Weight (Specific Gravity): Standard Diamond Density – 3.52. Like all diamonds, it has a high specific gravity for a gemstone, contributing to its notable “heft.”
Treatment: Blue diamonds are frequently treated to enhance their color. Common treatments include:
HPHT (High Pressure High Temperature): Can turn certain grayish or brownish diamonds a more desirable blue.
Irradiation + Annealing: Creates or intensifies blue color.
Coating: A thin layer of synthetic blue diamond or other material may be applied.
Natural, untreated blue diamonds (like the famous Hope Diamond) command the highest premiums and require laboratory certification to confirm origin.
Body (Clarity/Transparency): Blue diamonds range from Flawless to Included (I1-I3). The color can sometimes mask inclusions. They possess the supreme adamantine luster and exceptional transparency of diamond, with a perfect octahedral cleavage and the highest possible rating of 10 on the Mohs scale.
