Learn About Natural Gemstones

Zarkaar™ — The Art of Precious Stones

At Zarkaar, every piece of jewellery is crafted with intention. Central to our craft are the natural and lab-grown gemstones we carefully select — each chosen for its brilliance, durability, and beauty.

This guide will help you understand the gemstones we use, how they are graded, and how to care for them.

What Are Natural Gemstones?

Natural gemstones are minerals, rocks, or organic materials that are formed within the Earth over thousands to millions of years. They are then cut, polished, and set into fine jewellery.

Key characteristics of a gemstone include:

Beauty — visual appeal, color, and brilliance
Durability — resistance to scratching and wear
Rarity — how scarce the stone is in nature

Gemstones Used by Zarkaar

💎 Moissanite

Moissanite is one of the most brilliant gemstones in the world — even more brilliant than a diamond. Originally discovered in a meteor crater, it is now ethically lab-grown.

Hardness: 9.25 on the Mohs scale
Brilliance: Higher refractive index than diamond
Appearance: Near-colorless to colorless
Why we use it: Exceptional sparkle, ethical sourcing, and outstanding value

🔵 Blue Sapphire

Sapphires are among the most prized gemstones in the world, known for their deep, velvety blue color and remarkable hardness.

Hardness: 9 on the Mohs scale
Color: Deep blue to cornflower blue
Symbolism: Loyalty, wisdom, and nobility

🟢 Emerald

Emeralds are a variety of beryl and are celebrated for their rich green color. They are one of the four precious gemstones alongside diamonds, rubies, and sapphires.

Hardness: 7.5–8 on the Mohs scale
Color: Vivid green
Symbolism: Growth, renewal, and prosperity

🔴 Ruby

Rubies are one of the most valuable gemstones, prized for their intense red color and exceptional hardness.

Hardness: 9 on the Mohs scale
Color: Deep red to pinkish-red
Symbolism: Passion, courage, and love

⚪ White Topaz & Cubic Zirconia

Used in select designs as accent stones, these offer excellent clarity and brilliance at an accessible price point.

How Gemstones Are Graded

Gemstones are evaluated using the 4 Cs:

Cut — The shape and faceting that determines how light reflects
Color — The hue, tone, and saturation of the stone
Clarity — The presence or absence of inclusions and blemishes
Carat — The weight of the gemstone

At Zarkaar, we source stones that meet high standards across all four criteria to ensure every piece is worthy of being called luxury.

Caring for Your Gemstone Jewellery

To keep your gemstones looking their best:

Store jewellery in a soft pouch or lined box to prevent scratching
Avoid exposure to harsh chemicals, perfumes, and cleaning agents
Remove jewellery before swimming, exercising, or sleeping
Clean gently with a soft cloth and mild soapy water
Bring your piece to us for professional polishing and replating when needed

Why Zarkaar Chooses Quality Stones

We believe that true luxury lies in the details. Every gemstone we select is chosen not just for its appearance, but for its ethical sourcing, durability, and long-term brilliance. Our jewellery is crafted to be passed down — a legacy in every stone.
