Solitaire Ring

What Makes a Ring a Solitaire?

The word is French for alone, and it describes stone count, not setting. A ring is a solitaire when one stone is the whole design. The stone is most often a diamond, though sapphire, emerald, and moissanite solitaires are common.

Most solitaires use a prong setting, with four or six prongs lifting the stone clear of the band so light enters from the sides. A bezel solitaire wraps the stone in a metal rim instead. Both are still solitaires, because the style is defined by the single stone and not by what holds it.

A plain band is the classic version. Many jewelers also sell an accented solitaire, with small stones along the shoulders. Strict usage reserves the name for rings with no side stones, so a shoulder-set ring is usually listed as a solitaire with accents.

Solitaire vs Halo

A solitaire puts the whole decision on one stone. A halo ring surrounds the center stone with a ring of small stones, which is covered under the halo setting. The two answer different briefs: the solitaire shows the stone as it is, and the halo frames it and adds sparkle around it.

The practical differences come down to a few points:

• Stone count: a solitaire has one; a halo adds dozens of small stones
• Look: a solitaire is quiet and open; a halo reads larger and busier
• Cleaning: a solitaire has fewer places for dirt to collect
• Resizing and repair: fewer small stones means fewer things to disturb
• Honesty of the stone: a solitaire shows every flaw in cut and color; a halo hides some

What a Solitaire Means for a Render

A solitaire is one of the quickest rings to render, because there is very little geometry to build. A heavily pave-set piece typically adds 20 to 40 percent to a render. A solitaire adds nothing, since there are no small stones to set one by one.

The catch is that the single stone gets all the attention. Its facets, proportions, and the way it throws light have to be right, because nothing else on the ring distracts from them. A badly proportioned stone in the CAD model will look badly proportioned in every image.

Send the file in 3DM, STL, OBJ, or STEP. From one file you get 9 HD images and 3 videos, in rose, white, and yellow gold, and the same solitaire can be shown in all three metals without remodeling the band.

Where a Solitaire Render is Harder Than it Looks

A simple ring has nowhere to hide a weak render. Budget renders show their tells most clearly on a solitaire: metal that looks plasticky, and a stone that glows instead of sparkling. On a halo, the small stones draw the eye away from those faults. On a solitaire, the eye goes straight to them.

Prongs are the other pressure point. Their tips, the way they grip the girdle, and the small gap under the stone all have to read correctly at zoom. A clean CAD file renders at the base price, but a solitaire with sloppy prong geometry needs repair time first.
