What Influences 3 Carat Lab Grown Diamond Prices?
Price of a 3 Carat Lab Grown Diamond several factors…. These include:
Shape:
Shape is a prime factor determining the price of the diamond. This high demand is reinforced by large numbers of buyers, a terrific marketing system whereby the diamond retailer persuades a much bigger proportion of customers to buy these overpriced piles of crystallins (as mentioned above), and, most importantly, the relatively low expense cost that jewellers have had in selling these stones.
This last factor combined with round’s dominance within both men’s jewellery and women’s fashion has gradually been reducing their list price so as to enable lower-cost providers who focus on exactly the kinds of people that are likely to appreciate them.
At the same time, princess cuts usually represent much more bang for your buck while still delivering comparable sparkle.
Clarity
You can find lab-grown diamonds in differing clarity grades from FL (flawless) to I (included). VS1 and VS2 clarity diamonds are popular among buyers as they strike an excellent balance between cost and look.
Color
Another aspect of the diamond is the shading. However, the most common selection for a 3 carat diamond is F-color, which means it appears near colorless and offers outstanding brilliance without the premium cost of D or E grades.
Cut
Determines the sparkle of the diamond with cut quality. A large diamond that is of good clarity but poorly cut will have a dull appearance. You would want to avoid any cut ratings under Excellent or Very Good for optimal brilliance.
| Diamond Shape | Price (USD) | Popularity (%) |
|---|---|---|
| Round | $1,622 | 35% |
| Oval | $2,134 | 20% |
| Princess | $1,760 | 15% |
| Cushion | $1,878 | 10% |
| Pear | $1,987 | 8% |
| Radiant | $2,115 | 5% |
| Emerald | $1,779 | 4% |
| Heart | $2,067 | 2% |
