Soortelijk Gewicht van Edelstenen — Referentietabel
Dichtheid van 130 edelsteensoorten: minimale, typische en maximale waarden van het soortelijk gewicht, aflopend gesorteerd. Het soortelijk gewicht wordt gemeten door hydrostatisch wegen — de steen in de lucht en daarna hangend in water wegen — en werkt op ruw ongepolijst materiaal, maar niet op gezette stenen.
De edelsteennamen staan in hun internationale handelsvorm (Engels) en linken naar de detailpagina van elke soort (in het Engels).

Wat is het soortelijk gewicht van diamant?
Het soortelijk gewicht van diamant is 3.50–3.53. Imitaties geven andere waarden — zirkonia is veel dichter (5.60–6.00), waardoor hydrostatisch wegen ze snel scheidt.
Welke edelsteen heeft het hoogste soortelijk gewicht?
Van de 130 edelstenen in deze referentie is Cinnabar de dichtste (8.00–8.20). De volledige tabel ordent alle soorten van hoog naar laag.
Hoe wordt het soortelijk gewicht gemeten?
Door hydrostatisch wegen: weeg de steen in de lucht en daarna hangend in water — de verhouding is het soortelijk gewicht. Werkt op losse, ruwe en onregelmatige stenen, maar niet op gezette stenen: het metaal maakt de meting betekenisloos.
