1 Carat Diamond Rings

1 carat diamond rings the most popular diamond weight for natural diamonds.  The reason is probably the price point. The average price for a 1 carat center diamond ring is around $4,000 however, by cutting the middleman, handpicking affordable diamonds and working on tight margins, we are able to offer most of our 1 carat diamond rings under $2,000. Almost all of our catalog photos below were taken with a 1ct center so you can visualize the size of this diamond which is actually 6.3mm-6.5mm in diameter.

A quick guide to your 1 carat diamond ring

A diamond's carat weight is the most important of the 4 c's. The carat is a unit of weight and can actually be converted to grams at the ratio of 1 carat = 0.2 grams, do not confuse this with a karat of gold (e.g 14K) which means the purity of the gold and is unrelated to the diamond carat measurement. A 1ct diamond is usually around 6.3mm in diameter but can be smaller for a deep cut diamond or wider for a shallow cut diamond. 


A one carat diamond is probably the most popular choice of diamond size, the price of such diamonds can vary depending on their cut, color and clarity.
Diamonds are priced per carat and what is unique about them is that the price per carat increases dramatically as the size of the diamond increases.  For example a 2ct diamond would usually cost 5-6 times as much as a 1ct diamond. 


The size of the diamond (its diameter) increases as its weight increases but not at the same rate.  For example, a 1ct diamond is 6.3mm on average in diameter and a 2ct diamond is 8mm on average.  This means that for one to buy  a diamond that appears large the amount of money he would have to spend will grow exponentially.
For this reason many choose to buy a ring design that decorates the center diamond with small diamonds around it or beside it thus making the center stone look bigger with only a small increase in cost (since small diamonds are inexpensive per carat).


The dimensions of a diamond are usually measured by 3 parameters:  Width x Height x Depth.  The depth is the "height" of the diamond, the ratio between these measurements determine the cut grade.  A shallow cut diamond is bigger in diameter but shallower in its depth thus resulting in a bigger diamond for the same ct weight and a deeper cut diamond is smaller in diameter for the same ct weight.  An excellent cut diamond would have the perfect proportions.


The word carat comes from an ancient trade of gems and was called carob after a uniform seed  that was used as reference called a carob seed.

Is an H color and SI2 clarity a good choice for a center diamond in a ring ?

H colored diamonds will have a slight yellow tint but this will be hard to see when set in the ring, especially with no white light or background. SI2 diamonds offer a great value for money since they are relatively affordable and still offer a nice looking diamond with a good sparkle and brilliance to it.
