Hot Fix Rhinestone`s Quality Review Rhinestone quality from brightness, cut, uniformity, glue fastness three determined.
1.Appearance
First
look hot drilling cutting surface, cutting surface, the higher his
diopter, better brightness, and secondly, the cutting surface is
uniform, there is gnashing of teeth, scratches, bubbles are deemed
defective. Hot
drilling process demanding, complex process, the yield is not very
high, the defect rate of 3% -5% of the diamonds should be regarded as a
good product, and then look at the size of the diamond are the same. SS6 numbers in diameter 1.9-2.1mm, SS10 numbers in 2.7-2.9mm .... Also should look at the thickness is consistent.
2.Adhesive
Look at the color of diamonds over the back of gum, the color is uniform, not shades. Brightly colored uniform, seen as a good diamond.
3.Firm
Rhinestone glue on the back of higher solubility, fastness diamonds as possible. The best way to identify diamonds: hot on the washing machine after a
good wash, washing can not afford to prove fastness, washed it off, not
to prove firmness of glue, a good product does not dry out.
Common grade

Class
A: brightness, there are few variegated diamond cutting surface uneven
teeth, scratches, bubbles, defective rate of 5% -8%, unglued end
probability of 1% -2%, consistent with the size of the diamond, strong high.
