Your question is a valid query that is best answered by the process of supply and demand, which includes a distribution channel for each and marketing efforts for gem-quality stones.
These days, both high-pressure high-temperature (HPHT) and chemical vapor deposition (CVD) crystal formation technologies only produce about 2% of all gem-quality diamonds. Because the ancillary properties of diamond material -- i.e., conductivity, insulation -- can be controlled in the synthetic production process, the industrial application of diamond material may drive improved technologies.
Naturally occurring diamond material represents about 80% of all diamond material mined.
Why, yes, they are.
Pink diamonds can occur naturally and are rare and valuable. Their pink color is a result of unique conditions during their formation deep within the Earth's crust. However, pink diamonds can also be treated or enhanced through various processes, such as irradiation or high-pressure, high-temperature treatments.
Carat for carat, no gem is more expensive than a diamond, given a superior cut, clarity and colour classification. Other gems can be more expensive than diamonds when the diamonds lack top qualities.
Generally speaking, manufactured diamonds have the same chemical and physical properties of diamonds which are dug from the earth. So, yes, they are real. A certified gemologist will be able to discern a manufactured diamond, and will document it as such. Its value is considerably less than a natural diamond of similar characteristics. Manufactured diamonds are not natural diamonds. There are other man-made gemsones which are presented as diamond substitutes. Those are not real diamonds either.
Probably not genuine leather, or very thin leather
Why, yes, they are.
Genuine (natural) diamonds are formed deep within the earth's mantle, erupted to the surface through volcanic pipes and mined or gathered. Genuine (man-made) diamonds are formed in laboratories that attempt to mimic the conditions deep within the earth -- extreme high pressure and ultra high temperature -- and are manufactured over time. About 80% of all diamonds mined are industrial diamonds. Raw gem-quality diamonds are cut and polished into jewels. All diamonds are formed from carbon.
Pink diamonds can occur naturally and are rare and valuable. Their pink color is a result of unique conditions during their formation deep within the Earth's crust. However, pink diamonds can also be treated or enhanced through various processes, such as irradiation or high-pressure, high-temperature treatments.
Depending on the composition of 'phony diamonds', yes, genuine diamonds will probably weigh more. The specific gravity of diamonds is 3.5, which is above average.
Real diamonds -- and any other stone -- can be cut into a marquis shape and remain genuine stones or gemstones.
If those involved are genuine Christians, there will naturally be genuine Christian fellowship. This sounds rather simplistic but it's absolutely true.
Carat for carat, no gem is more expensive than a diamond, given a superior cut, clarity and colour classification. Other gems can be more expensive than diamonds when the diamonds lack top qualities.
Manufactured diamonds generally is another word for synthetic. A natural diamond can be flawless as can a synthetic. The difference is that the lab process tends to create differ ant imperfection than nature
Amazon.co.uk does not sell genuine diamond jewellery. Since you have won the lottery and can splash out a little, you can try real jewelry stores that sell diamonds.
You probably don't -- can't discern the authenticity of a diamond with the naked eye.
The term 'genuine, clean diamond' implies a generalist's description of what a gemologist would term 'natural, acceptably flawed diamond'. The term 'regular diamond' is as descriptive as 'regular human'. Any diamond is worth what someone will pay you for it.
