Know the difference between Diamond, Moissanite and Cubic Zirconia and what are they worth.

Diamond is an exceptionally precious stone made up of pure carbon’s crystalline form. This is the hardest substance known to us which is naturally formed under immense temperatures and pressures on earth. A fascinating fact is that diamonds can take 1-3 billion years to form deep down the earth’s surface, no wonder why they are so beautiful and expensive.

With the advancements in modern technology, we can also mimic the High-Pressure-High-Temperature (HPHT) conditions in a laboratory to make Synthetic Diamonds which have exactly the same or even better physical properties than the authentic diamonds. Although cheaper, lab-grown diamonds are not as popular as the real ones – with incomparable rarity.

Moissanite is one of the most popular substitutes for diamonds. A rare mineral, Moissanite exhibits excellent optical properties and shines even brighter than a real diamond. Often discovered in meteor craters, this type of gemstone is second only to diamonds in terms of hardness and durability. Moissanites are also being grown in labs and are considerably cheaper than diamonds.

Cubic Zirconia (CZ) is a man-made crystalline material which simulates a diamond’s hardness and brilliance. CZ is very affordable and is used to make inexpensive jewelry to mock a diamond’s visual appeal. With an untrained naked eye, telling the difference between a cubic zirconia and a diamond is quite difficult. But again, these are not rare and nowhere near to match the pricelessness and beauty of real diamonds.










• Price per carat is around ₹5,000 to ₹20,000

• Also sold after considering factors like color, size and cut etc.

• Lasts forever, generally no need of replacement

• Surprisingly, many Moissanites are even brighter than diamonds with better Fire Dispersion

• Less harder than diamonds, but still very hard to match diamonds

• Moissanites weight less than diamonds, but can confuse diamond testing machines due to better scintillation and hardness properties


• Price per carat can be around ₹50,000 to as high as ₹10,00,00,000

• Value depends on the rarity, uniqueness and historic value

• Lasts throughout the ages and passed down to future generations

• Bright enough to shine through the dirt

• Hardest natural substance 

• Needs highly specialized training to evaluate characteristics and price

Cubic Zirconia

• Price per carat can be as low as ₹500

• Generally not sold by carat weight and it is easily available in the market

• Commonly used in artificial jewelry 

• Fades away with scratches and normal wear over years of usage

• Very hard, but less harder than Moissanites

• Synthetic material, always man-made
