Diamond Carat Weight Guide

What is a Carat?

One carat is quite simply the metric measurement of 0.2 gram or 1/5 gram.
You take the diamond, put it on a scale like the one on the right, and it tells you the weight.
Sometimes, a system of points is used to describe the carat weight of a diamond. 1 carat is equivalent to 100 points. So, a 75 pointer is the same as a 0.75 carat diamond

To be exact the brackets on prices are separated like this:

0.30-0.39
0.40-0.49
0.50-0.69
0.70-0.89
0.90-0.99
1.00-1.49
1.50-1.99
2.00-2.99
3.00 -3.99
4.00-4.99
5.00-5.99

0.30-0.39 is rather small for a proposal ring. Only if she has mentioned she wants a really small diamond then you should consider this range.
Best buys for the price: F VS1,VS2 / E VS2

0.40-0.49 is a popular range for the minimum carat size as a proposal ring. Because you sacrifice on carat size, looking for a high color/clarity is something you should aim for! Impress her with the quality, not the size.
Best buys for the price: D VVS2, VS1,VS2/ E VVS1,VVS2,VS2 / F VVS1,VVS2,VS2

0.50-0.69 is to me, the favorite range for girls as a proposal ring. 0.58-0.69 will seldom come as super ideal cuts. Finding the perfect cut in those high ranges is rare and a little more common in the low 50's.
Best buys for the price: D VSS2, VS1/ E VVS1, VVS2, VS1/ F VVS1,VVS2,VS1

0.70-0.89 is where you're ready impress. G color is quite acceptable at this carat size because size is speaking!
Best buys for the price: D VS1,VS2/ E VVS1,VVS2,VS1,VS2/ F IF-VS2/ G VVS1-VS2

Tips: Try to avoid rounded whole numbers. e.g 0.40, 0.50, 0.70. Lets say you purchase a 0.50, and the diamond gets chipped/damaged, re polishing will cause the diamond to lose weight, and fall into the range of 0.40-0.49, causing a large drop in value.
