Finswimmer asked:


Crude oil is the result of Carbon based sediments which get covered by other sedimentation, if you add the right amount of pressure and heat then crude oil is the result, my question is, is there a way to replicate this process synthetically?, there are Synthetic diamonds that are created in the lab and they replicate the conditions that make diamonds form, is there a way to do the same with Crude Oil?

wikipedia defines costume jewellery as ‘jewelry that is made of less valuable materials, including base metals, glass, plastic, and synthetic stones, in place of more valuable materials such as precious metals and gems.’

yet when last weekend I took my £80 swarovski ring for repairs (caused by wear and tear on the rhodium) at a number swarovski outlets they said they don’t repair that sort of scratches (and said its still in good condition considering its 4 years old!).

One particular outlet additionally commented that swarovski jewellery are, after all, just costume jewellery. Costume jewellery does sometimes say it has swarovski crystals, and the ring doesn’t have any diamonds or previous gems; although it costs much more then the normal £5 ring you’d get from a costume jewellery shop

So my question: is Swarovski jewellery and overly expensive costume jewellery?

Is It Possible To Cremate A Person, Take The Ashes (which is made out of carbon) and Make It Into A Diamond (which is also made out of carbon) using the GE method called HPHT (High Pressure, High Temperature)?

How much would that cost?

Ethen J asked:


We all know that diamonds are the hardest natural material, but everywhere I see it, it always says that it is hardes naturally occuring material. Are there any synthetic materials that are as hard or harder than diamond

PuggetAboutIt! asked:


As in, lab created, but a real diamond and high quality. Not a CZ.

kiki asked:


Eco rings are rings that are environmentally friendly, i.e. they use recycled gold and man-made diamonds. The rationale is that gold and diamond mining are damaging to the environment and exploit human labor; thus, by using pre-owned gold and creating diamonds in a laboratory rather than getting them from the ground, we can minimize the negative impact of jewelry-making on the environment as much as possible. GreenKarat is an example of a company that makes eco jewelry.

BlackRepublican asked:


I am considering purchasing my wife a new ring that has roughly 3 carats made of synthetic diamonds. I was wondering if the synthetic diamonds would end up having a resale value comparable to that of a natural diamond or would a jeweler be able to determine that it is a synthetic diamond?

photowhxre asked:


I’ve been doing some research on lab created diamonds vs natural and I don’t see much of a difference. Plus they are way cheaper for my boyfriend who is planning on asking me to marry him. But my only question is.. If he were to get me a ring set in sterling silver, is it costly to get the ring set in white gold at a jewelers instead? I love white gold and the ring we’re looking at is set in sterling silver.

Jim O asked:


I bought a synthetic lab-generated diamond from a very reputiable company (at least I thought). When I recieved the stone it looked perfect and great. I was told it had a hardness of 9.2 and had almost all the other characteristicts of a true mined diamond. After about 2 weeks under normal everyday conditions the “synthetic” diamond was scratched. I called the company and asked them about this, and they replied by saying even mined diamonds can be scratched. Is this true? I thought a diamond could only be scratched by another diamond.

mobyisaparrothead asked:


I heard something about lab created… does that really matter in terms of an engagement ring?
