can color treated diamonds be fracture filled / laser drilled?

[lasugar]

Like or would the color treatment mess with the clarity treatment?

I dunno
what do u guys think?
Can the diamond have its cake and eat it too?
Yummmmmm

thanks

Short answer is yes, definitely. Although the heat generated by irradiation treatment may be enough to cause the high lead glass filler to break down or leak out of fractures. This would certainly happen if the diamond is subsequently annealed to change it''s color from green to yellow. If the fracture filling treatment happens after the color treatment then it would be unaffected and both treatments could coexist quite well. Laser drilling would be unaffected by color treatment.

I hope this help, and good luck.

so I have now learned that farcture filling gets rid of those feathers, and laser drilling removes those ugly black lines and spots
great! lol


Like still I havent found a way to color a diamond white. can you with color treatment? I dont think it can be done, or can it?

Something like 1 to 2 percent of diamonds can possibly be turned from brown tints to colorless and near colorless by high temperature and high pressure treatment. They are sold by LKI as Bellataire and I suppose sold by others with possibly less disclosure of treatment. I have seen many large HTHP diamonds and they were fine looking examples. You won''t find them with lots of imperfections as they''d break during the HTHP treatment. I have not ever seen one laser drilled, but I am sure it could be done although those type of inclusions usually dictate no HTHP will be attempted.
