Q&A: Looking for a .30 Ct. Round Diamond for a Solitaire With a $2k Total Budget

By Mike Fried,

Glad to find your great website.

I’m looking for a dupe of the Tiffany setting with platinum band and around 0.30ct, I have a budget of $2,000.
Could you help me please?

Thank you in advance!

I looked around and I love this combination for you:
Blue Nile Six-Prong Low Dome Comfort Fit Solitaire Ring
(We don’t think you should waste money on platinum: https://www.diamonds.pro/education/platinum-vs-gold/.)

Blue Nile LD07243706

J color is our usual recommendation for that type of setting. This diamond is fantastically cut and will be very brilliant.

What do you think?

Thank you for your reply.

I’d prefer this style of setting:
Blue Nile Nouveau Knife Edge Six Prong Solitaire Engagement Ring

I wanted to have platinum because I’m afraid that white gold will lose its color after a while and will need to be “re-colored” otherwise it will become half-gold half-white when platinum will only need to be polished. Do you think platinum is a better choice in long term?

As for the diamond I would like to have one around 0.3 ct with these features:
– Color: At least F
– Clarity: At least VS1
– Cut: At least Excellent
– Excellent Polish and Symmetry: do you think it is really important? I’d love a diamond as perfect as I can have with my budget.

Thank you so much for our help!

You’re welcome.

For metal, we always recommend white gold over platinum because of the huge disparity in upfront costs: https://www.diamonds.pro/education/platinum-vs-gold/.

Both metals require upkeep every few years. WG needs to be dipped to retain its color and luster while PT needs to be cleaned and polished because it gets scratched and duller over time. So in the end, platinum costs you more in the beginning and doesn’t end up saving you any money in the long run. And I’d recommend 14k white gold. It’s cheaper and more durable than 18k.

This would be my new recommendation then:
Blue Nile LD07122957
Blue Nile LD07510281

These diamonds are superbly cut, clean and the overall specs are perfect on them. Either of them will be incredibly brilliant.

What do you think?

I just read that the 6-prong knife edge solitaire that I’d like to have is sized only from 5 to 9 while I’m a 3.5, and it can be only set with a diamond from 0.64 ct.

I prefer thinner band so I found another one similar:
Blue Nile Classic Six-Prong Engagement Ring

What do you think?

Between the 2 diamonds that you sent me, I think the 0.50 is too big because I want to couple the solitaire ring with a wedding ring in this style but very thin (I think it is 1.4 mm).
Blue Nile Petite Pavé Diamond Ring

With the 0.30ct. I’d love to have a diamond a little bit more perfect, like the one that you sent me but with excellent polish for example. (Do you think that it is necessary?) And consequently a tad more expensive, maybe around $700.

Thank you so much.

……

What do you think of this one?
Blue Nile LD07877101

Thanks a lot!

I’m glad you worked it out with the setting. The new one looks great too.

The diamonds I sent you are superb. They will be extremely brilliant and very clean. The polish grade is completely fine: https://www.diamonds.pro/education/polish/.

Is there a reason you want to get a more expensive stone? I can search for one, but then you’d still get the same look for the naked eye with a significant price difference.

Thanks so much for your prompt reply and enthusiasm.

I just think that the higher grade a diamond has in terms of color, clarity, polish and symmetry, the brighter it will look in real life.

You think we should not pay a higher price for the slight difference?

And I notice the girdle? Which one should we choose: thin to medium, medium or medium to slightly thick?

Thank you.

……

Would you recommend Blue Nile over James Allen?

I see a lot of references from JA on your website.

I quite like their 6 prong setting but its much more expensive than Blue Nile’s one (double the price). Do you know why?

What about Brian Gavin? I’ve heard that he make sophisticated setting, like this one: www.briangavindiamonds.com/engagement-rings/solitaire/six-prong-solitaire-14k-white-gold-5351w14?a_aid=y

But their diamonds seem expensive, this is the cheapest one I found in my category:
www.briangavindiamonds.com/diamonds/diamond-details/0.302-g-vs1-round-diamond-ags-c-104084105069?a_aid=y

I think Blue Nile is the most reasonably priced but which one has highest quality in terms of setting’s design and diamond?

Thanks a lot!

You’re welcome.

I see which direction you’re headed, but I’d still recommend adjusting your parameters a bit. It is cut what is the most important aspect of the diamond, that is what makes the diamond beautiful and brilliant. A very well cut G will look much more beautiful than a poorly cut dull looking DEF.

Girdle is fine. As long as you avoid extremely thick/thin one it’s ok.

Both James Allen and Blue Nile are reputable companies and we recommend them to our readers often. Choosing one or the other always depends on each reader’s specific requirements. You can find a great value on either site.

As for the prices, Blue Nile prices are just a little lower in general. Both of the companies have settings of a great quality.

Brian Gavin is an excellent choice. He is known as one of the worlds experts when it comes to perfectly cut diamonds. BGD’s Signature diamonds are truly fantastic. They are all incredibly brilliant.

The diamond you found there is amazing. However, it comes with the premium to be paid. Personally, I like the Blue Nile diamonds more, their cut is equally fantastic and their price is more reasonable. But it’s up to you.

Thank you for your fantastic answer and help, I know where to head now, I’ll adjust my search and let you know when I find one.

I’ll also mention you and your site when I purchase from one of them if you don’t mind.

Thanks a lot and hope you have a nice day!

You’re very welcome, I’m happy to help.

Let me know what you decide on in the end.

I’m really hesitating between Blue Nile and Brian Gavin. The pictures online show that BN’s prongs are a little bit bulky and the BGD’s ones are smaller and more sophisticated.

Since my diamond will not be very big, I’m afraid that bulky prongs would almost cover it.

As you can see in this photo, the left one is Blue Nile and the right one is BGD.

Do you think that this is worth the price difference?

I found this diamond among the “cheaper” ones:
www.briangavindiamonds.com/diamonds/diamond-details/0.270-i-vs2-round-diamond-bfg-22296?a_aid=y

What do you think?

Thank you so much and have a nice day!

The new diamond is beautiful too.

Well, the choice of the setting is entirely up to you and your taste. If you want, you can ask BN if they would be willing to adjust the prongs for you.

Finally I think I like the head of this JA knife edge setting most, but it is quite expensive, $910 for 14K white gold and what surprises me is that in 18K and PT it is not much more expensive, unlike other rings!
www.jamesallen.com/engagement-rings/solitaire/14k-white-gold-six-prong-knife-edged-solitaire-engagement-ring-item-22590?a_aid=dmnd1357

If you notice the head, it is very different from BGD and BN’s ones, much more “softer”, thus the difference in price maybe.

Blue Nile Classic Six-Prong Engagement Ring

Do you know any other brand who makes this kind of setting with head similar to JA or the classic Tiffany’s one?

Thank you!

I see. Personally, I’d be deciding between BGD and JA, I like their settings more than the BN’s.

I found this one:
www.since1910.com/ur8107-six-prong-solitaire-setting

What do you think?

I’ve been looking at settings of Since1910 and quite like them, are they reliable? I don’t know much about them since they seem to be less popular than Blue Nile, James Allen, Brian Gavin, etc.

Thank you very much.
