At a time when financial markets are experiencing constant fluctuations, more and more investors are turning to\u00a0<\/span>tangible and sustainable assets<\/b>. Among them, precious stones occupy a special place: they combine\u00a0<\/span>financial value, rarity, beauty and cultural heritage<\/b>.<\/span>
<\/span>Unlike other investments, stones are both an asset and an object of art, capable of being passed on and admired.<\/span><\/p>

Their considerable value is only accelerating with growing global demand, while production is limited.<\/span><\/p>

At J\u00e9r\u00f4me Bonneville, each stone is selected for its exceptional quality, its value-adding potential and is certified. We offer you a customised, confidential and transparent investment approach.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Unlike some volatile investments, precious stones benefit from constant demand, particularly for coloured stones. Their increasing rarity - linked to the depletion of deposits - contributes to a steady rise in their value over the long term.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Royal blue\u00ab sapphires\u00bb<\/h3>

Sapphires come in all colours, the best known being blue, while the rarest is the orange-pink \u00abpadparadscha\u00bb.
\nThey must be unheated.
\nThe most sought-after blues have a saturated \u00abroyal blue\u00bb hue. The finest specimens come from Sri Lanka (formerly Ceylon), Burma (formerly Myanmar) and Madagascar.

Like sapphire, ruby is corundum.\nIt is always red, and its colour and rarity are due to the chromium.\nIt must be unheated and have a bright \u00abpigeon's blood\u00bb red colour. A perfect stone weighing more than 2.5ct is exceptional.\nThe finest specimens come from Burma (formerly Myanmar), Vietnam, Tanzania and Mozambique. \n<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Emeralds - Mineral garden<\/h3>

This mysterious stone with its deep, intense green is reminiscent of plants, as are its typical inclusions: its gardens.
