At the conclusion of the Diamond Mines, you will find a bunch of diamonds together. One of them is the white jewel. To find out which one, use the Magnifier loupe at the bottom right of the screen. The white jewel has a triangular inscription on it, and it should be one of the three stones at lower left. When you see it, click "take" to pick it up.
Use the magnifying glass (bottom right) to find out which jewel has the Nabooti seal on it. The jewel will be near the bottom left, so look for the triangular mark.
It is near the left on the end but first you have to blow open the rock and the cave and get past the mine carts.
i dont know but its not any other site will help.i tried 1,000,000 sites and they were all wrong SORRY:(
The white jewel can be distinguished from the other diamonds because it has a special symbol on it. Use the magnifier at the bottom right to examine all the diamonds. It should be the third one in from the bottom left side, and bears a triangle mark. (see related question)
Dodge the mine carts, go down the elevator, blast the rock and the wall, ride the mine cart, and get the White Jewel from the diamond pile. (see related question)
Find the bush that is on a rock in the right side of the falls. Go behind it to find the cave that has the Purple Jewel.
The White Jewel is the only one of the diamonds with a triangular mark on it. Use the magnifier (bottom right) to look at all of the jewels. It should be on the lower left side of the pile.
Once the woman and her animals have crossed, you can go to the right side of the falls and move the bush on a rock there to reveal a cave. Inside is the Purple Jewel.
Once you get the animals across the falls, you can go to the small bush, on a rock to the right side of the falls. Behind it is the cave with the Purple Jewel.
The White Jewel is in a bunch of diamonds at the end of the mine. Use the magnifier to look for the triangle mark that makes the White Jewel different from the other diamonds. To reach the White Jewel, turn off the power switch and quickly run to get through the electric fence. Dodge the mine carts and enter the mine. Use the explosives by the elevator to blast the rock and the wall. Ride the mine cart and don't forget to duck and jump.
The Purple Jewel is at Blue Nile falls, in a cave behind a plant on top of a rock on the right side. You can only go in the cave once you help the woman across the falls with the animals. The Red Jewel is in the old man's icy cave at the Mountains of the Moon. You have to climb the trail and beat him at the Mancala game. (see related questions)
get the exploding berrel drag it to the rock and turn off the switch
