Ceannaich daoimeanan hpht air-loidhne saothrachadh daoimeanan 1 carat 2 carat 3 carat

Tuairisgeul goirid:

bha daoimeanan hpht air an dèanamh ann an obair-lann, seach a bhith air am mèinneadh bhon talamh.Chan e knockoffs a th’ annta, chan e Zircon Cubic a th’ ann an daoimeanan hpht, chan e criostalan a th’ annta.Tha iad nan daoimeanan gu ceimigeach co-ionann ri an co-aoisean talmhainn.tha daoimeanan hpht an aon rud ris an daoimean nàdarrach, prìs dìreach 1/8 de daoimean nàdarrach.

Gearr

Bithear a’ dèanamh coimeas eadar cuibhreannan iomlan gemologists, tomhasan agus ceàrnan aghaidh le sgrùdaidhean air soilleireachd, teine, spealadh agus pàtran gus an Ìre Gearraidh a dhearbhadh.
