Diamond
Heera · Vajra
Diamond is crystalline carbon with exceptional hardness, high refractive index and strong dispersion. Hardness describes resistance to scratching, not freedom from chipping, so cut and setting remain important.

Colour
Colour is a range, not a shorthand.
Diamonds range from colourless through yellow and brown to less common hues including pink, blue and green. Body colour, cutting and lighting all affect face-up appearance.
Clarity and character
Read inclusions in context.
Internal features and surface characteristics are described as inclusions and blemishes. Their type, position and relief matter more to durability and appearance than a grade considered in isolation.
Treatment disclosure
Ask what changed and how it was detected.
High pressure and high temperature processing, irradiation, annealing, laser drilling and fracture filling may alter colour or apparent clarity. Natural or laboratory-grown origin, detectable treatment and report details should be stated separately.
Setting practice
The mount answers the material.
Protect vulnerable points and girdle areas, especially on corners. The seat should support the stone evenly without forcing it, and the setting must remain accessible for inspection.
Care
Care follows the individual record.
Warm water, mild soap and a soft brush suit many untreated diamonds, but a treatment record can change the recommendation. Avoid hard knocks and ask before steam or ultrasonic cleaning.
Sourcing questions
Questions worth carrying to the desk.
- 01Is the stone natural or laboratory-grown?
- 02Which treatments, if any, have been detected?
- 03Does an independent report accompany the stone?
- 04What provenance documentation is available for this individual stone?
Kundali note
In Jyotish traditions, diamond is commonly associated with Shukra. Any use within a Kundali-led commission follows a personal reading and material review. The association is cultural and does not guarantee an outcome.
Traditional association and gemological assessment remain distinct parts of a conversation. No material is presented as an outcome guarantee.
