Try doing some online search like on bluenile or similar websites to get an idea what you could get for your budget. If you are concerned about sparkle, i think it’s important to get a very well cut diamond with decent clarity. For a 0.3ct you could probably sacrifice color and clarity but make sure to get a triple excellent diamond on a GIA grading.

When we bought a diamond we went through the same thing. I was most concerned about the cut, because that’s what’s going to make it sparkle like crazy. A triple X diamond (excellent cut, symmetry & polish) is going to give you the best sparkle. I was willing to sacrifice color and some clarity (mine is still eye clean though) for that so I ended up with a 1.72 carat, H color, Si1, triple X. I couldn’t be happier. Don’t bother buying a flawless diamond because you can find one with a lower clarity that still looks completely perfect to the naked eye. Here’s a pic to show that even an H color is still pretty white. And make sure it’s GIA certified!

Short answer, post your wants and budget over on Pricescope-Rocky Talk, the diamond nerds will happily help you.

Very Long Answer:

You will get a much better deal with far less risk buying online since you can select for all the variables. Reputable dealers are JamesAllen, BlueNiles, Whiteflash, HighPerformanceDiamonds, Brian Gavin, B2C. WF and HPD have the best return and upgrade policies of these.

Look for GIAXXX or AGS0 (GIA is tougher on color, AGS on cut)

table – 54-58% (55-57, more fire)

depth 60-62.3% (59, sometimes)

crown 34-35 degrees (34.5, ideal)

pavilion 40.6 – 41 degrees 

Run all potential stone through the HCA Tool (https://www.pricescope.com/tools/hca). You want to see Excellent on light return, fire, and scintillation, and Very Good or Excellent on spread. An overall score of 2.0 or lower means a diamond is worth exploring further (but a 1.0 isn’t necessarily better than 1.9).

Anything not eliminated by the HCA is worth exploring. You want to look at an Ideal-scope or ASET to see light return.

Color: This is personal, but most people will ‘see’ tint starting at an I. But, an I or J with strong Florescence (that a gemologist says is not making the stone milky) can ‘lift’ the color of a J.

Clarity: VS1 & 2 are generally safe. Many SI1 that are very carefully selected can be great.

Cut: If you have to choose between GIAXXX and AGS0, go with AGS0.

Hearts & Arrows (or not): This is simply a cutting pattern (like comparing a jewish star to a 5-pointed star). Being H&A means the stone is cut to have precise angles that yield that pattern. The other way rounds are cut or usually ‘commonBut, this does not mean the stone will have good performance (sparkle, scintillation, brilliance, etc). For that, you need to look at the numbers above. Also, there is not an industry standard definition of H&A — but the super ideal diamonds will meet everyone’s standards.

No idea about your budget, but something like will have great performance.


Good performance, but the black inclusion on the center of the diamond would eliminate this for me.


But, if this is in budget, these are stunning.
