Red Ruby

Red Ruby Heated 0.27 CT 5x3mm From Mozambique. 

A ruby is a precious, blood-red to purplish-red gemstone made of the mineral corundum. Highly valued for their durability (9 on the Mohs scale) and fiery color, premium rubies (like Burmese "Pigeon's Blood" and Mozambique "Crimson Red") are rarer than diamonds. 

Rubies are priced and evaluated based on a few key factors:

• • Color: The most sought-after hues are deep, saturated reds. Traces of chromium give the stone its iconic glow. 

• Treatments: Many natural rubies contain internal fractures. It is common (and accepted) for stones to undergo heat treatment to improve color, or to have their surface fractures filled with glass. 
• Origin: Stones are famously sourced from Myanmar, Thailand, India, and Africa. 
• Value: Prices range from roughly $300 for smaller or treated stones up to tens of thousands of dollars for certified, unheated, and flawless gems.
