What Stone Sizes Mean and Which Tray Fits

Rhinestone Size Guide SS12 SS16 SS30 | Seery-Us Visionz

If you've ever ordered stones and been surprised when they arrived, this one's for you.

What SS actually means

SS stands for stone size. The number goes up as the stone gets bigger.

Rough guide:

  • SS6–SS10 — Fine detail, nail art, small accents.
  • SS12 — the most common size for detailed bling work. Small enough for detail, big enough to handle.
  • SS16 — a step up. Good middle ground. My fav for honeycomb
  • SS20 — noticeably chunkier. Fewer stones to cover the same area.
  • SS30 — big. Statement stones, bold coverage, fast fills.

Why this decides your tray

Bigger stones need bigger wells. Not because they won't fit in a small one, but because they won't move in a small one and moving is the whole point of a flip tray. Stones need room to shift so they turn face-up when you flip.

Cram SS30 into a small well and you get a jam instead of a flip.

The general rule:

  • SS12 and under → small inserts & smaller projects
  • SS16–SS20 → medium inserts & medium projects
  • SS20–SS30 → large inserts & large projects

Which trays are sized for what

Synclaire runs a full line layout for SS30 big stones, clean rows.

Scooter comes in three styles: Split Grid/Line for SS12 if you place individual stones and run rows, Full Line SS12, or Full Line SS30.

Kev's Bling Box splits either into quarters at SS16 or halves at SS30 same footprint, different division.

The interchangeable family Betty, Rose, Truby, Blanche XL, The Rue adapts to whatever you put in it, which is why those are the flexible choice if you work across sizes.

If you're only buying one

Go with medium or large inserts. It's the most-used size, it's forgiving, and it's what most patterns assume.

Then add specific inserts when you find your own preferences. Since the inserts move between trays, that's an add, not a do-over.
