EXCLUSIVELY FOR SEED2STONE FLAT BACKS
The Flat Back Posts are specifically for Seed2Stone flat back jewelry. These threaded posts let you customize your fit so your studs sit comfortably, securely, and exactly where they should.
Having multiple post length options matters as piercings heal, shift, and change over time. Swelling can fluctuate, pressure points move, and different areas of the ear often require a different length. The right post helps reduce irritation, relieve tenderness, and support smoother healing while allowing you to move your jewelry comfortably. All Seed2Stone Flat Back studs already include both 5mm and 6.5mm posts. This bundle expands your options so your jewelry continues to feel supportive, intentional, and easy to wear.
✦ Four post lengths for custom fit: 4mm, 5mm, 6.5mm, and 8mm
✦ Posts are 18-gauge surgical-grade titanium threaded posts with 18K gold PVD plating

Bought as a gift for a close friend for her birthday. She loved them and wore them to her birthday party! They looked great on her and she said they were super comfortable too!
I purchased the xsmall hoops and wore them for weeks straight, but also wanted something more substantial, these are the 12mm. Quite a size difference, they very much have a presence and I appreciate the look. Have worn them 24 hrs a day for the last two days,they are very comfortable to sleep in, so I can see leaving them in for a while like I did the xsmall pair. Once I get an upper lobe piercing my goal is to buy the small and sometimes wear all three sizes together! (I now have 4 pieces from seed2stone, I’m also eyeing the Rockstar when I’m able to change my helix piercing)
Beautiful earrings, my 1st purchase and I’m hooked, wanting them in every size. These are the xtra small, they are tiny and hug my fat earlobes, but I love the fit, very comfortable. Have worn them 24 hrs a day and they’re perfect to sleep in, never took them off for the first few weeks I had them. These are my 1st lab diamonds and I’m very impressed with the cut & sparkle, no different than excellent cut natural diamonds.
I’ve never had an open ring like this and I’m loving the look! Easily fits my pointer finger, although I have worn it on my middle finger as well. Diamonds really catch the light. Now I’m hooked on the open style and will probably get the pear shape next!It’s my second purchase from seed2stone, very happy!
The .53 necklace is my 4th purchase and I’m in love, it’s beautiful. The stone is a great size for every day and the paperclip chain is very timely. The diamond really sparkles and catches the light. The secondary diamond isn’t very noticeable but it’s cute when I do see it. I’m wearing the necklace using a little bit of the extension (jump hoop is at 17”), around 18.5” layered with another paperclip chain at 20” and it looks great. Keep checking it out in the mirror, it was a little bit of splurge, but I’m glad I went with the larger stone.
i love my new diamond stud for my extra lobe piercing on one ear. i got the 2mm one and it’s actually a little larger than i expected. i appreciate that it came with two size posts, however, i needed the longer option for my upper lobe and it wouldn’t be long enough for my lower lobe piercings. i would likely buy more if there were a longer post option.
I love these. They are so comfortable I can wear them continuously.
I'm in love with these hoops. I got the silver 12mm. I sleep in these and don't feel a thing, which is awesome I'm a lazy gal who doesn't like to take stuff on and off constantly, nor make a lot of decisions in the morning- but I still want to look good! Haven't taken them off since I got them. The size is perfect for me as I like to wear jewelery that makes a statement, but is still cool and tasteful. Like a lot of my peers, I only buy lab grown diamonds, so these are just perfect. Highly recommend.
Makes it so much easier to put in flat back earrings - great purchase.
I just bought this piece and the beauty bar necklace to layer and I am so incredibly happy with my new look! I feel unique in how I wear them because I chose this specific look. Thank you seed2stone for making it easy to sparkle better!
Beautiful! I am getting so many compliments! Very comfortable and well made. Good bling!
I love every single earring I have ever gotten from Seed2Stone , but this one exceeded my expectations if fits my helix piercing perfectly and looks amazing. You will receive 2 post lengths which is great because I really did not know which length I needed and a easy to use tool to change your earring. They just think of everything.
I have been wearing it 24/7 and it is very comfortable.
This is the first comfortable ear cuff I have had (and I've tried many!) It looks great, is completely suitable for everyday use, and feels super high quality. As an added bonus, it shipped super quickly and came in really beautiful packaging. I highly recommend!
It’s the perfect size, very comfortable and works with my other earrings.
Can we tell you a bit more?
Why choose a Flat Back Stud
Flat back studs are inserted from the BACK, then the front stone inserts into the opening and screws in place. They are a great option for those piercings that you do not change often and want to leave in all the time. The flat back means:
- that you don't get poked in the head or get caught on towels etc
- backings won't fall off
- they are safe for all kinds of SPORTS
- and best of all, you can sleep comfortably in them
You might need help inserting them, but once they are in, you are good to go!! If you have difficulty with putting them in, all piercing shops will do this for you for a minimal charge.
Lab-grown diamonds are very REAL.
Lab-diamonds are chemically, physically and optically the same as mined diamonds. After they are grown from a seed in a lab, they go through the exact same cutting, polishing and grading processes as mined diamonds. You can only tell the difference between them by sending them to a lab for screening.
Our metals are hypoallergenic and safe for all your holes!
The posts are surgical grade TITANIUM, plain or with gold over for yellow gold styles. The stones are set in 14K white and gold which is also NICKEL FREE.
Size matters. How to pick the right one.
We know that comfort and fit will make the difference between an OK and everyday-never-take-off! All styles come with BOTH a 5mm and a 6.5mm post so that you have options.
We stand behind our craftsmanship.
If you need any repairs, including lost stones, we will repair it for you. If it is due to manufacturing defects, this will be at no cost, otherwise, we will give you a fair quote for your approval.
