It would help if you specify whether you are talking about thermal conductivity, or electrical conductivity. Diamond certainly doesn't has the highest electrical conductivity. Its thermal conductivity is one of the highest known, and - if a synthetic diamond is made from pure (99.9%) C-12, it is indeed the highest. The Wikipedia article attributes this to a strong covalent bonding.

How does being a metalloid metal or nonmetal affect conductivity?
Metals are generally good conductors of electricity.
Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.
What mineral has the highest number on the mohs scale?
Diamond, with a hardness of 10 on the Mohs scale.
Which has the highest conductivity between sodium chloride crystal and 5 percent sodium chloride solution?
The solution being an electrolyte is electrically conductive.
Is germanium a metal nonmetal or metalloid?
AnswerSemi-metal And a metalloid.
Does carbon have some properties of metal and nonmetal?
Yes, carbon exhibits properties of both metals and nonmetals. In its graphite form, it exhibits metallic conductivity and can conduct electricity, akin to metals. However, in its diamond form, it displays nonmetallic properties, such as being a poor conductor of electricity and having high hardness. This duality allows carbon to be categorized as a metalloid in some contexts, depending on its allotrope.
Is nitrogen a metal a nonmetal or a metalloid?
Nitrogen is a nonmetal. It is found in group 15 of the periodic table and typically exhibits nonmetallic properties such as being a poor conductor of heat and electricity.
What property of nonmetal is the opposite of being malleable and ductile?
Harb
What is a white diamond with a number in?
'White' diamonds are graded in colour using letters of the alphabet, from D to Z, D being the highest grade. A number in a diamond's description can reference its weight in carats, or the number of visible flaws.
Is sulpur a nonmetal?
Yes, sulfur is a nonmetal. It is positioned in the nonmetal group on the periodic table due to its properties such as being a poor conductor of heat and electricity, and not having metallic luster.
Why is neon a non metal?
Neon is classified as a nonmetal because it lacks the typical metallic properties such as malleability, ductility, and conductivity of heat and electricity. Nonmetals generally have properties opposite to those of metals, with neon displaying characteristics such as being a gas at room temperature, low melting and boiling points, and poor thermal and electrical conductivity.
What is the highest grade a diamond can be?
Diamonds are graded according to cut, colour, clarity and carat weight. When cutting a rough diamond stone, the diamond cutter first determines the natural colour of the stone, then plans a cut that preserves the highest carat weight for its maximum clarity. So the highest grade of diamond is the largest stone with zero flaws in the rarest colour with the most perfect cut for that stone. These diamonds are sold at auction and bring millions of dollars to sellers. In jewelry, the D colour is the highest grade colour; internally flawless is the highest clarity, blue and red could be the rarest natural colours. The Gemological Institute of America's Web site will help you better understand the four Cs, below. Finally, exceptional stones, are also graded according to the type of diamond, the most common being Type I. Read more about diamond types, below.
