Yes, if you are comparing a specific diamond to a specific amount of platinum and whether or not it is a setting for a stone or just a lump of metal. The value of a diamond depends on the quality of the individual stone which is based on clarity, cut and color. Platinum is the most valuable metal on earth, but it is weighed differently than diamonds. There is also value of the workmanship when talking about platinum such as in the design of the mounting for a ring or other piece of jewelry. On the whole comparing the value of diamonds and platinum is much like comparing apples to Oranges.
Palladium and platinum are rarer than gold and they have more uses in science and industry.
You cannot really compare the two as one in a gemstone and the other is metal. Both have qualities that add value to the price.
This is a partial quote from the Wikipedia, "Palladium, along with platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Platinum group metals share similar chemical properties, but palladium has the lowest melting point and is the least dense of these precious metals." Please see the related link for more information on palladium. You may want to contact a jeweler for a price per ounce comparision with platinum. You can avoid manually calculating the value of palladium if you have an iPhone or iPod by using an app called Pennyweight. Simply entering the weight and selecting the purity will automatically calculate the value of palladium based on the current market price.
Gold
No. Platinum is worth far more.
Platinum is more expensive than titanium currently.
Platinum is more rare and expensive than gold. As to better, it may depend on what you want to use it for. Platinum is used for jewelry, and an investment broker once told me that platinum jewelry is very popular in Japan, while gold jewelry is preferred elsewhere in the world. There may be some industrial uses for platinum which make it better than gold, perhaps in the field of electronics.
Gold, platinum metals (platinum, palladium, osmium, rhodium, ruthenium, iridium), rhenium, etc.
Palladium is more durable and harder than gold. Palladium is usually an attractive alternative for platinum and white gold. Palladium is also hypo allergenic so when you wear this type of metal, you will never experience any discomforts or allergies.
Platinum tends to be worth more than gold by weight, but as prices fluctuate, sometimes the gold price does go higher than the platinum price. Silver, at least in recent history (probably all of history) is worth significantly less than both gold and platinum.
Gold is more expensive at the time of writing. Palladium is about $820 an ounce while gold is about $1,340 an ounce.

These are some metals that are more rare than gold: Ruthenium, Palladium, Platinum*, Rhenium, Iridium, Rhodium, Osmium *Platinum is actually more abundant than gold, but because there are far less minable sources, it is considered to be rarer than gold. These are more expensive than gold: Platinum, Rhodium I would consider human life/soul more precious than monitary value. Some may also consider memories or experiences high valued. Pretty much anything you can't put a price on.
Gold is not very reactive, but platinum is more nonreactive; the electronegativity of gold is 1,93 but the electronegativity of platinum is 2,23.
