Diamond Prices Explained

Diamonds for Sale: Wholesale Prices for Top Quality Gems 9

While diamonds are difficult to price, there is a way to determine the wholesale value of diamonds.

There are several factors that influence prices for diamonds:

– diamond carat weight or size

– cut and shape of diamonds

– clarity grade/clarity level (SI, VS)

The better these qualities in your diamond, the higher its retail value will be. However if you purchase from reputable sellers then they should have already taken into consideration all three criteria when pricing their diamonds. Therefor it is important not to try and compare prices between different stores as each has an individual set cost based on quality vs selling price which could vary drastically even within one store depending what gems currently have available for sale.

Cut and shape of diamonds

examples of different diamond cuts and shapes
Diamonds for Sale: Wholesale Prices for Top Quality Gems 11

The diamonds you are looking to purchase for your engagement ring should be cut into a traditional round brilliant shape, which is the most preferred style. They can also be oval, pear shaped or emerald depending on what look best suits your personal preferences and budget.

The brilliant round is cut in order to maximize the amount of brilliance and sparkle they emit. The more brilliant a diamond is, the greater its value will be. Diamonds that have been cut with less precision won’t come out as bright or vibrant when on display – but diamonds that are extremely well-cut can make up for it by showing off their fire over their clarity instead.

That means if you find a diamond for sale with an exceptional shape but lower grades for things like clarity and color, it may have some hidden potential!

Clarity grade/clarity level (SI, VS)

chart explaining diamond clarity grades
https://www.gemsociety.org/article/gia-gem-clarity-grading-codes/

When diamonds for sale are evaluated for their clarity, it is done by assessing the number of blemishes and internal flaws like feathers and needles. SI diamonds have more inclusions than VS diamonds which could be difficult to see with the naked eye. As such, they’re less expensive per carat as there’s less demand for them but still highly sought after if you can find one without too many visible flaws.

It all depends on what budget you need to stick with. Take into account that even minor imperfections like an inclusion at the edge of a diamond may not always be reflected accurately through pictures (especially since white diamonds reflect light so well).

This means that before making any purchase, we recommend that you consider diamonds with a clarity grade of SI2 to VVS if your budget allows it. It may be better in some cases to buy diamonds for sale which are slightly smaller but have more flawless qualities than a larger stone that may look duller under further inspection and assessment after being set into your ring design.

What is the Diamond Price Chart?

The diamond pricing chart is based on diamonds that have been graded by the GIA (Gemological Institute of America). Although diamonds come in a variety of shapes and sizes, these stones all fall into one of two categories: round or fancy. The price of diamonds for sale will differ largely depending on the shape.

The price scale also depends solely on carat weight with prices increasing exponentially as the size gets larger. For example, a 0.99ct stone will be worth more than twice as much as half a carat diamond but four times as valuable if it weighs exactly one full carat instead of just under.

This makes diamonds an excellent investment for those looking to make their money go further because each purchase can become increasingly profitable over time without any extra effort from you!
