"Indeed, a woman from the wives of the people of Paradise, the whiteness of her shin is visible through seventy garments until her marrow is seen, and that is because Allah, he Exalted, says: As if they are corundum and Marjan. So, as for the corundum, it is a stone that if you were to enter a wire through it, then you polished its cloudiness away, you would surely be able to see it through it." Another chain reports a similar narration.  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الْمَرْأَةَ مِنْ نِسَاءِ أَهْلِ الْجَنَّةِ لَيُرَى بَيَاضُ سَاقِهَا مِنْ وَرَاءِ سَبْعِينَ حُلَّةً حَتَّى يُرَى مُخُّهَا وَذَلِكَ بِأَنَّ اللَّهَ يَقُولُ (كَأََنَّهُنَّ الْيَاقُوتُ وَالْمَرْجَانُ ) فَأَمَّا الْيَاقُوتُ فَإِنَّهُ حَجَرٌ لَوْ أَدْخَلْتَ فِيهِ سِلْكًا ثُمَّ اسْتَصْفَيْتَهُ لأُرِيتَهُ مِنْ وَرَائِهِ حَدَّثَنَا هَنَّادٌ حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ عَمْرِو بْنِ مَيْمُونٍ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ عَنِ النَّبِيِّ ﷺ نَحْوَهُ  

[Machine] On the authority of the Prophet ﷺ , he said: "Verily, a woman from the people of Paradise will have her lower legs exposed from seventy layers of silk, and that is because Allah says, 'They will be as if they were rubies and coral.' As for rubies, if you were to enter a thread of silk into them, then look at them from behind, you would see their beauty."  

عَنِ النَّبِيِّ ﷺ قَالَ «إِنَّ الْمَرْأَةَ مِنْ أَهْلِ الْجَنَّةِ لِيُرَى بَيَاضُ سَاقِهَا مِنْ سَبْعِينَ حُلَّةِ حَرِيرٍ وَذَلِكَ أَنَّ اللَّهَ يَقُولُ {كَأَنَّهُنَّ الْيَاقُوتُ وَالْمَرْجَانُ} فَأَمَّا الْيَاقُوتُ فَإِنَّهُ حَجَرٌ لَوْ أَدْخَلْتَهُ سِلْكًا ثُمَّ اطَّلَعْتَ لَرَأَيْتَهُ مِنْ وَرَائِهِ»
