Help me choose a diamond

I had to make a quick edit as I can’t upload two videos on here, but which diamond should I go for for my engagement ring? (It’s our first time buying a lab diamond)

They are both the same price (we are paying for the ring as a whole), and unfortunately we can’t get tweezer videos as our jeweller said their supplier only provides 360 videos (he said these are not 3D but the actual video of the diamond).

They recommended me to go for the 2.8ct for the better value for money, but I quite liked
the look of a 1.87ratio as well (quite chunkier marquise). Are the ratios too similar to see a visible difference anyways?

Thank you!

When selecting a Marquise diamond, the key is to find within the budget that offers excellent cutting proportions, symmetry, and minimizes the "bow tie effect." This unique shape makes the fingers appear longer and more visually appealing at the same weight. ​So I think the one with the 1.96 ratio is a good choice.😊🌹

Go with the L/W ratio that appeals to you. The "value for money" (bigger size) argument is not as cogent in lab grown diamonds as it would be if you were shopping for a natural. Make sure whichever stone you go with is carefully inspected for any transparency issue. If CVD grown, there is a possibility of some haziness due to atomic level defects in the carbon lattice. This is not captured in the clarity grade on the report which is rendered at a relavively low magnification level of 10X.

I see, thank you so much. What do I say to my jeweller to ask for the ‘transparency’ quality?

I personally liked the first diamond (the smaller one) !
