Beyond first brilliance.
Gemstone sourcing, assessment coordination, and provenance review for jewelry houses and independent brands.
For jewelry housesEvery selection carries a story.
A jewelry house must understand more than the beauty of a stone. Stratum Gemological helps brands align sourcing choices with their gemological requirements and the evidence behind supplier claims. We support the progression from a detailed brief to specialist review, transaction planning, and considered delivery arrangements.
