Diamond Clarity Enhancement Service
Certain included diamonds can be processed for clarity enhancement to produce a much better-looking diamond. Such enhancement is a cosmetic process and does not alter the other characteristics of a diamond.


Laser Drilling and Fracture Fill

Before Enhancement
After Enhancement

The representative photo above shows some visible inclusions in a natural diamond. Such inclusions can be filled up with transparent material with refractive index close to that of natural diamond. This diminishes the visible inclusions in a diamond and produces a better-looking diamond. Drilling microscopic tunnel and then injecting solvents to dissolve or bleach the inclusions is used to reduce or eliminate black carbon inclusions. Please refer to the FAQs section to understand which diamonds are suitable for this enhancement.


Procedure and Pricing
Submit the diamonds to be clarity enhanced to our office in New York City. Our in-house experts will inspect the diamonds to determine suitability of diamond for clarity enhancement. The expected results will be communicated to the client. At this point we require clients final approval and acceptance of our terms to process the diamond.

On client's approval, the diamond is submitted to our lab for clarity enhancement. This process takes 7 to 10 business days. The diamond is returned to the client as soon as it is ready.

To send a diamond for processing please ship it to our New York address. Please contact a representative by phone, email or web before sending the diamonds. A local resident can set up an appointment and come in personally to submit the diamond for processing.

Pricing for the clarity enhancement depends on the specific needs. It is determined based on clarity enhancement procedure necessary, size of the diamond submitted, total number of diamonds submitted, etc. Please contact our representative to get quotes for processing.



Quality Assurance
Through several years of scientific and empirical studies, our labs have been able to develop sophisticated and well-controlled processes for diamond clarity enhancement. Our clarity enhancement improves the looks of the diamond without altering any other characteristic of the original diamond. After our process you get absolutely the same diamond sans the visible inclusions and there is no change in weight.
