danisweng: As small as your hands are, you can go as small as they come 3 mm .12 (1/8) ct center stone. The Halo stones could make a bigger difference as they may very from 0.8 mm to 2 mm typically. 3 mm would look like part of a cluster next to 2 mm halo stones. 0.8 to 1 mm halo stones around 3 mm would look ok.

 

Ideally I would think a 4 mm .25 (1/4) ct to 6 mm .80 (4/5) ct would look best as the center of a double halo. A .30 to .36 ct center would be about 4.5 mm, with in this range.

danisweng:  Something else to keep in mind is the propotion of the halo size to the center stone. Check out this optical illusion: 

Can you believe both orange cirlces are the same size? For this reason, I prefer a more dainty halo to make the center stone the showcase 🙂 My ring has 1/2 pointers in the halos.

Your rings are beautiful!!! I just switched my setting to this double halo from a single halo. 1ct center stone…2ct TW…I’m on the fence about it…I still have my original setting. #confused

My center stone is 1 carat, surrounding diamonds are .30 carats and sapphires are .20 carat. Ring size is a 5. Good luck!!!

My Fiance surprised me with the Tiffany soleste :). Mine is 0.56 ccw and it looks PERFECT on my size 5 finger. Hope it helps

danisweng :  That is a really nice inspiration. But, I’d suggest you approach this from a different angle. What percentage of your finger do you want covered by a ring? If you look at k_girl3, FutureDrAtkins and PenguinCanday…they all about about 75% finger coverage. So, on a size 4 finger, you would need a 4.5 carat Round to get that coverage, which is about 10.5 mm. So, the entire ring should be about 10.5 mm. You could change this to 80-85% without the ring hitting your other fingers. 

The halo you posted is a lot of halo relative to center stone. I’m not a fan of those proportions. The most beautiful halos I’ve seen have between 30 and 55% of the stone width made up by each side of the halo. Your inspiration has 100% of the stone width on each side of the halo. I’d really think about this. 

Ok…doing the math for you…

2 rows, 1/2 point (1mm) diamonds = 2.0 mm * 2 sides=6.5/2 ~ 4.0 mm

10.5 mm (target width)-4.0=6.5 mm = 1 carat diamond  (31%)

 

1 row 1/2 point (1mm) + 1 row 1 point (1.3 mm) = 2.3 mm * 2 ~ 4.6 mm

10.5 mm (target width) – 4.6 mm = 5.9 mm = 0.7 carat diamond (39%)

 

A few more halo pointers that arise on this board & every other board when people are not happy with their halo. 

***The single most important thing to determine a diamond’s performance is cut. Cut is king, as they say on PS. The cut should be ‘excellent’ on the GIA report. Don’t hesitate to look at H,I,J color stones. You may be surprised. For clarity, look at VS1, SI1, SI2. You want a gemologist to tell you it is ‘eye clean’ at 8-10 inches. Period. If it is eye-clean, that is all you want. 

  • Stick with a center stone that is GIA, HRD Labs, AGS or GCAL. NOT EGL, IGI, GSI, PGS, not a ‘branded’ stone, not joe-schmoe or the store manager’s recommendation. GIA is the toughest grader, if the diamond seller did not send the stone to them, they knew it would grade lower than they wanted to label it.  
  • Use very well-cut melee, that means you spend more, but insist on this. Cut must be excellent. Color should be within 2 of your center. 
  • Each halo should be tipped downward from level by 20%. See below pictures. 
  • Pave halos are fragile as compared to other settings. You must be prepared to take this off during exercise, gardening, sleep, etc. They are also not well-executed by many. Make sure to examine a similar setting by your chosen maker carefully. Bead or grain setting can be more secure. 
  • The girdle of your center diamond should be resting on the opening in the halo. See below images. 
  • The prongs holding the little diamonds should be dainty and very well formed. 
  • For a round in round halo, use 6 prongs or 8 prongs (dainty claw prongs!). This will help emphasize the shape of the round stone. 4prong tend to make the stone look square. 
  • You need to decide on the kind of wedding band you want to wear as this is key to deciding the height of the halo off your hand an design of the gallery. If you hate curved bands, that the entire gallery needs to be designed for a ring to slip beneath it. 
  • Pave band only down to 1/2 way point. That band should be no thinner than 2.0 mm if you want this to last.’
  • Platinum (90PT/10IR or 95PT/5 RE) are the best choice for pave, but gold (14 or 18k) is fine. Just know that you may be inclined to loose more stones in gold that platinum.

Properly Set Stones – see how it tucks into the halo? See the tilt of each halo? This is exactly what you want to see.

The Leon Mege double uses larger halo stones — but the prongs are far less apparent. This also helps the look seem seamless.

Well, my comment disappeared.

I love the idea of a double halo, but the halo you posted is not my favorite. Your inspiration halo has 100% the width of the center in each side of the halo. The most beautiful halos I’ve seen have 10-55% of the stone width on each side. Search for halos by Leon Mege, Steven Kirsch and Victor Canara. 

My advise is you approach this from a different angle. What % of your finger do you want covered? Most of the halos here are about 75% coverage. On a size 4 finger, that would be 10.5 mm. Assuming you take the excellent advise about halo stone size in that optical illusion, here is how the math works.

 

{1/2 point melee (1 mm) * 2 rows} * 2 sides of the ring = 4.0 mm

10.5 mm – 4.0 mm = 6.5 mm = 1 ct diamond (31%)

 

{1/2 point melee (1.0 mm)  + 1 point melee (1.3 mm)} * 2 sides of the ring = 4.6 mm

10.5 – 4.6 mm = 5.9 mm = .75 c diamond (44%)

Halo pointers, In My Humble Opinion

~airline or not. Personal choice. Just make sure you are clear about which you want and make sure that your chosen stone and setting will yield that outcome.

~excellent cut melee

~each row of melee tilts 20-25% from level. The setting is not flat. The two rows of meless should look like steps. This provides a gorgeous view from the side and does lovely optical things with the diamonds. The melee will look sparklier from the top. 

~ask for ‘cut down’ or ‘u-cut’ pave for the most beautiful pave.

~stone is set into the halo. The girdle should be barely visible from the side (with magnification only), but the rest of the stone should be inside the setting.

~round in round will look better with 6-8 dainty claw prongs

~pave is one of the more fragile settings types. Treat it with care, don’t sleep, exercise or garden in it. 

~pave is one of the hardest setting to do well. Examine the jeweller work under a loupe. 

~if you pave the band, the band can be no narrower than 2.0 mm if you want this ring to last

~platinum is best (90PT/10Ir or 95PT/5 Re), but gold will be fine. Just be prepared to lose more stones in gold.

~Halo settings can be low or high. You need to decided. Have then show you with a solitaire, if necessary, exactly how high the setting will be with your stone in it.  Make sure you like this. To lower the head (halo part), they can do that, but it will likely mean that you can’t get a flush w-band. 

Tiffany Soleste – Note the propotions are not as shown in your inspiration. This is taken from a Tiffany ad. The each side of the halo is about 45% of the stone width.

45%

50%

CORRECT STONE HEIGHT IN HALO WITH STONE LOW IN THE SETTING. GIRDLE FLOATS ABOVE THE OPENING, SHOWS THE 20% TILT OF EACH ROW OF STONES. THE HALO SHOULD NOT BE FLAT! If you buy a stock setting, make sure you don’t buy one that will have a huge or small opening relative to your stone. Make sure they say that you can set the stone like this in that particular setting.
