Hi PSers,

I'm looking for a 1.5-1.8ct round MMD with super ideal cut quality. I found that Clean Origin has "H&A" filtering in their search tool, which is really nice. I didn't see this functionality on James Allen or Brilliant Earth. (BTW, What are other online MMD sellers which have a large selection of premium quality MMDs? I guess it's a niche market. )

After filtering on G+ color / VS2+ / H&A, and checking the table/depth/angles stats, I decided to go with this one: https://www.cleanorigin.com/round-lab-created-diamond-1a72ed3c03cd/. I placed order too quickly, now I felt a bit upset. Looking for assurance/input from PSers.

360 video and certificate: https://v360.in/movie/344_LG11263614

HCA score: 1.3

I'm mostly concerned about stria. I just learned about it, but not sure how to identify. Do these look like stria to you?

Could you share your opinions on this diamond? Thanks a lot :)

I can see Stria in the video. I’m not sure if/how it effects the diamond though. I actually was in a similar situation to you last week. I purchased a MMD from 1215diamonds and then I learnt about stria. The diamond I purchased looked pretty similar to yours in regards to stria. I ended up swapping it to a different diamond which didn’t have any stria showing in the video. I’m not sure if the stria would have been visible to the eye but at least the new diamond I replaced it with is mind clean. It’s due to be delivered in a week so fingers crossed!

Not an expert... but I think it looks decent in terms of cut, and the HCA score confirms the angles work well together :)

Stria can look like polish lines on the facets but I'm not sure if there's been any analysis yet of how they might affect light performance.

You've got the order coming and can view it in a range of lighting environments with your own eyes - that will be the best test to see if you are happy with it :)

Thanks for the replies! I found that some natural diamonds can also have stria-like patterns, like this one:

So I'm not sure whether this is due to polishing issue, or bad lighting.

Anyway the order is coming, so I'll check it with my own eyes and share the update here.

@Eeveepenny hope you to get a fantastic one :)

Oh I see, thank you!

Here is another vintage stone with the same "pattern" (but not as strong), is that polishing marks too?

Hard to tell on that one!

re: the previous one - the lines in the blue facet are obvious, but if one looks at the other facets round the pavilion, the same lines exist perpendicular to each facet, which would strongly indicate polishing lines (I think...).

Stria tend to be in the same direction across the stone, from what I've seen.
