Carat

Carat measures a diamond’s weight, with one carat equaling 0.2 grams. While larger diamonds are generally more valuable, two diamonds of equal carat weight can vary significantly in price due to other factors. Carat weight has a non-linear relationship with price; as size increases, per-carat price often rises exponentially.

Cut

A diamond cut, ranging from Excellent to Poor, determines how well it interacts with light, affecting its brilliance, fire, and scintillation. An excellent cut can make a diamond appear larger and more brilliant, often commanding a premium over poorly cut stones of the same carat weight.

Clarity

Clarity grades, from Flawless (FL) to Included (I3), indicate the presence and visibility of internal (inclusions) or external (blemishes) characteristics. Higher clarity grades typically correlate with higher values, though differences between top grades may be indistinguishable to the naked eye.

Color

Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). Colorless diamonds (D-F) are the most valuable in the white diamond range, with prices decreasing as color becomes more noticeable. However, certain fancy-colored diamonds can be extremely valuable due to their rarity.

Certifications

Diamond grading reports from respected laboratories like GIA, AGS, or IGI provide unbiased assessments of a diamond’s quality. These certifications enhance a diamond’s value by verifying its characteristics and ensuring buyer confidence. GIA certificates, in particular, are widely regarded as the industry standard.

How Much is a Diamond Worth?

A diamond’s worth is determined by a complex interplay of the 4Cs, market demand, and rarity. While the 4Cs provide a baseline for valuation, factors like fluorescence, market trends, and even geopolitical events can influence prices.

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you’re buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.

Nissan, David and his team were extremely accommodating, understanding and patient with our purchase. They took the upmost care to find the best solution for our needs and went above and beyond normal ‘customer service’ standards. I have absolutely no qualms recommending their products and services. Both were absolutely flawless. I will continue to sing them praises and will most definitely purchase from them again in the future. Thank you again!

Color

Think of diamond color like this: D is ice-clear, and as you go down the alphabet, a tiny bit of yellow creeps in. But here’s the thing – most people can’t spot the difference between a D and an H, especially in a ring. An I or J can look just as white and save you a bunch of cash. Don’t stress about getting the “perfect” color. Focus on what looks good to your eye and fits your budget. Sometimes, a little warmth in a diamond can even be pretty cool.

Clarity

Diamond clarity is about tiny flaws, but don’t sweat the perfect grade. Most diamonds have these little quirks, but what counts is whether you can see them without a magnifying glass. Go for “eye-clean” – it looks flawless to you and costs less than those top grades. Some tiny marks can even prove it’s real. Trust your eyes, not just the certificate. You’re buying a diamond to admire, not to put under a microscope!
