The traditional definition of "Precious Stones" includes only four primary gems: **Diamond, Ruby, Sapphire, and Emerald.** These four are historically and commercially classified as precious due to their rarity, exceptional hardness, unique chemical composition, and high desirability throughout history.

All other gems, such as amethyst, topaz, peridot, and turquoise (Feroza), are categorized as semi-precious stones. At Raza Gems, we focus on the precious stones, ensuring every stone meets investment-grade quality.

The worth of a precious stone is determined by a globally recognized grading standard centered on the **4 Cs: Carat Weight, Cut Quality, Color Saturation, and Clarity (inclusions)**.

• **Carat Weight:** The size of the stone.
• **Color:** The intensity and purity of the hue (e.g., a "Pigeon's Blood" Ruby commands a premium).
• **Clarity:** The absence of internal flaws (inclusions).
• **Cut:** The precision of the facets, which determines how the stone handles light and brilliance.

Furthermore, **Certification** from a reputable lab (like IDL, GIA, or IGI) is mandatory for accurately determining value, as it authenticates the stone's type, origin, and lack of artificial treatments. Our **precious stone price in Dubai** reflects this detailed grading process.

Precious stones are formed deep within the Earth's crust over millions of years under immense heat and pressure:

• **Diamonds** crystallize from pure carbon under extreme pressure (over 150 km below the surface).
• **Corundum** (Rubies and Sapphires) forms in specific metamorphic and igneous rocks when aluminum oxide is present, often with trace elements.
• **Emeralds** (Beryl) form when hydrothermal veins carry beryllium and chromium.

The precise geological environment is what makes certain origins (like Sri Lanka for Sapphire, or Colombia for Emerald) highly prized and valuable.

Precious stones are found in specific geographical regions globally. Raza Gems sources directly from these regions, including:

• **Diamonds:** South Africa, Botswana, Russia, and Australia.
• **Rubies:** Myanmar (Burma), Thailand, and Mozambique.
• **Sapphires:** Sri Lanka (Ceylon), Kashmir, and Madagascar.
• **Emeralds:** Colombia, Zambia, and Brazil.

We leverage our central location in the UAE to ensure an ethically transparent supply chain from these world-renowned mining regions.
