Treated Diamonds

Treated Diamonds.

Treated Diamonds started when the Diamonds industry started, many color and clarity treatments were done to ¨improve¨ Diamonds defects in order to increase their value and attractiveness.

The Color Enhancement originally started with a simple coat (a thin layer of chemicals or plastic) that enhance the Diamond color, With time an technology advances a new color enhancement started called Irradiation, which is a permanent color change ( using radiation).

Now a days the most common color treatment is HPHT which stands for High Pressure High Temperature, in the 1990s scientists discovered that using High Pressure combined with High Temperature (similar conditions to the Diamond formation) can result in making certain low color Diamonds Pink, Blue, Green and Yellow, and most commonly Broun to Colorless.

With time a few clarity enhancement techniques started to appear in the market the most common once being LD and fracture filling.

LD stands for Laser Drilling, which is a treatment used to remove dark inclusions, by making a hole from the Diamond surface to the dark inclusion in order to burn it, the treatment leaves a tiny drill hole (can be spotted with a loup, a tub is seen from the Diamond surface to the center, or by looking at the facets carefully searching for an opening in one of them).

LD can be done in any part of the Diamond, however the most common once are inserted from the Diamonds Table all the way to the dark carbon.

Fracture filling is a treatment done by injecting molten glass substance into a visible fracture in a Diamond, this treatment is very effective for the Diamond clarity, however many routine cleaning methods can damage the treatment.

 Treated Diamonds MUST be sold with disclosure of the treatment, it is illegal to sell treated Diamonds without it.

 Buying treated diamond is like buying gold filled jewelry, it looks good but not recommended.

Treated Diamonds are never ever ever an investment in any way.
