Tension Remove  Process

This process helps in reducing the stress (Tension) from the CVD diamond block. The damage caused to the CVD diamonds during shaping, laser sawing, and polishing can be reduced by the Tension removal process.

Special process or very small diamonds at very low cost.

CVD diamonds that size from 3+ to 13- (Diamond Sorting Sieve) round and fancy shapes (Below 0.10ct) are processed with low pressure and low temperature to remove the brown colour and improve the grade of the diamond easily by 2-3 Grades.

What is diamond tension?

The internal structure of a diamond includes areas of physical stress, or tension. These areas develop naturally as the diamond forms. Tension within a diamond can be mild, moderate or extreme. The tension areas cannot be seen by the naked eye, yet they are a real source of stress to diamond cutters and manufacturers.

Procedure:

1. Examine the Setting:

   • Inspect the tension setting to understand how the diamond is held in place. Tension settings usually have a small opening or slit where the diamond is inserted.

2. Protect the Diamond:

   • Cover the diamond with a soft cloth or padding to prevent scratches or damage during the removal process. Be sure to handle the diamond with clean hands or gloves to avoid transferring oils or dirt.

3. Inspect Tension Points:

   • Identify the tension points or mechanisms that hold the diamond in place. Some tension settings use a spring-like mechanism that exerts pressure to secure the stone.

4. Release Tension Gradually:

   • Use precision tweezers or pliers to gently apply pressure to the tension points. The goal is to release the pressure holding the diamond without using excessive force.

5. Rotate and Test:

   • If possible, rotate the diamond slightly while applying gentle pressure. This may help disengage the tension mechanism. Test the diamond’s movement periodically to see if it is becoming loose.

6. Professional Assistance (Optional):

   • If you encounter difficulties or are unsure about the process, consider taking the jewelry to a professional jeweler. They have the expertise and tools to handle delicate settings.

7. Inspect After Removal:

   • Once the diamond is removed, inspect both the diamond and the tension setting for any damage. Clean the diamond if necessary, and ensure that the tension setting is in good condition.
