Q&A: Finding a 1 Ctw. Best Cut Round Diamond Earrings For a Platinum Setting

After several decades, I finally discovered that platinum was the only thing I was NOT allergic to. So, I purchased a nice pair of diamond studs set in platinum. That was 15 years ago, and I recently lost one. So I am now researching and educating myself on diamonds before purchasing another pair. I have found your reviews very helpful.
I am looking for maximum brilliance and sparkle.

Can you please tell me the difference between:
1)James Allen True Hearts
2) Brian Gavin Signature Hearts & Arrows
3) Blue Nile Signature

Or are all 3 considered “equal”?

I have been looking at diamonds, and settings, and also tried on some earrings at a local retail jeweler to get an idea of what size I want. I tried on 3/4 ctw, and thought they were a little too small. I tried on 1 ctw, and thought that they were about as big as I wanted to go. So, I guess that would give me a range of around 0.85 or 0.9 to just over 1 ctw to search.

I found this setting that I really like on James Allen:

And this very similar setting on Brian Gavin:

The setting has to be platinum due to allergies to other metals. I didn’t know if it would be a big hassle or expense to purchase the setting from one and the diamonds from the other?

I pretty much have my heart set on Brian Gavin Signature, from all the great things I have read about them, but am not completely closed to other suggestions. I would consider the Brian Gavin Blue but I would like to know a little more about them. When exactly would they appear blue? In natural sunlight? Fluorescent lighting? I placed a few matched pairs in my “wish list” on the Brian Gavin site, and was amazed that they were gone so fast.

I do not need to buy them today or even next week. Finding “my” perfect diamonds is more important that finding them fast. My price range is $3000-$4200. I could possible go a little higher for something really extraordinary.

I don’t know about color/clarity – I will leave that to you. I want “knock your socks off” sparkle and brilliance, to the naked eye. No one is going to be looking at these through a loop.

Thank you for your help.

I am looking at a couple sets of Brian Gavin diamonds, and would like to know what you think of them.

I had both sets in my wishlist. The second set is gone – not even showing in my wishlist anymore.
……

I have another pair of diamonds that I would like you to look at and compare to the first set. I will be ready to purchase soon based on your recommendations.

First set
AGS-104091555028 0.506 I VS2 $3186
AGS-104091555026 0.503 H SI1

Second set
AGS-104091064038 0.513 I SI1 $3039
AGS-104091555026 0.503 H SI1

……

Sorry for so many fragmented emails. Could these two be put together as a matched pair?

AGS-104091064038 0.513 I SI1 $2957
AGS-104091555028 0.506 I VS2

I made my decision and sent payment to Brian Gavin this morning. I chose the 0.513 I SI1 and the 0.503 H SI1 that you recommended. That was the easy part. The hard part for me was choosing the setting. I finally decided on the truth stud setting in platinum with la pousette backs:

I can’t wait to see them! Thank you for your help! Jamie at BG was very helpful, as well.
