Here's a little guide to solving a puzzle ring.
Begin by arranging rings as illustrated in figure 1:
Ring @ left is Ring A (two indents)
Ring @ right is Ring B (four indents)
Ring @ bottom is Ring C (one indent)
Ring @ top is Ring D (three indents)
Figure 1
Holding in left hand, arrange so that rings A & B from a diamond shape, A is on the left and B is on the right, C is closest to you.
Figure 2
Rotate D clockwise until it locks over bottoms of Rings A & B. Rotate Ring C couter clockwise u ntil it locks with Ring D forming an X as illustrated. Use left pinky finger to hold Rings C & D in place.
Figure 3
Rotate Ring B as shown.
Figure 4
Continue rotating Ring B until it is in this position
Figure 5
Flip the bottom of the shank down and B will lock in place with Rings C & D as shown.
Figure 6
Rotate Ring A away from body as shown in illustration 6.
Figure 7
When Ring A is positioned as shown in illustration 7, flip bottom of shank downward and lock in position as shown in illustration 8.
Figure 8
Ring is complete.
Here is a selection of charts showing the Carat Weights of Diamond corresponding to their sizes. These are indicative only, as every diamond is cut slightly different and so will vary from these guide sizes.
Also, other gemstones, having different specific gravities, will weight more or less than diamond for the same sizes, so these charts will not be appropriate for those.
Measuring a finger size for a ring can be surprisingly complex. Below we highlight some of the common issues that arise and provide a chart of some of the more common international sizing systems.
Many countries and regions use their own ring size chart. Here is a list of some of them. These are approximate comparisons as many of the sizes from one region have no exact corresponding size from another - however, the differences will be very minor.
