- Dè a th’ ann an Lab Grown Diamond
Tha na h-eadar-dhealachaidhean eadar daoimean nàdarra agus obair-lann a’ fàs mar thoradh air mar a chaidh an dèanamh.Bithear a’ dèanamh daoimeanan saothraichte le daoine ann an obair-lann fhad ‘s a tha daoimeanan nàdarra air an cruthachadh air an talamh.
Chaidh a’ chiad daoimeanan synthetigeach soirbheachail a dhèanamh le bhith ag atharrais air nàdar le saothrachadh Brùthadh Àrd/Teòthachd Àrd (HPHT).Tha trì pròiseasan saothrachaidh bunaiteach air an cleachdadh gus daoimeanan HPHT a dhèanamh: am preas crios, am preas ciùbach, agus am preas raon-sgoltadh (BARS).Is e amas gach pròiseas àrainneachd de chuideam agus teòthachd fìor àrd a chruthachadh far am faod fàs daoimean tachairt.Bidh gach pròiseas a’ tòiseachadh le sìol beag daoimean a tha air a chur ann an gualain agus air a chuir fo chuideam agus teòthachd fìor àrd gus an daoimean fhàs.
Is e dòigh mòr-chòrdte eile airson diamnd synthetigeach fhàs tasgadh bhalbhaichean ceimigeach (CVD).Bidh am fàs a’ tachairt fo chuideam ìosal (fo chuideam àile).Tha e a’ toirt a-steach a bhith a’ biathadh measgachadh de ghasaichean (mar as trice 1 gu 99 meatan gu hydrogen) a-steach do chamver agus gan sgoltadh gu radicals gnìomhach ceimigeach ann am plasma air a lasadh le microwave, filament teth, arcdischarge, lòchran tàthaidh no leusair.Tha an dòigh seo air a chleachdadh sa mhòr-chuid airson còmhdach, ach faodaidh e cuideachd criostalan singilte grunn millimeters a thoirt gu buil.

- C: Am bi an deàrrsadh Daoimean a’ seargadh air falbh?
A: Chan eil
C. C: Dè a chosgas an obair-lann seo fàs daoimean an taca ris an fheadhainn nàdair?
A: Tha e 30-70% nas ìsle na an tè nàdair gu diofar cuideam agus soilleireachd.
D. C: An urrainn dhut an daoimean a ghearradh gu gnàthach?
A: Faodaidh, is urrainn dhuinn an daoimean a ghearradh a rèir do riatanas.
