond.
Perhaps that is a little unfair. To Signity Star's, that
is.

About other
accent stones we offer.
We also mount white sapphire, white topaz and moissanite.
All of these stones may have a slight tint of color as
well as most diamonds.
Only Signity Star is colorless.
White sapphire does not produce much fire at .018
dispersion but is a very hard, tough and beautiful stone that is
gaining popularity over the price of diamonds.
White topaz has a very interesting glassy clear look much
different than all of the other accents and looks very
nice next to certain center stones such as coral or deep
color stones such as lapis. Moissanite is a new man made
gem gaining popularity and has the most fire
of any of the stones above. It rarely is formed
colorless (yellow or green tint) and the cost is rather high but it's brilliance
is remarkable. |
